Chang Rundgren, Shu-Nu; Yao, Bao-Jun – Asia-Pacific Forum on Science Learning and Teaching, 2014
Based on the importance and widely use of visualization in science, this article has a three-fold aim related to the terms of visualization, representation and model that in recent years have been introduced to the field of science education without clear differentiation. Firstly, the three terms are discussed with examples to provide a common…

Oviatt, Sharon L.; Cohen, Adrienne O. – Journal of Science Education and Technology, 2010
From a theoretical viewpoint, educational interfaces that facilitate communicative actions involving representations central to a domain can maximize students' effort associated with constructing new schemas. In addition, interfaces that minimize working memory demands due to the interface per se, for example by mimicking existing non-digital work…

Clark, Douglas B.; Sampson, Victor – Journal of Research in Science Teaching, 2008
The national science standards, along with prominent researchers, call for increased focus on scientific argumentation in the classroom. Over the past decade, researchers have developed sophisticated online science learning environments to support these opportunities for scientific argumentation. Assessing the quality of dialogic argumentation,…

Solaz-Portoles, Joan Josep; Lopez, Vicent Sanjose – Asia-Pacific Forum on Science Learning and Teaching, 2007
In this paper we focus on some of the findings of the science education research community in the area of representations and problem solving. Problem solving depends on the construction and manipulation of mental models (internal representations) in the mind. A large knowledge base (declarative, procedural, strategic, situational, and schematic…

Chi, Michelene T. H. – Journal of the Learning Sciences, 2005
This article offers a plausible domain-general explanation for why some concepts of processes are resistant to instructional remediation although other, apparently similar concepts are more easily understood. The explanation assumes that processes may differ in ontological ways: that some processes (such as the apparent flow in diffusion of dye in…
