Construction And Application Of Experimental Safety Micro-learning System For College Students

This paper summarizes the research status of laboratory safety education at home and abroad.Based on modern learning theory and mobile learning methods,a Micro-learning system for experimental safety of college students is constructed by using We chat Public Signal.The Micro-learning of safety experiment knowledge in a university has solved the problem of ubiquitous learning of College Students 'experimental safety knowledge,which has certain theoretical significance and practical value.In this paper,a questionnaire is used to investigate the safety information of chemistry experiment of a university student,and We Chat official account micro-learning is used in this paper.According to the content of "Experimental Safety Education" in a college of chemical materials,the map of experimental safety knowledge,the task list of experimental safety learning and the micro-course of experimental safety were constructed.The function structure of the micro-learning system is designed,which adapts the micro-course resources to the main functional modules of micro-learning,and publishes it through the experimental security We Chat official account.According to the requirements of experimental safety education and micro-learning,a scale for evaluation of laboratory safety and micro-learning activities was designed.Selected chemical material freshmen to carry out experimental safety micro-learning activities.In the experiment safety micro-learning activity,through the experiment safety We Chat official account to obtain the academic situation data,the questionnaire investigation experiment safety micro-learning system satisfaction and the experiment safety skill operation and so on data,etc.The data of questionnaire and the results of safety knowledge assessmentare statistically analyzed.About 73.53% of college students have mastered the safety knowledge of chemical experiment,and the safety knowledge of chemical experiment has been mastered by 73.53% of college students.The results show that most of the students have a good grasp of experimental safety knowledge and are satisfied with the interface of micro-learning system and the content of experimental safety knowledge.There is still a need to strengthen training in the operation of experimental safety skills.Most students say that when they encounter safety doubts in the chemical experiment,they can turn to the laboratory safety micro-learning system in time to solve the safety problems in the experiment.
