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...

pg-MathTrails is an application developed to assess math skills of school students. It includes i) topic hierarchy to categorize the questions, ii) question template repository using which teachers can add different types of questions, iii) question play module to play questions, iv) student evaluation module to evaluate student performance, and v) recommender that recommends videos residing in...

In this paper, we present a data-based user modeling framework that uses both unsupervised and supervised classification to build student models for exploratory learning environments. We apply the framework to build student models for two different learning environments and using two different data sources (logged interface and eye-tracking data). Despite limitations due to the size of our data...

Increasingly, higher education institutions are exploring the potential of learning analytics to predict student retention, understand learning behaviors, and improve student learning through providing personalized feedback and support. The technical development of learning analytics has outpaced consideration of ethical issues surrounding their use. Of particular concern is the absence of the ...

We examine whether stringent formal sector borrowing requirements in developing countries restrict credit access and the potential of asset-collateralized loans. When a Kenyan dairy cooperative exogenously replaced high down payments with loans collateralized by the asset itself a large water tank loan take-up increased from 2.4% to 41.9%. In contrast, substituting joint liability requirements ...

METHODS The authors designed a survey instrument to examine the effect of involvement in a student-run free clinic project (SRFCP) on medical student self-reported attitudes toward the underserved and interest in primary care. From 2001-2010, first-and second-year medical students in an introductory service-learning elective course rated each of 15 statements on a seven-point Likert scale pre/p...

BACKGROUND Teachers can deliver feedback using person ('you are clever') or process terms ('you worked hard'). Person feedback can lead to negative academic outcomes, but there is little experimental research examining the impact of feedback on children's perceptions of the student-teacher relationship. AIM We examined the effects of person, process, and no feedback on children's perceptions ...

Formative assessment (FA) techniques, such as pre-class assignments, in-class activities, and post-class homework, have been shown to improve student learning. While many students find these techniques beneficial, some students may not understand how they support learning or may resist their implementation. Improving our understanding of FA buy-in has important implications, since buy-in can po...
