An Exploration of Association Rules for Doctoral Graduation Factors:Group Image Features and Type Differences
Doctoral education aims at cultivating high-level talents with academic innovation ability,shouldering the important task of knowledge production and promoting economic and social development.In the context of big data,the educational data of doctoral training process was used to explore the association rules between doctoral graduation time and training links,discover the main reasons for delayed graduation of doctoral students,and analyze the group characteristics of doctoral graduates at different times,providing objective scientific guidance for strengthening the management of doctoral training and improving the rate of doctoral graduation in universities.Based on the acquisition of five types of data from the management big data system of graduate students in a university,namely student enrollment information,basic information of supervisors,comprehensive quality performance,campus behavior data,and research and learning situation,data processing was integrated to form a data set,feature extraction and label system construction were carried out,and FP-Growth algorithm was used to explore the association rules of all labels and doctoral graduation factors.Finally,the group portraits of three kinds of doctoral students who graduated on time,graduated after the deadline and failed to graduate after the deadline were depicted,and the different characteristics of the three kinds of group portraits were compared and analyzed.The results show that there is a strong correlation between the admission method,course score,proposal situation,the number and completion time of scientific research results,whether they won scholarships and honors during study,and the graduation time of graduation thesis.The age of doctoral students,whether the university is"double first-class"before entering the university,the age of the supervisor,the years of the supervisor as a doctoral supervisor,the number of students under the guidance of the supervisor,the campus behavior and the graduation time of doctoral students are not strongly correlated;there are two kinds of typical group portraits for scheduled and delayed doctoral students,and three kinds of typical portraits for delayed doctoral students.The differences of the group portraits of three kinds of doctoral students mainly lie in three aspects:academic interest,academic foundation and academic ability.In order to improve the quality of doctoral training and improve the graduation rate of university doctoral students,it is necessary to break the rigid restrictions and invisible discrimination to ensure the effectiveness of the selection of excellent students;the second is to strengthen the process supervision and shunt out to ensure the scientific management of the training process;the third is to pay attention to curriculum supply and basic training to ensure the fluency of scientific research practice;and the fourth is to protect academic aspirations and physical and mental health of doctoral students,and to motivate the enthusiasm of scientific research,innovation and exploration.
