Expectancy and halo effects as a result of artificially induced teacher bias

This investigation examined the effects of deviancy labels on teachers' expectations of child behavior and their ability to evaluate child behavior objectively. One hundred elementary school teachers were randomly assigned to one of four label groups. Each group dealt with one label (emotionally disturbed, learning disabled, mentally retarded, normal), and each group participated in two separate treatment phases. During Phase I teachers identified behaviors they expected to be displayed by hypothetical children characteristic of the label condition. They were asked to complete a referral form for either a hypothetical normal, mentally retarded, learning disabled, or emotionally disturbed child. During Phase II, each group saw the same videotape of a normal fourth grade boy and completed a second referral form based on the behaviors displayed during this presentation. Experimental procedures were identical for the four groups, except each group was told the child was a member of a different category.Results indicated that teachers hold negative expectancies toward children categorized with a deviancy label and maintain expectancies even when confronted with normal behavior, behavior inconsistent with the stated label. Maintenance of this bias is sufficient to cause teachers to misinterpret actual child behavior, resulting in a halo effect. Results further indicated that the label of educable mentally retarded generated a greater degree of negative bias than did the labels learning disabled or emotionally disturbed, although all three deviancy labels produced negative expectancies and halo effects significantly different from those found under control conditions.     

Relations Among Oral Reading Fluency,Silent Reading Fluency,and Reading Comprehension: A Latent Variable Study of First-Grade Readers

In the present study, we examined oral and silent reading fluency and their relations with reading comprehension. In a series of structural equation models with latent variables using data from 316 first-grade students, (a) silent and oral reading fluency were found to be related yet distinct forms of reading fluency, (b) silent reading fluency predicted reading comprehension better for skilled readers than for average readers, (c) list reading fluency predicted reading comprehension better for average readers than for skilled readers, and (d) listening comprehension predicted reading comprehension better for skilled readers than for average readers.     

International trends in health science librarianship Part 9: the UK – Scotland and Wales

This is the 9th in a series of articles exploring international trends in health science librarianship. The previous article in this series looked at Northern Ireland and the Republic of Ireland. In this issue the focus is Scotland and Wales. There will be three or four more articles this year tracking trends in the Far East, Africa, South Asia and the Middle East. JM     

Body Composition of Olympic Speed Skating Candidates

Abstract

The purpose of this investigation was to quantify the body composition of speed skaters who were candidates for the 1980 United States Olympic Team. Subjects were 19 males between 16 and 27 years of age. Most subjects had just completed three months of intensive dry-land training. Seven skinfold fat, 11 circumference, and seven diameter sites were measured. Body density was determined by underwater weighing. Study of the speed skaters (mean ± standard deviation) gave the following results: height, 176 ± 8 cm; body weight, 69.6 ± 7.0 kg; body density, 1.081 ± 0.006 g/ml; and relative fat, 7.6 ± 2.6%. The eight speed skaters who were selected for the Olympic Team were significantly older, taller, and heavier in total body weight and fat free weight (FFW) than the non-Olympians. Thus, years of training and greater FFW may help differentiate international caliber male speed skaters. Data on Olympic speed skating candidates from 1968 showed them to be of similar age (20.1 yr) and height (176 cm), but greater in body weight (73.9 kg). Relative fat was not determined but the body mass index (Wt/ht²) showed that the present speed skaters may be leaner (24.0 vs 22.2). These differences in body composition were thought to be, in part, a result of the more rigorous training program currently used by speed skaters. The body composition of the speed skaters was also compared to that of other athletic groups.     

The impact of international students on measured learning and standards in Australian higher education

International students, who are also often from non-English language speaking backgrounds (NESB students), are an important source of revenue for Australian universities. Yet little large-scale evidence exists about their performance once they arrive. Do these students perform worse than other students in Australian undergraduate classrooms? What happens to other students’ performance when these students are added to classrooms? I provide new empirical evidence on these questions using recent administrative panel data from the business schools of two Australian Technology Network universities. Results show strong and highly statistically significant main effects and spillover effects, raising concerns about the integration of international NESB students into the Australian tertiary environment.     

Aversive and aggression-promoting properties of urine from dominant and subordinate male mice

The urine of individual dominant and subordinate male mice was tested for aversive and aggression-promoting properties using open-field and aggression tests The results indicate the presence of (1) an aversive factor in male mouse urine which discourages investigation of an area marked with such urine and (2) an aggression-promoting factor. Dominant male urine proved far more effective in both respects than subordinate urine, the latter having similar effects to water. The results are discussed in terms of androgen output and possible territorial functions.     

Political culture and education in advanced industrial societies: West Germany and the United States

This paper sets out a theoretical framework for the understanding of education and political culture in industrial societies. The framework represents a response to the systems approach to this subject. The framework we propose treats political alienation as a normal outcome of the incompatibility between egalitarian goals and social inequalities in democratic systems. The framework is then applied to the role of education in the United States. We view education as a means by which norms later productive of political alienation are initially distributed throughout democratic systems. Further, we view the school's current predicament in America as a manifestation of its role in the creation of alienation. We then turn to Germany and speculate about the sources of recent democratic support in that political culture, despite the alienating tendencies predicted by our model. We single out factors of tradition, religion, economics, and educational organization as means of understanding changes in the political culture of that society. An absence of relevant data prevents us from applying our model of alienation in a fully comparative way to the German situation. We conclude by considering the effects of short-run political events on our model, and by speculating about the resurgence of alienation in German political culture once German schools, like American schools, more fully play the role of disseminating egalitarian norms in a socially inegalitarian system.

Zusammenfassung Diese Studie stellt einen Rahmen für das Verständnis des Bildungswesens und der politischen Kultur in Industrieländern auf, der als Antwort auf den Systems-Ansatz zu diesem Thema gedacht ist. Dieser Rahmen behandelt politische Entfremdung als normales Ergebnis der Unvereinbarkeit von egalitären Zielen und sozialen Ungleichheiten in demokratischen Systemen. Zunächst wird er auf die Rolle des Bildungswesens in den USA angewandt. Bildung wird als ein Mittel gesehen, dem gesamten demokratischen System Normen zu eigen zu machen, die später zu politischer Entfremdung führen. Auch die gegenwärtigen Schwierigkeiten im amerikanischen Schulwesen werden auf seine Rolle als Erzeuger von Entfremdung zurückgeführt. Dann geht die Untersuchung auf die Bundesrepublik Deutschland über und stellt Überlegungen an über die Ursachen der deutlichen Zunahme demokratischer Gesinnung, trotz der von dem hier vorgeschlagenen Modell vorausgesetzten Entfremdungstendenzen. Tradition, religiöse und wirtschaftliche Faktoren sowie die Organisation des deutschen Bildungswesens werden zur Erklärung der Veränderungen in der politischen Kultur dieser Gesellschaft herangezogen. Mangels relevanter Daten kann das Entfremdungsmodell nicht in völlig vergleichbarer Weise auf die deutsche Situation angewandt werden. Abschliessend werden die Auswirkungen kurzfristiger politischer Ereignisse auf das Modell in Betracht gezogen sowie die Möglichkeit, dass auch in der deutschen politischen Kultur wieder stärkere Entfremdung eintreten wird, sobald die deutschen Schulen, ähnlich den amerikanischen, in vollerem Umfang die Rolle der Verbreitung egalitärer Normen in einem sozial nicht-egalitären Gesellschaftssystem spielen.

Résumé Cet article présente und cadre théorique de travail permettant une meilleure compréhension de l'éducation et de la culture politique dans les sociétés industrielles. Ce cadre est une réponse à l'approche systématique de ce sujet. Le cadre que nous proposons envisage l'aliénation politique comme un aboutissement normal de l'incompatibilité entre buts égalitaires et inégalités sociales dans des systèmes démocratiques. Le cadre est ensuite appliqué au rôle de l'éducation aux Etats Unis. Nous regardons l'éducation comme un moyen par lequel les normes qui, ultérieurement vont produire l'aliénation politique, sont distribuées initialement, dans les systèmes démocratiques. Nous examinons ensuite l'école: nous voyons sa situation critique actuelle en Amérique comme une manifestation de son rôle dans la création de l'aliénation. Nous nous tournons ensuite vers l'Allemagne et nous formons des conjectures sur les sources du récent soutien démocratique à cette culture politique, en dépit des tendances à l'aliénation prédites par notre modèle. Nous choisissons des facteurs de tradition, de religion, d'économie et d'organisation éducative comme étant des moyens permettant de comprendre les changements dans la culture politique de cette société. Une absence de données pertinentes relatives à ce sujet nous empêche d'appliquer notre modèle d'aliénation d'une façon parfaitement comparative à la situation en Allemagne. Nous concluons en examinant les effets des évènements politiques pendant une brève période sur notre modèle et en faisant quelques réflexions sur la résurgence de l'aliénation dans la culture politique allemande, lorsque les écoles allemandes, comme les écoles américaines, jouent plus complètement le rôle de disséminatrices de normes égalitaires dans un système socialement inégalitaire.
