在化学教学中培养学生的认知策略

Cultivation of the Students;Cognition Strategy in the Teaching of Chemistry

培养认知策略促进学生较快适应高职教育,成为学会学习的人。在化学教学中遵循学科结构的逻辑性发展认知结构并对认知结构不断优化,采取一系列教学方法完善学生认知策略,最后“用非随机分派一组控制前、后测实验”进行教育准实验,观察效果:实验班认知策略水平高,学习成绩特别是及格率提高明显。

Students should be cultivated to know the cognition strategy to quickly get used to the higher professional education,and then to become people who know how to study.Cognition structure is developed and optimized in the teaching of chemistry with the logic of discipline Structure.Different teaching approaches are used to improve the students＇ cognition strateg, and an experiment is made with two classes of students chosen at random to compare their performances before and after the cultivation. The class under the cultivation shows a higher level of cognition strategy,with a salient improvement of the record in their studies and of the percentage of pass.
