在化学教学中,常有学生反映:元素符号、化学式等化学用语,元素及其化合物的基本知识,化学基本理论及其计算、实验等,太多太难记,记住后也容易忘记。怎样帮助学生提高记忆效率呢?本人以为主要可以从两个方面着手:一、改进教学方法,提高记忆效果1.加强实验教学,以各种奇异的化学现象吸引学生的注意力,激发学生的学习兴趣,增强记忆如讲授“自燃”这一内容时,开始就演示实验,把白磷溶液滴在滤纸上,一会儿滤纸就自己燃烧起来。这时提出问题,滤纸为什么自行燃烧?这个实验及这个问题,集中了学生的注意力,激发了
In chemistry teaching, students often reflect: chemical symbols such as elemental symbols, chemical formulas such as chemical formulas, basic knowledge of elements and their compounds, basic chemical theories and calculations, experiments, etc. Too many are too hard to remember and easy to forget after remembering. How to help students improve memory efficiency? I think the main two aspects to proceed: First, to improve teaching methods, improve memory effect 1. Strengthen the experimental teaching, with a variety of strange chemical phenomena to attract students ’attention and stimulate students’ learning Interest, enhance memory, such as teaching “spontaneous combustion ” this content, began to demonstrate experiments, the white phosphorus solution drops on the filter paper, while the filter paper on their own burning up. At this time ask questions, why did the paper burn itself? This experiment and this question have focused the students’ attention and inspired
