【摘要】：初中化学中涉及到许多化学概念、化学原理、化学实验、化学计算等许多内容,使学生在学习时虽然明白理解,但是过后其认识就会模糊不清,甚至遗忘。面对繁重的学习任务、零散繁杂的化学知识,许多学生很难理清化学知识间的线索以及它们之间的内在联系,迁移能力、概括归纳能力差。初中化学中酸碱盐的学习,对于初中生来说是学习的难点也是重点,知识点较多而且比较零散不易记忆,使用思维导图作为一种教学策略运用到酸碱盐的教学中,可以把零乱的信息组成信息块,了解其之间的联系,便于记忆。本研究利用思维导图,着手于初中化学教学“初识酸和碱”单元教学,在新授课和复习课中将思维导图作为一种学习工具运用于教学中,经过一段时间的实验后分别对实验班和对照班进行测试比较,结合学生使用思维导图的情况,最终得出的结果表明思维导图的运用有利于提高化学学习效果,从而证明思维导图是一种适合于初中学生的化学学习策略,也有利于学生思维的拓展和学习能力的提高。
[Abstract]:Junior middle school chemistry involves many chemical concepts, chemical principles, chemical experiments, chemical calculations, and so on, so that students in the study although understand clearly, but later their understanding will be blurred, or even forgotten. In the face of heavy learning tasks and scattered and complicated chemical knowledge, many students are difficult to sort out the clues between chemical knowledge and their internal relations, transfer ability and poor generalization ability. The study of acid, alkali and salt in junior high school chemistry is a difficult and important point for junior high school students. It has more knowledge and is not easy to remember in a scattered way. Therefore, thinking map is used as a teaching strategy in the teaching of acid, base and salt. Information can be fragmented into blocks of information, to understand the relationship between them, easy to remember. In this study, thinking map was used in the unit teaching of "initial acid and alkali" in junior high school chemistry teaching. In the new teaching and reviewing class, the thinking map was used as a learning tool in the teaching. After a period of experiment, the experimental class and the control class were tested and compared, and the result showed that the use of the thinking map was helpful to improve the effect of chemistry learning. Thus, it is proved that thinking mapping is a kind of chemistry learning strategy suitable for junior middle school students, and it is also beneficial to the expansion of students' thinking and the improvement of their learning ability.
