### Towards 3 Dimensional Education

[A repost of a memo (between colleagues) I had written when I was a university teacher] It was written for other faculty-members and is still very sketchy out here.  The 3 dimensional education table is the main reason for exhuming it for this blog.

For centuries grades have been 'marks-out-of-hundred'. The complaints
against this are:

1. The difference between 32-fail and 33-pass, 74-1st class and 75-distinction
etc. is ridiculously fine.
2. 33% with a tough paper may in fact be higher than 50% with an easy
paper.
3. Flattening out the infinite, multi-dimensional variety of human potential
into a finite, linear actual loses information, usually vital information.
The letter grading scheme which has become popular in the last couple
of decades solves (a) and (b) but not (c) which is exacerbated. It is possible
to envisage that a student getting 77% may in fact understand less than
one getting 74% but it is much more difficult to see that an O may – for
certain purposes – be worse than an A.

How?

Consider a paper with 5 questions of 10 marks each taken by two students
X and Y. X does everything close to correct but nothing exceptionally –
8 out of 10 in each, ie 40 marks or 80%. Y answers two questions brilliantly
– better answers than the instructor knew, new insights etc. He gets full
marks 10, 10. The next two questions are done only partially, he gets
4 and 5. And the fifth is left unattempted. He gets only 29 marks, not
even 60%.

### The Issues

So the first question is: Does our grading scheme convey too much
or too little information?

Clearly if we feel less is better, then a 5-point scheme is better than
a 6-point scheme is better than a 100 mark scheme. It does not seem to
me that this is the way any of us look at it. Even those who are asking for
a 5-point scheme (remove O, divide by 5 not 6) are asking this to align our
presentation with standard practices. In fact the other proposal — a half-page,
reco-like grade — is in quite the opposite direction. In fact, it seems
to me that:
• rules being approvable
we would all like to go towards more information rather than less.

The more fundamental question to ask is: What is it about our educational
setup that is unsatisfactory?

This is the real question and – as usual – we dont ask it because we
have only vague answers to it. As a first approximation to an answer let
me suggest that
1. The default norm of higher education is overspecialization
2. The default intellectual state of students is boredom and confusion
3. The default emotional state of not just students
is anxiety and isolation
In other words modern education
1. is linear and narrow where it used to be broad
2. is flat and meaningless where it could have body and life
3. is disconnected from the primal needs of the human being
In short, if we could look past the religious trappings, ancient or medieval education provided connections and a hope of fulfilment.
Modern education creates disconnection whose hopeless conclusion is insanity.

The following proposal for curriculum design and grade assignment may
seem to be a solution whose scale is disproportionately small as compared
to the problem. Please read it as one small part of the solution and not
the solution.

It is emerging that a course – if it is a coherent unit – can be
conceptualised, studied, evaluated, and therefore graded at 3 levels
or dimensions. A 3-dimensional grading scheme gives a mid-point between
a single mark or grade which loses too much information, and a detailed
`reco-like' essay or report by the teacher on the student which is administratively
infeasible due to lack of a summarising figure. What these dimensions
are – their names – differ, and this is only natural considering that
courses are vastly different not just in content but in orientation. However
the separation of 3 almost orthogonal directions seems possible and worthwhile.
In the following table are listed some of the many different possible names.

Notes:
1. This table is not rigorous in any sense.
2. The purpose of the table is to give a sense of the 3 dimensions. However
running down a dimension column makes no sense. Please take it one row
at a time with the left entry giving a feel for a human type or field whose
three orientations would be as given.
3. The first two rows (a,b) are the ones a colleague and myself started off with.

### Open Questions

1. Syllabus: A colleague has demonstrated a 3-d structure for P2 (Programming
tools and techniques)-- a seemingly difficult candidate (Appendix). It is
now just a question of working out the same for all courses.
2. It is seemingly more work -- but how much more? Anyway, when we correct
a paper having say 6 questions, we have to correct the 6 questions and
then add up. The only thing that now changes is that the 'add-up'
function becomes a 3-way addup. In fact it may be less work because many
times we have to struggle to incorporate a vague impression in terms of marks.
Now it just has to be recorded under a different head.
3. How do we assign the relative weightage of the three dimensions? Some
possibilities:
1. Equal weightage. Administratively the simplest solution but not sensible
considering the different types of courses.
2. In view of the fact that we are a 'science' department we could have
1 for technology, 2 for science, 1 for philosophy. This may be fine as an
overall representation of the department's flavour but would be inappropriate for individual courses.
3. Pre-declared for every course: Make it part of the syllabus
4. Late Binding: The instructor decides at the beginning of semester.  Serves as a way out for those instructors that don't like or believe in
the system. eg If the networks teacher believes there is no science or philosophy (or should not be any) in networks he may assign a weight of 0 for levels 2 and 3.
5. Could be even later – per test/assignment
