The Analysis of Math Teaching Mode
The math teaching model of "three-in-one" is a teaching method of "self-study-inquiry-summed up".In the self-study process,the students first read the content by themselves,then the teachers explain the difficulties and summarize the key points;the contents of inquiry is to arouse the students' interest in their research and teachers conduct,give directions and correct errors with nothing omitted;the summarization part is to enable students to their own reasonable sum,and teachers analyze and evaluate it,then improve it comprehensively.To simplify complex issues is to change the difficult questions into the easy ones,and the examples into the exercises.Consider the examples in a comprehensive way,and find out the maximum method as well as the method when a certain term is changed.Carry out the multi-interactive activities of examples and exercises.
We use multiplication maps to give a characteristic-free approach to vanishing theorems on toric varieties. Our approach is very elementary but is enough powerful to prove vanishing theorems.
