Assessing the effectiveness of a hybrid-flipped model of learning on fluid mechanics instruction: overall course performance,homework, and far- and near-transfer of learning

To examine the impact of a hybrid-flipped model utilising active learning techniques, the researchers inverted one section of an undergraduate fluid mechanics course, reduced seat time, and engaged in active learning sessions in the classroom. We compared this model to the traditional section on four performance measures. We employed a propensity score method entailing a two-stage regression analysis that considered eight covariates to address the potential bias of treatment selection. First, we estimated the probability score based on the eight covariates, and second, we used the inverse of the probability score as a regression weight on the performance of learners who did not select into the hybrid course. Results suggest that enrolment in the hybrid-flipped section had a marginally significant negative impact on the total course score and a significant negative impact on homework performance, possibly because of poor video usage by the hybrid-flipped learners. Suggested considerations are also discussed.     

Long-term retention of fear-potentiated startle following a short training session

The permanence of aversive memories has been reported to vary when assessed with conditioned emotional response procedures (months) versus avoidance response measures (days). When evaluated with the potentiated startle paradigm, five light-shock pairings at a 2-min intertrial interval produced highly reliable potentiated startle, which was similar in magnitude from 1 to 28 days after training and maximal using a 0.6-mA footshock intensity. These results are consistent with such measures as conditioned emotional response procedures, in which aversive memories have been observed after months following originaltraining. The results obtained with various shock intensities are also discussed in the context of other indices of fear.     

‘Christian Patriotism’ and Physical Education in Pre-Revolutionary France: The Royal Military School in Sorèze in the Eighteenth Century

The Ecole Royale Militaire of Soreze (Royal Military School) was located in the French province of Languedoc. On the eve of the 1789 Revolution it was still a religious institution run by the Benedictine monks, known for having broken with certain traditional models. The establishment offered special forms of instruction, stressing certain scientific and literary disciplines, and also physical education (fencing, dancing, horse riding, and equestrianism). Pupils’ best results were also recorded in swimming. At the end of every school year, all the results were confirmed by public examinations, labelled Exercices publics, and recorded in the Cahiers d’exercices. These materials enable the reconstruction the evolution of the school’s programmes over a period of more than a century. The incalculable richness of Sorèze’s programmes, by distinguishing the elements already present in the military training of the period from the pedagogical innovations that were introduced, demonstrate the special place that was reserved for physical exercise. This Catholic institution was thus able to develop a total coherence of the scholarly programme, considered as a source of ‘Christian Patriotism’, in pre-Revolutionary France.     

Tour de France,Giro, Vuelta,and classic European races show a unique progression of road cycling speed in the last 20 years

Abstract

Road cycling ranks among the most intense endurance exercises. Previous studies and mathematical models describing road cycling have not analysed performances per se. We describe the evolution of road cycling performance over the past 116 years. We studied the top ten cyclists' mean speeds in eight famous classic races and three European Grand Tours, using a previously published multi-exponential model that highlights the different progression periods of an event during the century. In addition, we measured an indicator of difficulty for the Tour de France by calculating the climbing index (i.e. the total altitude climbed over total distance). The eleven races' mean speed increased progressively from 23.13 km · h^?1 in 1892 to 41.19 ± 2.03 km · h^?1 in 2008. Road cycling development, like other quantifiable disciplines, fits a piecewise progression pattern that follows three periods: before, between, and after the two World Wars. However, a fourth period begins after 1993, providing a speed progression of 6.38% from the third one. The Tour de France's climbing index also provided insight into a recent paradoxical relationship with speeds: when the climbing index increased, the winner's speed also increased. Our results show a major improvement (6.38%) in road cycling performance in the last 20 years and question the role of extra-physiological parameters in this recent progression.     

Triadic Supervision and its Impact on the Role of the Supervisor: A Qualitative Examination of Supervisors' Perspectives

Although triadic supervision has been the subject of little empirical research, perspectives of supervisors in this form of supervision have received even less attention. This qualitative study examined 6 doctoral student supervisors' experiences of triadic supervision and the demands it placed on them in their role as supervisors. Data collection involved use of in‐depth, open‐ended interviews, and a whole‐text analysis resulted in 2 major categories. These categories address various ways in which triadic supervision increases or decreases the demands placed on the supervisor. Implications of the findings for supervisory practices and future research are also addressed.     

Are intensified physical education sessions able to elicit heart rate at a sufficient level to promote aerobic fitness in adolescents?

The purpose of this study was to determine the effects of intensified physical education sessions on adolescents ages 11-16 years. They were divided into two experimental groups--high-intensity running group (HIRG) and high-intensity jumping group (HlJG)--and a control group (C). During the sessions, heart rate (HR) was monitored. There was no significant difference between mean HR for HIRG and HIJG, while the mean HR was significantly lower for C (p < .001). For both HIRG and HIJG, the mean HR was significantly higher for girls than for boys (p < .001). Our results suggested that these intensified physical education lessons require a high percentage of maximal HR in adolescents and can be used to improve aerobic fitness.
