Vapour Pressure and Parental Pressure

A morning walk, in theory, is about steps. In practice, it is about conversations.

A couple of days each week, our walk does not quite end at the lake. It merely relocates. Three of us have been regulars for over two years now, steady in pace, steady in companionship. Others who frequent the path occasionally drift toward us when our discussions grow animated enough to demand an audience.

Examination season, however, adds a certain sharpness to these gatherings. Parents who walk alongside us carry visible concern. The topic lately has been consistent: academic pressure, perceived indifference toward studies, and the puzzling priorities of children preparing for board examinations.

A few mornings ago, one such parent spoke with unmistakable anxiety about the child’s lack of seriousness. I ventured, cautiously, that if indifference is what we observe, perhaps the question should not be confined to the child alone. Were we, in our own youth, models of unwavering academic focus? Or did we too wander, procrastinate, and selectively prioritise?

Instead of aspiring to manufacture the “ideal student,” perhaps we might reflect on what in our own expectations, comparisons, or subtle pressures shaped the present situation. Parenting, I suggested, may be less about demanding brilliance and more about facilitating growth. Rather than comparing children with the brightest in the class, perhaps we ought to help them become better versions of themselves.

That thought lingered and expanded.

Today after our walk, I remarked to my two regular companions that classroom education today seems to have lost its exclusivity. Not its value, but its monopoly. The modern student has access to structured online platforms, interactive tools, recorded lectures, and increasingly, AI-driven learning modules. Knowledge is no longer confined to a blackboard and chalk.

Perhaps, I suggested, formal education could evolve into guided self-learning,  where students explore concepts independently and teachers function more as clarifiers, moderators, and mentors rather than sole transmitters of information. Instead of spoon-feeding, classrooms might become spaces for refinement and deeper inquiry.

At this point, one among us, a distinguished chemistry professor with over four decades of teaching experience across Karnataka, a doctorate to his credit, and former Secretary in the Government’s Science & Technology department,  intervened firmly.

He objected to what he described as my “sweeping statement” about classroom irrelevance.

To advance the debate, he proposed a test. He would pose a question and examine AI’s response.

The question was simple:

“Why should salt not be added in the beginning while cooking?”

The AI response included, among other explanations: When salt is added to water, the boiling point increases slightly. Salted water boils at a temperature slightly higher than 100°C.

The professor observed that the answer did not explicitly mention that more energy is required due to reduced vapour pressure, a principle first articulated by François-Marie Raoult.

His point was that the explanation lacked conceptual depth.

I responded that stating “salted water boils at a higher temperature” is, in effect, communicating the same principle in simpler language. The underlying science, lowered vapour pressure requiring additional energy input, is embedded within that statement. What determines the depth of understanding is not merely the answer provided, but whether the student is trained to ask the next question:

Why does it boil at a higher temperature?

What does that imply about energy and vapour pressure?

In that moment, as though scripted for dramatic timing, the very parent who had spoken earlier approached us, this time accompanied by the son, a 12th Standard student whose board examinations were to commence the next day.

The debate suddenly had a live case study.

I asked the young man directly whether he preferred classroom teaching or AI for understanding concepts.

Without hesitation, he said he preferred the classroom.

There was a quiet sense of validation among some of us.

But he continued.

He clarified that he also used AI. Sometimes during lectures, he would miss a portion of the explanation. At times, he hesitated to raise a doubt, especially if the teacher had moved ahead. Occasionally, he admitted candidly, his mind wandered. In those moments, AI became a helpful companion, allowing him to revisit concepts privately, without embarrassment.

There it was, not replacement, but reinforcement.

The classroom offered structure, authority, shared experience, and discipline. AI offered repetition, patience, and non-judgmental clarification.

The young student’s answer dissolved the rigidity of our debate far more effectively than our arguments had.

The question, therefore, may not be whether AI can replace the classroom. It may instead be whether the classroom can evolve to incorporate AI meaningfully.

Technology has disrupted many industries by rendering older systems obsolete. But education is not merely an industry. It is a human process. It involves not just the transfer of information but the cultivation of judgement, curiosity, resilience, and confidence.

AI can explain boiling point elevation. It can generate multiple examples, simplify equations, and repeat explanations endlessly. It does not tire, does not lose patience, and does not mind being questioned repeatedly.

But a teacher can read a face, detect confusion, challenge complacency, and inspire aspiration. A classroom can create collective energy, the silent competition before examinations, the relief after a difficult test, the reassurance that others share the same anxieties.

What today's morning’s exchange revealed was not the inadequacy of AI nor the redundancy of classrooms, but the inadequacy of framing the issue as a binary choice.

The student preferred the classroom.

He relied on AI.

Not as a substitute.

As a supplement.

Education need not defend itself against technology. It must redesign itself around it.

Let AI handle reinforcement, revision, and retrieval.

Let teachers handle nuance, mentorship, and intellectual discipline.

Let classrooms become spaces of discussion rather than dictation.

The true challenge is not whether AI can articulate vapour pressure as precisely as a seasoned professor. The challenge is whether we can train students to think beyond the first answer, to ask the second and third “why.”

Between vapour pressure and parental pressure lies a simple truth: education must evolve.

Not by abandoning tradition.

Not by surrendering to technology.

But by integrating intelligence, artificial and human alike.

And perhaps that is the real lesson our morning walk offered, that progress does not demand replacement. It demands refinement.

Stories, not instructions. Experiences, not advice—medical or otherwise. Data, only what the internet quietly gathers anyway. Proceed with equal parts curiosity and common sense.
