A Study On The Effect Of Virtual Experiment Reversal Classroom On Students’ Experimental Operation Ability

In the context of educational modernization,In the age of information technology,the demand for educational talents is more comprehensive and diversified,the ability of experimental inquiry,self-awareness of inquiry and experimental operation are required more strictly.However,due to the limitation of teaching time or the difficulty in carrying out experiments,the students’ needs for chemical experiments can not be met,and the talents trained by the school lack the ability of experiment operation.This study aims at the problem that some schools seldom take students to the chemical laboratory because of the limited teaching hours and the complicated and dangerous experimental operation,which results in the lack of students’ experimental operation ability,by using the methods of literature analysis,experiment,interview and observation,according to the concept of virtual simulation experiment,reversal of classroom and experimental operation ability,based on the micro-learning,knowledge construction and mastery of the theoretical basis of learning,the teaching design model was constructed and a control experiment was carried out in the third grade of the experimental school,to analyze and evaluate students’ experimental operation ability from four dimensions:mastery of experimental equipment,standard of experimental operation,handling of unexpected situation and restoration of experimental environment,this paper discusses the influence of virtual experiment reversal classroom teaching mode on students’ operation ability of chemical experiment,and provides teaching ideas for improving students’ operation ability of experiment.The results show that the teaching mode of virtual experiment reversal class can improve students’ experimental operation ability,and it has the most obvious effect on the dimension of students’ experimental operation standard,the effect of this teaching mode on the speed of experimental operation is the most obvious,but the effect on the students’ experimental innovation ability is not obvious In teaching,teachers should pay attention to the principle of combining virtual experiment with real experiment and flipping classroom with traditional classroom,and use the teaching model of flipping classroom appropriately and reasonably.
