在初中化学课堂教学的调研中,常常发现,学生动手实验的能力比较弱。习惯也好,操作也好,总让人觉得离我们的要求有不小的差距。于是,笔者想到了一个话题:课堂尚且如此,课外实验又究竟完成得怎样呢?一、现状调查笔者于近期作了一次调查(问卷和座谈)。罗列了初中化学课本课外实验共计八个,对农村初中四个辅导区九所初中646名初三学生作了问卷调查。其中一个实验也没有完成的占28.2%,完成1-2个实验的占42.2%,完成3-4个实验的占21.3%,完成5个以上但未全部完成的占8.1%,全部完成的占0%。【调查结论】:1.近30%的同学一个课外实验也没有完成。2.全部完成实验的人数为零。
In junior high school chemistry classroom teaching research, often found that students ability to experiment is relatively weak. Good habits, operations Ye Hao, people always feel that there is a big gap between our requirements. So, I thought of a topic: the classroom so, the extra-curricular experiment and how exactly completed? First, the status quo survey I recently made a survey (questionnaires and discussion). A total of eight junior high school chemistry textbooks were included in the extracurricular experiments, and 646 junior high school students in nine junior middle schools in four junior high schools were surveyed. 28.2% did not complete one experiment, 42.2% completed 1-2 experiments, 21.3% completed 3-4 experiments, and completed more than 5 but did not complete 8.1%, all completed 0%. [Conclusions]: 1. Nearly 30% of the students did not complete an extra-curricular experiment. 2. The number of completed experiments is zero.
