论文部分内容阅读
在以往几年,我每教到初中化学第一章第5节和第6节时,就感到为难,因为这部分知识学生总难学好。为改变这种状况,我曾作一个试验,即在讲这部分知识之前,先对学生说:“你们将要学习的两节内容是这一章的难点,也是你们学习化学碰到的第一个难关,如果你们能闯过这一关,以后学好化学就不成问题。我相信你们能过好这一关。”就此,学生在学这两节内容时,倍加认真。以后我在教学中又经常对他们加以激励,学生的学习热情一直很高。以致在单元过关测验中获得了平均94.3分的好成绩,(试题据《初中化学教学目标检测》中的测验题,并有所增加。)这出乎我的意料。因为以往各届学生在作相应测验时,成绩都只有80分左右。这个
In each of the past few years, I felt embarrassed each time I went to Sections 5 and 6 of the first chapter of junior high school chemistry because it was always difficult for some of these students to learn. In order to change this situation, I conducted an experiment in which I first said to the students: “The two sections you will want to learn are the difficult points in this chapter, and the first one you learned about chemistry If you can get through this level, then you should be able to learn chemistry well afterwards, and I believe you can do a good job. ”As a result, students are paying more attention to these two sections. After I often teach them to inspire them, the students enthusiasm for learning has always been high. Which resulted in an average of 94.3 points in the unit clearance test (the test questions have increased according to the test questions in the “Middle School Chemistry Teaching Objectives Test”) This is beyond my expectations. Because in the past each student in the corresponding test, the results are only about 80 minutes. This one
