Extending the theory of planned behavior: the role of self and social influences in predicting adolescent regular moderate-to-vigorous physical activity

The current study aimed to test the validity of an extended theory of planned behavior model (TPB; Ajzen, 1991), incorporating additional self and social influences, for predicting adolescent moderate-to-vigorous physical activity. Participants (N = 423) completed an initial questionnaire that assessed the standard TPB constructs of attitude, subjective norm, and perceived behavioral control, as well as past behavior, self-identity, and the additional social influence variables of group norms, family social support, friends' social support, and social provisions. One week after completion of the main questionnaire, participants completed a follow-up questionnaire that assessed self-reported physical activity during the previous week. The standard TPB variable--past behavior, self-identity, and group norms, but not social support influences--predicted intentions, with intention, past behavior, and self-identity predicting behavior. Overall, the results provide support for an extended version of the TPB incorporating self-identity and those social influences linked explicitly to membership of a behaviorally relevant reference group.     

Teachers’ Conceptions of Gifted and Talented Young Children

Efforts by schools to cater more adequately for highly able students necessitate a shared understanding regarding the gifted and talented. This research aims to ascertain the qualitatively different ways in which teachers identify and describe gifted and talented children. It examines the variety of conceptions of giftedness held by teachers and analyses the patterns and inconsistencies among them. Initial findings of the study, conducted with 16 early childhood teachers (two male and 14 female), are reported. A qualitative phenomenographic research design was adopted because of its focus on revealing individual understandings (conceptions). These results show that teachers understand giftedness as a series of conceptions, namely excellence, potential, rarity, behaviour, innate ability, motivation and asynchrony. These are discussed with reference to existing theories and pertinent research. Results represent the initial findings of an ongoing major research project.
