Web-Based Student Assessment for Program Evaluation     

Coleman  Elaine B.  Penuel  William R. 《Journal of Science Education and Technology》2000,9(4):327-342

As part of an overall evaluation of the Global Learning and Observations to Benefit the Environment, (GLOBE) program, we designed a Web-based assessment environment to measure students' environmental awareness and data analysis skill. It was expected that students who were identified as high implementers in the GLOBE program would outperform low implementers in their ability to construct environmental inferences and the degree to which they could analyze environmental data. Seven high and middle school classrooms were identified as either high or low GLOBE implementers depending on the amount of atmospheric data they had collected during the year. Within each classroom students were assigned into smaller learning groups of three students per group. A total of 32 groups participated in this study. Analysis of students' responses to the tasks revealed that the students differed in their performance. Overall, the results showed that students in the high implementing classrooms were more likely to construct higher-level environmental inferences than students in the low implementing classes. Contrary to expectations, middle school students were more likely than high school students to solve the data analysis problem correctly. However, upon further analyses, high school students constructed more data graphs and were more skilled in providing correct evidence to support their decision making than were middle school students in GLOBE. This study confirms the viability of using technology-based assessments for measuring students' environmental awareness and data analysis.  相似文献

Match or Mismatch: The perceptions of parents of nursery age children related to those of the children's main nursery workers     

Barbara Riddick  Elaine Hall 《International Journal of Early Years Education》2000,8(2):113-128

The purpose of this study was to explore the extent to which shared aims, values and understanding exist both between parents and professionals and among professionals. Of particular concern was the impact that any differences in perspective might have on a given child. For each of seven case study children, one parent and two key nursery workers were interviewed and asked to complete rating scales. Thus, there were seven parent and 14 nursery practitioner interviews carried out. Interviews were analysed on a thematic basis with a particular focus on attributional analysis. It was found that, where there were differences between parents and practitioners in the attributions that they made for children's behaviour and learning that these had a significant influence on how children were understood and, in some cases, could lead to nursery practitioners underestimating or 'blaming' children and their families for perceived deficiencies. Cette étude avait pour objectif d'explorer s'iI existe des objectifs, des valeurs et des visions communes entre les parents et les professionnels et parmi les professionnels. On a examiné tout particulièrement l'impact potentiel de toute différence de perspective sur un enfant donné Pour chacun des 7 enfants ayant fait l'objet d'études de cas, un parent et deux enseignants-clés ont été interrogés et ont eu à remplir des questionnaires avec échelle d'évaluation. Il y a donc eu 7 entretiens avec des parents et 14 avec des enseignants de maternelle. Les entretiens ont été analysés sur une base thématique, en mettant un accent particulier sur 1'analyse des attributions. Il en est ressorti que lorsqu'il existait des différences entre les parents et les professionnels dans leurs attributions du comportement et 1'apprentissage des enfants, ces différences avaient une influence considérable sur la manière dont les enfants étaient compris et que, dans certains cas, elles pouvaient entraîner les professionnels à sous-estimer ou e blâmer f les enfants et leur famille pour des lacunes perçues.  相似文献

Effect of the look-up line on the gaze and head orientation of elite ice hockey players

Abstract

A “look-up line” (LUL) has been proposed for ice hockey, which is an orange 1?m (40′) warning line (WL) painted on the ice at the base of the boards. The LUL purports to provide an early warning to players to keep their head up prior to and as they are being checked. We determined if players looked up more on a rink with the LUL compared to a traditional Control rink. Elite offensive (O) and defensive (D) players competed 1 vs. 1, while wearing an eye tracker that recorded their quiet eye (QE) and fixation and tracking (F-T) and an electrogoniometer that measured head angle. External cameras recorded skate duration during four skate phases: P1 preparation, P2 decision-making, P3 cut to boards, P4 contact. The QE was the final fixation prior to contact between O and D as they skated towards and across the WL during P3 and P4. Skate phase durations (%) did not differ by rink or rink by position. More QE and F-T occurred on the WL on the LUL rink than on the Control. The expected increase in head angle on the LUL rink did not occur during P3 or P4. Post-hoc results also showed O and D skated further from the boards on the LUL rink, suggesting the players preferred to control the puck on white ice, rather than the orange colour of the LUL rink. More research is needed to determine if these results apply to the competitive setting.  相似文献   

Increasing hip and knee flexion during a drop-jump task reduces tibiofemoral shear and compressive forces: implications for ACL injury prevention training     

Liang-Ching Tsai  Yi-An Ko  Kyle E. Hammond  John W. Xerogeanes  Gordon L. Warren  Christopher M. Powers 《Journal of sports sciences》2017,35(24):2405-2411

Although most ACL injury prevention programmes encourage greater hip and knee flexion during landing, it remains unknown how this technique influences tibiofemoral joint forces. We examined whether a landing strategy utilising greater hip and knee flexion decreases tibiofemoral anterior shear and compression. Twelve healthy women (25.9 ± 3.5 years) performed a drop-jump task before and after a training session (10–15 min) that emphasised greater hip and knee flexion. Peak tibiofemoral anterior shear and compressive forces were calculated using an electromyography (EMG)-driven knee model that incorporated joint kinematics, EMG and participant-specific muscle volumes and patella tendon orientation measured using magnetic resonance imaging (MRI). Participants demonstrated a decrease in peak anterior tibial shear forces (11.1 ± 3.3 vs. 9.6 ± 2.7 N · kg^?1; P = 0.008) and peak tibiofemoral compressive forces (68.4 ± 7.6 vs. 62.0 ± 5.5 N · kg^?1; P = 0.015) post-training. The decreased peak anterior tibial shear was accompanied by a decrease in the quadriceps anterior shear force, while the decreased peak compressive force was accompanied by decreased ground reaction force and hamstring forces. Our data provide justification for injury prevention programmes that encourage greater hip and knee flexion during landing to reduce tibiofemoral joint loading.  相似文献   

Effect of Active Lessons on Physical Activity,Academic, and Health Outcomes: A Systematic Review     

Rosemarie Martin  Elaine M. Murtagh 《Research quarterly for exercise and sport》2017,88(2):149-168

Purpose: The purpose of this study was to conduct a systematic review of classroom-based physical activity interventions that integrate academic content and assess the effectiveness of the interventions on physical activity, learning, facilitators of learning, and health outcomes. Method: Six electronic databases (ERIC, PubMed, Google Scholar, Science Direct, Cochrane Library, and EMBASE) and reference lists were searched for English-language articles, published January 1990 through March 2015, reporting classroom-based interventions that deliberately taught academic content using physically active teaching methods for at least 1 week duration, with physical activity, health, learning, or facilitators-of-learning outcomes. Two authors reviewed full-text articles. Data were extracted onto an Excel spreadsheet, and authors were contacted to confirm accuracy of the information presented. Results: Fifteen studies met the inclusion criteria. Six studies reporting on physical activity levels were found to have medium-to-large effect sizes. All 4 studies reporting learning outcomes showed positive effects of intervention lessons. Teachers and students were pleased with the programs, and enhanced on-task behavior was identified (n = 3). Positive effects were also reported on students’ body mass index levels (n = 3). Conclusions: Physically active academic lessons increase physical activity levels and may benefit learning and health outcomes. Both students and teachers positively received and enjoyed these teaching methods. These findings emphasize the need for such interventions to contribute toward public health policy.  相似文献
