Automatic assessment systems generally support immediate grading and response on learners’ submissions. They also allow learners to consider the feedback, revise, and resubmit their solutions. Several strategies exist to implement the resubmission policy. The ultimate goal, however, is to improve the learning outcomes, and thus the strategies should aim at preventing learners from using the res...

For self-regulated learning to be effective, students need to be able to accurately assess their own performance on a learning task, and to select an appropriate new learning task in response to that self-assessment. This study investigated the use of video-based modeling examples to teach selfassessment and task-selection skills. Students in both the experimental and control condition observed...

In this paper we present evidence that simple problem solving in the dog is strongly influenced by the relationship with the owner. Twenty-eight dog-owner pairs were observed in a novel situation and when performing a simple problem-solving task. Dogs were categorized according to their relationship with the owners (`companionship" or "working relationship"). In addition to the behavioral analy...

People that show good performance in problem solving tasks make also errors. Psychological theories of human error predict that those errors are to some extend the consequence of the difficulties that these people have to adapt to new environmental conditions. This paper describes two experiments and a research methodology designed to test this hypothesis.

This paper treats risk based on the notions of credibility measure and credibility expected value. Firstly, the paper derives and discusses the credibility expected value. Secondly, the paper presents a new method of analysis of possibilistic portfolios. The new step is a construction by which with a possibilistic portfolio one associates a probabilistic portfolio. The problem solving of possib...

Student problem-solving ability appears to be tied to the representational format of the problem (mathematical, pictorial, graphical, verbal). In a study of a 367-student algebra-based physics class, we examine student problem solving ability on homework problems given in four different representational formats, with problems as close to isomorphic as possible. In addition, we examine students’...
