Those who can, do; those who can't, teach.\u201d This quote has been ascribed to many people. No, Woody Allen\u2019s punchline in Annie Hall isn\u2019t the first reference. If credit is to be given, we should stick to George Bernard Shaw, in Man and Superman (1903). The idea\/line occurs in the main text of the play, as well as in the appended Maxims for Revolutionists. In the former, \u201cDon\u2019t listen to her Bob. Remember those who can, do; those who can\u2019t, teach.\u201d In the latter, \u201cHe who can, does. He who cannot, teaches.\u201d There is no reason to presume these were Shaw\u2019s views, as opposed to a clever witticism pronounced by a protagonist in a play. For example, on education, the maxims also include the following. \u201cWhen a man teaches something he does not know to somebody who has no aptitude for it, and gives him a certificate of proficiency, the latter has completed the education of a gentleman.\u201d The word \u201cteacher\u201d (teach) has an etymological origin such that a teacher means someone who points out and shows a direction. This requires interaction between teacher and student, guru and shishya. Successful teaching is individual-specific and a successful teacher adapts according to capacity and receptivity of recipient. That\u2019s the reason we harp on low student\/teacher ratios, if we talk about a class. Lower the ratio, more individualised the attention. Ideally, the figure should be 1:1. But with too many students and too few teachers, we must have classes, not individuals. Thus, deviations from 1:1. In passing, student\/teacher ratios are generally lower in relatively rich countries and higher in relatively poor countries. Without getting into specifics of regulatory norms, we have implicitly assumed student\/teacher ratios will decline as we move up the education ladder. Therefore, 30:1 or 35:1 is acceptable in schools, but it must decline to 25:1 for under-graduate and 10:1 for post-graduate or professional courses. At PhD level, it will clearly be 1:1. In other words, we recognise the 1:1 guru-shishya interaction as ideal, but deviate on grounds of scarce resources\u2014too many students, too few teachers. The lower range of the education spectrum is like an assembly line, individuality is left for the upper range. For students, we increasingly repress individuality\u2014in curricula, teaching and examination methods. The lower down the education ladder, the more accentuated this is. Therefore, at school level, gone are the days when students wrote essays, with subjectivity built into answers and evaluation. Instead, we must approximate multiple choice type objective questions, where computers can also perform evaluation. But then, as we move up the education ladder and progress towards the job market, we want some criteria to gauge the applicant\u2019s individuality and USP. However, since we have progressively reduced students to commodities, there is no option but to raise the bar or filter higher. Earlier, an under-graduate degree ensured differentiation. That role shifted to post-graduate degrees. In academia, that role later shifted to Ph.D. degrees. Subsequently, it shifted to publications. Still later, it shifted to citations. Teachers have also been reduced to commodities. There is a difference between a good and a service, even though technology blurs the difference and goods often come bundled with services. A service requires direct interface between the producer and the consumer. A typical service cannot be stored, and teaching is a service, though a video of a teacher delivering a lecture can be reduced to a good. Despite excitement about technology and the net, I think good teaching, or good anything that is a service, is intrinsically interactive and unique. It cannot be replicated. It is 1:1. A least common denominator can be replicated, as a template. But anything beyond cannot be standardised and made uniform. Shaw was known not just for his plays, but also for prefaces to the plays, often more interesting than the plays themselves. I should thus quote from the preface to Man and Superman. \u201cThe city papers prate of the competition of Bombay with Manchester and the like.\u201d Superior service is not about the industrial revolution and producing the service at least possible cost. Yet, for teachers, and for others, we now have the phenomena of power point presentations. Typically, this means a standardised template, devoid of any interaction and uniqueness. Shaw might well have said, \u201c\u201cHe who can teach, does. He who cannot, uses power point presentations.\u201d In the PPT mode, we don\u2019t really need the teacher. A PPT is meant to eliminate the teacher. In a relatively labour scarce country, we desire to use technology as a substitute for labour. Does a relatively labour abundant country aspire towards that goal? This is not just about teaching. Teaching is an example of a service. If India\u2019s strength is in services, and not in classic manufacturing, we should celebrate uniqueness and not seek to standardise, trying to produce Model T-s cheaply. I do not wish to posit this as either It isn\u2019t. But, I think, in branding India and musing about Make-in-India, we have focused inordinately on low-cost production. A brand distinguishes itself from a commodity by commanding a premium. It commands a premium because of quality and by virtue of being rarer, not generic. Traditionally, we haven\u2019t produced generic items. There weren\u2019t hundreds of pieces of muslin that could pass through a ring. Pieces were unique. With quality ensured, let\u2019s not always worry about economies of scale and scope. There is scope for scaling down.
