An important component of family life is sexuality education. Being comfortable with one's sexuality is an essential component of individual and family wellness. To this end, parents and teachers who intend to assist in young children's sexuality education must be comfortable and well informed.Nilufer P.

In the present experiment the animation of the operating mechanism of a pendulum clock was used in order to compare the effects of spatial cueing with those of temporal scaling on the comprehension of the animation. The presentation speed of the clock mechanism (normal vs. fast) and signalling cues to three different parts of the mechanism (weight, pendulum, and an irrelevant gear as blinking elements) were used in a 2 × 3 between subjects design with 144 participants. It was found that compared to normal speed condition, understanding was improved in the fast speed condition, but was unaffected by any of the cueing conditions. The results indicate that, although guidance of attention to relevant parts of an animation is often seen as a key to effective instructional design, the way temporal manipulations affect understanding is independent from local attention guiding. 相似文献

What motivates adolescents to cultural participation? This question is important for the discourse on aesthetic education, in which cultural participation is regarded as contributing to the development of adolescents’ personality, values, and competencies. However, research on this issue suffers from fragmentation. Unconnected research on cultural participation from the sociology, cultural education, and differential psychology literature are reviewed, and it is shown how they may be supplemented using the theory of planned behaviour and integrated in a single theoretical framework. This framework centers on cultural participation as a field of person-environment transaction. Participation is regarded as being determined by both person and environmental variables and has the potential of changing these variables. On both its person and its environment sides, the model contains domain-specific determinants that mediate effects of the domain-general variables on which research on cultural participation has focused up to now. An overview of own empirical research related to the model is given and avenues for future research on cultural participation are discussed. 相似文献

In this study, methods for data acquisition, analysis, modelling, and simulation of performance parameters in road cycling on real tracks were developed and evaluated. A simulator was designed to facilitate the measurement in a laboratory environment. The simulation included real height profiles and a video playback that was synchronised with the cyclist’s current virtual position on the track, and online visualisation of course and performance parameters. Field data obtained on mountain tracks in this study were compared with the state-of-the-art mathematical model for road cycling power, established by Martin et al. (J Appl Biomech 14: 276–291, 1998), which accounts for the gradient force, air resistance, rolling resistance, frictional losses in wheel bearings and inertia. The model described the performance parameters accurately with correlation coefficients of 0.96–0.99 and signal-to-noise ratios of 19.7–23.9 dB. It was shown that the mathematical model could be implemented on an ergometer for simulating rides on real courses, providing similar quality measures when comparing field and simulator measurements. 相似文献

Mobile phones and advanced web-based video tools have pushed forward new paradigms for using video in education: Today, students can readily create and broadcast their own digital videos for others and create entirely new patterns of video-based information structures for modern online-communities and multimedia environments. This paradigm shift in video usage can be used for advanced learning about complex topics in higher education, for example, learning about socio-scientific or medical topics. Yet–technology aside–applicable educational concepts using collaborative video creation as a method need to be developed. In the present study, we investigate a specific concept designed to fight obesity stigmatization by developing knowledge using a learning-through-design-approach. We expected that creating videos can actually contribute to a deeper understanding of obesity and to a reduction in stigmatizing attitudes–when compared to a control condition. Dependent measures were based on the students’ video products, obesity-related knowledge and attitudes. The course group assessed their own knowledge on causes of obesity and stigmatization because of obesity higher in the post-test than a control group who read a newspaper article on the topic. A corresponding significant reduction in stigmatizing attitudes was found. In sum, results indicate significant differences between students who produced YouTube videos and a control group of students. The results are interpreted as a confirmation of our initial assumptions and evidence indicating that the program is successfully applicable in higher education. 相似文献

The consequences of central examinations on educational quality standards and labour market outcomes
Central examinations—that is, centrally set and marked exams—have often been discussed as an instrument for improving educational outcomes. The aim of our study was to determine whether central exams have an impact not only on educational but also on labour market outcomes. We explain school quality choice through the incentives created by central exams vs. non‐central exams and model the resulting students’ schooling decisions and employers’ wage decisions. We use the German Abitur and the variation among the German federal states with respect to central exams as a quasi‐experimental design for alternative educational quality regimes. As hypothesised from our theoretical analysis, the percentage of Abitur holders increases more quickly in quality regimes without central exams than with central exams. However, as theoretically expected in the case of a pooled labour market, the wage premium decreases not only for Abitur‐holders without central exams but also for all Abitur‐holders. This is due to the quality deterioration in the states without central exams which spills over into a pooled labour market. Thus, graduates from states with central exams and higher educational standards ‘pay’ for the quality deterioration of educational standards in states without central exams. 相似文献

In this study, we report on the students' evaluation of a self-constructed constructivist e-learning environment for statistics, the compendium platform (CP). The system was built to endorse deeper learning with the incorporation of statistical reproducibility and peer review practices. The deployment of the CP, with interactive workshops and group assignments, immerses students in a novel blended e-learning experience. Based on the Delone and McLean framework, we tested an explanatory success model with a sample of 607 business students, collected during three consecutive academic years. The results indicate that system quality and teacher support are the most important success factors, directly or indirectly contributing to a higher degree of relative advantage and satisfaction, both of which strongly determine continuous intention to use. The findings ascertain the usability and acceptance of the CP and promote a more radical constructivist approach to the teaching of statistics, but also other subjects. 相似文献

AbstractThe study examined the acute neuromuscular and metabolic responses and recovery (24 and 48 h) to combined strength and endurance sessions (SEs). Recreationally endurance trained men (n = 12) and women (n = 10) performed: endurance running followed immediately by a strength loading (combined endurance and strength session (ES)) and the reverse order (SE). Maximal strength (MVC), countermovement jump height (CMJ), and creatine kinase activity were measured pre-, mid-, post-loading and at 24 and 48 h of recovery. MVC and CMJ were decreased (P < 0.05) at post-ES and SE sessions in men. Only MVC decreased in ES and SE women (P < 0.05). During recovery, no order differences in MVC were observed between sessions in men, but MVC and CMJ remained decreased. During recovery in women, a delayed decrease in CMJ was observed in ES but not in SE (P < 0.01), while MVC returned to baseline at 24 h. Creatine kinase increased (P < 0.05) during both ES and SE and peaked in all groups at 24 h. The present combined ES and SE sessions induced greater neuromuscular fatigue at post in men than in women. The delayed fatigue response in ES women may be an order effect related to muscle damage. 相似文献

AbstractThe aim of the study was to evaluate the time required by German Bundesliga soccer teams to recover ball possession – which was operationalised as defensive reaction time – and identify both the differences between top teams and the rest of the league and the influence of match status on the aforementioned indicator. Therefore, teams were classified into 3 distinct groups according to their final league position: top, in-between and bottom. In total, all 306 games of the season 2010/2011 were analysed post-event. Top teams recovered ball possession quickest after losing it in comparison to the other groups and demonstrated lower defensive reaction times (approximately 1 s in each match status) compared to the remaining teams. Moreover, all groups showed the lowest defensive reaction times when trailing. The results of this study imply that recovering ball possession as quickly as possible after losing possession was an important determinant of successful defensive performance in German Bundesliga season 2010/2011. Further, the current score seemed to be highly influential on the defensive reaction time. The implications of the results for future research, especially considering opponent interactions, are critically discussed. 相似文献
