Term 1 Week 6 Tues (4E5) AMaths - Proving of Trigo Identities

Returned the 1st class test on Trigo Graphs and Ratios. About 60% of the class did well in this test. Common errors include forgetting to invert the graph (e.g. - sin x), leaving out labelling of axis and degrees and adding the degree to the basic angle (e.g. A - 30 deg = basic angle, A = basic angle + 30 deg and using this value to compute the othe quadrant solution). The class were alerted about their mistakes. The best solution is to get the class to work in group to do the class test correction together using peer tutoring. This is part of the Assessment for Learning strategy I learned on course just 3 days ago. Student tend to listen seriously to their peer feedback more than teacher's comment on whiteboard (since they can talk using their own lingo). Will try this out in the next class test (Thurs). However, this exercise will require time and may affect the teaching schedule. Started on the proving of trigo identities. Generally, the students were able to do the simple proving. They will need more practise on more challenging questions. Will gauge the class ability when they do the class assignment.
