一直以来,一线教师都非常清楚,有效是相对于低效和无效而言的,但明确其含义是没有太大意义的,只有真正将有效两个字落实到实际教学中才是价值的体现。初中化学教师要仔细研究化学教参,通过组织多种活动,从多角度入手逐步构建出真正有效的化学课堂,从而使学生在自主探究、合作交流中轻松掌握基本化学知识,同时为课程教学目标的最大限度实现做好保障工作。 For a long time, front-line teachers are very clear and effective in terms of inefficiency and inefficiency. However, it is meaningless to clarify their meaning. Only the actual implementation of the two words into actual teaching is the embodiment of value. Junior high school chemistry teachers should carefully study chemical teaching parameters, through organizing a variety of activities, from a multi-angle to gradually create a real and effective chemistry class, so that students in their own exploration, cooperation and exchange of basic chemistry easily master knowledge, at the same time as the teaching objectives The maximum to achieve good security work.
