通过一个2(成功与否)×2(提示与否)×2(题型)的混合实验设计,对小学五年级学生解决和差应用题的表征策略进行了研究.结果表明:(1)与比较应用题的表征相类似,小学生对和差应用题的表征也存在着直译策略和问题模型策略;(2)不成功组解题者在表征和差应用题时倾向于运用直译策略,而成功组的解题者更倾向于运用问题模型策略,这导致了成功者与不成功者在列式上的差异,特别是在不一致题型上表现得更明显;(3)在读题前给以“请注意理解这道题的意思”这样简单的提示,对不成功的解题者对和差问题的正确表征并不能起到作用;(4)成功的和差应用题解题者和不成功的解题者在列式正确性的自我评价上存在显著差异. 相似文献

The effectiveness of a simultaneous prompting procedure was evaluated in a heterogeneous small group using different tasks and different stimuli for each student. Participants included four middle school students whose functioning levels ranged from typically developing to moderate and severe disabilities. A multiple probe design across behaviors and replicated across students was used. Observational learning maintenance, and generalization also were assessed. Results indicate that the procedure was successful in teaching all four students their targeted stimuli as well as some of the non-targeted stimuli (i.e., observational learning). Students maintained and generalized their information with a high degree of accuracy. Limitations of the study and future research implications are discussed. 相似文献

To design effective and socially sensitive systems, engineers must be able to integrate a technology-based approach to engineering
problems with concerns for social impact and the context of use. The conventional approach to engineering education is largely
technology-based, and even when additional courses with a social orientation are added, engineering graduates are often not
well prepared to design user- and context-sensitive systems. Using data from interviews with three engineering students who
had significant exposure to a socially-oriented perspective on production systems design, this paper argues that engineering
students may have difficulty integrating in their own practice the technology-based and the socially-oriented perspectives
on production. To enhance engineering students' ability to create systems that integrate both perspectives, and to relieve
the intense cognitive and emotional pain that can be experienced by students exposed to both perspectives but unable to reconcile
them, this paper reinforces the importance of teaching students the meta skill, design. A design perspective can help students integrate varied, sometimes conflicting, perspectives, and reach beyond customer-defined
constraints to consider workplace and social impact. 相似文献

Two experiments investigated the effects of shifting from either nonreinforcement or partial reinforcement (PRF) to continuous reinforcement conditions (CRF). In the first experiment, three groups of rats were given food reinforcement under CRF conditions in a runway followed by regular extinction trials (RE), extinction trials where Ss were delayed for 30 sec before entering the empty goal box (DE), or CRF trials where Ss were delayed for 30 sec before entering the baited goal box (DF). Then all Ss were run on the delayed reinforcement condition (DF). In the final delayed reinforcement condition, group DE ran significantly faster than group DF, reflecting positive contrast. In the second experiment, four groups of rats were trained in a runway to receive either 4% or 18% sucrose reinforcers under either PRF or CRF conditions. Then all Ss were transferred to a Skinner box and bar presses were continuously reinforced, with each S continuing to receive the same sucrose concentration as before. The former PRF Ss, regardless of the reinforcer, bar pressed at a significantly higher rate in the Skinner box than the former CRF Ss. The evidence seemed to favor the view that the effectiveness of a reinforcer is not an absolute, unchanging quantity but rather depends on the historical context in which the reinforcer occurs. 相似文献

This study explores the role of perceived internal and external career barriers on undergraduates' vocational outcomes, such as academic major satisfaction and vocational identity commitment. Moreover, it tests career adaptability as a moderator in the barriers-vocational outcomes link. The study was carried out in three public universities in Lithuania. In total, 288 first and second year undergraduate students took part in it. Results demonstrated internal but not external barriers to be negatively associated with undergraduates' vocational outcomes. 相似文献

Emotion Regulation and Coping Strategies in Pedagogical Students with Different Attachment Styles 下载免费PDF全文
Abstract : Emotion regulation (ER) and coping strategies were compared in 242 pedagogical students from the Faculty of Education, University of Ljubljana, with different attachment styles: secure (51.3%), fearful (31.9%), preoccupied (14.2%), and dismissive (2.7%). The students’ ages ranged from 18 to 24 years ( M = 19.02; SD = .92), and the majority were female (95.0%). They completed three questionnaires assessing their attachment styles and their use of ER and coping strategies. It was determined that the students used the majority of ER and coping strategies sometimes. Somewhat different patterns in the use of ER and coping strategies were, however, present in each attachment‐based group. Significant differences between these groups appeared in their use of the ER strategies of social support, suppression, and comfort eating, and in the coping strategies of seeking social support and escaping or avoiding stressful situations. 相似文献
