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   

In vitro evaluation of a program for machine-aided indexing     

Christian Jacquemin  Batrice Daille  Jean Royaut  Xavier Polanco 《Information processing & management》2002,38(6)

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

ABSTRACT

Mental 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 (M_age = 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   

Academic Learning Time in Elementary and Secondary Physical Education Classes     

Paul Godbout  Jean Brunelle  Marielle Tousignant 《Research quarterly for exercise and sport》2013,84(1):11-19

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   

Effects of Goal Setting on Achievement in Archery     

Mary L. Barnett  Jean A. Stanicek 《Research quarterly for exercise and sport》2013,84(3):328-332

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   

From Marin County's Seventies Clunker to the Durango World Championship 1990: A History of Mountain Biking in the USA     

Frédéric Savre  Jean Saint-Martin  Thierry Terret 《国际体育史杂志》2013,30(11):1942-1967

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

Learning movement culture: mapping the landscape between physical education and school sport     

Gavin Ward 《Sport, Education and Society》2013,18(5):569-604

This article examines Movement Culture as an approach to support teachers in exploring the integration of Sport as a medium for learning within Physical Education. By avoiding the need to draw clearly defined lines between Physical Education and Sport, Movement Culture embraces both. It acknowledges the need for subject matter in Physical Education to reflect societal shifts towards greater individualisation and means of seeking self-realisation, through individual and collective movement practices. Movement Culture maintains the educational purpose of Physical Education by developing meaningful subject matter and contextualised learning that reflect contemporary and evolving participation in Sport. Structural components for two frameworks are developed from an analysis of learning within Movement Culture. The frameworks are then employed to explore potential subject matter drawn from Sport. It is argued the structure of these frameworks retain sufficient portability to different Sports or groups of Sports and thus track developments in Movement Culture. Such structures also have the potential to support a more coherent rationale for pedagogical practice across Physical Education curricula.  相似文献   

A Comparison of Statistical Models for Calculating Reliability of the Hoffmann Reflex     

A. Christie  G. Kamen  Jean P. Boucher  J. Greig Inglis 《Measurement in physical education and exercise science》2013,17(3):164-175

The Hoffmann reflex is obtained through surface electromyographic recordings, and it is one of the most common neurophysiological techniques in exercise science. Measurement and evaluation of the peak-to-peak amplitude of the Hoffmann reflex has been guided by the observation that it is a variable response that requires multiple trials to obtain a stable mean. As a result, reliability assessment of the Hoffmann reflex has thus far been limited to trial-to-trial variability or the mean of multiple trials across test days to evaluate day-to-day variability, without considering how the two dimensions of measurement interact to affect test–retest reliability. This article compares two analysis of variance models for reliability assessment of the peak-to-peak amplitude of the Hoffmann reflex: one model incorporated both days and trials, and the other used the mean of multiple trials on each test day. The intraclass correlation coefficient calculated from an analysis of variance model that incorporated both trial-to-trial and day-to-day error variances was R = .93. Using the mean of the trials for each test day as a single score resulted in a decrease in the intraclass correlation coefficient (R _2,1 = .76). This study demonstrated that an analysis of variance model that accounts for both trial-to-trial and day-to-day error variances provided a higher estimate of reliability. Further, reliability estimation based on the interaction between both trials and days revealed that a schedule with additional test days had a disproportionate impact upon securing a reliable measure of Hoffmann reflex amplitude.  相似文献   

Changing Patterns of Residential Care: A Report on the 1988 CIRI Survey of Children in Resident Care     

Sandra Bocher  James Ward 《International Journal of Disability, Development & Education》1991,38(2):151-170

PLACEMENT IN residential care continues to be an option for children who need substitute care. However, the number of children involved at any time is often uncertain, as a result of the diversity of agencies, government and nongovernment, that provide these services. The Children in Residential Institutions Program (CIRI) within the Special Education Program of the Department of Education, Employment and Training provides a unique means for identifying the number of children in residential care in Australia at any time. A national census of children in residential care was conducted in association with the CIRI Program in 1983 and repeated and replicated in 1988 in New South Wales and Victoria. Results showed that there had been changes in the numbers and category of children requiring care over the study period. There were fewer large congregate‐style residences and more small units and family group homes. The study highlights the need for collection of accurate data about the number of children in residential care and the type of services that are provided.  相似文献
