This study presents a shared document-based annotation tool, EDUCOSM. Usefulness of the system is empirically evaluated in a real-life collaborative learning context. Relationships between learner's self-rated use of learning strategies, cognitive outcomes, and completion of various tasks in the system are investigated. An empirical study (n=31) was(More)
NB. The HIIT Technical Reports series is intended for rapid dissemination of results produced by the HIIT researchers. Therefore, some of the results may also be later published as scientific articles elsewhere. He studies evaluation and testing of computer-supported learning environments. Abstract A shared document-based annotation tool was presented, and(More)
Many of the possibilities of Web-based education are still unexplored. It seems that novel ways of thinking about both learning and technology are needed to get beyond the limitations of the traditional classroom setting. In this paper we introduce EDUCOSM, which focusses on the possibilities of collaboration and the open-ended nature of the Web. Its main(More)
The molecular basis of human cognition is still poorly understood, but recent advances in finding genetic mutations that result in cognitive impairment may provide insights into the neurobiology of cognitive function. Here we review the progress that has been made so far and assess what has been learnt from this work on the relation between genes and(More)
In spite of advances in educational technology, most Web-based computer science courses rely on costly pre-made learning materials. By shifting the emphasis to peer-to-peer learning and other student-centred learning principles, more meaningful learning process can be accomplished, without preparing stand-alone Web-courses. A course applying these(More)
An adaptive on-line questionnaire, named EDUFORM 1 , is based on Bayesian statistical techniques that both optimize the number of propositions presented to each respondent and create an individual learner profile. Adaptive graphical user interface is generated partially (propositions of the questionnaire, collaborative actions and links to resources) and(More)
Why do some adolescents respond to interpersonal conflicts vengefully, whereas others seek more positive solutions? Three studies investigated the role of implicit theories of personality in predicting violent or vengeful responses to peer conflicts among adolescents in Grades 9 and 10. They showed that a greater belief that traits are fixed (an entity(More)
Bayesian modeling can be used for providing adaptation in an on-line questionnaire. In our research, adaptation means selecting the questions presented to the user in such a way that the total amount of answers required for profiling the user is minimized. In the article, we present the motivation to use Bayesian modeling as a basis for the adaptation and(More)
