多媒体技术的发展对化学这门以实验为基础的学科影响极其深远,而多媒体技术的运用使化学课堂更有利于学生形象思维的发展和学习主动性的提高。因此,主要围绕多媒体课堂教学的有效性这一问题,通过对高中化学课堂的典型案例进行分析,找到理论和实践的结合点,总结经验,引发大家对多媒体技术与高中化学课堂教学结合的进一步思考。 The development of multimedia technology has a far-reaching influence on the chemistry-based experiment-based discipline. The use of multimedia technology makes the chemistry class more conducive to the development of students’ image thinking and the improvement of learning initiative. Therefore, the main focus on the issue of the effectiveness of multimedia classroom teaching, through the analysis of typical cases of high school chemistry class to find the combination of theory and practice, sum up experience, triggering further thinking of multimedia technology and high school chemistry classroom teaching .
