Meaning : multiple representations, computation & instruction
… others conflicting. We can develop models from multiple perspectives, applying a range of concepts to problems in the field. The trick is never to be tied to a single way of seeing and solving problems. Too heavy an anchor can keep our minds from wandering freely to novel ideas and approaches. …

Investigating introductory science students’ knowledge of multiple representations using technology
… understand how to measure students’ use of multiple representations in introductory science courses by expanding the possibilities of a variable representation assessment (VRA). The VRA is a computer-based assessment originally designed to measure general chemistry students’ use of …

Enhancing teachers' knowledge for using multiple representations in teaching chemistry in Nigerian senior secondary schools
… pedagogical knowledge and beliefs about using multiple representations in chemistry education through a professional learning program. Participating teachers attended a series of professional learning workshops on how to construct, interpret and use multiple representations to teach chemistry …

Use of Multiple Representations to Explore Students’ Understandings of Covalent and Ionic Bonding as Measured by the Bonding Representations Inventory
… general chemistry curriculum. Teachers use multiple representations to communicate the concepts of bonding, including Lewis Structures, formulas, spacefilling models, and 3D manipulatives. As students learn to interpret these multiple representations, they may develop misconceptions that can …

Flexible Learning in the Periodic System With Multiple Representations: The Design of a Hypertext for Learning Complex Concepts in Chemistry
This dissertation argues that the design of technological artifacts such as educational software is a complex process involving a continuous dialogue between theory and practice; between constraints and tradeoffs; between designers and their materials; between designers and the users/learners. It …

Using Multiple Coordinated Representations in a Technology -Intensive Setting to Teach Linear Functions at the College Level
… (1) the spreadsheet approach emphasizing multiple representations enhanced achievement in linear functions, and (2) more positive attitudes toward some aspects of mathematics could be expected as a consequence of using multiple representations.

Structure Mediated Use of Local-Global Duality in Image and Video Processing
An image can have multiple representations, each of which has its own advantages and disadvantages from the perspective of image processing operations. This thesis investigates how to combine multiple representations with efficient optimization techniques so as to gather together their combined …

Learning to Represent Mathematics: The Negotiation of Meanings of Mathematical Symbols in First Grade
… errors and confusion by increasing their use of multiple representations, more often than prior to them. Teachers especially responded to errors with reference to written symbols, and they responded to confusion with concrete manipulatives. Students referenced visual forms at a low rate overall …

Landscapes of Imagination: A Critical Analysis of Art Textbooks
… synthesis and higher level thinking processes, multiple representations of knowledge, and the aesthetic features of the textbooks. Four secondary art textbooks were analyzed, and a sample chapter was presented showing a design for a high school art textbook that was highly imaginative and …

Representations of Place: Perspectives From Seasonal Homeowners, Local Residents, and Mass Media
… a deeper understanding of place by incorporating multiple representations of place. Place research is an area of study that begs for new perspectives, new theories, and new methodologies. Place is more than a geographically determined space; it is a socially constructed phenomenon that continually …

A qualitative study of problematic reasonings of undergraduate electrical engineering students in Continuous Time Signals and Systems courses
… content are related to content areas of Signal Representations and Operations, Frequency Analysis, and System Analysis. The identified reasonings can be further classified under three main learning challenges, namely i) accommodation; ii) translation of a signal to its multiple representations …

Imagina : a cognitive abstraction approach to sketch-based image retrieval
… instead of the matching of global measures. Multiple representations, focusing on shape and color, are used for every region. The matches of individual regions are combined using a saliency metric that accounts for differences in the distributions of metrics. Region matching along with …
