| 摘 要： | 通过对化学概念关键期研究进行调查与分析,发现学生学习化学概念存在着前概念的影响;认为初三是学习化学概念的启蒙期,初三到高一为化学概念的衔接期,高一为化学概念入门关键期,高二为化学概念低潮期,高三为化学概念的系统化结构化的升华期。把握化学概念各关键期教学的特点和规律,有助于收到事半功倍的教学效果。

| Abstract: | The investigation and the analysis on critical period of chemistry concept teaching shows that the students who learn the chemistry concepts are affected by the preceding concepts. And the critical period of chem- istry concepts can be divided into several stages. Grade Three in junior high schools is the beginning of chemistry concepts learning. The period from Grade Three in junior high schools to Grade One in senior high schools is the period of transition. Grade One in senior high schools is a key period to start to learn chemistry concepts. Grade Two in senior high schools is a downturn period. Grade Three in senior high schools is a sublimation period of systemati- zation and Strueturalization of chemistry concepts. Different periods have their own characteristics and laws of teach- ing. Teaching according to the characteristics and the laws will get twofold results with half the effort. |
