在研究《食物链和食物网》一课时,我本着走进去深钻教材,走出来活用教材的想法,对我市前后使用过的三套教材进行了认真学习和分析。通过学习,我发现现行教材的呈现方式比较浅显,缺乏深度,探究活动也过于单薄,该指点的都指点了,该告诉的也都写清楚了,不利于学生的自主探究。感觉到无多少内容可上,教学活动难于突破和创新。 In the study of “Food Chain and Food Network” a class, I walked in deeply drill textbooks, out of the idea of ​​using teaching materials, the city before and after the three sets of teaching materials used for serious study and analysis. Through the study, I found that the current textbook presentation method is relatively shallow, lack of depth, inquiry activities are too thin, the pointing are pointing, the tell are also written clearly, is not conducive to students’ autonomous inquiry. Feel no more content can be difficult to break through and teaching innovation.
