mLearn4web Visualization : Identifying appropriate ways of visualizing data collected by mobile learning activities for an educational setting

Sammanfattning: mLearn4web is a web-based framework aiming to support the creation of mobile applications within the field of mobile learning. The framework consists of three main parts; an authoring tool, automatically deployed mobile applications and a visualization tool. The visualization tool was implemented as part of this thesis’ work. The focus of this thesis was to identify visual representations for data collected in mLearn4web activities and to implement these representations in a new visualization tool. The work has had a design-based research approach and was conducted together with teachers as a part of an iterative design process. The work was initiated by a literature review and a study of previous mLearn4web use. A questionnaire was then sent to teachers, where they were asked to rate different visual representations. This was the basis for the development of the visualization tool. Three workshops involving teachers were conducted throughout the process, finally resulting in a functional visualization tool and a set of visual representations that were found appropriate by teachers. Evaluations with experienced teachers show that the visual representations proposed and implemented can be appropriate in an educational setting. To further validate them the tool and its visual representations need to be tested in real-life settings, and should ideally also include students.
