物理是一门以观察、实验为基础的学科,所以物理的实验课显得尤为重要。在新课程背景下,如何提高物理实验的教学实效,培养学生的学习兴趣,使学生产生积极学习的欲望,是每一位物理老师任重而道远的目标。在九年级第十六章第四节《变阻器》的一节实验课中,我使用了导学案,改进了教材中的实验步骤,进行了一些尝试。现将本节教学设计思想与大家交流一下。首先在引课上,我采用了可调亮度的台灯这一实物展示,唤起学生的注意,引发学生的思:台灯的亮度如何改变的?从而使学
Physics is a subject that is based on observation and experiment, so the physics experiment class is particularly important. Under the background of the new curriculum, how to improve the teaching effectiveness of physics experiment, cultivate students’ interest in learning and make students desire for active learning are the long-awaited goals of every physics teacher. In the ninth grade, Chapter 16, Section IV, “Rheostats” in an experimental class, I used the guide case, to improve the experimental steps in the textbook, and made some attempts. Now this section teaching design ideas to share with you. First, in the lesson, I used adjustable brightness table lamp this kind of physical display, arouse the attention of students, triggering the student’s thinking: how to change the brightness of the lamp so that the study
