Research has shown the importance of students’ perceptions of a learning environment and the existence of discrepancies between students’ and teachers’ perceptions. Participatory design could be a helpful strategy to reduce such discrepancies and eventually improve the design of learning environments, as it has proven to be effective to optimize design in other domains. The current study investigated the desirability and feasibility of possible use of participatory design in education. Students and teachers in secondary education were interviewed about their opinions on the idea of participatory design of a learning environment. Both students and teachers displayed predominantly positive opinions towards possibly engaging in participatory design, supporting its desirability and feasibility. Practical suggestions for implementation are included. 相似文献

Although approach forms of achievement goals (mastery and performance goals) have been shown to predict academic achievement in college, recent research underscores that these associations are rather weak and not consistently observed. The present study tests students’ social class (in the present research, generational status) as a moderator of the relationships between both mastery-approach goals and performance-approach goals and final grade. One hundred students (45 first-generation students and 55 continuing-generation students, M age = 18.9, SD = 1.52) answered an achievement goal scale related to one of their classes at the beginning of the year. Their final grade for this class was obtained three months later. As expected, performance-approach goals positively predicted final grade only for upper-class students, while mastery-approach goals tend to do so for lower-class students, supporting the idea that different kinds of motivation could predict students’ achievement depending on their social class. 相似文献

Four‐ to Six‐Year‐Old Children's Sensitivity to Reliability Versus Consensus in the Endorsement of Object Labels 下载免费PDF全文
Recent studies have demonstrated that young children use past reliability and consensus to endorse object labels. Until now, no study has investigated how children weigh these two cues when they are in conflict. The two experiments reported here were designed to explore whether any initial preference for information provided by a consensual group would be influenced by the group's subsequent unreliability. The results show that 4‐ and 5‐year‐old children were more likely to endorse labels provided by an unreliable but consensual group than the labels provided by a reliable dissenter. Six‐year‐olds displayed the reverse pattern. The article concludes by discussing the methodological implications of the two experiments and the developmental trajectory regarding the way children weigh consensuality versus reliability. 相似文献

This study was conducted at a small ‘research-led’ institution in South Africa. The data indicate that women produce less research than men and have low levels of professional self-esteem. Factors such as accrual of social capital, family responsibilities and self-esteem are constraints experienced by women academics in pursuing research careers. Mentoring was found to facilitate research career development and improve levels of self-esteem. Improved self-esteem enables women to promote themselves within their institutions and in the research arena. The role of the head of department with mentoring as a key function emerged as an influential structure for the career advancement of women academics. However, these leadership positions are significantly dominated by men and this appears to affect the amount and nature of mentoring women academics receive. 相似文献

We analyze a recently introduced approach for the sorting of aqueous drops with biological content immersed in oil, using a microfluidic chip that combines the functionality of electrowetting with the high throughput of two-phase flow microfluidics. In this electrostatic sorter, three co-planar electrodes covered by a thin dielectric layer are placed directly below the fluidic channel. Switching the potential of the central electrode creates an electrical guide that leads the drop to the desired outlet. The generated force, which deflects the drop, can be tuned via the voltage. The working principle is based on a contrast in conductivity between the drop and the continuous phase, which ensures successful operation even for drops of highly conductive biological media like phosphate buffered saline. Moreover, since the electric field does not penetrate the drop, its content is protected from electrical currents and Joule heating. A simple capacitive model allows quantitative prediction of the electrostatic forces exerted on drops. The maximum achievable sorting rate is determined by a competition between electrostatic and hydrodynamic forces. Sorting speeds up to 1200 per second are demonstrated for conductive drops of 160 pl in low viscosity oil. 相似文献

Penalty takers in association football adopt either a keeper-independent or a keeper-dependent strategy, with the benefits of the keeper-independent strategy presumed to be greater. Yet, despite its relevance for research and practitioners, thus far no method for identifying penalty kick strategies has been available. To develop a validated and reliable method, Experiment 1 assessed characteristics that observers should use to distinguish the two strategies. We asked participants to rate 12 characteristics of pre-recorded clips of kicks of penalty takers that used either a keeper-independent or keeper-dependent strategy. A logistic regression model identified three variables (attention to the goalkeeper, run-up fluency and kicking technique) that in combination predicted kick strategy in 92% of the penalties. We used the model in Experiment 2 to analyse prevalence and efficacy of both the strategies for penalty kicks in penalty shoot-outs during FIFA World Cups (1986–2010) and UEFA Football Championships (1984–2012). The keeper-independent strategy was used much more frequently (i.e., 78–86%) than the keeper-dependent strategy, but successes did not differ. Penalty takers should use both the strategies to be less predictable. Goalkeepers can use the developed model to improve their chances to succeed by adjusting their behaviour to penalty takers’ preferred penalty kick strategy. 相似文献
