  1. MCMSMining Course Management Systems Samia Oussena Thames Valley University

  2. Project Aim • MCMS is a JISC funded project which aims to use data mining to support TVU strategy on students retention and course monitoring.

  3. Project Overview student information data sources student records BB etc. MCMS monitors student information sources and generates events, reports, advice etc. to identify potential divergence from and to recommend remedial actions for prescribed educational processes. MCMS educational process descriptions events reports advice etc.

  4. Project Objectives • Conduct a detailed survey of the stakeholder’s main areas of concerns and good intervention practices. • Conduct a data analysis of the institution database systems relevant to the problem areas. • Propose and implement a data integration model. • Build and evaluate data mining models. • Build an application that will use the data mining model and implement intervention requirements.

  11. Data Mining Process Transfer data to fit the data mining models first. Apply feature importance and associate rules to find the relation among data features. Then classify data and extract human friendly rules and patterns. Regression is then applied to predict future behaviours. Pre-Processing Feature Importance/ Associate Rules Classification/ Clustering Regression/ Prediction 1. Pre-Process the data 2. Find feature relations 4. Predict feature behaviours 3. Group data and extract possible rules

  12. Data Mining Pre-Processing • Summarize data on different levels (e.g. overall module average mark , total number of resits, total book loans and etc) • Discard Short Courses data (150 courses 100) • map the entry Certificate into numeric value

  13. Finding relations: Student Data “Is the student performance, such as average mark, drop out, pass/fail related to student background profile?” “Is the student performance, such as average mark, drop out, pass/fail related to Blackboard System and Library Usage?”

  14. Finding Relations : student data • Student performance is not related to the gender, race, age, disability, nationality etc. • But is related to which year he/she is studying (Current_StudyYear), BlackBoard Usage (BB_Usage) and slightly related to Library Usage (Library_Usage) However, the frequency of BB access is not related to the student academic performance. Even for the same module, there are students with very high marks that use BB very rarely, whereas some frequent users have very low marks..

  15. Finding Patterns: student data “Do part time students behave differently from full-time students?” Part time students enroll with higher certificate, get higher mark, have less resit, dropout less, but use library and BB less.

  16. Prediction Result “Will Student A drop out or not?”

  17. Conclusion and Future work • The JISC funded MCMS project at Thames Valley University aims to apply Data Mining technology to institution data sources in order to identify predictive rules that can be used to detect and improve issues related to student retention • The project has addressed data integration issues including technical, organizational and legal issues • The project built and evaluated data mining models that identify student patterns and would predict behaviour • Future Work: • Build a personalised intervention system • Run a pilot in the next academic year
