当前,中学化学教学面临着两个基本情况:一个是十年动乱造成的学生知识水平的下降,知识面狭窄且有“夹生”现象,另一个是吸收国外经验,教材内容层层下放,份量和难度有所增加。这两个基本情况集中突出了一个矛盾——低程度与高要求。从现在新入学的大学生来看,他们当中相当一部分人是属于高分低能的,思维的敏捷性和严密性都较差,视野狭窄,对五光十色,丰富多彩的物质世界,不仅缺乏必要的理性知识,甚至连一般的感性知识也十分有限。面对这样的现实,传统的教学思想,教学步骤和教学方法,如果不作较大的改变,势必影响教学任务的完成,更谈不到能力的培养。
At present, chemistry teaching in middle schools is faced with two basic situations: one is the decline of students’ knowledge level caused by ten years of turmoil, narrow knowledge and “caught students” phenomenon, and the other is the absorption of foreign experience, teaching materials are decentralized, and the amount of The difficulty has increased. These two basic situations highlight a contradiction - low level and high demand. Judging from the new college students who are currently enrolled, a considerable number of them are high scores and low energy. They have poor agility and rigor in thinking, and they have a narrow field of vision. They not only lack the necessary rational knowledge, but also have a colorful and colorful material world. Even the general emotional knowledge is very limited. Faced with this reality, traditional teaching ideas, teaching procedures and teaching methods, if not made major changes, will inevitably affect the completion of teaching tasks, and even less talk about ability training.
