Construction Of Evaluation Index System For Precision Teaching

The rapid development of intelligent information technology with mobile Internet,big data,and sensor networks as the core has promoted the leap of various fields of society from networking and information to intelligence,and education has also accelerated the integration with information technology.Intelligent information technology has activated precision teaching,and educational researchers and practitioners are conducting educational practice that integrates subject teaching with precision teaching.However,the quality of subject precision teaching requires evaluation tools to measure.This research will focus on the precision teaching of mathematics in junior high school,and try to construct a scientific evaluation index system.So,what are the key elements and characteristics of precision teaching? How to determine the evaluation index of mathematics precision teaching in junior middle school? How to distribute the index weights of mathematics precision teaching evaluation in junior high school?First of all,by analyzing the research status of precision teaching at home and abroad,the concept of precision teaching is defined,the connotation of precision teaching is analyzed,and five key characteristics of precision teaching are extracted: "Precise optimization of hierarchical learning objectives" "Precise design","precise recommendation of personalized learning path","precision generation of dynamic learning evaluation","precision support of intelligent information technology".Secondly,through the analysis of the essence of junior high school mathematics teaching,the essential characteristics of junior high school mathematics are refined: taking students 'mathematics literacy as the goal orientation,mathematics content as the carrier,autonomous,cooperative and inquiring learning methods as the path,guided by scientific evaluation.Combining the characteristics of the two,the five characteristics of mathematics precision teaching in junior high school are sorted out: the development of precision teaching goals with the cultivation of students 'mathematical literacy as the core,the precise design of personalized mathematics content,and the precise recommendation of personalized mathematics learning paths,Accurate generation of dynamic mathematics learning evaluation,accurate support of intelligent mathematics resources.Therefore,this article uses these five characteristics as the first-level indicators of junior high school mathematics precision teaching.Under the principles and norms of evaluation index construction,this paper refines 12 second-level evaluation indicators and 30 evaluation standards,and initially constructs a junior high school mathematics evaluation indicator system..After two rounds of consultation with experts,the preliminary evaluation index system was revised,and finally the junior middle school mathematics precision teaching evaluation system was established by 5 first-level indicators,12 second-level indicators and 34 evaluation standards.Finally,using the analytic hierarchy process,the "Questionnaire for Evaluation of Relative Importance of Mathematics Precision Teaching Evaluation Index for Junior Middle Schools" was compiled and distributed to the 15 experts who gave opinions in the first two rounds.The expert's judgment data is input into the analytic hierarchy process software yaahp7.0,and the statistical results are averaged to obtain the weight values of all levels of indicators.In the follow-up research,theoretical research and action research should be combined to analyze the characteristics of different types of mathematics classes,refine the evaluation indicators of junior high school mathematics precision teaching,so as to enhance the adaptability of junior high school mathematics precision teaching.
