数形结合是一种重要的数学思想,它可以使某些抽象的数学问题直观化、生动化,能够变抽象思维为形象思维,有助于学生把握数学问题的本质。因此在高中数学教学中应该有效渗透数形结合思想,提高学生的思维能力和数学素养。本文结合自己的教学实践,阐述了如何使用教材对数形结合思想进行有效渗透,使学生逐步提高数形结合的能力。
Combination of numbers and shapes is an important mathematical thought. It can make certain abstract mathematical problems intuitive and vivid, and can change abstract thinking into thinking in terms of images, helping students grasp the essence of mathematical problems. Therefore, in high school mathematics teaching, we should effectively penetrate the combination of number and shape to improve students’ thinking ability and mathematical quality. Based on my own teaching practice, this essay expounds how to use teaching materials to effectively infiltrate the idea of logarithmic conjunctions so as to enable students to gradually improve the ability of combining numbers with forms.
