The study examined how biases in self-evaluations of math competence relate to achievement goals and progress in math achievement. It was expected that performance goals would be related to overestimation and mastery goals to accurate self-assessments. A sample of French high-school students completed a questionnaire measuring their math achievement goals and their perceived competence in math. Students’ math grades for the three trimesters of the school year were collected from school records. Bias in self-evaluations was computed by comparing students’ rating on the ‘perceived competence in math’ scale with their actual math achievement as measured by their second trimester math grades. Students were classified into one of three groups (over-raters, accurate raters, or under-raters) depending on whether their self-perceptions of competence in math were higher than, similar to, or lower than their relative math achievement in their class. As expected, overrating of one's performance was related to performance goals. Furthermore, the over-raters were the only group who progressed in their math achievement from Trimester 2 to 3. No relation was found between mastery goals and accurate self-assessment. 相似文献

To identify how a governance structure leads to ambidexterity at the cluster level, in terms of knowledge management, this study draws on the knowledge -based view of clusters and on ambidexterity literature, thereby exploring an ‘intermediated’ cluster model of ambidexterity. Our aim is to explore the governance structure’s role and priorities in terms of knowledge management, as well as the underlying operational actions and programmes implemented to achieve cluster ambidexterity. Qualitative research, based on interviews with members of two French clusters, reveals that their governance structure is a crucial intermediary organisation that supports cluster ambidexterity. The results emphasise the role of governance structures for two types of ambidexterity in small and medium-sized enterprise (SME) clusters: First, SMEs may specialise in exploitative or exploratory knowledge, and the governance structure provides the missing knowledge (intermediated specialised model). Second, cluster governance may help each firm become ambidextrous (intermediated dual model). This study outlines the specificities of the two models and their contingency factors, which offer interesting implications, especially for policymakers devoted to innovation and clusters. 相似文献

The importance of encouraging language skills in early childhood has been well documented. Educators who are responsible for
children in daycare services have many opportunities to use rich and stimulating educational practices that support language
acquisition. The purpose of this study was to assess the language-support practices used by 22 educators in ECE centers with
174 children (87 girls and 87 boys) aged 55.7 months on average (SD = 4.2). The Teacher Interaction and Language Rating Scale
developed by Girolametto et al. (Teacher interaction and language rating scale, Hanen Centre, Toronto, 2000) was translated and adapted for use in French. Analyses reveal the heterogeneity of language support provided to 4-year-old
children attending early childhood education centers in Québec (Canada). Results are discussed in relation to the importance
of the educational setting and specific training on language skill development provided to educators around promoting language
skills in children, a fundamental prerequisite for educational success. 相似文献

In this article, we explore one of the important peritextual features of picturebooks—the endpapers. In order to represent the rich diversity of form and function displayed by endpapers, we group examples along two dimensions: whether the endpapers are illustrated or unillustrated, and whether the front and back end papers are identical or dissimilar. Within the four categories delineated by these two dimensions, we further articulate the various roles that endpapers can play in the construction of meaning from picturebooks. We present quotations from young children that show how they use endpapers as resources for literary and aesthetic interpretation, and provide suggestions for the integration of talk about endpapers within classroom literature discussions.

This paper provides new empirical evidence on primary pupils’ views on school attendance in Wales at Key Stage 2. The research was conducted as part of the specific evidence commissioned by the Welsh Assembly Government (WAG) for the National Behaviour and Attendance Review (NBAR) in Wales which was chaired by the lead author. The findings indicate that nearly every child and young person who participated in the specially convened focus groups, in practically every setting, had a good awareness of the benefits of attending school regularly. They were all acutely aware of the potential consequences of non‐attendance both within their current setting and as it could potentially affect their later chances in life. They also understood the law regarding school attendance. They were clear about the attendance regulations within their own school settings. They were however, particularly concerned about bullying in all its forms, the use of supply teachers and “boring” teaching styles. Rewards for good attendance were generally appreciated. The implications of the findings are considered. This paper is the first of its kind to be undertaken in Wales and in the field of school attendance and opens up considerable possibilities for further research. 相似文献

This paper explores the determinants of the choice of UK universities by overseas undergraduate applicants. We use data on overseas applicants in Business Studies and Engineering from 2002 to 2007, to 97 UK universities. Estimating using a Hausman–Taylor model to control for the possible correlation between our explanatory variables and unobservable university-level effects, we find that the fees charged may influence the application decision of some students, but that any relationship between levels of fees and applications is non-linear. The quality of education provided is positively and significantly related to the number of applications. Proximity to London and the existing popularity of a university among home applicants, are also significant predictors of university applications. 相似文献

This paper presents an approximate analytical model of the dynamics of a tapered fly line during a standard overhead cast.
During casting, the line forms a nonlinear propagating wave that is frequently referred to as a ‘loop’ by fly casters. The
geometry of the loop is described by three distinct parts: a straight bottom segment (attached to a stationary fly rod), a
semi-circular segment that is propagating (i.e. the loop), and a straight top segment that is also propagating, (i.e. the
traveling line). A fly (particle) is attached at the end of the traveling line. A work-energy balance yields the velocity
of the fly as a function of the length of the traveling line. For a uniform fly line (level line), a closed-form solution
is found, while for a tapered fly line, the solution is obtained by quadrature. A critical loop diameter arises in the analysis,
and it determines whether the final velocity of the fly is greater or lesser than the initial velocity of the traveling line.
The analytical solutions are critically compared against numerical solutions of a general model for fly line dynamics that
relaxes many of the assumptions employed in the analytical model. The agreement between the two solutions remains close during
the loop propagation phase, provided a significant amount of fly line remains in the traveling line. However, as the traveling
line vanishes and the loop ‘turns over’, the two solutions diverge abruptly due to the many simplifying assumptions employed
in the analytical model. 相似文献

Waiter’s serve (WS) is a specific tennis serve posture frequently observed in young players, and commonly considered as a technical error by tennis coaches. However, biomechanical impact of WS is unknown. The aims of this study were to identify the potential consequences of WS in young elite players relating to performance and injury risk, and to explain the kinematic causes of WS. Serve of 18 male junior elite players (Top 10 national French ranking, aged 12–15 years) was captured with a 20 camera, 200?Hz VICON MX motion analysis system. Depending on their serve technique, the players were divided into two groups (WS versus Normal Serve [NS]) by experienced coaches. Injury data were collected for each player during a 12-month-period following the motion capture. Normalized peak kinetic values of the dominant arm were calculated using inverse dynamics. In order to explain WS posture, upper limb kinematics were calculated during the cocking and the acceleration phases of the serve. Shoulder internal rotation torque, wrist proximal and anterior forces (P?.05) and elbow varus torque (P?.01) were significantly higher in WS group, with no difference from NS group concerning serve velocity. Moreover, significant lower shoulder abduction and higher wrist extension (P?.05) were observed for WS players during the cocking phase. Even if no significant difference was found between groups concerning injuries, higher upper limb joint loads suggested WS could be considered as pathomechanical in young elite players and could lead to upper limb joint injuries. 相似文献

The purpose of this study was to evaluate the role of rotation axes during a tennis serve. A motion capture system was used to evaluate the contribution of the potential axes of rotation (minimum inertia axis, shoulder-centre of mass axis and the shoulder-elbow axis) during the four discrete tennis serve phases (loading, cocking, acceleration and follow through). Ten ranked athletes (International Tennis Number 1–3) repeatedly performed a flat service aiming at a target on the other side of the net. The four serve phases are distinct and thus, each movement phase seems to be organised around specific rotation axes. The results showed that the limbs’ rotational axis does not necessarily coincide with the minimum inertia axis across the cocking phase of the tennis serve. Even though individual serving strategies were exposed, all participants showed an effect due to the cocking phase and changed the rotation axis during the task. Taken together, the results showed that despite inter-individual differences, nine out of 10 participants changed the rotation axis towards the minimum inertia and/or the mass axis in an endeavour to maximise external rotation of the shoulder to optimally prepare for the acceleration phase. 相似文献
