Television and education: A review of research

Summary The existing research on television of interest to educators was analyzed and found to be grouped into four general categories: (a) studies of the general social effects of television, (b) content analyses, (c) studies of the educational effects of television, and (d) technical studies. Studies in each of these four categories were reviewed and generalizations drawn from them. No attempt was made to review related research that is, no doubt, applicable to the problems of television. For example, the vast amount of research information developed in the audio-visual field during the past 30 years was not touched. Future investigators will find that the existing television research and the existing audio-visual research provide only a sketch map of the field of audio-visual communication. To use these important instruments wisely, and this is particularly true of television, it is necessary that we know and understand much more. This is the challenge for future research. To the knowledge of the editor, this is the first comprebensive review of educational television research to be published. The organizing of the research into four categories—general social effects, content analyses, educational effects, and technical problems—the rather detailed reviewing of the results, and the drawing of general conclusions should greatly aid the educator in understanding the unique contributions of educational television. An attempt will be made in future issues of Audio-Visual Communication Review to supplement this review of research by regularly publishing, in “Research Abstracts,” reviews of the most recent television studies. Dr. James D. Finn is Associate Professor of Education and Chairman of the Audio-Visual Education Department, University of Southern California. This paper was originally prepared at the request of the California State Department of Education for inclusion in theBrochure of Background Materials: Educational Television for the Governor’s Conference on Educational Television, held in Sacramento, California, December 15–16, 1952. It was necessary to develop the material in a very short time, and the writer wishes to express his indebtedness to F. Dean McClusky and May V. Seagoe of the University of California, Los Angeles, and to Lester F. Beck and Nicholas Rose, his colleagues at the University of Southern California, as well as to several of his graduate students for helping in locating copies of the studies reviewed.     

Immune disorders and dyslexia

The Geschwind-Behan-Galaburda hypothesis of cerebral lateralization postulates an association between immune disorders and learning disabilities. So far, the empirical evidence for such a relationship has been ambiguous. The present study is an attempt to investigate the hypothesis in a population where all the individuals were affected by immune disorders. Thus, 29 students in a special school for asthmatic children (total number of students in the school: 32) were investigated. A number of reading tests with special focus on word decoding were administered. The parents filled in a detailed questionnaire on the prevalence of reading difficulties and immune disorders among the other family members. The proportion of students with reading problems — especially phonological problems — was much higher than would be expected in a normal population. Among the family members we also found an elevated incidence of both reading problems and immune disorders. A cautious interpreptation of these findings leads to tentative and partial support of the Geschwind-Behan-Galaburda hypothesis.     

Teacher-center and school-based models of collegiality and professional development: Case studies of the teachers’ resource center and the Aga Khan school system in Karachi, Pakistan

Based on two recent teacher development efforts in Pakistan, this chapter examines efforts to promote teacher collegiality within these initiatives. The chapter first describes relevant contextual differences among schools in Karachi and summarizes the history of the two projects within this context. It then analyzes similarities and differences across these two projects in how they dealt with collegiality and professional development. While participants in both projects made progress in ameliorating extreme forms of teacher isolation and authoritarian relationships, they also discovered that balancing increased collegiality within a hierarchy of responsibilities and rewards is a difficult and elusive goal.     

Education and conflict: Essay review

This review essay looks at three recent publications in the emerging field of ‘education and conflict’ and explores an apparent gap between theory and practice in the field. Recent works by educationalists Lynn Davies, ‘Education and conflict: complexity and chaos’ (2004) and Tony Gallagher, ‘Education in divided societies (2004)’ are contrasted with the World Bank's 2005 ‘Reshaping the future: education and postconflict reconstruction’, and similarities between the publications are highlighted. Davies’ work uses complexity theory to illuminate the relationships between education and conflict and to establish an argument for ‘complex-adaptive schools’, which would use conflict positively to engage students in the creation of peaceful communities. Gallagher, using a number of well-developed case studies, examines the way education systems have been structured to respond to and operate in divided societies, concluding that classroom agency and flexibility are crucial. The calls, by Davies and Gallagher, for educational re-creation are explored in contrast to the World Bank's publication, which offers best practice lessons to support post-conflict educational reconstruction. The article probes these differences and points to areas where the practitioner-directed Bank publication and the more academic works do and do not intersect, attempting to indicate areas where bridges may be built.     

The Role of Mathematics Teachers' Content Knowledge in their Teaching: A Framework for Research applied to a Study of Student Teachers

The authors develop and explain a framework toguide research on the relationship betweenmathematics teachers' knowledge of content andtheir teaching. The framework istwo-dimensional. The dimensions are (a) theelements of teaching and (b) the processes ofteaching in which knowledge of content is ofconsequence. The interplay between the elementsof teaching and the processes of teaching isdiscussed theoretically, consideringconnections to existing literature about therole of teachers' subject matter knowledge.Three vignettes from the authors' work withpre-service secondary mathematics teachersinvestigate further the relationship betweencontent knowledge and effective mathematicsteaching. The vignettes also serve toillustrate the complexity of investigationsinto this relationship. Direction is offeredfor use of the framework in future research.
