The trend toward designing an intelligent distribution system based on students’individual differences and individual needs has taken precedence in view of the traditional dormitory distribution system,which neglects the students’personality traits,causes dormitory disputes,and affects the students’quality of life and academic quality.This paper collects freshmen's data according to college students’personal preferences,conducts a classification comparison,uses the decision tree classification algorithm based on the information gain principle as the core algorithm of dormitory allocation,determines the description rules of students’personal preferences and decision tree classification preferences,completes the conceptual design of the database of entity relations and data dictionaries,meets students’personality classification requirements for the dormitory,and lays the foundation for the intelligent dormitory allocation system. 展开更多

The classroom is an important place for“three guarantees”education.Classroom culture refers to a group culture with both teachers and students as the main body,the classroom space as the carrier,and spiritual connotation as the core.The creation of classroom culture with school characteristics,characteristics of the times,and Chinese characteristics can reflect the aesthetic perspective and value orientation of the school,which has far-reaching significance for the growth of students and their future development.This paper takes the construction of classroom culture in colleges and universities as the research subject,obtains real data,and conducts variable analysis through questionnaire survey and structured interview,with the aim of enriching the educational function of the classroom.It involves how the classroom culture pays attention to the current life,needs,and desires of college and university students,along with the problems and functions that should be improved in the traditional construction.This paper also discusses and reshapes the new paradigm of classroom culture construction in colleges and universities based on the combination of student growth,subject areas,school culture,and advanced technology. 展开更多

With the goal of establishing morality and nurturing people,university catering is thought to be one of the key components in the construction of“double first class”universities,which supports and leads the reform of education modernization.In this study,the common problems in the university catering were analyzed,and research was done through questionnaires and interviews.This study takes Beijing colleges and universities as the research object to understand the needs of students and teachers and aims to build a“new ecology”of university catering,and vigorously promote the construction of green campuses. 展开更多

The“3060”goal demonstrates China’s responsibility in actively responding to global climate,enhances China’s voice and influence in climate governance,and sets an example of energy conservation and emission reduction for developing countries.As the main institutions that educate people for the Party and the country,colleges and universities have the responsibility to explore the realization path of carbon peak and carbon neutralization against the new problems encountered in the practice of energy conservation and emission reduction in colleges and universities.In response to the national strategy and the action plan of the Ministry of Education,taking the carbon practice of China University of Geosciences(Beijing)as the starting point,this paper conducts benchmarking research on the path of carbon peak and carbon neutralization in universities through the ecological factor method,campus carbon footprint,and questionnaire analysis. 展开更多
