Quantifying countermovement jump (CMJ) and landing knee flexion angle is important for performance and injury risk assessment. The purpose of the study was to compare electrogoniometer (El-Gon)- and video-derived CMJ and landing knee flexion angle. Twenty-two adults performed three CMJs while knee flexion angle was simultaneously assessed using an El-Gon and video. The average systematic offset (RMSE) of the El-Gon-derived knee flexion angle throughout the entire movement was 7.03°?±?2.69°. Excellent reliability was demonstrated by the El-Gon (ICCavg?=?0.92). Countermovement knee flexion angle, maximum landing knee flexion angle and flexion angle at maximum vertical ground reaction force were 12.0°, 10.9°, and 5.7° higher, respectively, when assessed using El-Gon (p?<?0.001), compared to video. Errors between instruments are likely due to El-Gon crosstalk, misalignment and/or axis determination. The El-Gon is a cost-effective and time-efficient alternative to video analysis for the assessment of knee flexion angle if the error is accounted for and the sensor is precisely attached. 相似文献

The purpose of the study was to examine the experiences of international graduates to find out how they perceived their new learning environment in Singapore, and to explore the strategies they employed to adjust to, manage and construct meaning out of their learning situation. A qualitative, critical incidents methodology was used in the research. It was found that adjustment for students was most difficult in the first 6 to 12 months from entry into the new cultural context, largely due to the influence of previous educational and cultural experiences on expectations. Four major themes were identified in the student experiences those of marginalisation: student/supervisory relationship, academic/organisational marginalisation, social marginalisation and advantaging. The coping strategies identified were those of self-determination, collegial support and examination strategies. The importance of collegial support as a key coping strategy for international student adjustment was confirmed in the study. Implications arising from the study may inform intervention programmes that are directed to the points of tension identified in students’ experiences. 相似文献

ABSTRACTFederal laws require schools to incorporate co-teaching environments, often comprised of an inclusion specialist and content specialist. Research shows individual teachers can make improvements to their practice by engaging in critical reflection through noticing. The authors present a research-based professional development model designed for teachers to improve and enhance their co-teaching practices. Findings included: teachers’ beliefs on teaching became more aligned; teachers’ beliefs on collaboration were inconsistent; teachers tended to focus on their teaching, not on student learning; and, teachers were non-cognizant of their beliefs toward teaching and co-teaching. We articulate ideas resulting from these findings for enhancing professional development experiences for co-teachers. 相似文献

This article reports on the third phase of a larger study that explored the perceptions of teachers about distributed leadership practices for inclusive education (IE) in primary schools involved in IE reform in Bangladesh. The Distributed Leadership Practice for Inclusive Education scale was developed specifically for this study to collect data. Participants for the present study were head teachers and teachers from 308 public primary schools. The results of this study indicate that teachers perceived that distributed leadership practices for IE were present in primary schools in Bangladesh. The findings indicate that teachers' perceptions about distributed leadership practices for IE have a significant positive correlation with their satisfaction about the implementation of IE policy. 相似文献

Abstract Understanding teachers' perceptions of a web-based, case-based learning environment provides insight into the effective development and deployment of such conditions for preparing educators. CaseNET–a web-based, case-method teaching environment for professional educators–serves as both a source of information as well as a space for inservice and preservice teachers to interact with one another and to contemplate current educational issues as they relate to real-world teaching. A qualitative analysis of over 400 participants was conducted and results provided. Participants perceived CaseNETas an opportunity to engage in professional development via exploration, reflection, collaboration, and hands-on interactions with authentic teaching tasks. Results suggest that the combination of cases and technology provides a valued opportunity to engage developing teachers in professional behaviors. 相似文献

With the introduction of Information and Communication Technologies (ICT) into schools came the expectation that teachers would adopt ICT and change their practices in particular ways. Research indicates that teachers have not changed in the ways expected. Suggested in this paper is that limitations in current research methodologies documenting change in teachers' practices are restricting thorough examination of change in teachers' practices mediated by ICT. This paper reports on the design of a study aimed at investigating teachers' practices from an alternative position from the current research. The research design is a grounded, longitudinal, qualitative study using assorted analysis for the collection and interpretation of the data. This involves a combination of secondary analysis of archive data and collection and analysis of primary data. Participants were able to retrospectively describe and understand their own archived and new data, in interviews and observations. This paper focuses on ways this research design supported examining teachers' practices as including a number of dimensions and the way these dimensions were influenced by the context in which they were situated. Also, the ways this research design provided a means for examining the changes that developed from the teachers' own narratives. This gave some insight into the ways the teachers' understood the changes in their own practices. Examining change from this perspective supports understanding of how and why changes in teaching practices mediated by ICT occur or don't occur. It also contributes to examining the bigger phenomenon of ICT and the long‐term impact it is having on teaching practices. 相似文献

Educators concerned about gifted learners are moving toward an evidence-based perspective focusing on children with exceptionally advanced learning needs who require flexibly responsive educational attention. This article describes two system-wide implementation experiences, one in a mixed urban/rural public school board and the other in an urban board of affiliated parochial schools, designed to meet the educational needs of diversely competent students. The authors discuss the intersecting roles of consultants, teachers, administrators, and parents, and some creative applications they have implemented that illustrate a respect for (a) teachers' professionalism, (b) individual developmental diversity, and (c) context-specific opportunities and constraints. The authors discuss ways that this flexible collaborative approach to integrating consultative processes into board-wide practices addresses the diverse educational needs of gifted learners, and also encourages high-level outcomes in learners not formally identified as gifted. 相似文献

ABSTRACTThis article suggests that situations in which multiple research teams are convened under similar conditions present an opportunity to discover factors that lead to productive collaboration. It argues that social network analysis of research team outputs becomes more valuable when paired with data about research participant perceptions; and that any variables used as indicators of collaboration need to be calibrated using datasets from multiple studies with cross-team comparisons. The article provides an example of the kind of methodology needed to achieve this, describing a study with data from four research teams based at an Australian university campus, reporting their research performance over four years under conditions in which many variables were controlled and with results augmented by a survey of participant perceptions. Findings from the study indicate that there were exceptions to hypothesized associations between participant perceptions of collaboration and specific social network analysis measures over co-authorship data. The article suggests that, given the methodological challenges of studying research teams in the field, multiple datasets combining findings such as those in the present study are a path towards the development of indicators of productive higher education research collaboration. 相似文献
