This paper presents the results of a literature search and review focused on the integration of digital games into educational processes, specifically in primary schools. It briefly analyses around 78 papers reporting research carried out in a range of different countries and with a variety of educational objectives. The study confirms the increasing wealth of scientific studies dealing with ga...

The present paper proposes a novel way to unify Rough Set Theory and Formal Concept Analysis. Our method stems from results insights developed in the algebraic theory of modal logic, is based on idea that Pawlak’s original approximation spaces can be seen as special instances enriched formal contexts, i.e. relational structures formal; contexts

These notes discuss formal iz ing contexts as first class objects. The basic relation is ist(c,p). It asserts that the pro-position ρ is true in the context c. The most important formulas relate the propositions true in different contexts. Introducing contexts as formal objects wil l permit axiomatizations in limited contexts to be expanded to transcend the original limitations. This seems nece...

This study examines variation in moral judgment level as measured by the Defining Issues Test 2 (DIT-2; J. R. Rest & D. Narvaez, 1998), based on individual demographic information and educational contexts. Individual DIT-2 scores and demographic information were obtained from the archived data sets housed at the Center for the Study of Ethical Development. The information on educational context...

L-bonds represent relationships between fuzzy formal contexts. We study these intercontextual structures w.r.t. antitone Galois connections in fuzzy setting. Furthermore, we define direct -product and -product of two formal fuzzy contexts and show conditions under which a fuzzy bond can be obtained as an intent of the product. This extents our previous work on isotone fuzzy bonds.

Interaction analysis within online educational contexts based on collaborative learning strategies requires a multidimensional model taking into account social, emotional and cognitive components. Starting from the assumption that only through correlation of these three dimensions it’s possible to capture and understand the generative processes of learning in CSCL, this research is aimed at stu...
