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.

A Deliberate Practice Approach to Teaching Phylogenetic Analysis

One goal of postsecondary education is to assist students in developing expert-level understanding. Previous attempts to encourage expert-level understanding of phylogenetic analysis in college science classrooms have largely focused on isolated, or “one-shot,” in-class activities. Using a deliberate practice instructional approach, we designed a set of five assignments for a 300-level plant systematics course that incrementally introduces the concepts and skills used in phylogenetic analysis. In our assignments, students learned the process of constructing phylogenetic trees through a series of increasingly difficult tasks; thus, skill development served as a framework for building content knowledge. We present results from 5 yr of final exam scores, pre- and postconcept assessments, and student surveys to assess the impact of our new pedagogical materials on student performance related to constructing and interpreting phylogenetic trees. Students improved in their ability to interpret relationships within trees and improved in several aspects related to between-tree comparisons and tree construction skills. Student feedback indicated that most students believed our approach prepared them to engage in tree construction and gave them confidence in their abilities. Overall, our data confirm that instructional approaches implementing deliberate practice address student misconceptions, improve student experiences, and foster deeper understanding of difficult scientific concepts.     

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.     

Cross‐Country Heterogeneity in Students’ Reporting Behavior: The Use of the Anchoring Vignette Method

Self‐reports are an indispensable source of information in education research but they are often affected by heterogeneity in reporting behavior. Failing to correct for this heterogeneity can lead to invalid comparisons across groups. The researchers use the parametric anchoring vignette method to correct for cross‐country incomparability of students’ reports on teacher's classroom management. Their analysis is based on the data from the Programme for International Student Assessment 2012. The results show significant variation in implicit standards across countries. Correlations between countries’ average teacher classroom management levels and external variables like students test scores and public expenditure per pupil change substantially after vignette adjustment. The researchers conclude that the anchoring vignettes method shows potential to enhance the comparability of self‐reported measures in education.     

Sight versus Sound: The Differential Impact of Mediated Spectator Response in Sport Broadcasts

Despite the research examining various production aspects of broadcast sport, scholars have generally overlooked a ubiquitous sonic component of broadcasts—spectators’ aural response (i.e., crowd noise). Such cues can act as a heuristic to influence perceptions of competition, particularly in the absence of visuals. Using continuous response measurement, this experiment demonstrates how mediated spectator response in the form of crowd noise yields enhanced perceptions of the exciting nature of broadcast sport, although the effect is diminished in televised sports. Implications are suggested for contemporary sport consumption, where aural cues can draw attention to game events in multi-screen viewing scenarios.     

Using micro-sensor data to quantify macro kinematics of classical cross-country skiing during on-snow training

Abstract

Micro-sensors were used to quantify macro kinematics of classical cross-country skiing techniques and measure cycle rates and cycle lengths during on-snow training. Data were collected from seven national level participants skiing at two submaximal intensities while wearing a micro-sensor unit (MinimaxX^?). Algorithms were developed identifying double poling (DP), diagonal striding (DS), kick-double poling (KDP), tucking (Tuck), and turning (Turn). Technique duration (T-time), cycle rates, and cycle counts were compared to video-derived data to assess system accuracy. There was good reliability between micro-sensor and video calculated cycle rates for DP, DS, and KDP, with small mean differences (Mdiff% = ?0.2 ± 3.2, ?1.5 ± 2.2 and ?1.4 ± 6.2) and trivial to small effect sizes (ES = 0.20, 0.30 and 0.13). Very strong correlations were observed for DP, DS, and KDP for T-time (r = 0.87–0.99) and cycle count (r = 0.87–0.99), while mean values were under-reported by the micro-sensor. Incorrect Turn detection was a major factor in technique cycle misclassification. Data presented highlight the potential of automated ski technique classification in cross-country skiing research. With further refinement, this approach will allow many applied questions associated with pacing, fatigue, technique selection and power output during training and competition to be answered.     

Discursive Power and Creativity in Inter-Professional Work

This paper discusses how discursive power and creativity are found to be inter-related in a context not traditionally associated with creative work; the operating theatre of a hospital. Here, it is proposed that creativity relies on socio-cultural factors emphasizing the practical nature of creativity, and highlighting the fact that a large part of our creativity connects with our everyday social life and practices. We assume that power is exercised in an embedded manner in everyday work and continuously reproduced and redefined between the social actors. The data utilized here derive from a collective ethnographic research project focusing on surgical workplace learning and professional identity. Observational data and field notes from work situations in operating theatres are utilized. The paper illustrates the manifestations of discursive power through three selected example episodes. Our findings show the intertwined nature of power and creativity in OT work practices. The power relations do not function only to restrict collaboration but can also promote collective creativity. Collective creativity in inter-professional work is exercise of agency in the workplace, especially with the actors with less power. Shared creative solutions in the work practices are achieved in a shared organizational culture in which power becomes discursively internalised and institutionalised. We argue that new insights will be brought up in the area of workplace learning and professional development by taking into account the institutionalized collective acts in working communities. The study supports the need for further development of inter-professional collaboration and learning in health care work organizations.
