Of gateways and gatekeepers: Language,education and mobility in francophone Africa

Over the past 15 years, a range of alternative education programs have been launched in Burkina Faso. The programs have been developed primarily by international or national NGOs, within a supportive policy space provided by the national government. They aim to respond to the widely recognized inadequacy of the French-language écoles classiques to provide a meaningful primary education experience for most Burkinabè children.     

Reread-adapt and answer-comprehend intervention with Deaf and hard of hearing readers: effect on fluency and reading achievement

The researchers investigated the effect of the Reread-Adapt and Answer-Comprehend intervention (Therrien, Gormley, & Kubina, 2006) on the reading fluency and achievement of d/Deaf and hard of hearing elementary-level students. Children in the third, fifth, and sixth grades at a state school for d/Deaf and hard of hearing students received a fluency intervention that was supplemental to their regular reading instruction. Significant improvement was found on a generalized measure of reading fluency after intervention. Though the researchers found no significant improvement in performance on a generalized measure of comprehension after intervention, the students demonstrated consistently good comprehension on both literal and inferential questions during the intervention sessions. The findings support the importance of incorporating a comprehension monitoring strategy in fluency instruction.     

The impact of verbal capacity on theory of mind in deaf and hard of hearing children

Even when they have good language skills, many children with hearing loss lag several years behind hearing children in the ability to grasp beliefs of others. The researchers sought to determine whether this lag results from difficulty with the verbal demands of tasks or from conceptual delays. The researchers related children's performance on a nonverbal theory of mind task to their scores on verbal aptitude tests. Twelve French children (average age about 10 years) with severe to profound hearing loss and 12 French hearing children (average about 7 years) were evaluated. The children with hearing loss showed persistent difficulty with theory of mind tasks, even a nonverbal task, presenting results similar to those of hearing 6-year-olds. Also, the children with hearing loss showed a correlation between language level (lexical and morphosyntactic) and understanding of false beliefs. No such correlation was found in the hearing children.     

The ‘truth’ of academic development: how did it get to be about ‘teaching and learning’?

The nature of academic development in contemporary universities has been a recent focus in the literature. Highlighting the diversity of practices that exist under its name, ‘academic development’ has been described by some as an ambiguous project and a fragmented field, while others suggest a more coherent project, pointing out a near universal concern with, in particular, teaching and learning. Through an exploration of the practices of the first academic developers in New Zealand, and a consideration of the particular institutions in which they were operating, this article draws on the work of Foucault to consider the modalities of power that were available to them. This exploration is used as a basis from which to consider the systems of truth that began to emerge as a result of the early appointees' practice, in particular their original and enduring concern with teaching and learning as objects of knowledge.     

Portrayal of the History of the Photoelectric Effect in Laboratory Instructions

The literature on the pedagogical aspects of the photoelectric effect as used in the undergraduate student laboratory shows that little research has been done in this area. Our current study is an analysis of the instructions in 38, electronically published laboratory manuals for the photoelectric effect. The analyses were based on history and philosophy of science criteria that we had developed for evaluating the presentation of the photoelectric effect in introductory, university-physics textbooks. The results show that writers of laboratory instructions do not pay sufficient attention to the relevant background for the photoelectric effect. In our study, none of the instructions achieved a score of excellent, only 5% were scored as satisfactory, and only 7% mentioned the various aspects contained in our criteria. These results for our analysis of laboratory instructions are significantly less favorable than those achieved for physics textbooks in our previous study. Based on our work, we recommend that several historical aspects be included in all laboratory instructions for the photoelectric effect.     

Heart Rate Holter Monitoring of 6- and 7-Year Old Children with Insulin Dependent Diabetes Mellitus Cardiovascular and Short Term Metabolic Response to Exercise: A Pilot Study

Abstract

This study examined whether gender and/or training were related to the exercise-induced changes in plasma concentrations of growth hormone (GH), prolactin (PRL), triiodothyronine (T₃), and thyroxine (T₄). Twenty subjects (male and female 10-km runners; untrained males and females) ran on a treadmill for 30 win at 80% of previously determined maximum heart rate. Blood samples were taken through an indwelling catheter from an antecubital vein at ?30, 0, +15, +30 min of the test and 30 min of recovery. Reded temperature rose significantly (p < .01) at +15 and +30 min with concomitant rise in GH concentration, but PRL, T₃, and T₄ were not affected by the exercise. We concluded that a 30-min run at 80% of maximum heart rate is associated with higher concentrations of GH but not of PRL, T₃, and T₄ Neither training state nor gender affected the aforementioned results.     

Cardiac Structure and Function in Weight Trainers,Runners, and Runner/Weight Trainers

Abstract

The purpose of this study was to describe and compare cardiac structure and function in adult male weight trainers, runners, and those who do both activities. Subjects had actively participated in the various training programs for the previous five years. Age ranged from 28.4 to 31.3 years in the three groups. Echocardiography was used to assess selected heart diameters, volumes, indices of contractility, and thicknesses, while VO₂ max and percent body fat were measured using standard methods. Heart structure and function were expressed in absolute terms and relative to total body weight. An alpha level of .05 was used in all comparisons. Results indicated the runners demonstrated significantly greater relative LVID_d, LVID_s, and LVPW than the weight trainers. The runner/weight trainers possessed significantly greater relative LVID_d, LVID_s, LVPW, IVS, and LVEDV than the weight trainers. No significant differences, absolute or relative, existed between the runner and runner/weight trainer groups in any of the myocardial structure and function variables. It was concluded that men who run or run and weight train have similar structural and functional characteristics of the heart and possess greater relative internal diameter and left ventricular wall thickness than men who only weight train.     

The Association between Physical Activity Behavior and Commonly Reported Barriers in a Worksite Population

Recent experiments on the ski simulator produced ambiguous results and raised unanswered questions concerning the true nature of “novice” behavior and the occurrence of behavioral changes during learning. The aim of the present experiment was to analyze the evolving behavior of three beginners during six practice sessions on a ski simulator. The position of the apparatus platform was recorded as time series and used for constructing dynamical models, including stiffness and damping functions. The results showed that novices tended to exploit a Rayleigh damping behavior during the first trials and then transition toward a van der Pol damping. These results replicate previous observations by Nourrit, Delignières, Caillou, Deschamps, and Lauriot (2003) and suggest the transition to the expert behavior could arise early in practice, when the task is of moderate difficulty. The discussion focuses on the properties of the observed learning dynamics and proposes a global conceptualization for acquiring complex motor skills.     

Development of an Attitude Inventory to Measure the Attitude of High School Girls toward Physical Education as a Career for Women

Abstract

An attitude inventory was developed for the purpose of determining the attitudes of high school girls toward physical education as a career for women. Likert's technique of scale construction was selected for use in this study. Statements covering aspects of the physical education profession as they apply to women were prepared according to recommended criteria. Each statement was subjected to statistical analysis in order to eliminate those which were ambiguous or which had poor discriminatory power. Following the use of the split-half method for determining reliability, the statements were divided into two equivalent forms of the inventory.
