Purpose: A relationship exists between attitudes toward physical education and future physical activity. The purpose of this study was to examine changes in attitude toward physical education as students progressed from upper elementary school (Grade 4) through middle school (Grade 8). Method: Three cohorts of students (Cohort 1, Grades 4–6, = 96; Cohort 2, Grades 5–7, = 71; and Cohort 3, Grades 6–8, = 73) were each followed for 3 years to examine changes in attitudes toward physical education. Results: After an initial increase from Grade 4 to Grade 5, a significant decrease was observed from Grades 5 to 8 in students’ positive attitudes toward physical education, with a faster rate of change for girls than boys. Conclusion: This longitudinal study provides further insights regarding the attitudes of students as they progress from Grade 4 to Grade 8 and expands on previous findings identifying decreasing positive attitudes toward physical education as students age, particularly for girls. The results provide evidence to support targeted interventions.  相似文献

The procedures used to produce a research-based teaching evaluation system, containing low-inference indicators of effective and ineffective teacher behavior, included instrument development, content validation, and field testing. An extensive reliability study produced estimates for three types of consistency: intercoder agreement (r = 0.85), stability across teaching situations r = 0.86, and discriminant reliability among teachers (r = 0.79). The norming component of the study conducted in 45 schools, generated over 1200 observations of current teacher practice at all grade levels and in various subject areas. The results indicated the substantially generic nature of these behaviors; only grade level and instructional method (interactive, lecture, and independent seatwork) produced meaningful differences among groups of teachers. In addition, the average teacher used most of the effective behaviors (70%), and a few of the ineffective behaviors (8%) during observation. These results support the instrument's value in teacher training, remediation, and evaluation.  相似文献

Children’s book publishing has grown dramatically over the past ten years. John Donovan reviews trends in children's book publishing and bookselling, focussing on retail sales. Although he sees cause for satisfaction and optimism, he warns against complacency. He has written several books for young readers.  相似文献

As technology becomes more accessible and acceptable in the preschool setting, teachers need effective strategies of incorporating it to address challenging behaviors. A nonconcurrent delayed multiple baseline design in combination with an alternating treatment design was utilized to investigate the effects of using iPad tablets to display video self‐modeling and activity photos for three preschoolers during circle time. During baseline, all three children demonstrated low levels of engagement and high levels of off‐task behavior compared to peers. The intervention phase consisted of alternating between showing the child the self‐video and photos prior to circle time. A child preference phase was conducted whereby each child self‐selected the video or photo prior to circle time. For all three children both videos and photos led to increased engagement and decreased off‐task behaviors. During the child preference phase, all three children selected the video most frequently. Social validity data demonstrated teacher and child preference for the video self‐modeling condition.  相似文献
