Ecological dynamics of continuous and categorical decision-making: The regatta start in sailing

Abstract

Ecological dynamics of decision-making in the sport of sailing exemplifies emergent, conditionally coupled, co-adaptive behaviours. In this study, observation of the coupling dynamics of paired boats during competitive sailing showed that decision-making can be modelled as a self-sustained, co-adapting system of informationally coupled oscillators (boats). Bytracing the spatial–temporal displacements of the boats, time series analyses (autocorrelations, periodograms and running correlations) revealed that trajectories of match racing boats are coupled more than 88% of the time during a pre-start race, via continuous, competing co-adaptions between boats. Results showed that both the continuously selected trajectories of the sailors (12 years of age) and their categorical starting point locations were examples of emergent decisions. In this dynamical conception of decision-making behaviours, strategic positioning (categorical) and continuous displacement of a boat over the course in match-race sailing emerged as a function of interacting task, personal and environmental constraints. Results suggest how key interacting constraints could be manipulated in practice to enhance sailors' perceptual attunement to them in competition.     

Creation of reusable open textbooks: Insights from the Connexions repository

Open textbook initiatives have appeared as an alternative to traditional publishing. These initiatives for the production of alternatively copyrighted educational resources provide a way of sharing materials through the Web. While the open model of peer‐produced materials enables the global reuse of textbooks, the combination of fragments to produce new textbooks tailored to particular needs is not easy. The heterogeneity of topics and target audiences, as well as the cultural and institutional differences of educational systems across the globe, raises the need for new compositional features, fostering—at the same time—the reuse of the newly produced combinations. This paper reviews the current models of reuse and sharing, and presents a quantitative analysis of the Connexions repository which provides evidence about the culture of reuse in open textbook initiatives.     

The mediating role of social relationships in the association of adolescents’ individual school self-concept and their school engagement,belonging and helplessness in school

It is well known that teachers frequently observe a decline in the scholastic motivation of many adolescent students, which in turn is often associated with a decline in students’ individual school self-concept. In contrast, less is known about the association between students’ individual school self-concept and school engagement, or the related concepts of school belonging and helplessness in school. The current study explored social relationships as mediators in the association between individual school self-concept and adolescents’ school engagement, belonging to school and helplessness in school in a large sample of 7th and 8th grade students (N?=?1088; M_Age?=?13.7) in secondary schools in Brandenburg, Germany. The results of two structural equation models showed that the teacher–student relationship mediated the association between individual school self-concept and school engagement, belonging to school and helplessness in school, respectively. In contrast, the student–student relationship did not mediate any of these associations.     

International Approaches to Whole-of-School Physical Activity Promotion

Increasing physical activity opportunities in schools has emerged as a global priority among school-aged youth. As a result, many countries have designed and implemented whole-of-school physical activity initiatives that seek to increase physical activity opportunities that are available to school-aged children before, during, and after school. Considering the comprehensive school physical activity program conceptual framework, this article includes a discussion of the initiatives from four countries: Finland (Finnish Schools on the Move), Ireland (Active School Flag), Poland (PE with Class), and the United States (Let’s Move Active Schools). Background information, implementation strategies, best practices, development opportunities, and relevant research from each country will be presented. Exploring different perspectives sheds some light on the international landscape relative to whole-of-school physical activity promotion and provides direction for future and continued research and practice.     

SCHOOL ANXIETY INVENTORY: RELIABILITY AND VALIDITY EVIDENCE IN A SAMPLE OF SLOVENIAN ADOLESCENTS

The purpose of this study was to examine the reliability and validity of the School Anxiety Inventory (SAI) using a sample of 646 Slovenian adolescents (48% boys), ranging in age from 12 to 19 years. Single confirmatory factor analyses replicated the correlated four‐factor structure of scores on the SAI for anxiety‐provoking school situations (Anxiety about School Failure and Punishment, Anxiety about Aggression, Anxiety about Social Evaluation, and Anxiety about Academic Evaluation), and the three‐factor structure of the anxiety response systems (Physiological Anxiety, Cognitive Anxiety, and Behavioral Anxiety). Equality of factor structures was compared using multigroup confirmatory factor analyses. Measurement invariance for the four‐ and three‐factor models was obtained across gender and school‐level samples. The scores of the instrument showed high internal reliability and adequate test–retest reliability. The concurrent validity of the SAI scores was also examined through its relationship with the Social Anxiety Scale for Adolescents (SASA) scores and the Questionnaire about Interpersonal Difficulties for Adolescents (QIDA) scores. Correlations of the SAI scores with scores on the SASA and the QIDA were of low to moderate effect sizes.     

Measuring the impact of inquiry-based learning on outcomes and student satisfaction

The aim of this study is to determine the impact of inquiry-based learning (IBL) on students’ academic performance and to assess their satisfaction with the process. Linear and logistic regression analyses show that examination grades are positively related to attendance at classes and tutorials; moreover, there is a positive significant relationship between academic performance and IBL, which is considered useful for better understanding of the subject. While students’ satisfaction is directly associated with class attendance and motivation and with the perceived usefulness of IBL, it is unaffected by attendance at tutorials. We conclude, therefore, that students become more involved in learning and acquire increased knowledge of the subject when an IBL-based method is followed.     

Supporting the professional development of teacher educators in a productive way

This study reports on what 13 teacher educators going through a procedure to become registered as a teacher educator in 2011–2012 learned, what goals they formulated for their further professional development and what activities they planned to achieve these goals. The methods used in this study are mainly the same as were used at the time the first cohort went through the registration procedure in 2002. The 2012 cohort participated in a supportive programme, whereas the 2002 cohort did not. This enables a comparison of the results of both studies and thus some insight into the possible benefits of integrating a registration procedure with a supportive programme for the professional development of teacher educators.
