Teachers routinely make decisions regarding the best pedagogical methods for altering students' understandings about academic content. Such practices are at the root of teaching as persuasion, and have been shown to be related to academic achievement. Yet very little research has investigated the extent to which individuals learning to be teachers…

This study, the purpose of which is to determine an efficient instructional design for different levels of spatial abilities, investigates: (1) the main effects of visual treatments in simulation environments on comprehension and the transfer of chemistry knowledge and (2) the interaction effects of the visual treatments and the learners' spatial…

Previous research and development with cognitive tools has been limited by an inadequate conceptualization of the complexity underlying their nature and affordances for supporting learning and performance. This paper provides a new perspective on cognitive tools through the lens of the theories of distributed cognition and expertise. The learner,…

More and more educators and researchers use ICT-tools to support collaborative learning. Research has shown that, for collaborative learning to be more effective than individual learning, individual learners have to achieve a sufficiently common cognitive frame of reference, or common ground. This common ground does not appear by itself, but…

The aim of this paper is to study the online teaching styles of two teachers who each tutor a networked learning community (NLC), within the same workshop. The study is undertaking empirical work using a multi-method approach in order to triangulate and contextualise our findings and enrich our understanding of the teacher participation in these…

The study investigates immediate and delayed effects of different hypermedia glosses on incidental vocabulary learning and reading comprehension of advanced foreign language learners. Sixty-nine freshman TEFL students studying at a Turkish university were randomly assigned to three types of annotations: (a) definitions of words, (b) definitions…

In most mathematics textbooks, each set of practice problems is comprised almost entirely of problems corresponding to the immediately previous lesson. By contrast, in a small number of textbooks, the practice problems are systematically shuffled so that each practice set includes a variety of problems drawn from many previous lessons. The…
