The study investigated differences in the one‐ (SH) and two‐handed (DH) backhands when hit flat, across‐court (AC) and down‐the‐line (DL), and with heavy topspin DL (TDL). The ability to disguise each of these backhands when hitting the above strokes was also assessed. Eighteen college‐level male tennis players, identified as having a high performance topspin SH (n = 6) or DH (n = 12) backhand drive, participated in the study. Players were required to hit three AC, DL and TDL backhands from the baseline with their preferred technique, while being filmed with two high‐speed video cameras operating at 200 Hz. The highest horizontal velocity backhand for each stroke was analysed. Results indicated that the sequential coordination of five body segments (hips, shoulder, upper arm, forearm, and hand/racquet rotations) was required for the execution of the SH stroke. The same number of segments were generally coordinated in the DH stroke (hips, shoulders, and varying degrees of upper arm and forearm rotations followed by hand/racquet movement). Mature players produced comparable racquet horizontal velocities 0.005 s prior to impact using either the SH or DH backhand technique. The SH backhand was characterised by a more rotated shoulder alignment than the DH stroke (SH: 119.1°; DH: 83.4°) at the completion of the backswing. At impact the ball was impacted further in front (SH: 0.59 m; DH: 0.40 m) and a similar distance to the side of the body (SH: 0.75 m; DH: 0.70 m). Players using the DH backhand technique delayed the horizontal acceleration of the racquet towards the ball (SH: 0.13 s; DH: 0.08 s prior to impact) and thus were capable of displaying a similar hitting motion closer to impact than players with a SH technique.  相似文献

We investigated the contributions of stressful life events and resources (social support and social problem-solving skills) to predicting changes in children's adjustment. At Time 1, 361 third through fifth graders completed measures of social support and social problem-solving skills. Their parents completed a stressful life events scale and a child behavior rating measure. The children's teachers provided ratings of behavioral and academic adjustment. 2-year follow-up data (Time 2) were obtained for approximately half of the sample on the same measures. Time 1 stressful life events and resources showed some significant but modest zero-order correlations with the Time 2 adjustment indices. Hierarchical multiple regressions revealed prospective effects for Time 1 social support on later teacher-rated competencies and grade-point average. In addition, increases over time in social support and social problem-solving skills (a composite score) were significantly related to improvement in behavioral and academic adjustment, whereas stressful life events were not predictive of adjustment.  相似文献

Because several studies have investigated student outcomes in schools implementing Response to Intervention (RtI), relatively little research has investigated the impact of implementation on students’ long‐term achievement outcomes (i.e., several years after exposure). The purpose of this study was to describe one elementary school's RtI implementation process and to examine students’ long‐term reading comprehension outcomes following their exposure to various phases of implementation. Four cohorts of students who experienced different implementation phases (i.e., a baseline condition or Phases I, II, or III of implementation) during Grade 2 were subsequently followed across Grades 3, 4, and 5 to examine their outcomes on two reading comprehension measures. Results indicated that students who experienced the early phases of RtI implementation (i.e., Phases I and II) during Grade 2 generally had higher mean comprehension scores in Grades 4 and 5 than students in the baseline condition. Implications for practice and future research are discussed.  相似文献

This paper traces the dramatic proliferation of leadership roles in English primary and secondar schools, due mainly to central government education policy of the past two decades. This has transformed schools from relatively simple to highly complex organizations and has impacted on the working conditions of, and demands on, teachers, together with many aspects of schooling. These changes are illustrated with typical examples of schools' leadership structures and their functioning. Interview data provide teachers' views on, and reactions to, the changes in school leadership. The paper also reviews the ways in which teacher education institutions have responded in terms of providing initial and in‐service education and training to equip the profession for this new and developing challenge. It examines the reception of such programmes by teachers and the reported impact on schools' management and the role of leadership within it.  相似文献

This paper presents results from an experimental study that examined embedded strategy prompts in digital text and their effects on calibration and metacomprehension accuracies. A sample population of 80 college undergraduates read a digital expository text on the basics of photography. The most robust treatment (mixed) read the text, generated a summary for each page of text, and then was prompted with a metacognitive strategy. The metacognitive treatment received metacognitive strategy prompts only, and the cognitive group implemented the cognitive strategy (summarization) only. A control group read the text with no embedded support. Groups were compared on measures of achievement, attitudes, cognitive load, and metacomprehension and calibration accuracy. Results indicated that a combination of embedded cognitive and metacognitive strategies in digital text improved learner achievement on application-level questions, yielded more accurate predictive calibration, and strengthened the relationship between metacomprehension and performance, all of which are common attributes of an academically successful learner.  相似文献

The review acknowledges that research on the family and its contribution to achievement in ethnic minority children is important. Past research and theorizing suggest the need for new directions, however. For example, research in educational achievement predicts educational failure for African-American students and educational success for Asian-American students. Little differentiation is made either among African-Americans or among Asian-Americans of different cultural, language, immigration, and economic backgrounds. The theory and design of research on family and educational achievement have been influenced by prevailing societal stereotypes. Research and policy implications of this review include the need to move toward cultural/ecological theories of achievement socialization and development.  相似文献

Creativity is viewed in different ways in different disciplines: in education it is called ‘innovation’, in business it is ‘entrepreneurship’, in mathematics it is often equated with ‘problem solving’, and in music it is ‘performance’ or ‘composition’. A creative product in different domains is measured against the norms of that domain, with its own rules, approaches and conceptions of creativity.  相似文献

This is the first article to compare and contrast the outcomes of Office for Standards in Education (Ofsted) reports on the management of school attendance issues in primary and secondary schools, out-of-school and local education authorities (LEA) provision. The findings indicate that schools and LEAs are judged using very strict criteria based on a school's or LEA's authorized or unauthorized rates of attendance, which are then compared with national norms, targets and Ofsted criteria. By contrast, out-of-school providers, often pupil referral units (PRUs), are given much more latitude despite their more obvious and serious attendance difficulties. This paper presents an insight into the reasons given by Ofsted inspectors for making either their positive or negative judgements on schools', PRUs' or LEAs' performances on the management of their attendance agenda. The implications of these findings are considered and conclusions drawn based on the evidence. Further research will be necessary to compare the findings in this paper with subsequent outcomes given the proposed changes with Ofsted's methodology and criteria for conducting its future inspections.  相似文献

Effective teaching and learning in higher education is an important focal point of literature around the globe. Various models are presented as desirable and fostering optimal conditions for teaching and learning. However, each model must be examined within the context of its institutional culture, mission and strategic plan to ascertain if it meets the envisaged goals. The Reinventing Teaching Project survey conducted at Flinders University in 2009 provided a unique opportunity for academic staff and students across all faculties to respond to a survey that explored their perceptions of optimal learning conditions and assessed if the campus environment was conducive to effective teaching and learning practices. The exploratory study was designed to gather qualitative and quantitative data on the motivation of teachers and learners to engage with learning and learners (or not). The results of the survey present valuable insights into what teachers and learners consider to be important attributes of optimal teaching and learning and indicate a number of similarities and differences among teacher-student perceptions. This paper identifies and discusses some of the pertinent outcomes of the study to provide a framework for other similar studies.  相似文献
