Teaching & Learning with Digital Resources – The Problem Valuable digital resources for teaching and learning have grown exponentially over the past several years. n Custom digital libraries hold these collections of digital resources n Lack of tools that provide the flexibility and responsiveness required to support critical and creative thinking with digital resources. n

Educational Foundations Constructivism – Students learn best when they are actively engaged in constructing their knowledge – in structuring and restructuring information n Individual Differences – Cognitive differences among people influence their approach to learning. n

Educational Foundations Learning takes place by the assimilation of new concepts and prepositions into existing concept prepositional frameworks held by the learner n Meaningful learning occurs when it is relatable to the learner’s prior knowledge. n Concept maps are useful tools to bring about meaningful learning. n

Concept Maps in Education Tools for organizing and representing knowledge. n Concepts are semantic units of learning n Include concepts usually enclosed in circles or boxes of some type and relationships between concepts indicated by a connecting line between the two. n Words on the line specify the relationship between the two n

VUE - A Solution n A visual environment for structuring, presenting and sharing digital information that allows faculty and students to integrate digital resources into teaching and learning A way to access different kinds of digital resources stored in different digital repositories Has tools for teachers and learner to navigate through these resources to support critical and creative thinking.

Leveraging Open Standards It leverages open and extensible development platform of OKI and FEDORA digital repository to facilitate collaborative open source development.

Goals for VUE 1. In support of teaching, provide faculty with a flexible, visual tool for semantically structuring and creating pathways through digital materials in a manner most consistent with the ideas and concepts that they must communicate to their students. 2. In support of active learning, provide students with a flexible tool for manipulating and extending existing instructional presentations (concept/content maps) in support of personal reflection on course topics as well as support for the creation and communication of new, personally meaningful concept/content maps. 3. Extend the value of FEDORA-based digital libraries and their collections by providing a flexible, visual tool for viewing and organizing digital content in pursuit of individual learning and research goals. 4. Leverage OKI technical standards to enable the sharing, distribution and integration of this new educational tool in educational environments and systems beyond Tufts University.
