The presented research will employ a multi case methodology study to explicate the affordances of wearable trackers, as they emerge from the ten students using this technology. The study will constitute an inductive, hypotheses generating naturalistic inquiry, whose aim is to accumulate an understanding and propose recommendations relevant to the study context. It will focus on the larger picture, the whole picture, and begin with a search for understanding of the whole. The research findings will provide a broad picture of the events taking place in particular contexts, allowing readers to draw their own conclusions. The sample size of the presented study, conducted over 5 months with an exemplary group of 35 students across the four key areas, is sufficiently large for a multi case methodology study. The interview data will be collected by a research assistant and by the principal investigator. The questionnaire data will be collected by the research assistants. The data from the tracker (individual reflections and biometric data) will automatically be recorded into a database. Interview and questionnaire will take place at the University, 30 minutes for each interview, 20 minutes for each questionnaire (1 hours and 40 minutes for each participant). A consistency technique will be applied across the 35 cases to allow comparability. The adopted case study methodology is adequate for retrieving a well rooted set of arguments and recommendations related to the learning process performed by the 35 students during the intervention related to eHealth literacy.
