Research And Implementation Of Classroom Interaction Data Analysis System

In the context of the increasing emphasis on formative evaluation in higher education,the discussion of process evaluation and summative evaluation is also increasing.Based on the data of college interactive platforms,this paper designed a model to calculate students' process evaluation scores.Also,students' test scores will represent the summative evaluation.Comparing the results of the two evaluations to provide teachers with analytical services for process evaluation.Helping teachers understand more about the design of their classroom procedural evaluation and the impact of classroom interaction platforms on students' test scores.Classroom interactive data analysis system enables analysis of platform student data modeling,and has made a relative comparison between the classroom interaction data and the test score representation.Get classroom formative evaluation results.The system provides the following four features: 1)Analyze the student's attributes in classroom interaction,establish a platform for students' interaction attitude and answering ability model,and calculate the correlation coefficient between each attribute and test scores;2)Classify students,grouping of excellent grades into one category,and so on.The performance of students on the platform is also classified;3)Find out the relationship between the classification of students' performance on the platform and the classification of test scores,and filter out the effective rules that students' performance on the platform can lead to.4)Output results report,the system will output classroom interactive data and student test scores associated analysis report,to serve the necessary teachers.The system passed the functional test.This paper has carried on the demand analysis,the feature realization and the feature test with dozens of real classrooms.The relevance of platform attributes and test scores due to differences in the use of platforms and depth of use of classroom teachers is strong and weak.Overall there are still strong rule support from excellent performance of platform to excellent grades and poor performance of platform to poor grades.
