Best and worst dressed web courses: Strutting into the 21st century in comfort and style

Web courses are constructed as the answer to fiscal crises evoked by neo‐liberal restructuring. They are also touted as an anarchist exemplar of ‘de‐schooling’ as envisaged by Ivan IIlich. The trouble is, some courses are vastly under‐dressed and merely attempt to display a face‐to‐face course on‐line. At the other extreme are those laced with links, animation and more than enough glitter and glam to make Liberace wince. In this study the authors employed a 43‐item coding schedule to examine the accessibility, opportunities for interaction and attractiveness of 127 courses on the web. Interrelationships between the 43 variables and issues pertaining to accessibility, interaction and attractiveness were identified with the aid of SPSS. Exemplary web courses were then distinguished from mediocre web courses. In our view, Madonna exemplifies qualities that should be incorporated into web courses. After examining 127 sites the Madonna award for the ‘best‐dressed’ site went to a University of Wisconsin History course. The ‘worst‐dressed’ award went to a Social Foundations of Education course at a USA State University which exuded glitter but lacked substance. Reasons for these decisions are elaborated. (The word, course, used here, describes what some systems call a unit of study.)     

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.     

Isokinetic Leg Flexion and Extension Strength of Elite Adolescent Female Track and Field Athletes

Abstract

Sixty-two elite adolescent (age: 16.39 ± 1.62 yrs) female track and field athletes volunteered to be measured isokinetically for peak torque of the leg flexors and extensors. The sample included 16 throwers, 11 jumpers, 12 middle-distance runners (> 400 m), and 23 sprinters. A Cybex II isokinetic dynamometer was used to measure dominant leg strength at 180°/sec. One-way ANOVA revealed significant between group differences for absolute flexion and extension (Nm), extension/body weight (Nm/Kg), and extension/lean body weight (Nm/Kg). Scheffe post-hoc comparisons showed that, for absolute leg extension strength, throwers were stronger than middle-distance runners (by 54.4%), sprinters (35.6%), and jumpers (23.6%). For absolute leg flexion movements, throwers were stronger than middle distance runners (37.4%) and sprinters (32.1%). Jumpers had greater extension peak torque values than middle-distance runners relative to body weight (14.0%), and throwers were stronger than middle-distance runners for extension/lean body weight (14.9%)). No other comparisons were significant. However, when strength was expressed relative to body weight or lean body weight, there were few differences between events for flexion or extension. Given that absolute strength scores were correlated with body weight and lean body weight, peak torque/body weight or peak torque/lean body weight may be more sensitive than absolute values as indicators of underlying factors (such as training status or fiber type composition) responsible for the differences in muscular strength between groups.     

Yearly Changes in the Body Composition and Muscular Strength of High School Wrestlers

Abstract

The purpose of this investigation was to determine the yearly changes in body composition as well as absolute and relative isokinetic forearm flexion and extension strength of high school wrestlers. Evaluations of body composition (underwater weighing) were performed on 27 high school wrestlers prior to three consecutive seasons. In addition, isokinetic forearm flexion and extension strength values at 180°/s (Cybex II) were available for 20 of the subjects. The mean ages at the times of laboratory testing were 15.5 (± .5), 16.5 (± .5), and 17.5 (± .5) years. Repeated measures ANOVA or ANCOVA with Tukey post-hoc comparisons were used to locate significant (p<.05) differences across age for height, body weight, relative fat, body density, fat weight, fat-free weight, absolute muscular strength, and muscular strength covaried for body weight and fat-free weight. There were yearly increases in all variables except fat weight, forearm flexion covaried for fat-free weight and forearm extension covaried for fat-free weight. The results of this study indicated that the improved wrestling performance and the increase in weight classification which normally occurs during high school are, in part, a function of yearly changes in body composition and muscular strength.     

Substance use: A life skills perspective

The paper proposes a life skills perspective for understanding substance use, in which generative and context based competences and control strategies are central. Within that framework, reasons for substance use, general goal related competence, and specific strategies used to control substance use were examined for 360 young people (144 males, 216 females) aged 18–20 years. Relationships were established between frequency of use of alcohol, tobacco, and other drugs and participants’ self reported knowledge of methods and effects of use, as well as of how much use was made of knowledge of effects in social situations. Participants also answered short tests on actual knowledge of effects and results on these were related to the extent of use reported. Finally perceptions of the best ways to learn about the effects of using these substances were related to patterns of reported use. The results supported the application of the life skills perspective to the domain of substance use in six areas; goal orientation; perceived competence; control over one’s actions; contextual competence; personality traits; and utilisation of knowledge. Educational strategies to develop this perspective were suggested.     

Synthesizing soft systems methodology and human performance technology

Human performance technology (HPT), like other concepts, models, and frameworks that we use to describe the world in which we live and the way we organize ourselves to accomplish valuable activities, is built from paradigms that were fresh and relevant at the time it was conceived and from the fields of study from which it grew. However, when the frameworks used by practitioners grow out of similar paradigms, important things can be missed when designing solutions in performance environments simply because of their practical limitations and exclusion of issues that may warrant our attention. This article looks at the paradigms most commonly used to explain performance environments, both within HPT and by those from other fields. From this a synthesized approach to solving perceived problems in performance environments is provided that introduces Soft Systems Methodology to the HPT practitioner, an approach built on premises very different from those commonly utilized in HPT frameworks.
