Different durations within the method of best practice affect the parameters of the speed–duration relationship

The aim of the study was to determine whether estimates of the speed–duration relationship are affected using different time-trial (TT) field-based testing protocols, where exhaustive times were located within the generally recommended durations of 2–15?min. Ten triathletes (mean?±?SD age: 31.0?±?5.7?years; height: 1.81?±?0.05?m; body mass: 76.5?±?6.8?kg) performed two randomly assigned field tests to determine critical speed (CS) and the total distance covered above CS (D?). CS and D? were obtained using two different protocols comprising three TT that were interspersed by 60?min passive rest. The TTs were 12, 7, and 3?min in Protocol I and 10, 5, and 2?min in Protocol II. A linear relationship of speed vs. the inverse of time (s?=?D??×?1/t?+?CS) was used to determine parameter estimates. Significant differences were found for CS (p?=?0.026), but not for D? (p?=?0.123). The effect size for CS (d?=?0.305) was considered small, while that for D? was considered moderate (d?=?0.742). CS was significantly correlated between protocols (r?=?0.934; p?D? (r?=?0.053; p?=?0.884). The 95% limits of agreement were ±0.28m?s^?1 and ±73.9?m for CS and D?, respectively. These findings demonstrate that the choice of exhaustive times within commonly accepted durations results in different estimates of CS and D?, and thus protocols cannot be used interchangeably. The use of a consistent protocol is therefore recommended, when investigating or monitoring the speed–duration relationship estimates in well-trained athletes.     

Refining measurements of social and academic integration: lessons from a German University of Applied Sciences

A variety of studies have shown that social and academic integration are important indicators of future student success and satisfaction. They are therefore an important field of action for higher education development programmes. However, specifications of the theoretical models and empirical representations vary widely between researchers and countries. We reviewed the most important German and international questionnaires and studies on the topic. On the basis of this review as well as theoretical reflections, we developed a questionnaire which was successfully tested for validity.

     

A cross-cultural comparison of German and Canadian student teachers’ assessment competence

ABSTRACT

Teachers’ competence in educational assessment is a key feature in teacher professionalism. Understanding of assessment competence has evolved from the learning of technical skills in assessment to a context-dependent, socially defined understanding encompassing a multitude of approaches to assessment. Thus, a holistic approach to assessment competence is used in this research to specifically consider the role of education culture on assessment competence. In particular, we compared Canadian and German student teachers with regard to their self-rated competence in, and approaches towards, educational assessment. While structural analysis revealed that the overall dimensions in which assessment is perceived do not depend on culture, ANOVAs pointed at some differences between the two countries, particularly concerning assessment purposes and approaches to fairness.
