物理是以观察和实验作为基础的学科,物理知识多来源于生活实践,实践对物理的发展具有推动作用。由于各种条件的限制,初中的物理课堂上传授的知识概念过于抽象,无法吸引学生的学习兴趣。在教学过程中,运用趣味实验,不仅能将枯燥难懂的知识简单化,而且能激发学生的学习热情,引发学生的思考,提升课堂效率。一、运用趣味实验激发学习兴趣在探究影响导体电阻大小的因素时,老师在课前提出问题:“打火机能否点亮灯泡?”引发学生的思考讨论后演示实验,
Physics is based on observation and experiment as the basis of disciplines. Most of the physical knowledge comes from the practice of life, and practice has a promoting effect on the development of physics. Due to various conditions, the concept of knowledge taught in junior high school physics classroom is too abstract to attract students’ interest in learning. In the teaching process, the use of fun experiments, not only can simplify the knowledge of boring and difficult, but also stimulate students ’enthusiasm for learning, trigger students’ thinking and improve classroom efficiency. First, the use of fun experiments to stimulate interest in learning In exploring the factors that affect the size of the conductor resistance, the teacher asked questions before the class: “Lighter can light bulb? ” Initiation of students to discuss After discussion demonstration experiment,
