Knowledge is commonly socially constructed, through collaborative efforts towards shared objectives or by dialogues and challenges brought about by different persons' perspectives.

In this study, it was investigated whether, and to what extent, Web 2.0 technologies, actually Weblogs, can be a suitable instrument for enhancing the practice of distributed learning. In educational settings, which are based on traditional lectures many students begin serious study shortly before the exam. However, from previous empirical research, it is known that the practice of distributed learning is much more conducive to retaining knowledge than that of massed learning. A 2x2 factorial design (within -- repeated measures) with pre-test and post-test in a real life setting was applied; the study lasted for the whole summer term 2007. Participants were N=28 computer science undergraduates of Graz University of Technology. We randomly assigned them to two groups of equal size: The experimental group given the Weblog treatment are referred to as Group W; whereas the control group with no access are referred to as Group C. Students of group W were instructed to use the Weblog for developing their paper and studying during the lecture and they were requested not to reveal their group affiliation. The results showed that performance scores of group W were significantly higher than that of group C. This demonstrates that Weblogs can be an appropriate instrument to supplement a classical lecture in order to enable deeper processing of information over a longer period of time, consequently resulting in enhanced learning performance.

Wikis are a website technology for mass collaborative authoring. Today, wikis are increasingly used for educational purposes. Basically, the most important asset of wikis is free and easy access for end users: everybody can contribute, comment and edit -- following the principles of Universal access. Consequently, wikis are ideally suited for collaborative learning and a number of studies reported a great success of wikis in terms of active participation, collaboration, and a rapidly growing content. However, the wikis success in education was often linked either to direct incentives or even pressure. This paper strongly argues that this contradicts the original intentions of wikis and, furthermore, weakens the psycho-pedagogical impact. A study is presented which focuses on investigating the success of wikis in higher education, when students are neither enforced to contribute nor directly rewarded similar to the principles of Wikipedia. Amazingly, the results show that, in total, none of the N= 287 students created new articles or edited existing ones during a whole semester. It is concluded that the use of Wiki-Systems in educational settings is much more complicated, and it needs more time to develop a kind of "give-and-take" generation.
