摘要
目前初中科学复习课课堂上普遍存在着没有教学目标,缺乏重点、难点的突破,平均使力或以练习来代替复习,机械地重复,缺乏新意等急待解决的老问题.基于“学习进阶”理论,以中考“科学图像解读”复习课为例,依据学生思维的三段式进阶发展,创设学生最近发展区--动车行驶的距离与时间图像,构建一个循序渐进的合理展示顺序-质量与体积关系,帮助学生建构中考科学图像解读的核心概念完整体系-正比例函数关系及图像,强化学生的渗透意识-力与距离及电压与电流的图像,增强初中学生的综合素质,培养其良好的科学素养.
The current class junior high school sci-ence review class generally has^no teaching objectives, lack of focus, difficulty and breakthrough of the average force or in practice instead of the review,mechanical repetition, lack of new ideas and old problems.Based on the theory of “ learning”,“ scientificimageinterpreta- tion” in senior high school entrance examination review class as an example, on the basis of the three section type students thinking of advanced development, cre- ation of distance and time images of their recent devel-opment area-motor car driving, build a reasonable order of step by step voltage and power flow:the core concept of complete system-help the students to construct scien-tific interpretation of images is the proportion of senior high school entrance examination function and image: strengthen students^ awareness of the infiltration-quali-ty and volume as well as the image force and distance: enhance the comprehensive quality of junior high school students:cultivate their good scientific literacy.
