关于提高初中化学教学有效性的研究

Research on Improvement of the Effectiveness in Junior Middle School Chemistry Teaching

有效教学是指在有限的40分钟或者45分钟课堂时间内,在教师的精心设计和组织教学下,学生所取得的最佳学习效果。在化学课堂教学中,要想达到高效,需从四个方面入手:一是教师转变教学理念,课堂教学以学生为本;二是加强化学实验,组织好学生实验;三是树立创新意识,培养创新思维;四是充分运用多媒体技术,实现化学课堂与信息技术的整合。

Effective teaching means the best learning effect that students can get under the teaching well designed and organized by teachers within a limited class time of 40 minutes or 45 minutes. For high efficiency in chemistry classes,the following four aspects should be carried out：firstly,changing teachers＇ teaching ideas and building a student-oriented classroom;secondly,strengthening and organizing students＇ chemical experiment;thirdly,establishing innovation consciousness and cultivating innovative thinking;fourthly,making full use of multimedia technology to implement the integration of chemical classroom and information technology.
