The flipped classroom teaching shifts from knowledge-centered to competency-centered. The flipped classroom teaching model has been adopted by more and more college teachers. In the process of flipped classroom teaching, the quality of students' online learning before class is related to the success or failure of the flipped classroom teaching process. Flip class online learning time is a specific time and not a probability. This paper uses the MCMC algorithm to analyze the online learning time of the flipped classroom, and analyzes the student learning time in the form of probability.","PeriodicalId":438151,"journal":{"name":"Proceedings of the 5th International Conference on Distance Education and Learning","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114623367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Paper management mode will not meet the needs of the development of modern society. We should strengthen the design and construction of government procurement system under the cooperation of modern equipment such as information technology, and effectively supervise the procurement process.

As a result, some biostatistics instructors balk at the idea of teaching conceptual knowledge to MPH students, often content with imparting procedural skills. Teaching a concept-oriented biostatistics course for online MPH students would seem doubly challenging. The author cites concrete examples from a categorical data analysis course to show how a novel teaching approach can render the online environment fertile ground for teaching conceptual knowledge of biostatistics to MPH students. Central to the new approach is a large set of carefully designed computing exercises that concretize abstract statistical concepts. Students use a small data set to compute a puzzling quantity such as the deviance according to the quantity's theoretical definition and then compare their results with that generated by a reputable statistical package. Students derive intellectual satisfaction from these concept-oriented computing exercises, as suggested by end-of-semester course survey data.","PeriodicalId":438151,"journal":{"name":"Proceedings of the 5th International Conference on Distance Education and Learning","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117166926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After systematically searching online bibliographic databases, 23 relevant papers were located and included in the study. The results indicate that (1) SP construction was mainly based on the theory about learning theories, particularly social constructivism; (2) SP analysis was mainly about learning style, academic achievement, learning motivation, learning anxiety, etc.; (3) The E-learning platforms that used to collect data can be divided into two groups: adaptive learning styles and intelligent learning styles; (4) The computing mechanism includes Bayesian networks, decision trees, etc. As SP is still at its early developing stage, it has some research limitations: not only lack of studies in investigating all cognitive aspects, but also lack of factors that considered in constructing an overall student profile. SP would be employed extensively in education field in the near future if it can address the challenges mentioned above.","PeriodicalId":438151,"journal":{"name":"Proceedings of the 5th International Conference on Distance Education and Learning","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122967709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
