Childhood sport participation is argued to be important to understand differences in self-regulation and performance level in adolescence. This study sought to investigate if football-specific activities in childhood (6–12 years of age) is related to self-regulatory skills and national under 14- and 15-team selection in Norwegian elite youth football. Data of practice histories and self-regulatory skills of 515 youth football players selected at Norwegian regional level were collected and further analysed using multilevel analyses. The results revealed that high self-regulated players were more likely to be selected for national initiatives, and increased their involvement in peer-led football practice and adult-led football practice during childhood, compared to players with lower levels of self-regulation. While national level players reported higher levels of peer-led football play in childhood, the interaction effect suggest that the regional level players increased their involvement in peer-led play during childhood compared to national level players. In conclusion, the findings indicate that childhood sport participation may contribute to later differences in self-regulation, and highlights the importance of childhood engagement in football-specific play and practice in the development of Norwegian youth football players. 相似文献

Drawing from Cervantes-Soon’s (2012) framework of testimonios as confessions, counter-narratives, and consejos, we explore how writing letters to our children serves as a process of historical documentation, healing, and a passing down of social justice principles and family history. Additionally, we expand on Cervantes-Soon’s framework by utilizing testimonios as a process by which to affirm intergenerational memory. Finally, connections are made to the potential role of letter writing as an important pedagogical tool. 相似文献

The purpose of the present study was to investigate how self-concept and attributional style are related to depression in a student group. On the basis of an inventory, 166 advanced teacher students were scored on general and academic self-esteem, attribution for positive and negative events, and depression. The two self-esteem variables were found to constitute important predictors of depression, while the contributions of the attributional variables were of minor importance. In addition, pessimistic attributions to both positive and negative events resulted in higher depression than pessimistic attributions to either kind of events, and to neither kind of events. Finally, factor analysis resulted in interpretable solutions. 相似文献

We argue in this paper that the systematic use of special software in instruction has a profound impact on the notion of function as an abstract entity to be constructed. We argue that through the medium of the computer, the objects in the graphical, tabular and algebraic settings can change their essence and thus become objects of a new kind we callrepresentatives. Actions on representatives which naturally arise in this framework induce an ontological shift. A taxonomy of the skills involved in the learning of the concept of function through these new ontological lenses is presented, as well as software, and problem solving tasks that embody the same ontological perspective. Within the framework of a teaching experiment, students' acquisition of many of the identified skills was investigated by means of a questionnaire and interviews during computer supported problem solving sessions. The most salient results of the study indicate that a majority of students were able (1) to cope with partial data about functions (e.g., problems of interpolation and arbitrariness), (2) to recognize invariants (i. e., properties of functions) while coordinating actions among representatives from different settings, and (3) to recognize invariants while creating and comparing different representatives from the same setting. 相似文献
