实验教学在培养学生的观察能力和操作技能等方面具有非常重要的作用,因此,要搞好物理教学必须重视实验教学。那么实验教学在中学物理教学中有哪些作用呢?一、激发学生学习兴趣,丰富学生的感性认识初中学生生活感知范围小,在许多物理知识的学习中缺乏实践经验,头脑中的原认知结构薄弱,特别对一些抽象的概念、规律的接受和理解感到困难,这就要求老师在课堂教学中必须通过实验来加以补偿。通过实验可重现前人所发现的物理现象,创设物理情境,让学生产生身临其境的直感,使学生亲自获得具体的直接经验,得到足够的鲜明而真实的感性材料,为新知识地学习在原认知结构中建立起坚实的感知基础。例如,比热容的概念,是从比较不同质量的同种物质升 Experimental teaching plays an important role in cultivating students’ observation ability and operation skills. Therefore, to improve physics teaching, experimental teaching must be emphasized. What is the role of experimental teaching in secondary school physics teaching? First, to stimulate students ’interest in learning and enrich students’ perceptual awareness Junior high school students have a small range of life perception, lack of practical experience in many physical knowledge learning, the original cognitive structure in mind Weakness, especially for some abstract concepts, laws and acceptance and understanding difficult, which requires teachers in classroom teaching must be experimentally to be compensated. Through experiments, we can reproduce the physical phenomena discovered by our predecessors and create a physical situation so that students can have a direct sense of immersiveness, so that students can obtain specific and direct experiences in person and get enough vivid and authentic sensuous materials for new knowledge Learning builds a solid foundation of perception in the original cognitive structure. For example, the concept of specific heat capacity is from the same quality of different substances rise
