Teachers need to understand the essence of middle school mathematics knowledge from a high perspective. In addition, the frequent appearance of questions with a background in advanced mathematics in the college entrance examination also puts higher demands on students’ cognition. Ptolemy’s theorem describes the quantitative relationship between the four sides and diagonals of a circle inscribed with a quadrilateral, playing a unique role in the geometry of circles. It can be used to solve geometric problems related to circles, as well as to construct special circles inscribed with quadrilaterals to solve algebraic problems. By geometricizing algebraic problems, many problems can be solved more conveniently and simply. Through the study of the various applications of Ptolemy’s theorem in high school mathematics, this article aims to stimulate students’ interest in mathematics, improve their understanding of mathematical concepts, provide effective teaching tools for teachers, enable students to have a deeper understanding of mathematical knowledge, and flexibly apply learned concepts in practical problems.展开更多

A comparative analysis of the mathematical operation thinking, content arrangement, and difficulty level of example exercises in the plane vector chapters of the three textbooks versions: PEP Edition, Jiangsu Education Edition, and IBDP Edition (referred to as Haisen Edition), yields some meaningful suggestions. Furthermore, through survey interviews with teachers using different textbooks in various regions, combined with specific teaching environments, we summarize and propose recommendations for textbook usage and classroom instruction. It is hoped that these suggestions will be beneficial to guiding high school mathematics classroom teaching and expanding students’ mathematical knowledge systems.展开更多

How to apply constructivist learning theory in middle school mathematics teaching, stimulate students’ learning enthusiasm and initiative, and improve learning effectiveness, is a problem that current educators need to explore and research. This article is based on constructivist learning theory, exploring how to promote students’ self-construction in middle school mathematics teaching, and proposing some teaching strategies and methods. Taking congruent triangles as an example for specific analysis and research, it aims to provide some ideas and suggestions for middle school mathematics teachers.展开更多

It explores activity designs aimed at enhancing junior high school students’ mathematical abilities based on the satisfaction of three fundamental psychological needs: autonomy, competence, and relatedness. Proposed activity design schemes including self-directed learning, cooperative learning, and competitive games, analyzed the impact of these activities on students’ mathematical abilities and learning motivation, summarized the application strategies and related inspirations of self-determination theory in actual mathematics classroom teaching.展开更多

At this stage, different regions select different versions of textbooks based on their actual learning situations. Among them, the high school mathematics textbooks of Beijing Normal University Press (BNUP) and People’s Education Press (PEP) differ significantly in curriculum design, instructional content arrangement, and logical organization. This article takes the section on the parity of functions from PEP’s “Mathematics 1 (Compulsory) A Version” and BNUP’s “Mathematics 1 (Compulsory)” textbooks for high school students as the research object. It conducts a comparative analysis from three aspects: textbook compilation concepts, content arrangement, and requirements for students. Through the comparative analysis, similarities and differences between these two versions of textbooks in terms of compilation concepts, content arrangement, and student requirements are identified.展开更多
