Student experiment comprehensive evaluation method based on online laboratory

Abstract

The invention discloses a student experiment comprehensive evaluation method based on an online laboratory, belonging to the field of student experiment evaluation. Firstly, the experiment course of a student and the online laboratory are set. After the student carries out an experiment through the online laboratory, the student submits an experiment report with experiment process key step screenshot information. An experiment teacher can extract the information of the student experiment from a server database, and the information comprises the record of a student registration account, the time of entering a system to carry out the experiment, experiment time, experiment configuration, and an upload algorithm. Combined with the information extracted from the database, through the analysis of the screenshot in the experiment report and the experiment report, the experiment of the student is finally judged comprehensively, and an objective experiment evaluation result is given. According to the method, multiple standards are simultaneously used to evaluate the experiment of the student, through the comprehensive analysis, the experiment evaluation result is finally obtained, and the participation of the student experiment and the objectivity of experimental evaluation are ensured.

Description

technical field [0001] The invention belongs to the technical field of student experiment evaluation, in particular to an online laboratory-based comprehensive evaluation method for student experiments. Background technique [0002] Experimental courses are an indispensable part of engineering disciplines and an important link for students to exercise their hands-on ability and consolidate theoretical knowledge. Therefore, the evaluation of students' experimental work is particularly critical. The traditional experimental method is to use the instruments and equipment in the laboratory to conduct experiments, and students need to go to the experiment regularly and at fixed points to conduct experiments. If there are many students, there may be a queue. At the same time, it is impossible for the experimental teacher to supervise everyone. Finally, the evaluation method of the experimental work is that the students submit the experimental report, and the teacher evaluates t...

AI Technical Summary

Problems solved by technology

This method of evaluating experimental work by relying solely on written materials is not only single and subjective, but also cannot guarantee students' participation in the experiment without supervision

In addition, the lab report is written and handed in outside the classroom, so it is difficult to find and avoid plagiarism in the lab report

Because even if several identical lab reports are found, the teacher cannot tell which one is the original report

These are not conducive to the development of experimental teaching work, and the expected experimental results cannot be achieved.
