“代数繁,几何难,物理难于上青天”形象地说明了学生在物理学习中的困难之大。究其原因主要是:物理学属于一门自然学科,课本上的知识多是人们在以往的生产、生活和科学研究中逐渐积累起来的。对学生来说,纯属间接知识,这其中有不少知识很抽象,难以为学生所理解和接受;同时,在现行的教学条件和设备的局限下,演示实验、学生实验很难开足、开齐;在过去的物理教学中,限于生产力的发展水平、学校经济条件,很多教师只能在教室里按照传统的模式进行教学,教学手段单一,教学过程枯燥、乏味,造成学生学习物理的兴趣不高。爱因斯坦说:“兴趣是最好的老师。”学习兴趣是推动学生学 “Complex algebra, geometry is difficult, the physical hard on the sky” vividly illustrates the students in physical learning difficulties. The main reason is: physics belongs to a natural discipline, textbooks and more people in the past, production, life and scientific research gradually accumulated. For students, it is purely indirect knowledge, of which many are very abstract and difficult to understand and accept by students. At the same time, under the current teaching conditions and equipment limitations, demonstration experiments and students’ experiments are hard to find. In the past physics teaching, limited to the level of development of productive forces, school economic conditions, many teachers can only teach in the classroom according to the traditional model, a single teaching method, the teaching process is boring, boring, causing students to learn physics interest not tall. Einstein said: “Interest is the best teacher.” Learning interest is to promote student learning
