解三角形的课题式教学研究
Research on Project-Based Instruction of Solving Triangles
摘要
Abstract
The content of the solving triangle module is scattered in various school stages.If teachers lack macro control over the teaching materials,it is easy to separate the logical connections between various knowledge points,bringing certain obstacles to students'construction of a complete and organic knowledge system,which is not conducive to the effective connection between junior and senior high schools.By reviewing the history of Trigonometry and the combing of the internal logical relationships among the solving triangle module,this paper analyzes the content of the triangle solution module in middle school mathematics textbooks,including spiral and logical considerations,situational issues,and connection issues between middle and high schools.On this basis,the study constructs a project-based instruction framework of the solving triangle module in accordance with project-based instruction theory,also focuses on exploring the sub-topics of general triangles,namely cosine theorem and sine theorem,which will assist students in constructing a complete knowledge system of solving triangle and provide a new idea for mathematics connection teaching in junior and senior high schools.关键词
