Reflections on Sec 4 A. Math class (9/12/2012) …

Two new students joined us ytdy, one from Monfort Sec and one from SCGS. Apparently, I tutored the latter’s cousin a few yrs ago, all the way from Sec 2 to JC2 in Math and Physics, and who is now a first year undergrad; just learnt that he scored 2 A’s and 2 B’s in his A-levels (he might have told me about it); anyway, that proves my point, that you can come from a ‘neighbourhood’ sec sch and then go to a ‘low-ranked’ JC and still do well at the A-Levels. Contrast this with the two ex-IP students that I helped this year to re-take their A-Levels. So students out there pls wake up; no one owes you good grades.

The three tutees agreed to revise some sec 3 topics instead of me teaching them a Sec 4 topic. So for this class (Sat 2.15 to 3.45pm), I will only start teaching Differentiation in Jan 2013. So ydty two of them covered Indices, Surds and Log while the remaining one wanted to revise Trigonometry. Every time, I find joy in proving to students that Logarithms is a VERY EASY topic. Once you understand what a logarithm is, everything about it becomes very easy (I’ve posted another article on Log; pls do a search on it, under A Math study tips I think).

Trigo is a much harder topic, especially the proving of some Trigonometric Identities. However, there are heuristics to use in solving the latter, and these techniques work 95% of the time. I like ‘proving’ qns because there is no answer to find, and students normally dislike such qns precisely because there is no answer to find. But I can’t blame them; imagine spending 6 yrs of your life in pri sch only learning how to find answers, so students become obsessed with finding a numerical answer, and eventually get defeated by qns that ask them to prove something already known.
