Research description

Interactive Tracing and Graphical Annotation in Pen-based e-learning (I-TRACE)

Objectives

The project aims at gaining experience in the pedagogical, organizational, design and development issues involved in introducing advanced graphical interaction techniques in e-learning environments, and at developing a set of resources at the European level, that can be of reference for using, either within an ODL framework or in the classroom, technology allowing graphical input and early forms of multimodal interaction, both in stand-alone and collaborative learning settings.

The specific objectives of the project are:

Understanding the added educational value of the use of interactive graphics within an integrated platform such as the Tablet PC

Understanding its potential for meeting the individual learners' preferences and styles

Field Evaluation (studies of practice) in various educational contexts : medical education, engineering and design education, both in different cultural settings, and both within pedagogical models that emphasize individual practice or collaborative learning on the web, impact on on-line mentoring

Studying the integration (the use) of interactive graphics with comprehensive assessment methods

Pointing out the relationships of this practice with the Learning Object technology, providing a specification for its integration in managed learning environments (MLEs) or Learning content management systems (LCMS) within current EC standards

Developing a model for the design of learning environments and educational materials that can exploit the potential of these novel interaction modalities

Building a web site to share the guidelines and results coming from the above activities, and provide a space for keeping sharing related experiences among teachers and educators, and professionals involved in ODL.
