初中平面几何比较难教,凡教过的人都有这样的感觉。尤其对于新教科书,领会不了其精神,往往讲了一堂课以后,学生接受不了,常喊“难学”。我初教时,也感觉无头绪,不知从何下手才好,怎样才能把教材教给学生,使他们很好的吸收、消化,达到提高教学质量的目的,的确,一个新教师遇到的困难是多些。后来通过自学,刻苦钻研,减少了教学中的困难,教学效果也相应地有所提高。我学教几何是从以下几方面进行的: 一、做完书上的全部习题教者先动手做习题,不仅熟悉了教材,同时,对书中习题能够心中有数,也明确知道,习题中哪些是难题,哪些容易做。我备了本“千题集”簿,在上面做上记号“难”“易”“一般”三种类型。对于难题,就注意很好的讲解或提示,这对选择习题,控制作业份量很有帮助。另外,通过亲手做题,可以发现学生在做题中可能发生的问题是什么,早打预防针。这不仅使学生做题减少困难,教师批改作业也方便多了。在“千题集”簿上,我还常做些书外题,便于适当的加深和扩大学生的视野。同时还注意一题多解,把简易的方法交给学生,并启发他们寻求多种解法。
Middle school plane geometry is more difficult to teach, where people have taught this feeling. Especially for the new textbooks, can not understand the spirit, often after a class, students can not accept, often shouting “difficult to learn.” When I first started teaching, I felt clueless. I do not know where to start. How can I teach teaching materials to students and make them absorb and digest well and achieve the purpose of improving teaching quality. Indeed, the difficulties encountered by a new teacher Is more. Later, through self-study, study hard, reducing the difficulties in teaching, teaching effectiveness has also been improved. I learn to teach geometry is carried out from the following aspects: First, do all the exercises on the book Teachers first do exercises, not only familiar with the textbook, at the same time, the book exercises can know the difference, but also clearly know what the exercises Is the problem, which is easy to do. I prepared this “a thousand questions book” book, in the above marked “difficult” “easy” “general” three types. For the problem, pay attention to a good explanation or tips, which is the choice of exercises, control the amount of work helpful. In addition, by personally doing the question, you can find what problems students may do in the question, what to fight as soon as possible. This not only makes it easier for students to make assignments, but also makes it easier for teachers to modify assignments. On the “Thousand Titles” book, I often do some extra-curricular questions to facilitate proper deepening and broadening of students' horizons. At the same time also pay attention to a multi-solution, the simple method to students, and inspired them to seek a variety of solutions.
