Between-Day Reliability and Usefulness of a Fitness Testing Battery in Youth Sport Athletes: Reference Data for Practitioners

This study aimed to evaluate the between-day reliability and usefulness of a fitness testing battery in a group of youth sport athletes. Fifty-nine youth sport athletes (age = 17.3 ± 0.7 years) undertook a fitness testing battery including the isometric mid-thigh pull, counter-movement jump, 5–40 m sprint splits, and the 5–0-5 change of direction test on two occasions separated by 7 days. Usefulness was assessed by comparing the reliability (typical error) to the smallest worthwhile change. The typical error was 5.5% for isometric mid-thigh pull and 3.8% for counter-movement jump. The typical error values were 2.7, 2.5, 2.2, 2.2, and 1.8% for the 5, 10, 20, 30, and 40 m sprint splits, and 4.1% (left) and 5.4% (right) for the 5–0-5 tests. The smallest worthwhile change ranged from 1.1 to 6.1%. All tests were identified as having “good” or “acceptable” reliability. The isometric mid-thigh pull and counter-movement jump had “good” usefulness, all other tests had “marginal” usefulness.     

Finite element simulation of pole vaulting

Pole vaulting is one of the most spectacular disciplines in athletics. The evolution of world record heights is strongly influenced by the development of advanced poles and subsequent materials. Employing advanced, load-adjusted composites has resulted in a steady increase of the world record height. This study provides a framework for finite element simulations of pole vaulting with focus on the initial and boundary conditions as well as finite element choices. The influence of the pole bending stiffness on the achievable height is systematically simulated. Higher effective bending stiffness leads to higher pole vaulting heights. However, if a certain stiffness is exceeded, the vaulter will not be able to bend the pole enough which leads to failed attempts.     

Analysepotenziale des Sozio-oekonomischen Panels (SOEP) für die empirische Bildungsforschung

In Germany, the main datasets available for addressing empirical educational research questions are cross-sectional data, which are often supplemented by state-specific or group-specific longitudinal surveys. The latter are usually focused on specific transitions in the educational system. The challenge of an approach to educational research that takes the perspective of life-course theory, however, lies in analyzing educational and competency development across the entire life span and the dependence of these processes on institutional and individual environment contexts. The present paper shows the opportunities that the Socio-Economic Panel (SOEP), a household and individual survey now running for over 25 years, offers for empirical educational research aimed at confronting such research challenges. In addition to outlining the available educational information and methodological innovations in the SOEP’s education-related survey program, we also describe the survey’s comparative strengths, particularly for educational analyses stretching ‘from the cradle to the grave’ and dealing with intergenerational and familial contexts.     

Ergebnisse nationaler und internationaler Forschung zu schulischen Innovationsnetzwerken

Accompanied by the increasing relevance of school networks, there are a lot of reports available in national and international research regarding this topic. However, a compact summary of those studies and their findings is missing by now. Therefore, this article synthesizes the current research on school networks. Starting with the introduction of theoretical concepts for a better understanding of academic innovation networks, the article examines the empirical findings concerning those networks. This examination is conducted separately for German language and English language research. According to the presented findings, a consistent positive effect of school networks can be traced. The article concludes with a discussion of future research potentials concerning networks. Concrete suggestions for methodical and theoretical designs regarding network research are submitted.     

Australian adolescent boys with attention deficit/hyperactivity disorder (AD/HD): teacher and teaching factors that assess the efficacy of reducing unwanted behaviours within the classroom environment

Students with AD/HD experience difficulty concentrating in the classroom due to unwanted behaviours. This article focuses on what six Australian adolescent boys have to say about teacher and teaching factors that enabled them to regain focus (if distracted) and concentrate on classroom learning. A multiple, instrumental case-study was used to collect data from the boys using semi-structured individual and focus group interviews as well as school reports across a two year period. Findings suggested that interventions including frequent short breaks, humour by the teacher and teachers who operate in a well-structured classroom and who know their subject matter well, were beneficial in reducing unwanted behaviours and resulted in less negative events, thereby making schooling a more positive experience.     

Motivational decline and recovery in higher education STEM courses

Decline in student motivation is a concern for STEM education, especially for underrepresented groups in the sciences. Using the Science Motivation Questionnaire II, 41 foundational STEM courses were surveyed at the beginning and end of each semester in an academic year at a small primarily undergraduate university. Significant pre- to post-semester declines were observed in each of five measured motivational factors (Intrinsic motivation, Career motivation, Self determination, Self-efficacy, and Grade motivation), with effect sizes ranging from 0.21 to 0.41. However, in the second semester pre-survey, four motivational factors rebounded, including three returning to initial levels, suggesting that the observed motivational decline is not long-lasting. Analysis suggests that declines are not related to survey fatigue or student demographics, but rather to grades and, in the case of one motivational factor, to academic field. These findings suggest that a refocus on grading practices across STEM fields may influence student motivation and persistence in STEM.
