学生掌握最基础的化学知识,需要通过记忆。牢记所学的知识,是掌握知识的标量之一,同时也是掌握知识和技能的必要条件。初中化学教材,描述性的材料多,变化也较复杂,与数学、物理相比,要求记忆的内容较多,学生记忆负担很重。有为数不少的初中学生感觉化学概念多、理论玄、实验杂、计算难,可谓难记又易忘。这些学生视学化学为畏途,他们对这一学科不仅不能顺利入门,而且刚一
Students master the most basic chemical knowledge, need to pass memory. Keeping in mind what you have learned is one of the scalar masters of knowledge and a necessary condition for mastery of knowledge and skills. Junior high school chemistry textbooks, descriptive materials, changes are more complex, compared with mathematics, physics, require more memory, students have a heavy memory burden. There are a large number of junior high school students feel more chemical concepts, theoretical mystery, experimental miscellaneous, difficult to calculate, can be described as hard to remember and easy to forget. These students learn chemistry for fear, they not only can not successfully get started in this discipline, but just one
