兴趣是最好的老师,是求知的动力,是学生学习主动性和积极性的源泉。初中物理是物理知识的入门和启蒙,是培养学生学习兴趣,具备初步观察事物、分析问题与解决问题能力的关键。因而在初中物理教学中培养学生的兴趣,调动其学习积极性,为今后深造打下良好基础有着不可忽略的作用。而兴趣的最佳激发时间是第一课,本文结合苏科版《引言》谈兴趣的有效激发,促使学生学习的进步。《引言》部分的真正目的就在于激发学生的兴趣,引导学生养成科学的物理学习方法,初步了解科学探究是研究物理问题的主要途径,并逐渐养成 Interest is the best teacher, is the driving force for knowledge, is a source of student learning initiative and enthusiasm. Physics of junior middle school is the introduction and enlightenment of physics knowledge. It is the key to cultivate students’ interest in learning, have the ability to observe things first, analyze problems and solve problems. Therefore, in junior high school physics teaching to cultivate students’ interest, to mobilize their enthusiasm for learning, lay a good foundation for further study has a non-negligible role. The best time to stimulate the interest is the first lesson, this article with the Suke version of “Introduction” talk about the effective excitation of interest, to promote student learning progress. The real purpose of the introduction is to stimulate students’ interest and guide students to develop a scientific method of physical learning. The preliminary understanding of scientific inquiry is the main way to study physical problems and gradually develop
