一、案例背景《实验:探究功与速度变化的关系》是人教版普通高中课程标准实验教科书必修2第七章中的一节内容,安排两课时完成。第一课时,通过师生间的互动、共同探究,结合教师适当演示,主要解决实验的设计思路问题,使学生对实验探究过程有一个初步认识。第二课时,学生动手探究,获取并分析、处理实验数据,得出结论。本案例叙述的就是第二课时中分析、处理实验数据,得出结论的片段。二、案例主题本节内容的教学目标之一是理解实验数据处理时寻找W与v的关系的方法。本节课是让学生对现代信息技术应用于物理研究 First, the background of the case “experiment: to explore the relationship between power and speed changes” is a PEP ordinary high school curriculum standard textbook compulsory 2 Chapter VII of a section, arranged for two classes to complete. The first lesson, through the interaction between teachers and students to explore, combined with the appropriate presentation of teachers, the main solution to the problem of experimental design ideas, so that students have a preliminary understanding of the process of experimental inquiry. The second class, students explore, acquire and analyze, deal with experimental data, draw conclusions. This case is described in the second lesson analysis, processing experimental data, the conclusion of the fragment. Second, the case theme The teaching objectives of this section is to understand the experimental data processing to find the relationship between W and v. This lesson is for students to apply modern information technology to physics research
