[Year 12 IT Apps] Potts Ch 3 and Study Design

Tue Feb 13 09:17:13 EST 2007

Hi Keith,
I have a number of videos but no the one about the Big W info system.
Where can I get it?

The approach I use (in covering the plethora of stuff to be memorized)
is I DO NOT TEACH IT.
How do I justify that? There is simply too much and lecturing almost all
of the time switches the kids off (IMHO).
Solution - my kids have to make summaries of the chapters (one per
fortnight) plus some scenarios and sample questions. Reward - they are
allowed to take their own summaries into each sac.
So what do I do with class time? Plenty of practical - let them keep
their hands on computers much of the time. Plenty of short sharp
discussions to whet the appetite/enthusiasm, answer some questions they
might have about what they are reading for homework (emphasizing that
the teacher is only one of many resources available to aid learning).
I have a number of videos such as the study of the info system used in
Big W - this provides a wonderful opportunity for them to identify some
of the stuff they are learning as they summarize.
I am not saying mine is the best approach, just that it seems to work OK
for me.
Cheers, Keith
