Para-adventure: a hyper-dynamic problem for the inclusive coach

Recent research has recognized sports coaching as complex, chaotic and cognitively taxing for coaches. Against this backdrop, the present paper explores challenges faced by high-level coaches working with disabled performers. Specifically, it seeks to understand how coaches create mental models of performance in adventure sports and para-canoe. Five coaches were purposively sampled and underwent a semi-structured interview. A thematic analysis revealed conceptualizing the mental model as being mechanically related for all and as including a social construction within the para-canoe coaches. Reflection on the coaching process and on personal characteristics were perceived as important to individualized inclusive coaching. Coach training should particularly emphasize the need for critical judgement and decision-making skills within a similarly oriented social structure of coaches and support staff where applicable.     

Youth leaders' perceptions of commitment to a responsibility-based physical activity program

This study extended Schilling's (2001) study by investigating program commitment among a larger (N = 12), older (M = 16.7 years), and more experienced (M = 5.96 years) sample of participants in the Project Effort Youth Leader Corps. Individual interviews elicited a greater number and specificity of themes. Program-related barriers included logistics, structure, and relationships, and personal-related barriers included perceived alternatives, personal characteristics, and "real-life" responsibilities. Similar to Schilling's (2001) earlier study, antecedents grouped under program environment, program structure, relationships, and personal characteristics. Participants also described outcomes in terms of behavior and emotional involvement but reported more themes related to leadership. Results are discussed in terms of consistencies and changes over time and implications for program development, expansion, and evaluation.     

Examining listening previewing as a classwide strategy to promote reading comprehension and vocabulary

Classwide instructional strategies to improve not only reading fluency but also comprehension and vocabulary knowledge are essential for student reading success. The current study examined the immediate effects of two classwide listening previewing strategies on reading comprehension and vocabulary knowledge. Twenty‐one, fourth‐grade general education students were exposed to three experimental conditions including a silent reading control condition, a listening previewing condition, and a listening previewing with vocabulary previewing condition. For all conditions, students read grade‐level passages, answered 10 comprehension questions, and completed a vocabulary‐matching task. Results showed that both listening previewing conditions led to improvements in comprehension as compared to silent reading. Adding a vocabulary previewing component to listening previewing procedures resulted in the highest levels of comprehension and vocabulary. Applied implications and directions for future research are discussed. © 2010 Wiley Periodicals, Inc.     

The Relationship between Children's Emotional and Behavioral Problems and the Social Responses of Elementary School Teachers

This study examined the relationship between children's emotional and behavioral problems and teachers' social responding. Elementary school students completed the Children's Depression Inventory and a parent completed the Child Behavior Checklist. Teachers rated children on measures of interpersonal attractiveness and personal rejection. Teachers' ratings of student interpersonal attractiveness were significantly correlated with the level of student depression, internalizing problems, externalizing problems, and overall psychopathology. However, teachers' ratings of personal rejection toward students only correlated with externalizing behavior problems. Family income was also related to child adjustment and teacher ratings. Externalizing behavior problems best predicted both lower interpersonal attractiveness and increased personal rejection, even after controlling for family income. Copyright 1999 Academic Press.     

MyTeachingPartner-Math/Science pre-kindergarten curricula and teacher supports: Associations with children's mathematics and science learning

MyTeachingPartner-Math/Science (MTP-MS) is a system of two curricula (math and science) plus teacher supports designed to improve the quality of instructional interactions in pre-kindergarten classrooms and to scaffold children's development in mathematics and science. The program includes year-long curricula in these domains, and a teacher support system (web-based supports and in-person workshops) designed to foster high-quality curricular implementation. This study examined the impacts of the intervention on the development of mathematics and science skills of 444 children during pre-kindergarten, via school-level random assignment to two intervention conditions (Basic: MTP-M/S mathematics and science curricula, and Plus: MTP-M/S mathematics and science curricula plus related teacher support system) and a Business-As-Usual control condition (BaU). There were intervention effects for children's knowledge and skills in geometry and measurement as well as number sense and place value: Children in Plus classrooms made greater gains in geometry and measurement, compared with those in BaU classrooms. Children in Plus classrooms also performed better on the number sense and place value assessment than did those in Basic or BaU classrooms. We describe the implications of these results for supporting the development of children's knowledge and skills in early childhood and for developing and providing teachers with professional development to support these outcomes.     

PERSONAL AND SCHOOL CULTURAL FACTORS ASSOCIATED WITH THE PERCEPTIONS OF TEACHERS’ EFFICACY IN HANDLING STUDENT MISBEHAVIOR

One approach for understanding teachers’ behavioral responses to classroom student misbehavior is through the perceptions of efficacy in handling this stressor. The present study investigated the relationship and predictive ability of personal and school cultural factors as they relate to perceptions of teachers’ efficacy in handling student misbehavior (TEHSM). Participants were 344 primary (n = 189) and secondary (n = 155), full‐time, public school teachers from a southeastern state in the USA. Teachers completed online self‐report measures of TEHSM and all personal and school cultural factors. Student socioeconomic status (SES) information was provided by the school districts. Structure equation modeling (SEM) results indicated the final empirical model to account for 66% of the variance in TESHM, with professional development and student SES having the strongest association with TEHSM. This study provides a vital step towards understanding factors that drive teachers’ perceptions of their efficacy in handling misbehaving students.
