Interactive multimedia problem-based learning for

enhancing pre-service teachers’ self-efficacy beliefs

about teaching with computers: Design, development

and evaluation

A Dissertation submitted by

Abstract

Research has suggested that, despite support through policy and resource provision, information and communications technologies (ICTs) have made little impact on the practice of education and that limited teacher preparation for the use of ICTs represents a partial explanation. The purpose of this study was to investigate what form of professional education might be effective in preparing pre-service teachers to integrate ICTs into their teaching. Self-efficacy beliefs about teaching with computers were identified as a potentially significant source of influence on teachers’ use of ICTs for teaching. It was proposed that interactive multimedia using a problem-based learning design (IMM-PBL) should be an effective tool for increasing self-efficacy. Principles for the design of IMM-PBL were derived from the relevant literature.

An IMM-PBL package was designed and developed for delivery in a web browser format using content relevant to the integration of ICTs into teaching. Interviews with and sample responses prepared by computer-using teachers provided the basis for ensuring the relevance of content.

The completed materials were evaluated in use with a group of 24 final year pre-service teachers in a Queensland university. Participants in the trials reported that the materials were engaging and assisted their learning about integrating computers in their teaching. A statistically significant increase in self-efficacy for teaching with computers was found for users who had initially low self-efficacy for teaching with computers.

Acknowledgments

My sincere thanks go to my principal supervisor Professor Perc Marland who provided advice and encouragement from the inception of the study. Despite setbacks and changes in direction, Perc seemed never to doubt that it could be successfully completed. His expansive knowledge and experience of teacher education and associated research provided inspiration at many stages of the journey.

I am grateful also to my associate supervisors. Professor Jeff Bailey first aroused my interest in self-efficacy theory and provided invaluable assistance in the formative first two years of the study. Following Jeff’s appointment elsewhere, Professor David Ross provided practical advice and support during the design and development of the multimedia package and in the final stages of evaluation.

Multimedia development demands a diverse range of talents as is evident in the acknowledgments printed on the cover of the Integrating Information Technology into Teaching CD-ROM. The names listed therein are too numerous to repeat here, except to acknowledge the contribution of my colleague, Dr Ian Gibson. Ian was instrumental in the success of our joint application for funding from the National Priority (Reserve) Fund Teacher Education Initiative, without which the multimedia might never have been developed. It was his experience with problem-based learning that led to its adoption as a design framework and he shared responsibility for the educational design of the materials. His advice and encouragement, although at a distance for the final stages of development, contributed substantially to the shape of the final product.

Thanks also to Dr Tony Rickards who adjusted the teaching of his classes to accommodate the evaluation of the multimedia materials and to the students in his and other classes who, whether they worked with the materials or not, willingly completed questionnaires and other instruments.

I acknowledge also the encouragement and occasional assistance of numerous other colleagues at USQ and elsewhere. I am especially grateful to Dr Ashley Plank, Dr Don Rice and Dr Andrew Sturman who provided advice about statistical procedures.
