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.
- Evaluation scale,
- Performance evaluation,
- Experimental operation skills
