1994年我县高二学生参加理、化、生实验考查,在解答物理试题“测定金属的电阻率”时,笔者抽查了27名学生,他们中除个别学生需教师指导才能做完外,多数学生能独立完成实验,但是,还存在实验操作不够熟练、不够规范,对知识不能运用自如等问题。在实验的技能技巧方面和养成良好的实验习惯方面,还有待我们在今后的教学中改进和加强。现就抽查中发现的一些问题,综述如下:
In 1994, my senior high school student from the county participated in the physical, chemical, and biological experiments. When answering the physics test “Measurement of Resistivity of Metals”, the author sampled 27 students, except for a few students who required teacher guidance to complete. Can complete the experiment independently, however, there are still problems such as the lack of proficiency in the experiment operation, lack of standardization, and the inability to use knowledge freely. In the aspect of experimental skills and development of good experimental habits, we still need to improve and strengthen our teaching in the future. Some of the problems found in spot checks are summarized as follows:
