因为在中学化学教学过程当中,实验课所占的份额较少,考试较为简单,学习压力不大,所以职高学生更容易对化学实验掉以轻心、不重视,学生精神分散,就会影响化学实验的教学效果。正因为如此,作为老师,更要对学生的化学实验进行周密的管理,对学生的化学实验成绩进行科学合理的评定。学生的化学实验总成绩由平时成绩(占70%)和考试成绩(占30%)两块组成,而平时成绩由预习成绩(占10%),实验操作及违纪情况(占15%)、实验报告(占45%)组成,考试成绩由笔试(占10%)及操作(占20%)构成。
Because in the middle school chemistry teaching process, the experimental class account for a small share of the examination is relatively simple, little learning pressure, so vocational students more easily chemical experiments lightly, do not pay attention to the spirit of student fragmentation, it will affect the chemistry experiment teaching effect. Because of this, as a teacher, students should be more careful chemical experiments, chemical test results of students a scientific and reasonable assessment. The students’ total score of chemistry experiment consists of two grades: normal grade (70%) and test grade (30%), while the average grades consist of preview grade (10%), experimental operation and discipline violation Report (45%), test scores by the written examination (10%) and operation (20%) form.
