A few days ago, some former colleagues at the Polytechnic University of Bucharest sent me a draft methodology for evaluating academic staff, together with its annexes and an Excel self-assessment sheet covering scientific and teaching activities. The documents attempt to encompass almost everything a university professor does and to express the result through points, rankings, and ratings.

I do not intend to advise my colleagues at the Polytechnic on how they should organize their evaluations. I observe what has been proposed and allow myself to comment, from the perspective of more than fifty years of teaching, on what such instruments can tell us about a professor and what they risk leaving out of the judgment. Before commenting on the proposal, I must explain what I mean by a professor's worth.

This essay takes the form of a dialogue: “Me” voices the author's questions and experiences, while “AI” offers arguments, objections, and interpretations. The Polytechnic proposal is our starting point, but the issue goes beyond the university: what does it mean to transmit knowledge, from school to university, and how can we judge the worth of the person who makes that possible?

The choice of dialogue recalls, in spirit, the way Plato made his encounters with Socrates occasions for exploring ideas. This is neither a transcript of a conversation nor a script intended to be spoken in a podcast. The voices “Me” and “AI” are instruments of written reflection: questions, answers, and objections help us examine a problem without pretending to have reached a verdict from the outset.

What the Polytechnic proposes

The documents I received do not form a single scoring grid. The draft methodology establishes a process of periodic evaluation; four annexes describe questionnaires and the aggregation of results; and an Excel sheet inventories activities for which points can be awarded. In the copy of the methodology I received, the dates of approval by the university's governing bodies are still blank. We are therefore discussing a proposal under consideration.

The methodology explicitly states that its aims are to improve teaching, identify training needs, and support professional development. It combines student evaluations, self-assessment, peer review, and an integrating assessment by the head of department. Under Article 18, the final classification assigns 40% to student evaluations, 30% to self-assessment, and 30% to peer review. Student evaluation results are divided into four relative groups, or quartiles (CS1–CS4), with CS4 representing the bottom quarter of the institutional ranking. According to the document, three consecutive semesters in CS4 may trigger monitoring, while five consecutive evaluations in CS4 may lead to pedagogical training or other remedial measures. These two formulations should be distinguished: “semesters” and “evaluations” are not automatically equivalent units.

The Excel sheet offers a broader inventory arranged in six chapters:

Chapter Activities awarded points
I. Education Books and teaching materials, supervision of degree projects and doctoral students, specific teaching activities
II. Research Articles, patents, grants, research contracts, and projects
III. University management Coordination of programs, laboratories, committees, and other institutional responsibilities
IV. Academic recognition and prestige Professional memberships, citations, prizes, and scientific reviewing
V. Academic community and socioeconomic environment Academic service, event organization, offices held, and representative activities
VI. Other indicators Faculty-defined criteria, capped at 500 points

Each activity has its own unit score. For example, the sheet awards 20 points for a course whose materials are posted regularly on Moodle under the stated conditions, 15 points for responsibility for a timetable committee, and, under a heading dedicated to promoting academic activities, 10 points for an eligible social-media post, up to a specified limit. Other entries award points for book pages, articles, doctoral students, grants, and citations. The Excel sheet does not specify percentage weights for the six chapters: its total is the sum of the points accumulated. The effective weight of each chapter therefore follows from the scoring rules and the volume of activity, rather than from an explicit justification of its relative importance.

The document allows the Faculty Council to approve changes to unit scores in the first five chapters and reserves up to 500 points for other local indicators. Such flexibility can accommodate different profiles, but it also raises questions about comparability across faculties, transparency, and the stability of the rules.

Me:

At first sight, the proposal seems comprehensive. A professor teaches, conducts research, works within the institution, contributes to community life, and may or may not earn professional recognition. All of these deserve consideration. But is it enough to list them, assign points, and add them up? Should we not begin with the purpose of education?

AI:

Let us be fair to the authors: the methodology does not claim that the sum of points represents a professor's human worth, and it legitimately proposes a mechanism for feedback and development. The difficulty arises when indicators are aggregated into rankings with professional consequences. We must then ask what the result represents: the quality of an educator, the overall contribution to the institution, or scientific prestige.

What are we evaluating, and why?

Me:

A professor is also an employee of an “enterprise”: he has duties toward the institution that employs him. He is also a member of a community, with responsibilities toward it. I do not deny that these contributions may be evaluated as well. But the educator's role is not the same as the others. Which matters most?

AI:

At least three dimensions must be distinguished: the value of teaching and education, the fulfilment of institutional duties, and contributions to the professional or wider community. At university there is also research, with purposes of its own. All are legitimate, but they are not alike. A good administrator does not thereby become a good educator; a highly cited researcher does not automatically acquire a gift for teaching.

The specific purpose of evaluation matters too. Improving teaching requires a pedagogical diagnosis. Promotion requires standards appropriate to the position. Assigning administrative responsibilities calls for other abilities. A single ranking meant to answer all these questions would require a justification that no formula could replace.

There is another tension: the university as an institution is concerned with revenue, visibility, accreditation, and efficient operation. Society also needs people capable of independent judgment, not merely graduates or easily counted outputs. These aims are not incompatible, but neither do they always coincide. A methodology reveals the hierarchy that the institution chooses among them.

The teacher and the loss of social standing

Me:

I wonder whether the discussion of evaluation should be preceded by a broader question: what has happened to the teacher's standing in society? Teachers are increasingly regarded as ordinary functionaries, often poorly paid and treated without the consideration they deserve. We forget that teaching is, or ought to be, a vocation. Knowing a subject does not necessarily mean being able to teach it, much less awaken in others the desire to learn. That ability gives the profession a social value that is difficult to price.

In the experience of my generation, this decline became more pronounced under communism, when the regime's proclaimed equality often encouraged disregard for differences in merit and intellectual standing. It continued in another form under the market economy, where people are increasingly judged by their material position rather than by their contribution to society. Are we not discouraging precisely the most capable people from entering teaching?

AI:

Pay, professional authority, and social esteem are different things. A teacher's work often bears fruit long afterward; its effects are difficult to attribute to one person and cannot be reduced to an economic outcome. Your historical interpretation needs qualification: communism did not eliminate every intellectual hierarchy, just as a market economy does not inevitably imply contempt for education. But both can make teachers answer to criteria external to educating students: conformity in one case, profitability and measurable performance in the other.

Me:

When the profession no longer attracts enough well-prepared people, institutions are tempted to fill vacancies at any cost. The urgency of covering teaching hours or the intervention of influential people may take precedence over competence and a calling to teach. And now, after such people have been admitted, do we want to identify them through evaluations and put them in the dock? Is it not too late? The damage has already been done, including to generations of pupils and students. Should we not concentrate above all on selecting future teachers, using quantitative criteria, certainly, but especially qualitative ones, which are harder to formulate and apply yet essential?

AI:

An institution that neglects recruitment, preparation, and support risks shifting all responsibility for the system's shortcomings onto teachers. Even so, inadequate initial selection does not render later evaluation pointless: today's students have a right to competent teachers. The question is whether evaluation aims to improve teaching or merely to name culprits. For the future, files and scores must be complemented by an assessment of actual teaching. A vocation can also develop where an institution provides examples, mentoring, and intellectual freedom.

Me:

Relations with parents have changed too. Sometimes teachers must defend every legitimate demand against parents who treat them as service providers. I do not idealize the schools of the past; I knew unjust teachers. But the loss of respect for the profession does not strike me as progress.

I also remember that one once chose teaching partly for the way of life it allowed. Long vacations gave you time to read, keep informed, reflect, rethink your courses, and simply live. Today teachers seem burdened with reports, procedures, forms, and constant demands to justify their work. When can they read? When can they construct the syntheses without which a course becomes a mere accumulation of information? Are we not keeping them so busy proving that they are working that they have no time left for the heart of their work?

AI:

Respect for teachers does not mean tolerating injustice or incompetence. Parents may challenge an abuse, but challenging abuse is not the same as denying professional authority. And time spent reading and reflecting is not a privilege unrelated to work: preparing a course requires selection, organization, and a continual reinterpretation of the discipline.

There is a paradox: in the name of teaching quality, administrative reporting can consume the very time on which quality depends. Reading an essential book or rethinking a course does not always leave an easily countable trace; a completed form does. Teachers need not only rest but time to think. In Recalcati's terms, how can they remain witnesses to their own love of knowledge if they have no time to cultivate it?

Me:

Seen this way, the proposed Polytechnic ranking troubles me all the more. I do not reject evaluation, but I fear that a hierarchy based on debatable scores may be mistaken for a hierarchy of the teachers' worth. If such rankings were also made public, would that not further undermine the profession's standing?

AI:

We must establish whether the methodology actually provides for publishing results; we cannot assume it. But even without publication the essential question remains: what do the indicators rank — the discharge of duties, performance in a particular field, or a teacher's overall worth? Society needs teachers who are accountable for their work, but also respected teachers able to exercise independent intellectual judgment. These requirements must be reconciled.

After considering the teacher's place in society, we can return to a question at the heart of every school: what happens when a teacher tries to convey something to a learner?

Can knowledge be transmitted?

Me:

Before discussing how teachers are evaluated, we should understand what transmitting knowledge means in education. The teacher explains; the pupil listens and learns. But what is transmitted? Information? Concepts? Ways of thinking? Or perhaps something of the teacher's personality as well?

AI:

The phrase “transmission of knowledge” simplifies a more complex process. We can convey information, statements, examples, and demonstrations. Understanding, however, does not pass fully formed from one mind into another. The learner must interpret, connect new information with what is already known, and become able to use it. The teacher creates and organizes the conditions for this activity but cannot understand on the student's behalf.

We should therefore distinguish teaching from learning. A flawlessly delivered lesson does not guarantee that everyone has learned; nor does the absence of a masterly explanation rule out independent learning.

Me:

How, then, do we evaluate a teacher? By what he has managed to explain or by what the students have managed to understand?

AI:

Learning outcomes are indispensable, but they cannot be attributed entirely to the teacher. Each student's prior preparation, motivation, and effort matter. We should examine both the quality of the learning opportunities provided and the progress achieved by those who use them, without confusing the two.

What does the teacher add to information?

Me:

Information can be found in books and, today, everywhere on the internet. What distinctive contribution does the teacher still make?

AI:

The teacher selects, orders, explains, and connects knowledge. He can distinguish a detail worth remembering from a concept that reorganizes our understanding of an entire field. He can identify a difficulty and change his explanation. Above all, he can reveal the significance of an idea: why is it worth knowing?

Me:

I would also call this the value, or peso cognitivo, of what is transmitted: the importance of concepts and the intellectual effort needed to understand them. Not all information carries the same weight in shaping the mind.

AI:

But the teacher cannot decide alone what will have the deepest effect on each student. The cognitive weight he attributes to an idea does not guarantee that the student will perceive it in the same way.

Socrates and learning through questions

Me:

What can Socrates tell us about this profession, about the teacher's vocation? He had no articles, projects, or patents, yet his influence on thought has lasted for millennia.

AI:

As he appears in Plato's dialogues, Socrates rejects the simple image of a teacher who possesses a doctrine and delivers it to disciples. In the Apology, his questions unsettle those convinced they know; confronting their own ignorance begins an examination of the self. In the Meno, his geometrical exchange with a young slave first leads the boy into perplexity and then guides him through a line of reasoning. In the Theaetetus, the comparison with a midwife suggests that the interlocutor should be helped to formulate and test ideas, not merely state them.

Of course, these dialogues do not amount to a complete textbook of pedagogy. The episode in the Meno also belongs to Plato's theory of recollection, which should not be confused with a modern psychological account of learning. Children must learn to read, to calculate, and many other things they cannot rediscover on their own. But Socrates reminds us that knowing is more than repeating a correct answer.

Recalcati and the desire for knowledge

Me:

My ideal is a teacher whose passion for a subject and desire for knowledge can transform a student's intellectual destiny. I think of Massimo Recalcati's book L'ora di lezione. Per un'erotica dell'insegnamento.

AI:

Recalcati places the love of knowing and the desire for knowledge at the heart of teaching. His “erotics” of teaching does not refer to personal seduction in the ordinary sense, but to the desire to know more as a driving force of intellectual life. Knowledge is not an object to be possessed once and for all: the path toward it is sustained by a sense of what is still missing, by curiosity, and by questions that remain open. A good teacher is neither a bureaucrat of instruction nor a machine for transferring data: by making a subject come alive, the teacher can turn it into something the student wants to discover.

From this perspective, a lesson may become an intellectual event in a student's life. Its theoretical content may fade with time, while the teacher's distinctive style endures in memory: the living example of a love for the subject being taught. Yet a teacher's desire to know cannot simply be passed on to a student. A teacher can open a door but cannot force the student through it. The fascination a teacher may inspire depends on the encounter between teacher and student; it is not the guaranteed outcome of a technique. Nor does a moving lesson release the teacher from the obligation to explain well.

In this sense, the teacher is a witness to a personal passion: love of knowledge is not delivered like a definition, but made visible in the way one searches, argues, doubts, and reconsiders an idea. High expectations may give a student the courage to think independently, provided they do not turn into humiliation. Style does not replace rigor; it can bring rigor to life.

The teacher as a model

Me:

I was fortunate to have many good teachers, and my career is partly their achievement. At decisive moments in professional life, when one must choose a path, the teachers one admired come to mind. Admiration does not always arise from command of a subject, but also from the way it was taught: orderly or disorderly, yet engaging; from passion for the material or an Olympian detachment from it; from general culture, sometimes even from the way a teacher dressed. A teacher's charisma is hard to define. It ought to count among the criteria of evaluation.

AI:

An admired teacher may remain an inner point of reference long after one's studies end. We remember not only what was explained, but how the teacher reasoned, acknowledged error, or approached the unknown. Such exemplary influence adds to cognitive and formative influence.

Admiration also carries a risk: an overpowering model may produce imitation and conformity. Ideally, a disciple preserves the teacher's example without surrendering personal independence.

Foiaș and Șabac: two ways of captivating students

Me:

I think of Ciprian Foiaș, who taught me functional analysis at the Faculty of Mathematics. He was the only professor at my two universities to fail me in an examination; the fault was mine. That is not why I remember him. Mathematics was the disciplinary pond in which he felt at home. He seemed not to prepare his lessons. He would arrive and try to remember what he had told us in the previous lecture, sometimes with our help. If he could not remember, he found another subject. It seemed as though he invented his proofs on the spot. Occasionally he stopped: “I've taken a wrong turn.” He erased the board and tried another way. In the lecture hall we students understood almost nothing. Only later, while preparing for the examinations, did things begin to become clear. I did not approve of this way of teaching, yet I was fascinated. I felt I was facing not an impostor but a genius, and that mattered enormously. Some took him as a model.

AI:

Foiaș fascinated you precisely because he made the process of mathematical exploration visible. But we should not confuse the memory of an already intellectually mature student with an assessment of the whole course. What happened to students who needed continuity and predictability? A teacher's authenticity does not exempt an institution from checking whether most students could learn through that approach.

Me:

At the opposite pole was Ioan Șabac, who taught Special Mathematics at the Polytechnic. He knew his lecture perfectly, down to what he would write on the board. He began in the upper left-hand corner and completed the proof or chapter exactly in the lower right-hand corner. That order was passed on to our notes and to the way we studied the subject. He gave me an eight, which I considered shameful at the time, but it is not the mark I remember.

AI:

Șabac provided a rigorously structured exposition; Foiaș revealed the freedom of exploration. These are two possible formative experiences. Yet the two memories do not prove that every improvisation, or every impeccably organized presentation, is good. They merely warn us against imposing one teaching style on everyone.

The teacher in a former student's memory

Me:

We have discussed two professors whom I can still describe after more than half a century. But my memory today is not identical to the judgment I made as a student. I distrusted Foiaș's improvisations even while he fascinated me; I admired Șabac's impeccable construction of a lecture, although I was unhappy with the mark he gave me. Later, my own teaching experience made me understand both encounters differently. How much of what I now attribute to them belongs to those teachers, and how much to the person I have become?

AI:

Memory is not an evaluation register preserved unchanged. An adult reinterprets high standards, encouragement, organization, or spontaneity in light of subsequent experience. Sometimes one discovers the value of a subject once considered useless; at other times one realizes that what seemed like authority was actually intimidation. A vivid memory is an important biographical fact, but by itself it does not prove teaching effectiveness for an entire graduating class.

Collective memory can be selective too. A professor admired by the best-prepared students may have been hard to follow for those needing more support. A less spectacular professor may have left lasting working habits. Charisma is a real experience, without necessarily producing a universal effect.

Me:

I have still earlier examples, from high school. We pupils initially judged Zlate Bogdanov, my mathematics teacher, by his appearance and rather nasal way of speaking. He did not seem someone from whom one could learn anything decisive. Yet, looking back, I owe him much of the preparation that enabled me to pass the university entrance examination with distinction. What would our evaluation of Bogdanov have been worth at the time, and what is this later realization worth?

Gheorghe Caloianu, another mathematics teacher, was clear, rigorous, and attentive to a pupil's effort. I earned good marks in oral questioning but made mistakes in written tests, to the puzzlement of us both. When I finally earned a ten on a written paper, I recovered my confidence and chose the science track, although I had previously considered the humanities because I felt inadequate at mathematics. I would not claim that one teacher alone determined my future; but I could not remove that experience from the story of my path toward a technical career.

More surprising still is my memory of Florica Negoiță, our political-economy teacher, a young committed communist. We utterly rejected the ideological content of her course and disliked her for it. Yet her method of presenting a lesson impressed me: at the outset she drew a tree of ideas on the board, then systematically worked through each branch. I rediscovered the usefulness of that organization in my second year at university, when a crisis of confidence in my own abilities made me seek a way to master a subject that was proving difficult. I had retained an intellectual habit from a teacher whose convictions I did not share.

AI:

These three memories illustrate three distances between first impressions and lasting effects: an teacher underestimated at the time can prepare a pupil thoroughly; confidence gained at a critical moment may influence a choice; and a method can outlive the content for which it was used. None of these influences can simply be inferred from popularity, marks, or a pupil's agreement with the teacher's ideas. They are personal testimonies, not measurements of an entire teaching career. That is precisely why they can complement, but not replace, evaluation at the time.

They also bring us back to Recalcati. Learning a method is valuable, but the highest stake of an encounter with a teacher remains the birth of a love of knowledge, the desiderio di sapere of which Recalcati speaks — the desire to know that persists after the lesson ends. Regaining confidence in mathematics and finding pleasure in ordering ideas may be the beginnings of such a relationship with study. We cannot reduce them to points, but neither can we assume that every student experienced them alike.

Me:

Sometimes the change in judgment is more radical still. A teacher one experienced as oppressive, perhaps even unfair at the time, may turn out, after decades of working life, to be among those to whom one owes the most. Only after entering a profession and assuming responsibilities does one understand how much that teacher's demands helped, although at the time they felt merely burdensome. This does not make injustice just; it means that the former pupil's judgment does not remain fixed.

AI:

It is important to distinguish what was formative from what was humiliating or arbitrary. Later gratitude does not justify every pedagogical method. But it shows how incomplete an evaluation made immediately after a course can be: the teacher is judged at one moment, while the consequences of the encounter may unfold over a lifetime.

Yet there is also the opposite experience, which nostalgia may conceal: a teacher who humiliates, labels, or discourages students may leave lasting wounds. That one former pupil eventually appreciates demanding teaching does not prove that every classmate benefited. A teacher's long-term influence is not necessarily beneficial; we must also listen to those whose memories are unhappy.

Me:

There is a gesture that seems significant to me: many years later, a former student seeks out a teacher. Perhaps the student wants to offer thanks, say what has become of them, or rediscover a part of their youth. Yet sometimes the reunion brings disappointment. Without the aura of the teacher one once knew, the person no longer resembles the model preserved in memory. Does that cancel the influence the teacher had on the former student's life?

AI:

Not necessarily. A teacher's influence and an idealized image of that person are different things. What a pupil learned, or the courage acquired, may remain real even if a late meeting forces a revision of admiration. Conversely, a grateful former student returning is not automatic proof of the quality of an entire teaching career. A reunion can be valuable testimony, not a verdict.

Here is another asymmetry in evaluation: the most important result may only become visible decades after a course, when no administrative form records it any longer. Testimonies from former students can therefore enrich our judgment of long-term influence, but we must consider who responds, the passage of time, and the contribution of other teachers, family, and life experiences.

Can charisma be evaluated?

Me:

If such teachers stay in our memories and influence our choices, how could this quality be absent from their evaluation?

AI:

Charisma can awaken interest, but it can also foster conformity. Popularity may reward an accessible course or lenient examinations without proving depth of learning. We can investigate formative influence through testimonies and documented examples. A teacher may also be appreciated through what former pupils become, but is not the sole author of their destinies.

The university professor's two selves

Me:

Only now can we turn to the university professor. We must distinguish two faces, two selves: the professor as scientist and as educator. Research is also conducted in institutes and companies, but educating new generations is the teacher's mission. I have known extraordinary teachers with no significant research record, and researchers with outstanding CVs who could not convey what they knew. I have also known professors who excelled at neither activity.

AI:

The distinction is essential. A valuable article does not automatically make up for a poor lecture, just as an exceptional lecture is not, in itself, a scientific discovery. Universities need both functions, but they must first be judged separately. A single score can conceal radically different professional profiles.

There is nevertheless a link: a professor must know the field deeply, as a specialist does, and keep abreast of developments. Such intellectual currency cannot be equated with a researcher's publication output. Research can enrich teaching, but the number of articles is not a direct measure of teaching quality.

Research and the formation of a future professional

Me:

University research should give students an example of activity they can draw on in their professional lives. I do not necessarily mean a professor's own projects. Studying the state of the art in the course's field is essential. Investigative activities should become a small workshop for the profession to come.

Most students will not become researchers. But many subjects they study will not be used directly in their future specialties either. That does not make those subjects useless.

AI:

We should distinguish research that produces original knowledge from the formative experience of investigating a problem. Identifying a question, studying existing solutions, comparing alternatives, and checking a result can shape an engineer who will never publish an article. The value of a university exercise is not limited to its immediate professional application.

Innovation and adaptation: an AI course for Polytechnic professors

Me:

In the same package of documents, my colleagues sent me an artificial-intelligence course intended for Polytechnic professors. It comprises 28 hours divided into seven modules. This is an interesting initiative: teachers must keep pace with changes in tools and professions. But what does completing such a course mean for one's quality as an educator?

AI:

Each module provides two hours of presentation and two of laboratory work. The seven modules address understanding generative AI, formulating and checking prompts, bibliographic research, data analysis, designing teaching and assessment, agent-based workflows, and responsible use of AI in education. Professors would compare tools and work on materials from their own disciplines.

The proposal has practical potential. But its value should be judged by the competencies actually acquired and relevant changes in teaching, not mere attendance over 28 hours.

Me:

From the message my colleagues sent me, I understand that completing the course may become a requirement for promotion. I do not dispute the need to update one's skills. But why treat a professor who is only now discovering these tools in the same way as one who already works, perhaps even conducts research, in artificial intelligence? Do we risk turning a sound pedagogical intention into another formality?

AI:

This is the difference between competence and administrative evidence of participation in training. If the aim is to develop competencies, there should be meaningful assessment and a way to recognize competencies already demonstrated. If the aim is merely to complete a course, the certificate becomes another indicator of compliance.

The conditions for passing the course, its applicability to different kinds of promotion, and the treatment of procedures already underway also need clarification. The 28-hour plan alone does not settle these questions. In the documents received, the requirement appears in a covering message, not in an independently verified final regulation.

Technical competence, critical judgment about tools, and pedagogical vocation are related but not equivalent. Certifying one does not automatically demonstrate the others.

Do we still need teachers in the age of artificial intelligence?

Me:

When I began teaching, professors were among the main gateways to organized knowledge. The internet changed that, and artificial intelligence goes further: it can explain, answer questions, and adapt explanations to a learner's difficulties. I use AI myself to explore concepts and histories and to build dialogues that advance understanding. Are we approaching the conclusion that teachers have become useless?

AI:

Only if we reduce teaching to the transmission of information. Access to explanations online does not guarantee understanding, just as repeating a correct answer does not prove independent judgment. A good teacher helps students identify important problems, recognize the limits of an argument, and connect concepts. AI can support these activities and may sometimes explain something more clearly than a teacher. But educating a person also calls for a responsible human relationship sustained over time, not merely an exchange of questions and answers.

Me:

I return to Socrates, who led his interlocutors to examine their own questions and answers, and to Recalcati, for whom a teacher's passion may make a subject an object of the desire to know. Yet our dialogues stimulate me intellectually and suggest new questions. Is that not also a way of awakening the desire for knowledge?

AI:

It is. A dialogue with AI can sustain curiosity and elicit fruitful objections. But stimulating thought through answers is not identical to bearing witness, in Recalcati's sense, to one's own love for a discipline. Through style and experience, a teacher shows how one lives through the difficulty of a proof, the uncertainty of a hypothesis, and the joy of discovery. AI can reproduce certain forms of dialogue, but generating convincing explanations should not be confused with the lived experience of someone who has devoted a life to a discipline.

Me:

I see another danger. If a student receives a well-phrased answer at once, why struggle to discover it independently? My professional experience taught me that difficulty is often part of education. The result matters, but so does the path taken to reach it.

AI:

AI can support learning by testing hypotheses, identifying errors, and offering further explanations. But it can also impoverish learning when it replaces intellectual effort that the student needs to undertake. Teachers will have to decide which difficulties must be faced without automated help, which results students must justify themselves, and how genuine understanding can be assessed. Not every difficulty is an obstacle to be removed; some are what develops the ability to think.

Me:

We reach a paradox: just as teachers lose their monopoly over information, their formative role may become more important. Perhaps the question is not whether AI will replace teachers, but whether society will recognize and support the kind of teacher we shall need.

AI:

A teacher's authority can no longer rest simply on knowing more answers. It must rest on competence, discernment, responsibility, and the ability to guide learning. Socrates reminds us of the power of questioning; Recalcati, of the power of the desire to know. Technology changes how we learn, but it does not abolish the need for judgment or for finding a personal meaning in knowledge.

What can an evaluation form measure?

Me:

I do not approach this question solely as a former pupil or student. I was a university professor myself. I know how much work lies behind a course, how differently students respond to the same lesson, and how hard it is to assess its effects. That is precisely why I do not challenge the need for evaluation. I wonder, however, whether our instruments capture what truly matters or confuse what is easy to count with what is important.

AI:

Experience at the lectern gives the question another weight. Evaluation is necessary to identify shortcomings, recognize merit, and ensure institutional accountability. But an administrative instrument cannot claim to express, through a single number, a professor's entire intellectual and human worth. The judgment must consider both what can be documented now and, modestly, the possibility that some effects will only become visible much later.

Me:

Under the influence of evaluation practices also widespread in American universities, research has come to carry considerable weight in judging academics: contracts, patents, articles, and citations. Evaluation thus becomes more quantitative and ranking easier. But does earning more research points make someone a better teacher?

AI:

Indicators provide partial evidence: the number of pages does not reveal the originality of a book, and uploading materials to Moodle does not prove that students have understood them. Yet indicators are not useless: they document activities and can make evaluation more transparent than the impressions of university committees.

The problem arises when relative position becomes a sign of inadequacy. Even if all teachers received excellent evaluations, if they were required to be divided into four roughly equal groups, about a quarter would still end up in CS4. Imagine a community of a hundred professors who all receive good or very similar assessments: the bottom twenty-five are not thereby significantly worse teachers. Conversely, being in the top quarter of a group does not, by itself, guarantee a satisfactory standard of teaching.

A relative ranking answers “How does this teacher compare with others?”, not “Does this teacher meet the standards of good teaching?” To identify deficiencies warranting intervention, the results should be compared with explicit quality benchmarks and examined in context. Otherwise, we risk treating the bottom quarter of a ranking as a category of professional inadequacy. Moreover, rewards based on points may unintentionally direct effort toward activities that earn more under the scoring grid, not necessarily teaching activities.

Me:

Imagine a professor approaching retirement, with many years of teaching behind them, who is no longer significantly active in research or administration, yet still teaches important courses well. Will that professor be deemed less valuable than a colleague who accumulates points from publications, projects, and institutional duties? And separately, if a professor repeatedly falls into the lowest quartile of student evaluations, does that prove unsatisfactory teaching? Are we not at risk of assigning a professional label without examining the situation in depth?

More generally, setting aside the Polytechnic grid, we have no articles, contracts, or patents to count for a primary-school teacher. Yet some primary-school teachers are good and others are not. Should we not begin by asking what makes a good teacher?

These are separate questions. A research score does not, in itself, determine a position in the quartiles based on student evaluations. But a relative ranking can create a misleading impression if interpreted as a verdict on teaching quality. No ranking should replace a reasoned examination of actual teaching.

More generally, we can examine command of the subject, clarity of explanations, and pupils' progress. Yet qualitative judgment is not infallible. The experience of committees in earlier decades, including under communism, reminds us how much depended on circumstances, personal relationships, and the competence of evaluators. We need explicit criteria, evidence, a right of appeal, and above all impartial committees composed of competent people.

We should also distinguish evaluating a course from evaluating its teacher. Students may value a subject but struggle with how it is taught; conversely, they may admire a teacher's clarity and availability without acquiring the expected knowledge. Neither immediate satisfaction nor exam results tell the whole story on their own.

Can unlike points be added together?

Me:

Points earned under different criteria are different in nature. Some may matter more than others. How can they be added as though they measured the same quantity? An educational activity, a citation, and membership of a committee are not units of the same substance.

AI:

Mathematically, numbers can be added. But that operation does not automatically acquire evaluative meaning. The institution must explain why heterogeneous results have been converted to a common scale, why particular weights were chosen, and, above all, why one activity is allowed to compensate for another.

A multicriteria model can be useful for a well-defined administrative decision. Yet it does not become a natural measure of a professor's worth. Its coefficients embody institutional choices that may be open to challenge.

Me:

Then a professor who teaches poorly but is very active in research or administration may achieve the same total as someone who educates students exceptionally well but earns fewer points elsewhere. What does their equality tell us?

AI:

It may tell us that their contributions are equivalent under the chosen rule, not that the professors are equivalent. Legitimate multicriteria methods exist for aggregating heterogeneous results, but they entail explicit choices about weights and about compensating for weaknesses with achievements in other categories. Some requirements, such as minimum teaching competence and integrity, should remain non-compensable.

An evaluation sheet is also an instrument of institutional policy. Through its criteria and rewards, a university makes certain activities more visible and encourages a particular professional profile. The question “Who sets the points?” is ultimately “Who decides what kind of university we want?”

What might a fairer evaluation look like?

Me:

I do not question a university's right to evaluate its employees or their obligation to participate in institutional life. Nor am I trying to write the Polytechnic's regulations; that responsibility belongs to its academic community. But criticizing a total score is not enough. What principles might protect evaluation from the arbitrariness of both personal impressions and numerical coefficients?

AI:

A practical alternative might have four distinct dimensions, presented together at each evaluation:

  • Teaching and education: observation of a sample of activities by trained colleagues; review of materials and assessments; student questionnaires interpreted in light of the subject and response rate; evidence of progress; and a compulsory minimum standard.
  • Research: expert examination of significant contributions and their originality, with bibliometric indicators used as supporting information.
  • Institutional and community responsibilities: a record of tasks performed, an assessment of their quality, and recognition of service to colleagues, separately from pedagogical value.
  • Reasoned synthesis: a profile of strengths and weaknesses, discussed with the professor and open to appeal; a global index, if any, only for a precisely defined decision, not as a universal label.

Interviews with former students could periodically offer clues about long-term influence, without attributing their whole professional development to one professor. They should not be restricted to successful graduates or those who keep in touch with the university; different experiences, including less favorable ones, should also be sought. The useful question is not merely “Did you like the professor?” but “What way of thinking or working did you retain from that professor, and how did your understanding of the influence change over time?”

Me:

Such a procedure requires time and people capable of sound judgment. Is it not easier to use a scoring algorithm?

AI:

It is easier and sometimes more reproducible. But convenience does not establish validity. Peer review can become arbitrary if it is not documented; numerical evaluation can become arbitrary if the weights lack justification. The answer is not to choose between people and numbers, but to require evidence, explanations, and scrutiny for every judgment.

A conclusion that remains open

Me:

We began with a spreadsheet and arrived at the question of what it means to be a good teacher. We have discussed the loss of social standing, the selection and preparation of teachers, the time needed for reflection, and the changes brought by artificial intelligence. An institution has the right and duty to evaluate its employees. But before awarding points, should it not say what education aims to offer students and what part teachers play in achieving that aim? The AI course shows a desire to adapt. Yet the central question remains: what real competencies do we want graduates to acquire, and how do we know they have acquired them? What was their teachers' contribution? What portrait of a good teacher emerges from all this?

AI:

We ask a teacher to know the subject deeply, make ideas intelligible, be honest in the face of truth, and foster the learner's intellectual autonomy. In fortunate circumstances, a teacher can also awaken a passion that outlives the lesson and becomes a landmark of an intellectual life.

We cannot produce valuable teachers merely by evaluating them more rigorously. We must make teaching attractive to capable people, select them thoughtfully, and give them the time and intellectual freedom to go on learning themselves.

We cannot measure all of this precisely, nor should we abandon evaluation. We must acknowledge the limits of indicators and give reasoned professional judgment its proper place. A form may serve university administration; it must not be confused with the definition of a teacher.

What kind of teachers does society want to cultivate, and what is it prepared to do to have them? The dialogue remains open.
