Deepening Comprehension of Concepts in New Curriculum Standards through "Teaching Activity"
———Reflection on Sine Theorem in Teaching Activity "the Same Lesson with Different Teaching Methods"

This article deals with the Sine Theorem in the version A of compulsory course, velum 5 published by people's Education Press. It is the fist section in chapter 1. "Solving Problems about Triangle". The article proceeds from the Sine Theorem, combined with "The same lesson with different Teaching Methods" activity held by school, bringing up new interpretation about the new curriculum standards in three aspects: First, the assumed situations should be related to reality. Second, in formula derivation, emphasis should be placed on process. Third, the way of thinking should be embodied in explaining the examples.

The article proceeds from the Sine Theorem, combined with "The same lesson with different Teaching Methods" activity held by school, bringing up new interpretation about the new curriculum standards in three aspects: First, the assumed situations should be related to reality. Second, in formula derivation, emphasis should be placed on process. Third, the way of thinking should be embodied in explaining the examples.
