Investigating the benefits of worked examples in a constraint-based tutor

published by admin on Tue, 10/03/2015 - 22:26

Learning from worked examples (WE) has been shown to be beneficial for novices. In this talk I will present three studies we have conducted in the context of SQL-Tutor, a constraint based system. The first study showed that interleaving WE with supported problem solving is an optimal choice compared to using either of those two types of learning in isolation. In the second study, we added an adaptive strategy for selecting WE or problems to be given to the learner, which proved to be superior to the fixed sequence of examples/problems.

TARLAN: A Simulation Game to Improve Social Problem-Solving Skill of ADHD Children

In this presentation, Atefeh will talk about her Ph.D. research looking into computer-based training that she developed to teach social skills to children with ADHD. More information is available at: http://www.csse.canterbury.ac.nz/seminars/abstracts/558.shtml

Supporting Collaborative Learning and E-Discussions Using Artificial Intelligence Techniques

published by admin on Wed, 20/03/2013 - 08:36

An emerging trend in classrooms is the use of networked visual argumentation tools that allow students to discuss, debate, and argue with one another in a synchronous fashion about topics presented by a teacher. These tools are aimed at teaching students how to discuss, argue and think critically, important skills not often taught in traditional classrooms. Yet how do teachers support students during these e-discussions, which happen at a rapid pace, with possibly many groups of students working simultaneously?

Supporting Learning Naturally: The Ecological Approach

published by admin on Sat, 30/04/2011 - 10:30

Abstract

This talk will overview my evolving perspectives on the design of environments to support learning. The basic philosophy is that such environments must be deeply aware of the surrounding context of learning . technical, personal, social, and cultural . and must be adaptive to differences in this context. This philosophy has led to the development of a framework for supporting learning called the ecological approach that allows a system to naturally evolve and change as the learning context changes. The talk will present past and current experiments in building ecological systems, and will look forward to possible future applications including the creation of a lifelong learning companion.

Learning Crew Scheduling Constraints from Historical Schedules

published by admin on Thu, 09/12/2010 - 11:23

Abstract

There are a number of rules and regulations that govern the workload of airline crew. Although some constraints are formally documented, there are many others based on established practice and tacit understanding. Consequently, the task of developing a formal representation of the constraints that govern the working conditions of an airline's crew requires extensive time and effort involving interviews with the airline's crew schedulers and detailed analysis of historical schedules. In this talk, I will present a system that was developed to learn crew scheduling constraints from historical crew schedules. The results of the evaluation conducted with crew schedules from two commercial airlines showed that the system is capable of learning majority of the minimum rest constraints.

From Primary School Arithmetic to Neuroradiology: computers as motivators and envisioning devices in education

published by admin on Tue, 01/06/2010 - 18:10

Abstract

Computers can play a wide variety of roles in education. One such role is as a device to motivate learning. Another is to provide novel ways to see and understand a subject area. This talk will describe a number of research projects undertaken by the Human Centred Technology Research Group at Sussex University. One project involved primary school children where tablet computers were used to bridge between school and home.
Another involved undergraduates learning programming where the system took account of the pressures of the work and prescribed neck and shoulder exercises with surprising results. The final example describes how radiologists learning to interpret MRI scans were provided with new ways to relate MRI images to brain diseases.

Motivating Computer Tutors

published by admin on Thu, 13/05/2010 - 17:49

There is increasing interest in building learning environments that pay attention to the motivational dimension of learning, in particular finding ways to maintain or improve the student's motivation while using a computer-based tutor. This talk will outline current progress in this field with reference to work from various research groups including the Human Centred Technology Research Group at Sussex University.
