A peer feedback tool (Radar) and a reflection tool (Reflector) were used to enhance group performance in a computer-supported collaborative learning environment. Radar allows group members to assess themselves and their fellow group members on six traits related to social and cognitive behavior. Reflector stimulates group members to reflect on their past,(More)
BACKGROUND Learning styles are often assessed through students' self-reports on instruments such as Vermunt's Inventory of Learning Styles (ILS). Recent research, however, has questioned the adequacy of questionnaires for the assessment of learning styles. AIMS The objective of this paper is to evaluate methods of learning style assessment as a means for(More)

Help seeking behavior in an intelligent tutoring system was analyzed to identify help seeking strategies, and it was investigated whether the use of these strategies could be predicted by achievement goal scores. Five strategies were identified, three of which were predicted by achievement goal scores. strategy was predicted by mastery avoidance goals, the(More)
Most studies on malaria-parasite digestion of hemoglobin (Hb) have been performed using P. falciparum maintained in mature erythrocytes, in vitro. In this study, we examine Plasmodium Hb degradation in vivo in mice, using the parasite P. berghei, and show that it is possible to create mutant parasites lacking enzymes involved in the initial steps of Hb(More)
This study investigated whether a peer feedback tool and a reflection tool would enhance group performance in a computer-supported collaborative learning environment. The underlying assumption was that group performance can be positively influenced by making group members aware of how their social and cognitive behavior is perceived by themselves, their(More)
This article focuses on the design of competency-based performance assessment in e-learning. Though effort has been invested in designing powerful e-learning environments, relatively little attention has been paid to the design of valid and reliable assessments in such environments, leaving many questions to educational developers and teachers.
