Multimedia and Online Video Case Studies for Preservice Teacher Preparation

Case studies have been used successfully as a part of teacher education. There are many possibilities in extending the impact of case studies through the use of technology. Video and the Internet could enable demonstration of more examples, dissemination beyond the walls of the classroom, and discussion between geographically dispersed preservice teachers. Several projects are now investigating the possible ways that technology might enhance or extend text case studies. After exploring four existing products, four essential elements for video case studies are proposed. As video case studies move to the Internet, additional issues arise and these are also explored.     

With the eyes of others: an ethnography of an academic office

The author raises questions about ethnographic methodology through exploring the implications of using observations produced by his colleagues about his office as data for his research. This process blurred the boundaries between researcher, method and the object and subject of research. It meets some criteria for ethnography and not others, and does not evidence clear definitional boundaries for any sub-genre such as autoethnography or collaborative authoethnography. Besides raising definitional challenges and the blurring of roles in research, the study also illustrates how the methodology revealed tensions over collegial trust, boundaries and privacy. The author's colleagues exposed aspects of the author's identity that were opaque and even invisible to the author. The author accordingly raises questions about the locus of ethical concern. Thus, issues of roles, definition, trust, boundaries, privacy and method were entwined.

CD-ROM talking books: what do they promise?

This study describes one teacher's use of multimedia, specifically CD-ROM talking books, in the classroom. The goal of the investigation was to reveal and analyse how a primary (Grade 3) teacher integrated CD-ROM books into her curriculum. Issues emerging from the study included how features of the software interact with features of classrooms, how patterns of instruction are affected by the infusion of technology, and how students interact with the software, and each other, while reading the CD- ROM books
