Teaching Decision Making Based On Data Analysis Of Intelligent Teaching Platform

Big data technology has given birth to an intelligent teaching platform that can collect learning data to support teaching decision-making.However,the extraction and analysis of platform data still puzzles frontline teachers,resulting in teachers on the intelligent teaching platform unable to make reasonable use of data for teaching decision-making.Based on the analysis of the formation of platform data,starting from the mature teaching decision-making model,through the data demand analysis of teaching decision-making,combing the decision-making system based on teaching data,the decision-making model based on platform teaching data is established.The research results of this paper are as follows:1.Teaching decision-making involves four aspects of concern,including goal,content,method and management.Platform data is mainly generated from the monitoring of teaching process.Therefore,platform based teaching decision-making occurs more in the stage of teaching interaction,and the decision-making of teaching method and management category is the focus of teachers' attention.2.The data of decision-making mainly comes from the monitoring of students' behavior and learning state on the platform.Teachers should be good at extracting this part of data to adjust teaching methods and management measures of teaching activities in real time,and adjust the decision-making of objectives and contents according to the actual situation of different students,so as to take care of individual students and teach students according to their aptitude.3.Monitoring data need to be analyzed to support decision-making.Teachers should be good at using platform data for statistical analysis,S-P table analysis,relevant parameters and attention coefficient twodimensional modeling analysis,in addition to the decision-making information provided by the platform itself after model analysis,so as to realize accurate teaching.4.The decision-making model based on platform teaching data is established,and the application of the model is explored through examples to provide experience for teachers' teaching decision-making practice.On the basis of literature analysis,this paper explores the composition of intelligent teaching platform and the application of data in the platform,discusses the composition of teaching decision-making system based on platform data and the data demand in decision-making.Based on the comparative analysis of some authoritative teaching decision-making models,this paper selects Westerman 's teacher decision-making model as the basis,constructs a teaching decision-making model based on platform data analysis,and applies this model to the teaching of photography foundation course to explore how to extract data,analyze data,and support teaching decision-making from the platform,in order to provide teachers with Decision making guidance to improve teachers' teaching professional ability and data literacy.At the same time,it provides case reference for data-based teaching decision-makers.
