Bridge-building activities are practiced widely in the education systems of Europe. They are meant to bridge transitions between lower and upper secondary school and form a mandatory part of the youth guidance system in Denmark. By giving pupils the opportunity to experience the different educational context of upper secondary school, bridge-building activities are meant to facilitate their decision-making on educational paths, but also to attract more and new groups of pupils. However, the premises of the inherent differences of educational contexts and of pupils’ lacking knowledge of upper secondary education can be questioned. In this ethnographic case study of a bridge-building project in a rural area in Denmark, we analyse the implicit knowledge of the general upper secondary school, as it is practiced in a bridge-building project, and how it is experienced by the pupils on the background of their prior knowledge. The analysis is theoretically informed by especially the code concepts of Basil Bernstein. 相似文献

Four pigeons responded on a two-component multiple token-reinforcement schedule, in which tokens were produced according to
a random-interval 30-sec schedule and exchanged according to a variable-ratio 4 schedule in both components. To assess the
effects of contingent token loss, tokens were removed after every second response (i.e., fixed-ratio 2 loss) in one of the
components. Response rates were selectively lower in the loss components relative to baseline (no-loss) conditions, as well
as to the within-condition no-loss components. Response rates were decreased to a greater degree in the presence of tokens
than in their absence. To control for the effects of changes in the density of token and food reinforcement, two parts consisted
of additional conditions where food density and token loss were yoked to those in a previous loss condition. In the yoked-food condition, tokens were produced as usual in both components, but the overall density of food reinforcement in one of the
components was yoked to that obtained during a previous token-loss condition. In the yoked token-loss condition, tokens were removed during one component of the multiple schedule at a rate that approximately matched the obtained
rate of loss from a previous token-loss condition. Response rates in these yoked components were less affected than those
in comparable loss components, despite similar densities of token, exchange, and food reinforcement. On the whole, the results
support the conclusion that contingent token loss serves as an effective punisher with pigeons. 相似文献

This study investigated changes in teachers' and students' perceptions of students' effort, strategy use, and academic difficulties when strategy instruction was infused into the classroom curriculum. The sample consisted of 201 students with learning disabilities, 210 average achievers, and 57 teachers from Grades 4–9 in two urban and suburban communities. After six months of classroom‐based strategy instruction, students with learning disabilities reported more consistent use of strategies with their schoolwork and perceived themselves as struggling less in reading, writing, and spelling. Teachers perceived the students with learning disabilities as more strategic and as applying more effort to their schoolwork. Teachers also perceived their students as showing significant improvements in spelling, regardless of whether they had learning disabilities. These findings extended the results of previous investigations and indicated the small, positive impact of classroom‐based strategy instruction. Further investigations are critical to evaluate the generalizability of these findings. 相似文献

This article reports the results of a survey that analyzed the job satisfaction of 361 library access services practitioners. Library access services staff were surveyed and asked to rate job satisfaction based on Maslow's Hierarchy of Needs and Herzberg's Two-Factor Theory. Results show that access services staff have opportunities for satisfaction based on higher-level needs. Personal fulfillment, job opportunities, and relationships with coworkers rated as the top three most important factors. There are also contributing factors that affect job satisfaction based on lower-level needs, such as salary. Age, education level, and administrative responsibilities also play a role in job satisfaction of access services staff. The survey results demonstrated that most employees are satisfied, while improvements are needed in certain areas to provide employees with a more fulfilling work environment. 相似文献

Using data from the Educational Longitudinal Study of 2002–2006, the authors investigated the effects of advanced math course taking on math achievement and college enrollment and how such effects varied by socioeconomic status and race/ethnicity. Results from propensity score matching and sensitivity analyses showed that advanced math course taking had positive effects on math achievement and college enrollment. Results also demonstrated that the effect of advanced math course taking on math achievement was greater for low socioeconomic status students than for high socioeconomic status students, but smaller for Black students than for White students. No interaction effects were found for college enrollment. Limitations, policy implications, and future research directions are discussed. 相似文献
