视听引导是一种别开生面的教学方法,对课堂教学实效性的提升往往能起到意想不到的作用。基于上述背景,本文将研究切入点放在“视频教学在初中生物课堂中的应用”上,通过理论结合案例的方式,着重论述“创设视听对比情境,引导学生参与动力”、“利用视频巩固趣化,引导学生记忆难点”、“借助视频引入新课,引导构建问题场景”三种具体教学策略,希望为激活初中生物课堂教学提供参考。 Audio-visual guidance is a unique teaching method, which often plays an unexpected role in improving the effectiveness of classroom teaching. Based on the above background, this paper focuses on “application of video teaching in junior high school biology class” and through the combination of theory and case, focusing on “creating audio-visual comparison context and guiding students to participate in motivation” “Use the video to consolidate the fun and guide the students to remember the difficulties ”, “introduce a new lesson with video, guide the construction of the problem scene ” three specific teaching strategies, hoping to provide reference for the activation of junior high school biology classroom teaching.
