The participants will be asked to reflect weekly about their use of the trackers. It will enable participants to enter their experiences with the biometric data, like relevance of difference sensor data, lifestyle adaptations (like e.g. more sleep), special situations (e.g. hike, changes in heart rate during activity) and how these experiences lead to specific searches and actions in the web and/or in their real social network. Students will be able to publish different formats of reflections as text, hyperlinks to health related web pages and images. The quality of the materials, collected and published within the ePortfolio tool, has been shown to improve during the previously conducted pilot work during the development of this tool. The created ePortfolio is expected to provide a fundamental platform for meaningful and sustainable interaction between the students and the teacher in the continuous construction of knowledge towards any undergraduate programmes' intended learning outcomes. It is expected to enhance the metacognition of own learning through repeated reflection. This will be assessed as suggested previously. Students have access to all their reflections and can retrieve past events of their reflective ePortfolio, described above.
