Research On Design And Application Of Micro-course In University Physics Virtual Experiments

In recent years, with the continuous progress of information technology and internet, mobile learning and online education have been vigorous developing. Teaching resources gradually tend to show the characteristics of openness, sharing and diversity, while micro-course, micro-learning, micro-teaching and other concepts have occurred. The document of Ministry of Education has published ten-year educational information development planning (2011-2020), which lays stress on important revolutionary influence and supporting role of the current education reform and development in 2012.University Physics virtual experiment plays an important role in the teaching system of science and engineering, while the physics experiment teaching is facing the difficulties of single teaching mode and poor teaching resources. Once the university Physics virtual experiment and micro-course are combined, with the help of network, the experiment can be carried out anytime and anywhere. Through micro-course, the teaching quality of experiment teaching, students’experimental skill and integrated diathesis can be completely improved. In order to summarize and analyze the current situation of Physics, the study conducted the questionnaire investigation, from which we have found that there were series of problems such as the single teaching mode, the lack of teaching resources, fixed teaching mode in current virtual experiment teaching, which confirms the necessity of micro-course.According to the actual situation and the content and the demand analysis of the Physical virtual experiment projects, based on the theory of instructional design, personalized learning, mobile learning, we found the feasibility of micro-course in college physics.Combined the resources and course characteristics of micro-course, we analyzed the development tools, software and network platform, and extracted the design principles and flow chart of the virtual experiment micro-course, and summarized the virtual experiment teaching model based on the micro-courses. To verify the effectiveness of the micro-course, this paper has selected electromagnetic experiments such as Hall Effect to design a series of micro-courses. And we carried out empirical research through surveying sophomore students of the science and engineering in Hunan University. The applicants were randomly divided into three groups in the experiment, and the experimental group was the micro teaching and the mixed teaching group, and the control group was the traditional teaching group. The teaching of the experimental group was based on the WeChat public platform, through which we release the micro-course and conduct individualized instruction in the public number of "Physics experiment group". Through the analysis of the learners’ evaluation data, we verify that the experimental teaching based on micro-course can promote learners’understanding of the experimental project to a certain extent, and stimulate the enthusiasm of the learners, enhance the comprehensive ability of the students, and realize the transfer of knowledge.
