本学年,在学校领导和同科组老师的热情鼓励与支持下,我运用自学辅导法在高二化学教学中作了一些尝试,取得一定效果。下面以《络合物》这节难点课为例,谈谈我是如何运用此法进行教学尝试的。 课时:两课时 教学过程: 第一课时 一、课前布置预习: 为了让学生在上课时能创造有利的心理状态,打好注意定向的基础,教师先布置预习P77～P80第二段,并要求学生围绕如下预习思考题写出笔记。 预习思考题:(写在小黑板,挂出) (1)Cu(OH)_2沉淀溶于浓氨水吗?为什么?试用平衡移动的观点解释。 (2)什么叫络离子?什么叫络合物?
This school year, with the warm encouragement and support of the school leaders and teachers of the same subjects, I made some attempts in chemistry teaching in the second year using self-study counseling methods and achieved some results. Here to “complex” this difficulty class as an example, to talk about how I use this method of teaching to try. Class hours: Two hours of teaching process: The first class hours First, the pre-class layout preview: In order to allow students to create a favorable psychological state in class, lay a good foundation for orientation, the teacher first preview P77 ~ P80 second paragraph, and asked Students write notes around the following preview questions. Pre-thinking questions: (written on the blackboard, hang out) (1) Cu (OH) _2 precipitate dissolved in concentrated ammonia? Why? Try to balance the movement point of view. (2) What is complex ion? What is complex?
