Visualizations have become more complex in recent years so that users need to learn how to use these systems. Onboarding systems can help users to learn how to interact with a visualization efficiently. Simple tutorials are often not sufficient. There are still open questions on how to design such onboarding systems. So far, a few usability…

Diagrams are succinct, visual representations of real-world or mathematical objects that serve to communicate properties of the objects and facilitate problem solving. This study explored perceptions of mathematics teachers in Singapore, who are heads of mathematics departments in their respective schools, related to diagrams and their use in the…

Building from the evidence-based learning progression in geometric reasoning from the RMFII project, this paper presents data from students' solutions to three problems in geometry and measurement situations to identify key components needed to nurture reasoning. To show emerging analytical reasoning students must coordinate multiple pieces of…

Prototypes of an annotated scientific text visualizer were designed, developed, and deployed. This pedagogic tool is designed to help undergraduates draft short research articles that conform to the generic expectations of their discourse community. This online tool enables users to discover and explore the language features present in short…

Cross-disciplinary skills are today's key skills for media informatics students to gain employment after graduation. However, such problem-based learning projects almost never take place due to organizational struggles. The authors suggest Scrum, a framework that is increasingly used in software engineering, as a solution for the challenges. Scrum…

Understanding key concepts in molecular biology requires reasoning about molecular processes that are not directly observable and, as such, presents a challenge to students and teachers. We ask whether novel interactive physical models and activities can help students understand key processes in viral replication. Our 3D tangible models are…

This article argues for a shift in how researchers discuss and examine students' uses of representations during their calculus problem solving. An extension of Zazkis, Dubinsky, and Dautermann's (1996) Visualization/Analysis-framework to include physical modes of reasoning is proposed. An example that details how transitions between visual,…

This study was designed for two major goals, which are to describe students' mental models about atom concept from 6th to 8th grade and to compare students' mental models with visual representations of atom in textbooks. Qualitative and quantitative data were collected with 4 open-ended questions including drawings which were quantified using the…

This research team has developed a learning trajectory on 3D visualization for elementary children. This paper focuses on the interchange among the three Spatial Operational Capacity framework representations, namely, 3D models, 2D conventional diagrams, and semiotic abstract representations, and the critical role of a dynamic computer interface…

The paper looks into visualisation in learning mathematics from three perspectives: It starts from a discussion what it takes to make a sign, an inscription on the blackboard, on paper or on a computer screen to an image. Here we will look into the question of "similarity" and point to the possibility of having different perspectives on the same…

This paper discusses issues of representation in the use of scientific visualizations, specifically those used for biomedical applications, and the implications of those issues to interface design. Topics addressed include the benefits of research into the generation of virtual simulation (virtual reality) and the importance of realism. (Contains…

Discusses visualization of legal information using a tool for temporal information called "LifeLines." Explores ways "LifeLines" could aid in viewing the links between original case and direct and indirect case histories. Uses the case of Apple Computer, Inc. versus Microsoft Corporation and Hewlett Packard Company to…

Based in a stream of community-based health promotion activities rather than a fixed framework of hypothesis testing, the study described in this paper tried to solve the problem of the one-sided communication between Japanese health care providers and receivers by visualizing health-related feelings and concepts for both parties involved in the…

This paper describes a faculty resource team in the Bradley University (Illinois) Department of Industrial Engineering that works with student project teams in an effort to improve their visualization and oral presentation skills. Students use state of the art technology to develop and display their visuals. In addition to technology, students are…

An internal cognitive variable--mental imagery representation--was studied using a set of three information-processing strategies under external stimulus visual display conditions for various learning levels. The copy strategy provided verbal and visual dual-coding and required formation of a vivid mental image. The relational strategy combined…
