- Abstract:
-
To make full use of the educational big data resources and promote the sound development of teaching reform, this paper applies several extension data mining methods, including an extenics support vector machine, an improved k-means algorithm based on extension distance, etc., and the Pearson’s correlation coefficient, to analyze the usual homework, midterm, and final examination results of a college students’ mathematics course, to explore the scientificity of test paper design, students’ mastery of knowledge points, and which topics are the main factors affecting students’ performance. Furthermore, some advance information is given to each student to tell them which point they should focus on in this course later. This paper applies the constantly developing, cutting-edge scientific research methods to the education and teaching that need constant reform and makes full use of the huge student achievement data that has been sleeping for a long time. It has played a good example of scientific research guiding teaching and teaching feeding scientific research.
