STEM instruction often uses visual representations. To benefit from these, students need to understand how representations show domain-relevant concepts. Yet, this is difficult for students. Prior research shows that physical representations (objects that students manipulate by hand) and virtual representations (objects on a computer screen that…

Abstract electronics concepts are difficult to develop because the phenomena of interest cannot be readily observed. Visualisation skills support learning about electronics and can be applied at different levels of representation and understanding (observable, symbolic and abstract). Providing learners with opportunities to make transitions…

Garrett, Lauretta – Journal of Developmental Education, 2013
Adult developmental mathematics students often work under great pressure to complete the mathematics sequences designed to help them achieve success (Bryk & Treisman, 2010). Results of a teaching experiment demonstrate how the ability to reason can be impeded by flaws in students' mental representations of mathematics. The earnestness of the…

Psycharis, Giorgos; Latsi, Maria; Kynigos, Chronis – International Journal for Technology in Mathematics Education, 2009
This paper reports on a case-study design experiment in the domain of fraction as number-measure. We designed and implemented a set of exploratory tasks concerning comparison and ordering of fractions as well as operations with fractions. Two groups of 12-year-old students worked collaboratively using paper and pencil as well as a specially…

Peer reviewedRam, Ashwin, Ed.; Nersessian, Nancy J., Ed.; Keil, Frank C., Ed. – Journal of the Learning Sciences, 1997
This special issue includes four articles that address issues concerning conceptual change. Topics include analogical reasoning and a case study of Johannes Kepler; conceptual change and wine expertise; the role of extreme case reasoning in instruction for conceptual change; and dynamic science assessment: a new approach for investigating…

Knight, Colin, Gasevic, Dragan; Richards, Griff – Educational Technology & Society, 2006
The paper describes an ontology-based framework for bridging learning design and learning object content. In present solutions, researchers have proposed conceptual models and developed tools for both of those subjects, but without detailed discussions of how they can be used together. In this paper we advocate the use of ontologies to explicitly…
