In Cyprus, the pilot programme for the introduction of Information and Communication Technology (ICT) in elementary schools aimed at ICT as a cross-curricular tool and involved a combination of centralised initiative and largely decentralised implementation responsibility. Two independent studies on curricula integration indicated that parents' and teachers' preferred models as well as teachers' applied models vary widely. These models range from the technocentric (applying ICT as a discrete subject) to the humanistic curriculum (using ICT as a cross-curricular tool). The findings indicate that the challenge is on the policy makers to decide which model to adopt so as to specify the role of ICT in the National Curriculum and to create an appropriate infrastructure to support the model adopted. 相似文献

Whilst previous research has highlighted significant relationships between golfers’ clubhead velocity (CHV) and their vertical jump height and maximum strength, these field-based protocols were unable to measure the actual vertical ground reaction force (vGRF) variables that may correlate to performance. The aim of this study was to investigate relationships between isometric mid-thigh pull (IMTP), countermovement jump (CMJ), squat jump (SJ) and drop jump (DJ) vGRF variables and CHV in highly skilled golfers. Twenty-seven male category 1 golfers performed IMTP, CMJ, SJ and DJ on a dual force platform. The vertical jumps were used to measure positive impulse during different stretch-shortening cycle velocities, with the IMTP assessing peak force (PF) and rate of force development (RFD). Clubhead velocity was measured using a TrackMan launch monitor at a golf driving range. Pearsons correlation coefficient analyses revealed significant relationships between peak CHV and CMJ positive impulse (r = 0.788, p < 0.001), SJ positive impulse (r = 0.692; p < 0.001), DJ positive impulse (r = 0.561, p < 0.01), PF (r = 0.482, p < 0.01), RFD from 0–150 ms (r = 0.343, p < 0.05) and RFD from 0–200 ms (r = 0.398, p < 0.05). The findings from this investigation indicate strong relationships between vertical ground reaction force variables and clubhead velocity. 相似文献

New systems that seek to evaluate teachers with regard to their classroom quality often rely on observation instruments that capture general instructional pedagogies. However, decades of research suggest that content-specific dimensions of instruction also are important to differentiate teachers and improve student outcomes. We explore the degree of overlap between a general and a content-specific instrument when capturing upper elementary teachers’ mathematics instruction. To do so, we conducted exploratory and confirmatory factor analyses on data from more than 2,000 videotaped lessons scored using both the Classroom Assessment Scoring System, a general instrument, and the Mathematical Quality of Instruction, a content-specific instrument. Findings indicate that there is some overlap between instruments but that preferred factor structures include both general and content-specific practices. 相似文献

Sprint push-off technique is fundamental to sprint performance and joint stiffness has been identified as a performance-related variable during dynamic movements. However, joint stiffness for the push-off and its relationship with performance (times and velocities) has not been reported. The aim of this study was to quantify and explain lower limb net joint moments and mechanical powers, and ankle stiffness during the first stance phase of the push-off. One elite sprinter performed 10 maximal sprint starts. An automatic motion analysis system (CODA, 200 Hz) with synchronized force plates (Kistler, 1000 Hz) collected kinematic profiles at the hip, knee, and ankle and ground reaction forces, providing input for inverse dynamics analyses. The lower-limb joints predominately extended and revealed a proximal-to-distal sequential pattern of maximal extensor angular velocity and positive power production. Pearson correlations revealed relationships (P < 0.05) between ankle stiffness (5.93 ± 0.75 N x m x deg(-1)) and selected performance variables. Relationships between negative power phase ankle stiffness and horizontal (r = -0.79) and vertical (r = 0.74) centre of mass velocities were opposite in direction to the positive power phase ankle stiffness (horizontal: r = 0.85; vertical: r = -0.54). Thus ankle stiffness may affect the goals of the sprint push-off in different ways, depending on the phase of stance considered. 相似文献

Teachers’ concerns and efficacy beliefs about implementing a mathematics curriculum reform: integrating two lines of inquiry 总被引：1，自引：0，他引：1
This article discusses the possibility of using nonprofessional tutoring as means for advancing low achievers in secondary
school mathematics. In comparison with professional, paraprofessional, and peer tutoring, nonprofessional tutoring may seem
less beneficial and, at first glance, inadequate. The described case study shows that nonprofessional tutors may contribute
to students' understanding and achievements, and thus, they can serve as an important assisting resource for mathematics teachers,
especially in disadvantaged communities. In the study, young adults volunteered to tutor low-achieving students in an urban
secondary school. Results showed a considerable mean gain in students' grades. It is suggested that affective factors, as
well as the instruction given to tutors by a specialized counselor, have played a major role in maintaining successful tutoring. 相似文献

This study reports two different experiments, as a part of a longitudinal study, that evaluated a cognitive intervention (PREP:
PASS Reading Enhancement Program) to enhance early phonological processing skills, such as odd-word-out, segmenting, and blending,
to kindergarten children at-rish for reading difficulties, in order to support the development of subsequent word reading
skills. As part of the first experiment, thirty children aged 5.1, matched on the basis of age, gender, parental education
levels, Non-verbal and Verbal IQ, were assigned to an experimental and a control group (15 in each group) and compared before
and after the four-week intervention on a set of phonological and cognitive (successive and simultaneous processing) measures.
The two groups of participants were screened to be significantly different at pre-test on the outcome measures. The results
of the first experiment indicated that the experimental group performed equally well with the control group on all the measures
of phonological and cognitive processing skills. Subsequent analysis focusing on aptitude-treatment interaction indicated
that the PREP program appeared to be optimally successful in improving phonological skills in cases where the cognitive profile
of the 5-year-olds matched the emphasis on successive information integration. The follow-up experiment examined the long-term
effects of PREP remediation. Results showed that both the experimental and control groups performed equally well on word reading
tasks and, more importantly, on the bridging PREP tasks, requiring knowledge of the alphabet and of letter-sound correspondences,
despite that neither of the groups had been previously trained on the latter. Discussion concludes that intervention including
inductive training on the distal cognitive processes, namely successive and simultaneous processing, appears to be effective
for enhancing early word-reading skills to kindergarten children at-risk for reading difficulties, even in the absence of
direct training of these skills in kindergarten. 相似文献

This paper focuses on efficacy beliefs with respect to teaching mathematics; it aims at testing and validating an existing
scale for measuring efficacy beliefs in the domain of mathematics, examining the development of preservice teachers’ efficacy
beliefs in mathematics during fieldwork, and identifying factors that contribute to the development of these beliefs. Exploratory
factor analysis applied to longitudinal data collected through a questionnaire administered to almost 90 preservice teachers
elicited a two-factor model, reflecting efficacy beliefs in mathematics instruction and classroom management. Using cluster
analysis, we found four patterns in the development of preservice teachers’ efficacy beliefs regarding these two factors.
Our analysis of semi-structured interviews with eight participants representing these four patterns suggested that preservice
teachers’ efficacy beliefs were mainly informed by experimentation with teaching and interaction with mentors, tutors, peers,
and pupils. Based on our findings, we draw implications for mathematics preservice teacher education and provide suggestions
for future research.

This paper looks at teachers' interpretations of a recent and controversial Greek–Cypriot policy initiative, which aimed to promote ‘peaceful coexistence’ between the two rival communities in conflict‐ridden Cyprus. Specifically, it focuses on the ways in which Greek–Cypriot teachers constructed the relation between the new policy for peaceful coexistence between Greek‐Cypriots and Turkish‐Cypriots with the long established but rather conflicting policy of ‘I don't forget and I struggle’. The study analyses a set of 40 interviews conducted a few months after the first introduction of the new policy and maps teachers’ interpretations using the analytical concept of interpretative repertoires. Despite the poor implementation of the new initiative in practice, the study argues that the introduction of the new policy has brought about discernible discursive shifts in some teachers’ perceptions of the older policy of ‘I don't forget’. 相似文献

While research has focused on the role of racism in (re)producing ethnic/racial inequalities in education, there is very little research that investigates how variability in minority students’ responses to racism can be explained. By using an ecological approach to integrate existing research on actors’ responses to racism, this study finds that researchers have generally neglected factors and processes situated at the micro- and meso-levels of analysis. Qualitative interview data with Turkish–Cypriot children enrolled in schools in the predominantly Greek-speaking part of the Republic of Cyprus are used to investigate their strategies in response to racism and the factors that explain the observed variability in their responses. The findings suggest the importance of and interactions between factors situated at different levels of analysis, including the level of organizations and social groups and face-to-face interactions in explaining variability in young people’s responses to racism. 相似文献
