For Teachers
The author thinks that the ideal method to use this book
for instruction in a course involves the following aspects.
- The last piece of advice is perhaps the most important.
You may like to read that first.
- Match the contents of the book with your intended syllabus.
Decide on topics that is must for your course, but are absent in
the book. (Sorry for the omission.) Make lecture-size insertions
at appropriate locations.
Among the existing chapters (supposed to be lectures), decide on
adding and removing asterisks, in the sense of exclusion and
inclusion for your course.
- Now, compare the total number of lectures against the
available number of lecture hours. Fine tune and consolidate
the course plan. Plan the grading scheme.
- To the extent possible, execute lectures in the current
order. Try to keep the leture boundaries same as the boundaries
of chapters and your inserted modules.
- For a chapter somewhat larger than a lecture hour, it is
better to leave a section with a brief outline, instructing
the students to read up the matter, rather than breaking the
modularity into a continuous chain of talk across lectures.
- At times, you may decide to break a chapter into two
lectures and end up with a free 20-25 minutes out of the
second lecture hour. Do not embark on the next chapter.
Invite general questions and discuss. May be, take a quiz.
- One of the tricky issues of classroom instruction is
the use of slides. If you do not like their use and prefer
to stick to the board-work, then I am your friend. 'Development'
of ideas and arguments in the class is perhaps the main value
of the classroom. However, the professor writing down huge
dummy matrices or 10-line algorithms for the purpose of reference
is sometimes boring and unfocussing! So, I sometimes resort
to a combination of slides
and board-work. If you too plan to follow a similar strategy,
you may like to consult or try out
my set of slides.
- Ask the students to read up a chapter before the lecture
in which it is going to be covered. Encourage them to attempt
all exercises of the covered chapter, if possible. But, do
release the short selection list
for those students who might find the complete exercises too
challenging in terms of speed and maturity.
- If your course has a provision for tutorial sessions, then
finalize the tutorial problems for every such session and have
a discussion with the tutors. You can find one such set of
tutorial problems in my own
tutorial plan, which includes
mostly non-trivial and/or conceptually rich exercises in which
majority of students may need some guidance. Note that students
are likely to be receptive to these tutorial problems mostly
'after' they have attempted some exercises in the corresponding
chapters on their own.
- The appendix contains enough information in the way of
solution outline. Still, there may be occasions when an
instructor may feel the need of looking at the author's full
step-by-step solution, possibly for verification and conflict
resolution. In such cases, an instructor is requested to
write to the author. However, response to every such query
would need non-trivial effort on the part of the author.
Besides, a point is made to share such a piece of information
with teachers only. Therefore,
- the query/requisition should be limited, pointed and
non-trivial, and
- the antecedents of the person making the query should be
clearly stated.
- At the end of the course and before the final examination,
explore the possibility of compiling a set of quiz questions
and conduct an oral quiz of duration 3-4 hours, with a break in
between. It actually works, it gives a thorough revision just
at the right time and it is a lot of fun.
- While planning and executing your course, if you keep
forgetting these pieces of advice from this colleague, then
perhaps you have hit upon your own favourite strategy.
That may be the best strategy to stick to.
