| 摘 要： | 本教学设计在建构主义思想的指导下,结合探究式教学的特点,对"机械能守恒定律"这一节进行教学设计。首先,教师创设情境引出机械能,其次,通过单摆对照演示实验引导学生发现机械能可以守恒,通过理论探究引导学生推导机械能守恒定律以及机械能守恒条件,通过实验探究验证机械能守恒定律,最后,通过例题分析,引导学生深入理解、应用机械能守恒定律,完成对新知识的意义建构,并在此过程中提高学生的探究、应用能力。

| Abstract: | Under the guidance of constructivism and combining with the characteristics of inquiry teaching, we conduct the teaching design of the section "law of conservation of mechanical energy". First, the teacher creates a situation to elicit mechanical energy, then, the students are guided to find that mechanical energy can be conserved by comparing the experiments with single pendulum. Through theoretical exploration,students are guided to deduce the law of conservation of mechanical energy and the conservation conditions of mechanical energy. Through experiments, students can verify the conservation law of mechanical energy. Finally, through the analysis of examples, students are guided to deeply understand and apply the law of conservation of mechanical energy, to complete the meaning construction of new knowledge, and the students’ exploration and application ability is improved in this process. |
