化学教学大纲指出:教师应特别注意对学生知识的考核和成绩的正确评定。因此,我们考核化学教学工作时,不仅要从形式上,而更重要的是要从实质上去考核。要从工作实质上进行考核,就必须根据考核教学工作质量的标准,因为只有质量的标准才能使我们正确地判断我们在教学工作中所用的各种方式、方法的实际效果。 The chemistry syllabus states: Teachers should pay special attention to the assessment of students’ knowledge and the correct assessment of grades. Therefore, when examining the teaching of chemistry, we should evaluate not only from the formal but also, more importantly, the substantive assessment. To conduct the assessment in essence from the work, we must base ourselves on the standards for the quality of the teaching work, because only the quality standards can enable us to correctly judge the actual effects of the various methods and methods we use in the teaching work.
