Research On The Effect Of Micro-class Teaching Based On Systematic Evaluation Method

Since the "micro lesson" was proposed in 2011,micro lesson teaching has gradually emerged in the field of education and been widely concerned by educational researchers.The teaching effect of micro-class has become a hot topic in the field of education,and whether micro-class teaching can improve the teaching status has been controversial.In this study,a systematic evaluation method was adopted to conduct meta-analysis on high-quality original studies and statistical analysis on their effect values,so as to summarize the effect of micro-course teaching and the factors that may interfere with the effect of micro-course teaching.This research through the retrieval in January 2009-October 2019 China hownet(CNKI),VIP,ten thousand party,Web of Science,ProQuest,EBSCOhost electronic databases,according to principle of PICOS exclusion criteria,select standard randomized controlled trials,and the quality evaluation of the literature of into,eliminating low quality literature eventually in 83 after the original documents.After relevant data were extracted and classified,Meta analysis was conducted with Review Manager5.3 software.The analysis results showed that micro-course teaching has obvious advantages in improving academic performance,enhancing students' learning ability and practical ability,improving their learning attitude,and enhancing students' satisfaction.Micro lesson positive promoting effect on the teaching effect will be affected by interventions(micro experiment time,subject,class hour long,the types of courses,resources platform,and other teaching methods),the research object(number of research,education category,geographic area),type of research(source journals,fund support)adjustment variables such as the influence of d ifferent level.The implications of this study are as follows :(1)the application normalization of micro-course teaching needs to be further promoted.(2)The application research of micro-course teaching in multi-discipline and multi-learning segment needs to be further deepened.(3)Pay attention to the sustainability of micro-course teaching in promoting the teaching effect.(4)Pay attention to the design and production of micro-video.(5)There is still a lot of space for the research on the teaching mode combining micro-class with other teaching methods.
