Zusammenfassung
We argue that current selection methods and comparison approaches of tools for learning purposes do not fit with the concept of e-learning 2.0 and Web 2.0 applications for creating personal learning environments. Available comparison methods being mainly as black-and-white check lists hinder to see the properties of various Web 2.0 applications. We propose a theoretical framework for designing a support tool for learners as well as for facilitators in order to facilitate the choice of learning/teaching tools from heterogeneous technological landscapes. Our theoretical framework is based on soft ontological approach enabling to compare systems and tools from multidimensional perspectives taking into account users best practices. We focus on elements of learning activities mediated by technology with respect to the concept of affordances and activity theory in combination of Alexander's pattern approach and IMS LD case descriptions.
