随着现代科学技术的飞速发展,多媒体技术已进入高中化学的课堂教学之中,化学是一门以实验为基础的自然学科。它不但强调理论知识的学习,更注重实验能力的培养。而多媒体可以化静为动,化虚为实,化抽象为直观;同时,用多媒体辅助教学,能创设逼真的教学环境、动静结合的教学图象、生动活泼的教学气氛,充分调动学生的积极性;尤其是化学课堂的教学中,学生是主体,教师起主导作用,而各种媒体则只能起辅助教学作用。在一节课的教学中,恰如其分地使用多媒体技术辅助教学,会给教学带来事半功倍的教学效果。相反,不切实际的滥用多媒体,会严重影响实际的教学效果的落实。一、借助多媒体强化课前研究,激发学习兴趣
With the rapid development of modern science and technology, multimedia technology has entered the high school chemistry classroom teaching, chemistry is a natural science based on experiments. It not only emphasizes the study of theoretical knowledge, but also focuses on the cultivation of experimental ability. At the same time, multimedia-assisted teaching can create a realistic teaching environment, a combination of static and dynamic teaching images, a vivid and lively teaching atmosphere, and fully mobilize students’ enthusiasm In particular, in the teaching of chemistry class, students are the main body and teachers play a leading role. However, all kinds of media can only play an auxiliary teaching role. In a class of teaching, proper use of multimedia technology to assist teaching, will give teaching a multiplier effect. On the contrary, the unrealistic abuse of multimedia will seriously affect the implementation of the actual teaching effect. First, with multimedia to enhance pre-class research, stimulate interest in learning
