Abstract

In this study, we examined the perceptions of physical education (PE) teachers' feedback patterns with female and male high school students (n = 325). Eight physical education teachers (4 females and 4 males) were involved. We examined (a) whether teachers' feedback was perceived differently by boys and girls, and how the sex of the teacher influenced these perceptions, and (b) the effects of types of feedback (praise, no response-successful, encouragement, technical information, criticism, no response-unsuccessful, and teacher's invested time) on students' perceived competence, effort, enjoyment, and their PE performance. A multivariate analysis revealed an interaction between teacher and student gender on perceptions of teacher feedback. Hierarchical regression analyses highlighted that the perceived feedback significantly predicted students' perceptions of competence (ΔR 2 = 0.088), effort (ΔR 2 = 0.119), enjoyment (ΔR 2 = 0.085), and their PE performance (ΔR 2 = 0.039) after accounting for the gender of the students and teachers and the students' initial PE performance. The perceptions of praise and teachers' invested time were positively linked with the dependent variables, whereas encouragement and technical information and criticism were negatively linked. The findings are discussed in terms of teaching effectiveness and gender equity.  相似文献

The purpose of this study was to quantify and compare kinematic, temporal, and kinetic characteristics of American and Korean professional pitchers in order to investigate differences in pitching mechanics, performance, and injury risks among two different cultures and populations of baseball pitchers. Eleven American and eight Korean healthy professional baseball pitchers threw multiple fastball pitches off an indoor throwing mound positioned at regulation distance from home plate. A Motion Analysis three‐dimensional automatic digitizing system was used to collect 200 Hz video data from four electronically synchronized cameras. Twenty kinematic, six temporal, and 11 kinetic variables were analyzed at lead foot contact, during the arm cocking and arm acceleration phases, at ball release, and during the arm deceleration phase. A radar gun was used to quantify ball velocity. At lead foot contact, the American pitchers had significantly greater horizontal abduction of the throwing shoulder, while Korean pitchers exhibited significantly greater abduction and external rotation of the throwing shoulder. During arm cocking, the American pitchers displayed significantly greater maximum shoulder external rotation and maximum pelvis angular velocity. At the instant of ball release, the American pitchers had significantly greater forward trunk tilt and ball velocity and significantly less knee flexion, which help explain why the American pitchers had 10% greater ball velocity compared to the Korean pitchers. The American pitchers had significantly greater maximum shoulder internal rotation torque and maximum elbow varus torque during arm cocking, significantly greater elbow flexion torque during arm acceleration, and significantly greater shoulder and elbow proximal forces during arm deceleration. While greater shoulder and elbow forces and torques generated in the American pitchers helped generate greater ball velocity for the American group, these greater kinetics may predispose this group to a higher risk of shoulder and elbow injuries.  相似文献

The purpose of this study was to propose and test a motivational model of persistence in science education. The model posits that science teachers’ support of students’ autonomy positively influences students’ self-perceptions of autonomy and competence. These self-perceptions, in turn, have a positive impact on students’ self-determined motivation toward science which leads to their intentions to pursue science education and eventually work in a scientific domain. This model was tested with high school students (n=728). Results from univariate analyses of variance and from structural equation modeling analyses (with LISREL) were found to support the proposed model. In addition, a direct link was obtained between perceptions of competence and intentions to pursue a science education, indicating that higher levels of perceived competence predicted higher levels of persistence intentions. The present findings support Self-Determination Theory and open the way to future research from a motivational approach in this area.  相似文献

Abstract

Avant la colonisation de Madagascar par la France en 1896, la plupart des enfants malgaches scolarisés avaient fréquenté des écoles dirigées par des missions protestantes. La langue d’enseignement était la langue malgache, une langue écrite, développée avec l’aide de missionnaires britanniques à partir de 1820. Elle était celle du groupe clanico-politique dominant. La colonisation imposa la langue française. Le pouvoir colonial avait considéré la langue comme un instrument important dans la politique d’assimilation et la création d’élites qui pourraient servir son projet. Mais l’administration coloniale dans les pays colonisés influençait fortement l’exécution de la politique éducative. Madagascar est d’ailleurs un cas pertinent dans ce sens à cause de l’existence et le statut de la langue écrite Malgache. La politique assimilatrice dominante n’a pas empêché des désaccords au sein de l’administration coloniale sur la place de la langue malgache dans l’éducation. L’argument majeur était que cette langue renforcera le groupe ethnique Merina et alimentera davantage le nationalisme malgache au détriment de l’assimilation. Depuis l’Indépendance en 1960, la politique linguistique a évolué selon les régimes politiques. Les perspectives théoriques dans le domaine de la “literacy” (des aptitudes à lire et à écrire vu comme une pratique sociale) décrivent celle-ci comme une pratique sociale et un instrument de pouvoir. Sa diffusion générale a été associée avec un développement démocratique, mais aussi avec l’oppression. L’article montre comment la politique des langues d’enseignement à Madagascar s’est basée sur des arguments politique et pédagogique dans des contextes différents.  相似文献

This longitudinal case study examines whether a school-based training scheme that brings together different categories of teacher educators (university supervisors and cooperating teachers) engenders true collective training activity and, if so, whether this collective work contributes to pre-service teacher education. The scheme grew out of a recent French reform policy. The study is based on an original theoretical conception of teacher education that borrows postulates from a theory of learning and collective action (Wittgenstein 1996). Illustrated by excerpts from post-lesson meetings and self-confrontation interviews, the results suggest that the training scheme does not always lead to collective training activity. The difficulties are notably due to disagreement between the educators about attributing meaning to the pre-service teacher’s classroom activity, which hampers professional development. On this basis, proposals are made to contribute to an effective and authentically shared supervision process and to reposition training activity at the heart of the processes of pre-service teacher professional development.  相似文献

In reaction to Elbers' paper, several comments are made concerning the unit of analysis used to observe children's cognitive activity, the nature of the competence assessed, and the role of the task, or the object of knowledge, in which the child and the adult interact. It is argued that the testing situation is a social event in which the adult and the child interact on a specific object and negotiate a common interpretation of the task and the situation. From this perspective, the testing situation appears to be a learning situation in which new knowledge is acquired.  相似文献

As a teaching method, tutorials are fundamental to university education, and are underpinned by the following goals: to accompany students; to help them establish a clear training pathway; and to promote their academic achievement. Our proposal aims to introduce psychological aspects into the Tutorial Action Plan (TAP) which, while often left unattended, are closely related to academic achievement. Our objective is to identify the relation between the academic commitment of pre-service teachers (preschool education, primary education and double degree students) at the UB and stress and coping skills, academic motivation, achievement and self-efficacy, as well as the opinions of students and tutors on the resources used during TAP and potential improvements to it. This is a transversal prospective exploratory study, applying the following questionnaires: Academic commitment (UWESS-9); Perceived Stress Scale (PSS); Self-efficacy (NGSE); Motivation (MSLQ); and two ad hoc online questionnaires. In conclusion, we hope that the results of this study will help us reformulate the TAP of said degree programmes, improving personalized attention and the quality of the student tutorial system, which is one of the standards used to assess universities.  相似文献

10 and 11-year old children were trained to improve their argumentative abilities. Tests were performed on two experimental groups to find out the effects of (1) a didactic sequence of seven lesson with oral exercises, and (2) a co-operative oral debate. To allow us to determine the improvements, the children had to produce three argumentative constrained texts (Alpha-Omega), before and after each phase of training. We compare the results with two control classes to try to determine the quality of transfer between the teaching periods. The qualitative analysis of the texts allows us to identify certain linguistic indicators of the underlying cognitive processes. The results show an effect of training only for the 11-year-old writers. In the 10-year-old children, no clear transfer from oral training was observed. With or without training, ten-year-old writers seem to have difficulties organising the text and managing multiple constraints when writing. In contrast, at 11, the subjects reorganise their activity without taking account of their narrative abilities. The vast majority produce better balanced argumentative texts. However their texts tend to be justificatory rather than negotiated. At the same time, the Alpha-Omega task carries very strong constraints which interfere with cognitive processes during on-line production.  相似文献
