Abstract
Does integration of visual and verbal knowledge during learning support deep understanding? Can robust learning be supported implicitly by representations that link relevant knowledge components in visual and verbal materials? The overall goal of this project is to gain a better understanding of 1) visual and verbal knowledge components in a problem-solving environment and, 2) how instructional support to promote connections between visual and verbal knowledge components can support the development of deep understanding. Ultimately, we are interested in coordination and integration processes in learning with visual and verbal knowledge components, and how these processes may support robust learning.
We are using the Geometry Cognitive Tutor as a research vehicle for our project. In geometry, visual information is represented pictorially in a problem diagram and verbal/symbolic information is represented in text that contains given and goal information as well as in conceptual rules/principles of geometry. The goal of the research described here is to determine if implicit instructional events that use visual cues to map between text and diagrams can support knowledge retention and transfer. These visual cues are instantiated in the Geometry Cognitive Tutor by using colored highlighting to connect textual references of geometric features in instructional hints to the visual depictions of those features in the geometry diagram (screen shots provided below, in the Independent Variables section). This in vivo study will take place April - June, 2007.

Interactive Communication as Support for Visual-Verbal Integration:
Our research is investigating multiple methods with which student learning can be supported by interactions with pictorial information during geometry learning. Our work also includes more a more explicit method for supporting student integration visual and verbal knowledge components. This method involves interactive support for students' elaborated explanations during geometry learning. Research investigating this explicit support is part of the Interactive Communication Cluster: LINK
