Investigation On The Current Situation Of The Three Views Of Mathematics Teaching In Senior High School

Three View Drawing helps students develop their geometry and spatial abilities, also it helps students build space conception from perception degree to the degree that students can grasp. At the same time it is also the content that is adopted in College Entrance Examination. However, owing to the lack of relative researches and materials, there is some confusion for teachers and students in the teaching.This research is qualitative based on the different teaching procedures of Three View Drawing. The questionnaires to teachers and students are adopted in this research. There are 350 valid students'questionnaire,67 valid teacher'questionnaire in this research. The SPSS and Excel are adopted to analyze these questionnaires. The research is organized from five aspects:the teachers'and students'impression on Three View Drawing; their knowledge about Three View Drawing; the current problems existed in teaching; the situations of using the information technology to assist teaching and the relative situations of students'learning. At the same time, the tests are adopted to check students'knowledge about Three View Drawing, and then it analyzes the consequence.According to the questionnaire and analysis of test, the results can be concluded in Three View Drawing teaching. Students are satisfied with the teaching schedule and teaching methods about Three View Drawing, however, their interests in it is not be stimulated fully. It varies from their test's scores and gender. There are some problems existed in teaching. In addition, teachers still do not master the New Curriculum Standard correctly, especially, they are not able to transform Three View Drawing to the simple geometry. They should take students'conditions into their consideration when they select the exercises. Teachers should take the full advantage of information technology, and the textbooks are still need to be optimized. Based on the problems above, it put forward 9 suggestions:Teachers should stimulate students' interest in Three View Drawing, and they should take the gender and tests'score into their consideration. Based on the correct understanding about New Curriculum Standard, the exercise should be more suitable to students' conditions. Teachers should pay more attention to the method of transforming the Three View Drawing into the simple geometry and the transition period between junior and senior middle school. Besides. Teachers should utilized the information and technology scientifically and optimized the content of textbooks according to the New Curriculum Standard.
