摘要
采用元分析方法对国内外25项“化学键”主题建构式教学研究的实验结果进行定量、系统分析。结果表明与传统教学相比,促进“化学键”概念理解的建构式教学整体效果显著;班级规模、教学时长和地理位置都对“化学键”建构式教学效果有显著正向影响,长期使用建构式教学的中小规模班级,“化学键”主题教学效果愈明显。基于此提出促进“化学键”概念理解教学和研究的3点建议。
A meta-analysis method was used to analyze the experimental results of 25 constructive teaching studies quantitatively and systematically on the theme of"chemical bonds"at home and abroad.The results showed that compared with traditional teaching,the overall effect of constructive teaching in promoting the understanding of the concept of"chemical bonds"was significant.Class capacity,teaching time and geographical location had a significant positive impact on the effect of"chemical bonds"constructive teaching,and the more obvious the teaching effect of"chemical bonds"in small and medium-sized classes that had been using constructive teaching for a long time.Based on this,three suggestions for promoting the understanding of"chemical bonds"in teaching and research were proposed.
