Interaction styles and expert social influence

An experiment examined the conditions under which an expert source induces less competent targets to adopt a point of view contradicting their own in a context of information transmission. In a 2×2 factorial design participants (N=86) were either 1st year or 4th year university students, and the style of the message delivered by the epistemic authority was either authoritarian or democratic. The main dependent variable was the degree to which participants went beyond mere approval and adopted the contradicting information. The principal finding was that the contradicting information was adopted more readily by the 1st year participants confronted with an authoritarian as compared to a democratic expert source. Students in their 4th year were more influenced by a democratic source than the 1st year students. These results partially confirm the correspondence hypothesis according to which appropriation of knowledge from an expert source is favoured when the characteristics of the influence relations match fundamental expectations that individuals have concerning this relationship, these expectations varying as a function of the stage they have reached in their university education.     

Best Not Forget Lesbian,Gay, Bisexual,and Transgender Themed Children's Literature: A Teacher's Reflections of a More Inclusive Multicultural Education and Literature Program

For many years, educational practitioners have been implementing multicultural literature about African-American, Asian, and Latino families. Teachers have also presented literature about great leaders, such as Martin Luther King Jr. and Helen Keller. However, the same cannot be said about literature depicting lesbian, gay, bisexual, and transgender (LGBT) families and heroes. In this article, the author's experience of teaching a multicultural literature program and students' responses to LGBT-themed literature are presented and discussed.

Culture and equality in education

The advent of comprehensive education implies a search for a common culture, or a common treatment of culture, across the whole school population. This article reviews the present stage in this search, attempting to define a suitable treatment of culture by secondary schools. The history of schools’ treatment of cultural sources is briefly invoked, particularly the differences in treatment found in grammar and secondary modern schools. Purportedly progressive attitudes to ‘formal’ or ‘high’ culture are analysed and found to be too simplistic. Traditional education is shown not to have genuinely served its own’ supposed cultural aims, whilst progressives’ rejection to those aims is shown to be inadequate as a reaction to what traditional education actually did rather than claimed to do. It is proposed that a more engaged approach to formal culture, involving critical receptivity, is appropriate for all pupils, and would also require the nourishment of a more receptive attitude to pupils’ own creativity.

Since we have liberated the term ‘culture’ from meaning merely a rarified level of works of art, it has become so all‐embracing as to be almost unmanageable. Influenced by anthropology, we now tend to think of culture as extending to the most casual level of value and idea by which we live our daily lives. It even includes our most informal language habits.

The difficulty, of course, with such an all‐embracing notion is that it makes the subject almost impossible to talk about. Criteria of quality , and currency are blurred. Part of the same confusion is that the education system, formerly seen as the custodian of ‘culture’, now has no name for the special resources of knowledge which are ‐‐ or used to be ‐‐ its particular responsibility.

I will use culture here to mean those public works or activities which represent man to himself and are value laden. Thus literature, psychology, history, philosophy, politics, law, economics and sociology would all be included. They might have scientific elements but they still convey normative images of man.

If the concept of culture itself, even as so defined, has a blunt edge, we must discriminate elements within it in order to make the area susceptible to discussion. To get a picture of how schools, traditionally, have mediated culture, we must distinguish at least five broad elements:

1. formal, by which is meant that part in which academic and professional institutions specialize;

2. informal, meaning relatively spontaneous and non‐centralized activities, including ordinary conversation;

3. mass culture, such as films, television, popular music, advertising;

4. avant‐garde culture, arising out of a sense of crisis in the formal culture; and

5. ethnic, other than that which coincides with the content of previous categories.

These are pretty crude categories, but they are a little better than such common divisions as ‘high/low’, ‘popular/serious’ and ‘traditional/contemporary’, and they permit some analysis of relationships between different elements within our culture as a whole.     

The effect of sex and localised fatigue on triceps surae musculoarticular stiffness

Purpose: The main purpose of this study was to investigate the influence of fatigue on musculoarticular stiffness (MAS) of the ankle joint across sexes. Methods: Twenty-seven males and 26 females participated in the study. After baseline assessment of MAS and related variables, localised fatigue was induced in triceps surae using the standing heel-rise test during which the subjects were instructed to lift and drop the heel at a frequency of 0.5?Hz. When subjects were unable to continue due to exhaustion the test was terminated and another MAS test was performed soon after. Results: Significant higher triceps surae MAS was found in men compared to women (p?p??1 and from 14.5 to 13.9?KN?m^?1 in men and women, respectively. Percentage changes revealed, however, that in relative terms the changes in all the variables evaluated were similar (p?>?.01) between sexes, with MAS less than 5%. Conclusion: Despite the sex-related differences at baseline, fatigue seems to affect biomechanical properties of the ankle joint similarly in men and women.     

Acute intraocular pressure changes during isometric exercise and recovery: The influence of exercise type and intensity,and participant´s sex

ABSTRACT

We assessed the intraocular pressure (IOP) behaviour during a 1-minute period of isometric physical effort and the immediate 1-minute of recovery in the mid-thigh clean pull and squat exercises at three different intensities. Twenty physically active individuals performed the isometric mid-thigh clean pull and squat exercises at three intensities (0% [low-intensity], 25% [medium-intensity] and 50% [high-intensity] of the maximum isometric force). IOP was semi-continuously measured by rebound tonometry. There was a statistically significant effect of exercise intensity on IOP (p < 0.001, ?_p² = 0.416), observing that IOP increments were positively associated with exercise intensity. The mid-thigh clean pull and squat exercises did not demonstrate differences (p = 0.510), and also, no differences were observed between men and women (p = 0.683). The IOP changes during the isometric physical effort showed a positive linear behaviour in all conditions (r = 0.70 to 0.96). IOP returned to baseline levels after 8 seconds of recovery. Our data showed a progressive and instantaneous IOP increment during isometric exercise, which was positively associated with exercise intensity. IOP changes were independent on the type of exercise and participant´s sex. After exercise, IOP rapidly (≈ 8 seconds) returned to baseline levels.     

Challenges to Cognitive Bases for an Especial Motor Skill at the Regulation Baseball Pitching Distance

We tested expert baseball pitchers for evidence of especial skills at the regulation pitching distance. Seven college pitchers threw indoors to a target placed at 60.5 feet (18.44 m) and four closer and four further distances away. Accuracy at the regulation distance was significantly better than predicted by regression on the nonregulation distances (p < .02), indicating an especial skill effect emerged despite the absence of normal contextual cues. Self-efficacy data failed to support confidence as a mediating factor in especial skill effect. We concluded that cognitive theories fail to fully account for the patterns of observed data, and therefore theoretical explanations of the especial skills must address noncognitive aspects of motor learning and control.     

Developing Children's Understanding of Fractions: An Intervention Study

Fractions constitute a stumbling block in mathematics education. To improve children's understanding of fractions, we designed an intervention based on learning‐by‐doing activities, which focused on the representation of the magnitude of fractions. Participants were 292 Grade 4 and 5 children. Half of the classes received experimental instruction, while the other half pursued their usual lessons. For 10 weeks, they played five different games using cards representing fractions (e.g., Memory and Blackjack). Wooden disks helped them represent and manipulate fractions while playing games. Our results showed an improvement in the conceptual understanding of fractions. The findings confirmed that the usual practice in teaching fractions is largely based on procedural knowledge and provides only minimal opportunities for children to conceptualize the meaning and magnitude of fractional notations. Furthermore, our results demonstrate that a short intervention inducing children to manipulate, compare, and evaluate fractions improves their ability to associate fractional notations with numerical magnitude.
