I have taught and conducted research in online learning for a number of years. I currently teach an online class (Human Abilities in Learning, aka HAL Online) in which undergraduates study conceptual material about the science of learning, then deepen their understanding of the material by using it in small-group collaborative problem solving that takes place asynchronously online. Important co...

There is concern regarding the loss of ecosystem goods and services as a result of land use changes such as the expansion and intensification of agricultural activities. Assessments of these interactions require innovative analyses that combine qualitative and quantitative economic analyses. The Millennium Ecosystem Assessment framework was applied to a peri-urban region in British Columbia, Ca...

A Classification Model for Human Error in Collaborative Systems The primary focus of the work reported in this thesis is to investigate and provide a means by which the occurrence of human error in collaborative systems can be better understood. The thesis suggests that much can be gained from looking at human error from a collaborative perspective as opposed to more traditional cognitive and b...

Service Orientation has been an extensively used approach to model the services Collaborative Networks' (CN) members are willing to provide to customers. The evolution of this paradigm has followed an improvement path since its early forms. Nevertheless bottlenecks still exist, namely in what concerns: 1) a gap between the business and the information and communication technology perspectives; ...

Integrating wiki-based activities into education encourages development of students’ competencies that are important for their future professional life. As wikis support social learning and interaction, when working with them students learn to cooperate, plan and organize collaborative tasks, create concepts, express ideas, etc. Many teachers recognize undeniable benefits of a wiki in learning ...

A key challenge posed by narrative-centered learning environments is dynamically tailoring story events to individual students. This paper investigates techniques for sequencing story-centric embedded assessments—a particular type of story event that simultaneously evaluates a student’s knowledge and advances an interactive narrative’s plot—in narrative-centered learning environments. We presen...

Students learning effectively in groups encourage each other to ask questions, explain and justify their opinions, articulate their reasoning, and elaborate and reflect upon their knowledge. The benefits of collaborative learning, however, are only achieved by active, wellfunctioning teams. This paper presents a model of collaborative learning designed to help an intelligent collaborative learn...

We present a reflection-on-action system supporting students’ reflection and self-assessment after a tabletop brainstorming learning activity. Open Learner Models (OLMs) were core to the reflection task, to scaffold student’s self-assessment of egalitarian contribution; and group interaction from ideas sparked from each other. We present multiple OLMs to the group generated from logs automatica...
