摘要：

针对以往基础化学实验以终结性评价为主的评价体系存在的弊端，提出评价量表与在线平台相结合的方式对学生的操作过程进行表现性评价。通过传统教学班与实验研究班的对比教学实践，发现学生根据评价量表反馈的结果提升了自身学习能力，降低了操作出错率，从而明显提高了学习效果。因此，评价量表用于实验课的操作评价强化了教学目标，这种评价方式更有利于学生实验操作技能的训练与提高。

关键词: 评价量表, 表现性评价, 实验操作技能

Abstract:

In this work, in view of the disadvantages of the previous assessment system based on summative evaluation of basic chemical experiments, an evaluation scale is proposed to evaluate the students' operation process in combination with an online platform. A comparative practice study of a traditional teaching class and an experimental teaching class reveals that the students' learning ability is improved and that the operation error rate is reduced according to the students' feedback results on the evaluation scale. Thus, the learning effect of students is significantly improved. Therefore, the use of the evaluation scale to evaluate operations in experimental course helps formulate the teaching objectives, which is conducive to the training of students and improvement of their experimental skills.

Key words: Evaluation scale, Performance evaluation, Experimental operation skills
