Corradi, David; Clarebout, Geraldine; Elen, Jan – Journal of Science Education and Technology, 2015
Previous research on multiple external representations (MER) indicates that sequencing representations (compared with presenting them as a whole) can, in some cases, increase conceptual understanding if there is interference between internal and external representations. We tested this mechanism by sequencing different combinations of scientific…

Corradi, David M. J.; Elen, Jan; Schraepen, Beno; Clarebout, Geraldine – International Journal of Science Education, 2014
When learning with abstract and scientific multiple external representations (MERs), low prior knowledge learners are said to have difficulties in using these MERs to achieve conceptual understanding. Yet little is known about what these limitations precisely entail. In order to understand this, we presented 101 learners with low prior knowledge…

Corradi, David; Elen, Jan; Clarebout, Geraldine – Journal of Science Education and Technology, 2012
Theories on learning with Multiple External Representations (MER) claim that low prior knowledge learners in science have difficulties using MER, which are seen as necessary to achieve a conceptual understanding. In two experiments, we analyze the mechanisms underlying the learning of chemistry with MER. Our first experiment focuses on how MER can…
