Deepen The Textbook Teaching

Both teachers and students in high school are suffering from the superabundant mathematics exercises as the load is believed to be far more than any other subjects, which forms one of the main reasons for the students to sit heavy on. Teachers in the past put much time and many efforts in the * so-called "exercises sea tactics", but students still can not achieve good ideation as well as the examination results .,In the recent years, thanks to the recognition of the agile and integrative application of the basic knowledge as the college entrance examination focuses closely on the general outline of the texts, teachers hence have an opportunity to pay much attention to working over the texts, laying solid foundation and fostering ability for the students.This article describes, through teaching practice, mainly on how to "press close to the texts while insist on necessary versatility", it includes:1. Design the scene of the question so as to introduce the topic , emphasis on the knowledge process.2. Focus on variational teaching in order to reveal the conation of the questions .such as :change the condition or result of the examples in the text to form the new questions ;revise the examples in the text to form the open questions in order for the innovation ;exploit the solutions of the examples in the text to investigate on the possibility of the multi-answer .3. Pay attention to the summary of the knowledge in order to brush up the sum up ability of the students .4. Emphasis on the application of mathematics via establishing the relationship between the examples in the text and the actual problems inthe life .5. Inspire the learning interests by introducing the mathematicshistory and the aesthetics during the presentation in the class.
