The study reexamines the effect of delayed reinforcement upon contingency behavior in 6- to 8-month-old infants and attempts to account for the temporal discrepancy between span of integration and contingency memory. A modified delayed-reinforcement scheduling procedure enabled a previous methodological criticism to be discounted. The findings confirmed that whereas infants revealed reliable acquisition under immediate reinforcement, a 3-sec delay (whether reset or nonreset) precluded response acquisition, as did 6-sec and 10-sec delay of reinforcement. The findings are interpreted in terms of an informational-load hypothesis which relates short-term memory to the integration and/or segregation of multimodal input.  相似文献

This paper identifies key factors affecting conceptual gains from using a CAL package and their application to a practical laboratory class. Data was collected on over 120 first year students who studied a CAL package as an integral part of their course at two sites of a university. A variety of factors were analysed in order to identify which ones affected conceptual gains. These factors were students' biographical characteristics, design features of the CAL package and the way the CAL was integrated into the curriculum. The key factors that were identified as having an effect on conceptual gains were the students' prior academic attainment, their prior use of email, the WWW and CAL packages, and the way that the CAL package was integrated into the course. Those students, who were most successful in learning from the CAL and applying this learning, had higher academic attainment and had previously used the WWW, email and other CAL packages. They were also better at linking their study of the CAL package to other parts of the course.  相似文献

We investigated what factors would be related to students' achievement in mathematics courses offered at a virtual high school. This was an attempt to understand why some succeed and some do not as well as to suggest what should be done to help with student success. Seventy‐two students responded to a self‐report survey on motivation (ie, self‐efficacy, intrinsic value), mathematics achievement emotions (ie, anxiety, anger, shame, hopelessness, boredom, enjoyment, pride), and cognitive processes (ie, cognitive strategy use, self‐regulation). A three‐step hierarchical multivariate regression was employed to examine which of the factors predict student achievement. Results showed that motivation accounted for approximately 13% of the variance in student achievement and self‐efficacy was the significant individual predictor of student achievement. However, when achievement emotions were added to the analysis, self‐efficacy failed to predict student achievement and emotions accounted for 37% of the variance in student achievement. Cognitive strategy use and self‐regulation did not explain any additional variance in the final scores. Findings are discussed and implications for future research and development are also suggested.  相似文献

This paper reports the activity of three secondary school mathematics departments in England in self-initiated states of change that led to overall improvements in students’ achievements when compared to previous cohorts. This took place without intervention and without their participation in external projects. They provide examples of departments that can work effectively on their own development, and hence, their work adds to our knowledge of the potential for development through collaboration. The departments were monitored over 3 years, and data were analysed using the lens of activity theory. In contrast to departments in many studies, these departments worked overtly on mathematics pedagogy through the shared production and discussion of resources, shared planning and task design. Also in contrast to several other studies, they developed distinct ways to handle differences of subject knowledge among the teachers in the department. Their focus changed during the study from developing resource banks to supporting students’ learning through hybrid teaching.  相似文献

Institutionalised discrimination continues to perpetuate deep rooted social divisions, with gender inequality persisting as a pervasive feature of labour markets across the world. Despite the depth and breadth of gender inequality, there is limited acknowledgement in career theory that the career support needs of women are distinctive. A qualitative international comparative study into the career trajectories of older women (aged 45–65) has been conducted across six countries (Australia, Argentina, Germany, Italy, England and South Africa). The results provide an international understanding of women’s careers and offer insight into career theory and practice for women that are culturally relevant.  相似文献

OBJECTIVE: To identify reliable, inexpensive predictors of foster care placement disruption that could be used to assess risk of placement failure. METHODS: Using the Parent Daily Report Checklist (PDR), foster or kinship parents of 246 children (5-12 years old) in California were interviewed three times about whether or not their foster child engaged in any of the 30 problem behaviors during the previous 24 h. PDR was conducted during telephone contacts (5-10 min each) that occurred from 1 to 3 days apart at baseline. Disruptions were tracked for the subsequent 12 months. Other potential predictors of disruption were examined, including the child's age, gender, and ethnicity, the foster parent's ethnicity, the number of other children in the foster home, and the type of placement (kin or non-kin). RESULTS: Foster/kin parents reported an average of 5.77 child problems per day on the PDR checklist. The number of problem behaviors was linearly related to the child's risk of placement disruption during the subsequent year. The threshold for the number of problem behaviors per day that foster and kinship parents tolerated without increased risk of placement disruption for these latency-aged children was 6 or fewer. Children in non-kin placements were more likely to disrupt than those in kinship placements. There was a trend for increased risk of disruption as the number of children in the home increased. CONCLUSIONS: The PDR Checklist may be useful in predicting which placements are at most risk of future disruption, allowing for targeted services and supports.  相似文献

This article highlights a theoretical and practical framework for integrating the neuropsychological concept of autobiographical memory with the experiential learning that takes place in the outdoors. Autobiographical memories, our recollections of specific, personal events, are constructed through a personal narrative process; the way we choose to tell the stories of our lives, to ourselves, and crucially to others. Our interdisciplinary framework suggests that the participant comes to value memories of particular past events because they come to be seen as part of a shared history with others. Elements of outdoor activities can aid in the formulation of personal narratives and the generation of autobiographical memories. Our case study of a person with congenital deafblindness shows that taking an outdoor education approach can aid in providing shared authentic memorable experiences and in facilitating the construction of autobiographical memories in the bodily tactile modality.  相似文献
