数学思想方法是高中数学精华,是解决数学问题的锐利武器。立体几何是高中数学的主要章节,丰富的数学思想方法就蕴含在其中。在面对立体几何学习时,仅仅靠大量的题海战术和无目标的训练是很难达到教学目标的。本文结合笔者在长期教学中的教学实践,探讨高中数学“代数”思想在立体几何中的应用。 Mathematical thinking is the essence of high school mathematics, is a sharp weapon to solve mathematical problems. Three-dimensional geometry is the main section of high school mathematics, rich in mathematical thinking methods are contained therein. In the face of three-dimensional geometry learning, only by a large number of sea tactics and goalless training is difficult to achieve the teaching goal. This article combines the author’s teaching practice in long-term teaching to explore the application of high school mathematics “algebra ” thought in solid geometry.
