本人经调查得知,中学化学教师中80%的人认为学生实验课难上,理由是需要指导的学生多,组织教学难度大,教学时间不易控制。查看各种重要考试的统计结果发现,实验题往往是学生的弱项,如我市2001年中考化学科,全市得分率最低的就是实验题,人均得分率只有35%,远远低于其余题的得分率 I learned from investigations that 80% of middle school chemistry teachers believe that students’ experimental classes are difficult. The reason is that there are many students who need guidance, it is difficult to organize teaching, and teaching time is not easy to control. Looking at the statistical results of various important examinations, it is found that the experiment questions are often the weaknesses of students. For example, in 2001, the city’s entrance examination chemistry department, the city’s lowest scoring rate is the experimental problem, the average per capita scoring rate is only 35%, far lower than the remaining questions.
