Gobert, Janice D.; Sao Pedro, Michael; Raziuddin, Juelaila; Baker, Ryan S. – Journal of the Learning Sciences, 2013
We present a method for assessing science inquiry performance, specifically for the inquiry skill of designing and conducting experiments, using educational data mining on students' log data from online microworlds in the Inq-ITS system (Inquiry Intelligent Tutoring System; www.inq-its.org). In our approach, we use a 2-step process: First we use…

Parnafes, Orit – Journal of the Learning Sciences, 2007
This article concerns the development of conceptual understanding of a physical phenomenon through the use of computational representations. It examines how students make sense of and interpret computational representations, and how their understanding of the represented physical phenomenon develops in this process. Eight studies were conducted,…

Suthers, Daniel D.; Hundhausen, Christopher D. – Journal of the Learning Sciences, 2003
Evaluates the influence of tools for constructing representations of models on collaborative learning. Pairs of participants worked with either a graph, matrix, or text while investigating complex science and public health problems. Results indicate that representational notations can have significant effects on learners' interactions and may…

Penner, David E.; Schauble, Leona; Lehrer, Richard – Journal of the Learning Sciences, 1998
A design context for developing children's understanding of the natural world via designing, building, testing, and evaluation of models was studied. Children were asked to design models of human elbows which provided opportunities to develop their understanding of the relations between mathematics and science through the construction and…

Murray, Tom – Journal of the Learning Sciences, 1998
Describes tools for authoring all aspects of a knowledge-based tutor system: domain model, teaching strategies, student model, and learning environment. Discusses a number of design issues and design tradeoffs that are involved in building intelligent tutoring systems (ITS). (Author/CCM)

Bell, Benjamin – Journal of the Learning Sciences, 1998
Presents a prototype authoring tool for interactive educational software called Investigate and Decide Learning Environments (IDLE-Tool). Introduces IDLE-Tool as the task model around which the tool is based. A model of the authoring process called Guided Case Adaptation is offered as an approach to employing models and an exemplar to effectively…

Ritter, Steven; Blessing, Stephen B. – Journal of the Learning Sciences, 1998
Argues that a focus on building an authoring tool for a complete learning environment is misplaced. Analyzes the task of authoring a commercial educational system. Describes the Visual Translator, an authoring tool written specifically for this purpose. (Author/CCM)

Resnick, Mitchel; Wilensky, Uri – Journal of the Learning Sciences, 1998
Argues that role-playing activities can be a powerful tool in mathematics and science education, particularly in the new sciences of complexity (i.e., the study of complex systems). Two role-playing activities are described, each designed to help students develop better intuitions on how complex phenomena can arise from simple interactions, and…
