勾股定理在几何里具有非常重要的地位,是解三角形的重要基础,也是整个平面几何的重要基础,其在现实生活中也具有普遍的应用性.在数学教科书中,勾股定理一般出现在八年级,而八年级被认为是学生学习数学的一个重要发展阶段,也即具体思维向形式化思维转变的时期.所以可以说,勾股定理教学也处于学生数学思维转折阶段.但另一方
The Pythagorean theorem plays a very important role in geometry and is an important foundation for solving triangles and an important basis for the entire plane geometry. It also has universal applicability in real life. In mathematics textbooks, the Pythagorean theorem generally appears in Eighth grade, and eighth grade is considered to be an important stage of development for students to learn math, that is, from the specific thinking to formal thinking, so it can be said that the Pythagorean Theorem Teaching is also in the turning point of students’ mathematical thinking, but the other
