We describe and evaluate an approach to student learning that aims to instil a culture of formative assessment based on peer-assisted self learning, instead of a marks-based culture in which learning effort is rewarded with marks that contribute to the student's degree. The idea is for suitably qualified thirdand fourth-year undergraduates to assist in the running of weekly first-year tutorials...

In this paper we compare computerized environments in which students complete proof construction exercises in formal logic. After being given a pretest for logical aptitude, three matched groups were presented identical course material on logic for approximately five weeks by a computer. During the treatment, all students were required to complete several hundred proof construction exercises. T...

Proponents of classroomand team-based exercises argue that structured group problemsolving activities enhance student learning. A team-based, guided design exercise conducted annually from 1985-2002 supports the claim that most teams reach superior decisions than individual students left to their own knowledge. However, a very small percentage of teams were not successful reaching a learning go...

Our goal in this work is to create a more collaborative learning environment in the classroom, by designing and implementing a system infrastructure to support easy use and management of a large shared (tiled) display. Through this shared display space, instructor and student interaction is facilitated. This large display space provides the primary means of presentation of lecture material, all...

One of the principal dimensions of expertise of a skilled designer is what has been called procedural know-how; experiential knowledge that enables goal-oriented problem solving. In this paper, we present an experiment in machine skill acquisition in a very small and narrow, but yet a demonstrative well-defined design domain through a program that acquires procedural know-how automatically by l...

We applied the Protégé methodology for building knowledge-based systems to the domain of antiretroviral therapy. We modeled the task of prescribing drug therapy for HIV, abstracting the essential characteristics of the problem solving. We mapped our model of the antiretroviral-therapy domain to the class of constraint-satisfaction problems, and reused the propose-and-revise problem-solving meth...

BACKGROUND Cognitive therapy has been found to be effective in decreasing the recurrence of suicide attempts. A theoretical aim of cognitive therapy is to improve problem-solving skills so that suicide no longer remains the only available option. This study examined the differential rate of change in problem-solving appraisal following suicide attempts among individuals who participated in a ra...
