However, the cases where learners have been actively involved as cocreators of knowledge visualization aids are limited. Furthermore, employing knowledge visualization for teaching and learning in high-school science have been proposed but empirical evidence of the effect on knowledge transfer is limited. The purpose of this study is to report on the knowledge transfer effect of applying usability-based knowledge visualization guidelines. A design-based research methodology guided by pragmatism was applied. The data capturing methods include a questionnaire-based survey, interviews and observations. The results suggest that the use of knowledge visualization can support knowledge transfer and the students' learning experience in secondary school education, but more research is required to confirm this. The contribution of this paper is to add to the emerging discourse on the use of knowledge visualization for teaching and learning, and to report on how knowledge visualization guidelines can be used in practice.

We investigated the effect of a newly developed PV tool to teach tracing to first-year programming students at a South-African university. The tool takes the form of an interactive computerbased tutorial that teaches students how to draw variable diagrams (VD). All students registered for the introductory C++ module, received the tutorial with their study material and could use it to help answer assignment questions. To determine the effect of using the tutorial, students did an assignment for which they could use the tutorial and completed a questionnaire. Through the questionnaire we acquired biographical data, found out how students used the tutorial and also how they experienced using it. We then correlated these data statistically with their assignment marks. We found that time spent using the tutorial, programming experience and certain biographical properties contributed to higher marks. Drawing their own VDs to understand and debug programs also contributed to better marks.

Kendall et al reason that agent development to date has been done independently, leading to problems such as could assist in a more wide-spread use of mobile agents. The purpose of this literature survey is to gain a knowledge base of the current practices in programming mobile agents in order to formulate such a set of guidelines for creating/programming and using a mobile agent efficiently.
