据粗略统计,在初中物理两册课本里,共编入354道必学知识的练习题,其中有79题是附有插图的(内含引用课文里的插图),再加上有22道绘图、填图练习题,合计占总题量的28.5％。除习题里有插图,课文里插图更多,“图文并茂”是各科教材建设的共同点之一。它是1993年使用的《九年义务教育初级中学物理课本》的显著特色之一。所以,改革习题插图教学的试验研究既有实用价值还具有普遍意义和广阔的前景的。一、基本作法 1.观察插图全貌,挖掘原题内涵组织学生观察插图,寻找其提供的隐含条件,探究它们之间的内在联系,用以挖掘原题内涵,是改革
According to rough statistics, in the two textbooks for junior high school physics, a total of 354 practice questions must be learned, of which 79 questions are illustrated (including quoted texts), plus 22 plots. , mapping practice exercises, together accounted for 28.5% of the total volume. In addition to illustrations in the exercises, there are more illustrations in the texts. “Pictures and texts” is one of the common points in the construction of textbooks of various subjects. It is one of the distinctive features of the “Nine-Year Compulsory Education Secondary School Physics Textbook” used in 1993. Therefore, the experimental study of reform exercise illustrations has both practical value and universal significance and broad prospects. First, the basic approach 1. Observe the entire picture, excavate the original connotation organize students to observe the illustrations, looking for the implied conditions provided by them, to explore the intrinsic links between them, to dig the original content, reform
