随着课堂教学手段的不断改进,中学生物学教学不仅使用挂图、标本、模型等常规直观教具,而且采用了教学电影、幻灯、录像投影和计算机等电教媒体,为激发学生学习兴趣和提高课堂教学效率,起到了非常积极的作用。但由此也引起了教学中对黑板画的忽视。笔者在生物学教学实践中除采用上述手段外,还结合教材中有关形态、结构等内容辅以黑板画,取得了良好效果。现就此谈谈粗浅的看法,供同行参考指
With the continuous improvement of classroom teaching methods, biology teaching in middle schools not only uses conventional visual aids such as wall charts, specimens and models, but also uses audio-visual media such as teaching films, slides, video projections, and computers, in order to stimulate students’ interest in learning and improve classroom teaching. Efficiency has played a very positive role. However, it also caused the neglect of blackboard painting in teaching. In addition to using the above methods, the author also combined the relevant forms, structures, etc. in the teaching materials with blackboard paintings and achieved good results. This is a brief discussion on this point for peer reference
