一、多媒体与初中物理课堂有效整合的必要性物理是一门实验科学,它来源于生产、生活,也解决生产、生活中出现的问题,指导人们进行有效的生产,科学的生活。初中物理的学习对象是初中生,由于生理的特点和生活经验阅历的特点,导致初中学生在学习物理时有较大的难度,特别是在光的折射、透镜、压强和浮力、简单机械、功和功率、电功和电功率等较抽象或对学生要求较高的章节中,学生对物理现象、物理概念、物理规律难以理解,形成学习上的障碍,导致学生学习物理的兴趣热情下降,形成缺 I. The Necessity of Effective Integration of Multimedia and Junior Middle School Physics Physics is an experimental science. It comes from production and life, and also solves problems in production and life, and guides people to conduct effective production and scientific life. Junior high school physics students are junior high school students, because of the physiological characteristics and experience of life experience characteristics, resulting in junior high school students in the study of physics more difficult, especially in light refraction, lens, pressure and buoyancy, simple machinery, work And the power, electrical and electrical power, abstraction or higher requirements for students in the chapters, the students of physical phenomena, physical concepts, the laws of physics difficult to understand, the formation of learning obstacles, leading students to study enthusiasm for physical decline in the formation of the lack of
