几年来,学生经常反映元素的单质和化合物知识,内容细碎、头绪较多、缺少规律性,不好复习、不好记忆;特别到毕业总复习时,学生的复习内容增加,对这类已学过的知识不感兴趣,往往出现厌学情绪。为了解决这些问题、经过试验和研究,决定采用“系列实验”的复习方法,以加深学生对单质和化合物知识的再感知。取得了很好的复习效果。 Over the past few years, students often reflect the elemental and compound knowledge of the elements. They are crushing, clueless, lacking in regularity, and difficult to review and remember. When students review in the final year of graduation, the review content of students increases. Excessive knowledge is not interested, and it often appears that they are tired of learning. In order to solve these problems, through experiments and research, it was decided to use the “series of experiments” review method to deepen students’ re-perception of single substance and compound knowledge. Has achieved a good review effect.
