Abstract

This study investigated the effects of instruction in environmental education on the attitudes of elementary school children toward the environment. One class of third graders was provided with two hours of environmental education instruction. A comparable class of third graders served as a control group. Both classes were pre- and posttested using an author-designed environmental attitude questionnaire. Analyses of these data showed that 1) the experimental group had significantly improved attitudes on a pre-post basis and 2) this same group had significantly more positive attitudes toward the environment when compared with the control group. When tested again as fifth graders, the experimental group remained significantly more positive toward the environment than the fifth grade control group.  相似文献

Race,Culture, and Intelligence: An Interview with Asa G. Hilliard III     

Grant E. Mabie 《The Educational forum》2013,77(3):243-251

Student achievement of the curriculum is the school's reason for being. This research, however, suggests that the behavior of school leaders is not effective in accomplishing four critical outcomes of curriculum development: (1) the creation of well-written documents that use a common framework; (2) curriculum that is aligned with state and national standards; (3) an understanding and teaching of the curriculum by teachers; and (4) all students successfully learning the curriculum. Leaders must orchestrate multiple changes that provide opportunities for teachers to work in teams, focus resources effectively on implementing the curriculum, and establish accountability for results.  相似文献   

Specific tackling situations affect the biomechanical demands experienced by rugby union players

Tackling in Rugby Union is an open skill which can involve high-speed collisions and is the match event associated with the greatest proportion of injuries. This study aimed to analyse the biomechanics of rugby tackling under three conditions: from a stationary position, with dominant and non-dominant shoulder, and moving forward, with dominant shoulder. A specially devised contact simulator, a 50-kg punch bag instrumented with pressure sensors, was translated towards the tackler (n = 15) to evaluate the effect of laterality and tackling approach on the external loads absorbed by the tackler, on head and trunk motion, and on trunk muscle activities. Peak impact force was substantially higher in the stationary dominant (2.84 ± 0.74 kN) than in the stationary non-dominant condition (2.44 ± 0.64 kN), but lower than in the moving condition (3.40 ± 0.86 kN). Muscle activation started on average 300 ms before impact, with higher activation for impact-side trapezius and non-impact-side erector spinae and gluteus maximus muscles. Players’ technique for non-dominant-side tackles was less compliant with current coaching recommendations in terms of cervical motion (more neck flexion and lateral bending in the stationary non-dominant condition) and players could benefit from specific coaching focus on non-dominant-side tackles.  相似文献   

Together for a Better Multicultural Society     

Carl A. Grant 《Multicultural Perspectives》2013,15(4):200-201

I propose that educators construct pedagogical responses to youth in schools in ways that consider classrooms to be the result of and the boardroom for complex global flows. Youth's production of individual and collective identities wherein flows are apprehended, discarded, combined, and recombined, rages against purifying processes of neocolonial classrooms.  相似文献

Temporal trends in 6-minute walking distance for older Japanese adults between 1998 and 2017     

Grant R. Tomkinson  Tetsuhiro Kidokoro  Trevor J. Dufner  Shingo Noi  John S. Fitzgerald  Holly M. Brown-Borg 《运动与健康科学(英文)》2021,10(4):462-469

BackgroundThe 6-minute walking distance (6MWD) is an excellent measure of both functional endurance and health. The primary aim of this study was to estimate temporal trends in 6MWD for older Japanese adults between 1998 and 2017; the secondary aim was to estimate concurrent trends in body size (i.e., height and mass) and self-reported participation in exercise/sport.MethodsAdults aged 65–79 years were included. Annual nationally representative 6MWD data (n = 103,505) for the entire period were obtained from the Japanese Ministry of Education, Culture, Sports, Science and Technology. Temporal trends in means (and relative frequencies) were estimated at the gender–age level by best-fitting sample-weighted linear/polynomial regression models, with national trends estimated by a post-stratified population-weighting procedure. Temporal trends in distributional variability were estimated as the ratio of coefficients of variation.ResultsBetween 1998 and 2017 there was a steady, moderate improvement in mean 6MWD (absolute = 45 m (95% confidence interval (95%CI): 43–47); percent = 8.0% (95%CI: 7.6%–8.4%); effect size = 0.51 (95%CI: 0.48–0.54)). Gender- and age-related temporal differences in means were negligible. Variability in 6MWD declined substantially (ratio of coefficients of variation = 0.89, 95%CI: 0.87–0.92), with declines larger for women compared to men, and for 75–79-year-olds compared to 65–74-year-olds. Correspondingly, there were moderate and negligible increases in mean height and mass, respectively, and negligible increases in the percentage who participated in exercise/sport at least 3 days per week and at least 30 min per session.ConclusionThere has been a steady, moderate improvement in mean 6MWD for older Japanese adults since 1998, which is suggestive of corresponding improvements in both functional endurance and health. The substantial decline in variability indicates that the temporal improvement in mean 6MWD was not uniform across the distribution. Trends in 6MWD are probably influenced by corresponding trends in body size and/or participation in exercise/sport.  相似文献   

The relationship between the Luria-Nebraska neuropsychological battery-children's revision and the Minnesota Percepto-Diagnostic Test with learning disabled students     

Jeffrey H. Snow  Lawrence C. Hartlage  George W. Hynd  Daniel H. Grant 《Psychology in the schools》1983,20(4):415-419

The Luria-Nebraska Neuropsychological Battery-Children's Revision (LNNB-Children's Revision) and The Minnesota Percepto-Diagnostic Test (MPD) were administered to 40 learning disabled (LD) students. Correlations were run between the scales of the LNNB-Children's Revision and MPD scores across the sample. Coefficients ranged from .07 to .71 for the intercorrelations of the scales of the LNNB-Children's Revision. Low correlations (−.10 to −.27) were found between MPD T scores and the LNNB-Children's Revision Scales, but raw scores from the MPD had somewhat higher correlations with the LNNB (.18 to .65).  相似文献   

Validation of self-report measures of physical activity: a case study using the New Zealand Physical Activity Questionnaire     

Mackay LM  Schofield GM  Schluter PJ 《Research quarterly for exercise and sport》2007,78(3):189-196

Accurate measurement of physical activity is fundamentally important in epidemiological research of physical activity behavior A widely used telephone-based physical activity questionnaire was compared with other methods of administration and objective measures (pedometers and accelerometers) among 80 adults (43 women). The telephone questionnaire was comparable to both the self-administered form and international telephone-administered equivalent. Although moderate correlation coefficients with objective measures supported the use of the questionnaire, wide prediction intervals generated using Bland Altman methods highlighted large discrepancies between the measures, particularly in the moderate intensity category. These findings illustrate the limitations of correlation coefficients in validation studies and the inaccuracy of self-report questionnaires in measuring physical activity.  相似文献
