Children's Activity Levels and Lesson Context during Third-Grade Physical Education

Abstract

Little is known about children's activity levels during physical education classes and how they relate to the national health objectives for the year 2000 (U.S. Public Health Service, 1991). We systematically observed students' physical activity and associated variables in 293 third-grade physical education lessons in 95 schools in 4 Child and Adolescent Trial for Cardio-vascular Health (CATCH) centers in California, Louisiana, Minnesota, and Texas. The influence of independent variables was assessed simultaneously by analysis of variance. Significant differences among study centers were evidenced for both physical activity and lesson context variables. Additionally, there were differences among variables for lesson location and teacher specialty, but not for teacher gender. Boys were more active than girls, but only during free play opportunities. The findings have widespread implications for educators responsible for developing and implementing health-related physical education programs, as well as for designing and conducting staff development.     

Providing Subscale Scores for Diagnostic Information: A Case Study When the Test is Essentially Unidimensional

Although reliability of subscale scores may be suspect, subscale scores are the most common type of diagnostic information included in student score reports. This research compared methods for augmenting the reliability of subscale scores for an 8th-grade mathematics assessment. Yen's Objective Performance Index, Wainer et al.'s augmented scores, and scores based on multidimensional item response theory (IRT) models were compared and found to improve the precision of the subscale scores. However, the augmented subscale scores were found to be more highly correlated and less variable than unaugmented scores. The meaningfulness of reporting such augmented scores as well as the implications for validity and test development are discussed.     

Friendship similarities in internalizing problems in early childhood

A key factor identified in friendship formation and stability is similarity. Homophily of externalizing problems has been reported frequently, but less attention has been directed at homophily of internalizing problems. Whether young children who are friends resemble each other in their internalizing problems is thus largely unknown. In order to increase understanding of the social risk factors implicated in the etiology of internalizing problems, it is important to establish whether internalizing problems cluster in friendships. The present study examines homophily of internalizing problems while controlling for externalizing problems in a sample of children aged 4–8.     

Transformations and self-discovery: mature-age women's reflections on returning to university study

Research has highlighted the challenges that women face as mature-age students in higher education. The challenges are particularly acute when a woman is the first in her family to go to university. Many women begin their journey as students with considerable self-doubt and lack of confidence. They may also face an ongoing struggle to find a way to combine their studies with other family responsibilities. This article presents the reflections of 18 women enrolled as mature-age students at an Australian university campus. Their triumphs, achievements and self-discoveries, as well as their struggles whilst undertaking their studies, are explored. In presenting the reflections of this group, the transformative nature of these experiences is highlighted, not only for the women themselves, but also potentially for their families, particularly their children. These narratives of achievement and transformation ultimately provide inspiration to other women contemplating such a step as well as insight for academic administrators and teaching staff regarding the significant personal change this decision can engender.

Decreasing inappropriate vocalizations using classwide group contingencies and color wheel procedures: A component analysis

Teacher referrals for consultation resulted in two independent teams collecting evidence that allowed for a treatment component evaluation of color wheel (CW) procedures and/or interdependent group‐oriented reward (IGOR) procedures on inappropriate vocalizations in one third‐ and one first‐grade classroom. Both studies involved the application of B‐C‐D‐C designs, with the initial B phase involving the application of independent group‐oriented punishment (IGOP) procedures that were applied in all classrooms at the respective schools and maintained across all phases of the studies. In Study I, the C phase involved that application of IGOP, IGOR, and CW; CW was withdrawn in the D phase and reinstated in the subsequent C phase. In Study II, IGOP procedures were supplemented with CW procedures (first C phase), then IGOR procedures were added (D phase) and withdrawn (second C phase). Results from the two studies converge and provide evidence that CW procedures are effective when applied with IGOP procedures and that supplementing them with IGOR procedures may have little classwide impact on inappropriate vocalizations. © 2010 Wiley Periodicals, Inc.
