| The national medium and long-term educational reform and development program(2010-2020) pointed out we need to strengthen the development and application of quality education resources and promote the popularization of quality education resources sharing. Micro-lesson as micro learning era of educational information resources, has short, focused, fine design, easy to spread and other characteristics, greatly adapt to the teaching and learning reform of " Internet plus "era, provide personalized learning and teaching support greatly , has received extensive attention. With the rapid development of micro-lesson, it also bring prominent problem, like crudely made, the utilization rate is not high and the effect is not obvious and so on. The research of micro lesson throughout, mostly concentrated in the theoretical study, design research,development and application aspects, few scholars have constructed the evaluation index system from their own point, but the evaluation methods focus on using subjective estimate method , like AHP, fuzzy comprehensive evaluation and so on, has some subjective limitations.Based on the Ministry of education, humanities and Social Sciences planning fund project "Research on copyright protection of network video teaching resources based on digital watermarking" (NO:14YJA880058) and the research project of the Central University of Central China Normal University "Research on trusted management and scheduling mechanism of service resources in cloud computing environment"(NO:CCNU16A02036), we stared our studies. Firstly, this paper defined the related concepts and the theoretical basis of this thesis. Secondly, summarized and analyzed the relevant indexes of the micro lesson evaluation. On the basis of summarizing and analyzing the relevant indexes of the micro lesson evaluation, this paper had constructed a relatively perfect evaluation index system of micro lesson by using the expert investigation method. Then we introduced the information entropy theory into the evaluation of micro lesson, selected micro lesson from representative micro lesson platform. And we used the entropy weight method to evaluate the micro lesson, verified the rationality of index and method and the feasibility, explored a new micro-lesson evaluation method and model. Finally, according to the nature of entropy weight, this paper analyzed the distribution of the weight of the index, reflected the development of micro course.This paper was divided into six chapters:The first chapter of the paper introduced the background and significance of this study, reviewed the domestic and foreign research status of micro-lesson and defined the content and methods of this research and innovation.The second chapter defined the concept of micro-lesson, evaluation and micro-lesson evaluation, introduced the theoretical basis of this study, the theory of educational evaluation, the cognitive theory of multimedia learning and information entropy theory.The third chapter introduced the basic process of the construction of the evaluation index of micro-lesson, defined the basic steps of the index weight of entropy method, and laid a theoretical foundation for the orderly development of this study.The fourth chapter constructed the evaluation index system of micro lesson. And selected the micro lesson related research experts, ultimately determined the perfect micro lesson evaluation index system through two rounds of expert consultation.The fifth chapter determined the weight of evaluation index of micro lesson. By using entropy method, this paper selected micro classes from the representative micro platform, and the expert used the micro lesson evaluation index to judgment the micro lesson. We got the weight of each index, and verify the reasonableness of this index.Finally, according to the nature of the entropy weight method, the distribution of the weight of the index is analyzed.The sixth chapter summarized the research results and shortcomings of this paper,clearly the direction of future research. |
