This study examines the contributions of temperamentally and nontemperamentally based emotional reactions to the organization of social interactive behavior within the Strange Situation to better understand the emotional underpinnings of attachment system functioning. At 12 1/2 and 19 1/2 months, temperamental fear (assessed via maternal report) was related to independent per-episode dimensions of social interactive and distress behavior. Fear was moderately correlated with both distress and interactive dimensions at each age. Path-analytic models revealed that temperamental fear had direct effects on interactive behavior and also indirect effects mediated by preceding distress reactions. However, residualized measures of "context-specific" distress (with temperamental variance removed) were still highly consistent across Strange Situation episodes and also significantly predicted subsequent social interactive behavior; furthermore, stable distress reactions from 12 1/2 to 19 1/2 months significantly predicted concurrent stability in social interactive behavior. We discuss likely sources of "context-specific" emotional influences on Strange Situation behavior and also age-related differences in these findings.  相似文献

This paper reports an experimental study into the effects of cooperative and individualistic approaches in teaching Mathematics and English. The study was conducted at a Vacation Learning Camp (VLC) which was held for two weeks in one of the secondary schools in Singapore. This VLC was targeted at Secondary One pupils who were classified as below average based on general ability streaming.

The individualistic teaching approach was assumed to contribute to individual efforts while the cooperative teaching approach was expected to produce cooperativeness among the subjects. The results indicated that there were no significant differences in performances in the main effects classified as the treatment groups and the sex groups in both Mathematics and English; in Mathematics, the individualistic teaching approach was more effective for the male pupils whereas the cooperative teaching approach was more effective with females. However, in English, the results were reversed.

The female pupils in the cooperative group seemed to have improved in their attitude towards learning Mathematics whereas the male pupils in the individualistic group seemed to have a more positive attitude towards learning English.  相似文献

Mastery learning, it is claimed, is among the most successful practices in higher education. Evidence supporting this claim has recently been criticized as empirically weak. This experiment employed a four-group, pre-post design to examine the learning consequences of a computer-administered mastery-testing approach in comparison with a seminar-discussion approach in a third-year university course. The mastery-testing approach generated significantly higher learning achievement than did the seminar-discussion approach. Replication and extension of this research approach are recommended to support generalizations across mastery-testing techniques, delivery systems, and disciplines.  相似文献

Abstract

In Scotland, and particularly with regards to non-denominational RE, known as Religious and Moral Education (RME), a current focus of debates is on how and why practitioners are implementing or deviating from legal and curricular expectations. Using the findings of a small-scale qualitative practitioner enquiry centered on one local education authority in Scotland, this article advances recent discussions and engages with comparative international scholarship by identifying the challenges and opportunities in relation to the provision of RME and arguing that practitioners are motivated by the demands of learners and the priorities of school leaders, rather than official expectations.  相似文献

This study employed a qualitative research design to investigate how instructional designers use evaluation in everyday design practice. While past research has examined how designers spend their time, how they generally make decisions, and expert-novice differences, little attention has been paid to use of context, input, process, or product evaluation, from the perspective of practicing designers. Based on interviews of practitioners, our findings included ten themes regarding how designers use evaluation to improve their products. While these results substantiate to some degree the claim that practitioners believe clients will not pay for formal evaluations, they also suggest that practitioners use evaluation in important but less formal ways. Other conclusions regarding the role of evaluation in design are provided and future directions for training and research are discussed.  相似文献

This study examined the impact of computer simulation and supported science learning on a teacher’s understanding and conceptual knowledge of current electricity. Pre/Post tests were used to measure the teachers’ concept attainment. Overall, there was a significant and large knowledge difference effect from Pre to Post test. Two interesting interactions were observed during the data analysis. The first was the difference between Elementary and Secondary teachers. Both groups had significant gains, with large effect sizes, but the Elementary teachers (Pre-Mean = 3.70, Post-Mean = 7.51) started lower and ended higher exhibiting a significantly larger gain than the Secondary teachers (Pre-Mean = 4.96, Post-Mean = 6.71). The second interaction was the impact of gender. Both groups showed significant gains, with large effect sizes, but females (Pre-Mean = 3.90, Post-Mean = 7.21) gained significantly more than males (Pre-Mean = 5.13, Post-Mean = 7.01). These results confirm that computer simulation supported science learning can have a positive effect on concept attainment in teachers.  相似文献

Pigeons pecked on three keys, responses to one of which could be reinforced after 3 flashes of the houselight, to a second key after 6, and to a third key after 12. The flashes were arranged according to variable-interval schedules. Response allocation among the keys was a function of the number of flashes. When flashes were omitted, transitions occurred very late. Increasing flash duration produced a leftward shift in the transitions along a number axis. Increasing reinforcement probability produced a leftward shift, and decreasing reinforcement probability produced a rightward shift. Intermixing different flash rates within sessions separated allocations: Faster flash rates shifted the functions sooner in real time, but later in terms of flash count, and conversely for slower flash rates. A model of control by fading memories of number and time was proposed.  相似文献
