Enterprise systems (ES) are important business software which can be difficult to implement, while the failure to account for organisational culture can lead to projects that are expensive and late. However most of the existing research has focused on national level culture. As such little is known of how organisational culture influences the implementation of enterprise systems. This ongoing r...

Student modelling systems must operate in an environment in which a student’s mastery of a subject matter is likely to change as a lesson progresses. A student model is formed from evaluation of evidence about the student’s mastery of the domain. However, given that such mastery will change, older evidence is likely to be less valuable than recent evidence. Data ageing addresses this issue by d...

Virtual or Managed Learning Environments (VMLEs) cannot be fully effective unless well-integrated with existing campus information systems. Institutional planning for the UK Research Assessment Exercise (RAE) has provided an unexpected impetus at the University of Bristol. The DataHub, a reporting database created initially to back-end a locally developed Web application (IRIS) to support the R...

Predictive models are able to predict edX student grades with an accuracy error of 0.1 (10%, about one letter grade standard deviation), based on participation data. Student background variables are not useful for predicting grades. By using a combination of segmentation, random forest regression, linear transformation and application beyond the segmented data, it is possible to determine the p...

BACKGROUND Little is known about the technical adequacy of portfolios in reporting multiple complex academic and performance-based assessments. We explored, first, the influencing factors on the precision of scoring within a programmatic assessment of student learning outcomes within an integrated clinical placement. Second, the degree to which validity evidence supported interpretation of stud...

In this paper, we explore student dropout behavior in Massive Open Online Courses(MOOC). We use as a case study a recent Coursera class from which we develop a survival model that allows us to measure the influence of factors extracted from that data on student dropout rate. Specifically we explore factors related to student behavior and social positioning within discussion forums using standar...
