Literacy instruction in first-grade classrooms in five U.S. locales was observed. Based on academic engagement and classroom literacy performances, the most-effective-for-locale and least-effective-for-locale teachers were selected. The teaching of the most-effective-for-locale teachers was then analyzed, including in relation to the teaching of the least-effective-for-locale teachers. The classrooms headed by most-effective-for-locale teachers were characterized by excellent classroom management based on positive reinforcement and cooperation; balanced teaching of skills, literature, and writing; scaffolding and matching of task demands to student competence; encouragement of student self-regulation; and strong cross-curricular connections. In general, these outcomes did not support any theory that emphasizes just one particular component (e.g., skills instruction, whole language emphasis) as the key to effective Grade 1 literacy; rather, excellent Grade 1 instruction involves multiple instructional components articulated with one another. 相似文献

Abstract The purpose of this research was to examine the beliefs, attitudes, and knowledge of early childhood teacher candidates within the state of Texas about the inclusion of students with disabilities in the general education classroom. The “Inventory of Opinions About Persons with Disabilities” (IOPD) was utilized to collect self‐report data from preservice educators in their last semester of practical experience (i.e., student teaching or final intern semester) in 10 Texas universities. The return rate of the inventories was 70.85%, with data from 172 useable inventories reported in this study. The research questions indicated early childhood teacher candidates held positive self‐perceptions (mean = 2.0388) about their beliefs, attitudes, and knowledge related to inclusion and students with disabilities. However, the participants reported less positive attitudes about training (mean = .09884). 相似文献

Leveraging the power of music to improve science education 总被引:1,自引:0,他引:1

We assessed the impact of music videos with science-based lyrics on content knowledge and attitudes in a three-part experimental research study of over 1000 participants (mostly K-12 students). In Study A, 13 of 15 music videos were followed by statistically significant improvements on questions about material covered in the videos, while performance on ‘bonus questions’ not covered by the videos did not improve. Video-specific improvement was observed in both basic knowledge and genuine comprehension (levels 1 and 2 of Bloom’s taxonomy, respectively) and after both lyrics-only and visually rich versions of some videos. In Study B, musical versions of additional science videos were not superior to non-musical ones in their immediate impact on content knowledge, though musical versions were significantly more enjoyable. In Study C, a non-musical video on fossils elicited greater immediate test improvement than the musical version (‘Fossil Rock Anthem’); however, viewers of the music video enjoyed a modest advantage on a delayed post-test administered 28 days later. Music video viewers more frequently rated their video as ‘fun’, and seemed more likely to revisit and/or share the video. Our findings contribute to a broader dialogue on promising new pedagogical strategies in science education. 相似文献

This article presents the human evaluation of ILIAD, a program for machine-aided indexing (MAI). It consists of two language engineering modules and is designed to assist expert librarians in computer-aided indexing and document analysis. Our aim is the expert evaluation of automatic multi-word term indexing. Evaluation is performed by documentary engineers. Cataloging and indexing are their principal tasks. They also have a good scientific knowledge of the domain to which the indexed documents belong.We first present the ILIAD program and the two systems submitted to this evaluation, the methodology (protocol) adopted, the differences between the protocol and the implementation, and the results of these evaluations. Human evaluation is divided into three parts: firstly the evaluation of controlled indexing, then free indexing and finally term variant extraction performed during controlled indexing. Finally, we analyze the relevance of this evaluation by calculating the agreement frequency and the Kappa coefficient and propose some future developments. 相似文献

ABSTRACTMental health is an important public health issue and up to one in five youth experience mental health problems. The primary purpose of this study was to examine the relationship among motor competence, health-related physical fitness and mental health outcomes in adolescents. A secondary goal was to test the direct and indirect effects of motor competence on adolescents’ mental health through health-related physical fitness. Participants were 279 adolescents (Mage = 12.49, SD = 0.89) recruited in the south-west region of the US Motor competence including volleyball, soccer, and ultimate Frisbee, were assessed using PE Metrics?. FITNESSGRAM® test battery was used to assess health-related physical fitness components. Students completed a survey measuring their depressive symptoms and health-related quality of life. Motor competence was significantly associated with components of health-related physical fitness (r ranged from ?0.15 to 0.38). The robust fit of the model supports the significant indirect effect of motor competence on mental health outcomes through health-related physical fitness (χ2/df = 39.92/25; CFI = 0.97; RMSEA = 0.046; 90% CI [0.02, 0.07]). The hypothesized conceptual model tested in this study provides insights into the potential interaction of motor competence and health-related physical fitness with adolescents’ mental health. 相似文献

AbstractStrenuous physical activity has been linked to pelvic floor disorders in women. Using a novel wireless intra-vaginal pressure transducer, intra-abdominal pressure was measured during diverse activities in a laboratory. Fifty-seven women performed a prescribed protocol using the intra-vaginal pressure transducer. We calculated maximal, area under the curve and first moment of the area intra-abdominal pressure for each activity. Planned comparisons of pressure were made between levels of walking and cycling and between activities with reported high pressure in the literature. Findings indicate variability in intra-abdominal pressure amongst individuals doing the same activity, especially in activities that required regulation of effort. There were statistically significant differences in maximal pressure between levels of walking, cycling and high pressure activities. Results for area under the curve and first moment of the area were not always consistent with maximal pressure. Coughing had the highest maximal pressure, but had lower area under the curve and first moment of the area compared to most activities. Our data reflect novel findings of maximal, area under the curve and first moment of the area measures of intra-abdominal pressure, which may have clinical relevance for how physical activity relates to pelvic floor dysfunction. 相似文献

Abstract The purpose of this study was to determine how much academic learning time is experienced by elementary and secondary school students during regular physical education classes (ALT-PE) and to investigate three major ALT variables, that is, time devoted to specific content areas, learner engaged time with relevant material, and student's success rate. Subjects were 30 elementary and 31 secondary school physical education teachers; all had two of their regular classes observed according to the ALT-PE observational procedure developed by Siedentop and his colleagues. Group average results were found to be consistent over time, but individual data showed very little stability. The ALT-PE mean results were 31.3% and 36.5% respectively for the elementary and secondary school level and were significantly different. From 19% to 34% of the class period was spent, on the average, in other than P.E. content activities. When class groups, as a whole, were involved in P.E. content activities, students, considered individually, were effectively engaged in those activities 50% of the time. The non-success rate of the students was found to be quite low (10% approximately) and, therefore, did not contribute greatly to decreasing the ALT-PE figures. It was felt that a better management of the student's involvement during P.E. content activities might contribute to increasing significantly the percentage of student academic learning time in a given class period. 相似文献

This study investigated the effects of goal setting in teacher-led group conferences on achievement in archery. University undergraduates enrolled in three beginning archery classes (N = 30) were randomly assigned to two treatment groups—group conference with goal setting and group conferences only. For 10 weeks, subjects met twice a week for archery instruction and once a week with the instructor for a 10-minute conference. Subjects in the goal-setting conference group were directed to set numerical and verbal goals using a printed goal-setting form. Three achievement tests were administered while subjects were shooting from a distance of 20 yards: an initial test during week 1, a progress test during week 6, and a final test during week 10. Analysis of the data indicated that when groups were adjusted for initial differences, the goal-setting group achieved significantly higher scores in archery than the non-goal-setting group (F = 5.31, p < .05). Motivational implications of goal setting procedures are discussed. 相似文献

Between the 1970s, during which several enthusiastic cyclists rode off-road, and the 1990s, during which the first Union Cycliste Internationale World Championship took place in Durango (Colorado), different steps contributed to the success of mountain bike in the US. Inventions took place throughout the period from Gary Fisher's mechanical improvements in 1975 to Joe Breeze's first specialized frames made in 1977. In the same fashion, the ‘Stumpjumper’ was sold on a large scale in 1982, making it the first industrially-produced mountain bike, which led to a new stage in terms of commercialization. The mountain bike opened a new market in the cycling industry and certainly became more financially accessible to a large number of people. This sport, which began in the US, became a worldwide outdoor sport in the last decade of the twentieth century when the Olympics welcomed it with open arms at the Atlanta Olympic Games. 相似文献
