Teaching Design Of Trigonometric Function Review Course Based On CPFS Structure

This research aims at the instructional design of trigonometric function review course based on the CPFS structure.The study designed the following three questions:(1)How is the mastery of trigonometric functions of senior three students at this stage and the review teaching design adopted by the teacher?(2)What is the instructional design of the trigonometric function review course based on CPFS structure theory?(3)Does the teaching design contribute to the improvement of students’ mathematics performance?The research is based on the third and fourth volumes of the B edition textbook of People’s Education Press as the research content,using questionnaire survey method and experiment al method.First,this article analyzes the structure of CPFS on trigonometric function knowledge,and then proposes methods and strategies for applying CPFS theory to review courses.Secondly,this article conducts a questionnaire survey of senior high school students and teachers,the purpose is to understand the current students’ mastery of trigonometric functions and teachers’ teaching situation,and on this basis to carry out teaching design.Finally,an experimental study was conducted in this article to test whether the instructional design is effective.The data of the pre-test papers and post-test papers show that in the two classes of the same level in the pre-test,after the teaching based on the CPFS structure design,the mathematics scores of the experimental class and the control class are significantly different,which confirms the instructional design of trigonometric function review course based on CPFS structure is helpful for students to master the knowledge.Three conclusions can be drawn from the above research: First,the imperfect construction of the CPFS structure of the trigonometric function knowledge part of the senior high school students at this stage;Second,the experimental results confirm that the teaching strategies used in teaching three different types of courses based on the CPFS structure theory are effective;Third,the statistical results show that the teaching design based on the CPFS structure theory has a significant effect on improving student performance.Three suggestions are made from this research: First,teachers should pay attention to the theoretical study of CPFS structure and teaching practice based on CPFS structure theory;Second,when using CPFS structure theory to design instruction,it is necessary to fully understand the academic situation and optimize instruction design;third,when using the CPFS structure for instructional design,the use of conceptual maps and other knowledge structure diagrams will help students construct the relationship between knowledge in a more intuitive form and improve the review efficiency.
