一、前言我们化学教学组,由于认识到化学是一门以实验为根据的科学,因此,在现有的条件下,对教学大纲中所规定的演示或学生实验,一般的都完成了。但是,学生还存在着,老师怎么讲就怎么作,和只注意化学变化的现象;不重视操作技能的提高和分析现象的本质等问题。我们为了要加强劳动教育,培养学生的独立实验操作技能,贯彻理论和实际相联系的原则,便决定加强实验课。我们也研究了一些办法,例如利用实验进行提问和巩固,做课前实验或留实验作业等。同时,也决定了用实验进行测验。在制订学期教学计划时增加了实验测验课。现在将一年来试行结果,以高三的一次测验为例写出,供大家研究参考。二、进行的经过 (1)计划:高三有机化学在教学计划中分四个单元,即烃、烃的衍生物、醣及含氮有机物。我们计划在第二、三、四单元讲完后,各举行一次实验
I. INTRODUCTION Since our understanding of chemistry as a science based on experimentation, our chemistry teaching team has generally completed the demonstration or student experiments prescribed in the syllabus under the current conditions. However, there are still some problems that the students still have about how teachers should behave and only pay attention to the change of chemistry. They do not attach importance to the improvement of operational skills and the nature of the phenomenon. In order to strengthen our labor education, train our students in their independent experimental skills, and implement the principle of linking theory with practice, we decided to strengthen the experimental class. We have also explored ways to use questions such as experimenting with questions and consolidations, doing pre-school experiments or leaving experimental work. At the same time, also decided to experiment with the test. In the development of semester teaching plan to increase the experimental test class. Now a year pilot results, a high school year test as an example to write, for your research and reference. Second, the progress (1) plan: Senior Secondary Organic Chemistry in the teaching plan is divided into four units, namely hydrocarbons, hydrocarbon derivatives, sugars and nitrogenous organic matter. We plan to hold experiments once the second, third and fourth units are finished
