The Family Walk-In Centre opened November 1978 as a pilot project at Eaton Socon in Cambridgeshire with the aims: to encourage parents to visit the centre on “their terms,” including parents who have abused or who fear they will abuse or neglect their child who may be difficult or handicapped, or because of chronic or acute family problems; further to mobilize “Self Help” groups and offer professional support. “Help” offered to the families included informal and formal group work, family casework and education in social and physical skills. Volunteer and professional support was given at the Centre and at home. Close liaison with specialist agencies was maintained to enable families to receive appropriate help. Periodic reviews and visits were made to maintain contact. An analysis of 50 families who attended the Centre between October 1979 and May 1980 was made to assess: the attendance and reattendance rate which indicated their acceptance of help offered and their motivation to use the Centre; the types of problems presented to the Centre, the types of action taken, the progress made when reviewed after three months and the degree of involvement by the volunteers. A final analysis will comprise 100 families. A preliminary summary found: significant reduction in the registration of new cases of child abuse; self-referrals exceeded significantly other modes of referral; loneliness and parenting difficulties formed the major proportion of families seeking help; 48% of families continued to attend for 3 months or more; work done centered upon discussion of parenting problems in 30% of the cases and involvement in activities with other families in 28%; 18% were assessed as showing improved child care after 3 months. The children are being monitored and will be assessed when they enter the infant school.  相似文献

The rationale was to apply Piaget’s theory and methods to the study of the phylogenetic development of cognitive abilities. It was asked whether squirrel monkeys have the prerequisite skills for conservation of quantity, and, specifically, whether they might respond differentially to equivalent and unequivalent volumetric cues. All monkeys responded significantly and differentially to pairs of identical objects or pairs of objects similar only in volume vs. pairs of objects which differed in volume. It was concluded that squirrel monkeys have the prerequisite skills for the conservation of quantity. Discussion included methodological problems associated with demonstrating conservation in nonhumans as well as the potential usefulness of Piaget’s theory for phylogenetic studies of intelligence.  相似文献

This study explored the use of Exit Cards, which are formative evaluations of student knowledge and instruction undertaken at every class meeting. Its results are based on Exit Card data from two undergraduate research methods courses. Thematic analysis indicated that students used Exit Cards to communicate (1) what they learned, (2) challenges with course material, (3) experiences with peers, (4) requests for help, (5) challenges with coping, and (6) successes. While the present study is an initial exploration of the use of Exit Cards, it contributes to knowledge on the utilization of informal formative assessments.  相似文献

The purpose of this study was to determine whether criminal thinking interacts with the rational requirements of human decision-making in a group of college students. A convenience sample of 315 undergraduates (114 males, 201 females) completed self-report measures of criminal thinking and estimated their likelihood of cheating on an exam given different levels of certainty of apprehension. A repeated-measures analysis of covariance revealed that students were significantly more likely to seize on the opportunity to cheat when the certainty of getting caught was 10% than when it was 50% and that students with higher levels of criminal thinking were more likely to take the opportunity to cheat than students with lower levels of criminal thinking. In addition, students exhibiting moderate proactive criminal thinking and moderate to high reactive criminal thinking were significantly less likely to be deterred from cheating when the odds of getting caught were low.  相似文献

We examined the implementation of a laser-disk based science curriculum in an elementary school. The goal was to develop a richer understanding of the principles for designing a curriculum that will adequately support teachers in adopting a learner-centered framework. Issues included: who has ownership of the classroom discussion; what types of activities are engaged in terms of the constraints imposed; and what is the teacher's response to the specific tools provided (the teacher's guide, the Circle of Learning, and concept maps). In addition to looking at the implementation pattern, we also examined the impact of the implementation on student attitudes and anxiety toward science. Results indicated little adoption of the curriculum, and teachers continued to maintain a high degree of control in the classroom. However, results also indicated significant effects of the curriculum on science attitude and anxiety. Suggestions for future research are included.  相似文献

Recent research into composing processes has focused on instructional intervention strategies that promote effective composition practices within computerized writing environments. The field of computers and composition has benefitted both from advances in computing tools and developments in learning theory. The innovative computer tool discussed in this paper uses the macro-command language of a full-featured word processor to enact strategic support designed to help writers with their written work. From a theoretical standpoint, this tool created a writing environment based on Vygotskian theory of mediated learning and was grounded in an instructional strategy known as “procedural facilitation.” To evaluate the effectiveness of this computerprompting tool, a second macro application was used to log student keystrokes, thereby tracking student writing development, revisionary practices, and keystroke reactions to the prompting partner. Students using the prompting tool enacted divergent and convergent thinking assistance that appeared at the bottom of their computer screens while the system saved a process record of their keystrokes. Procedures for creating macro-driven prompting programs and keystroke-logging devices are discussed. Additionally, a catalog of prompts and summary of keystroke-mapping benefits are provided. Finally, our research using the macro-driven prompting partner and keystroke-register tool is detailed.  相似文献

Pigeons were trained on two independent tasks. One involved red and yellow hues, the other involved blue and green hues. For half of the birds, the two tasks were the same (i.e., both tasks were either matching-to-sample, or oddity-from-sample). For the remaining birds, the two tasks were different (i.e., one task was matching-to-sample; the other task was oddity-from-sample). Following acquisition, the pigeons were exposed to test trials on which either the correct or the incorrect comparison hue was replaced with one of the hues from the other task. On yellow-sample trials and on green-sample trials, the pigeons performed as if they had a common code for yellow and green. When there was one comparison available that was appropriate to the “yellow/green” code, performance remained high; but when either both comparisons or neither comparison was appropriate to the “yellow/green” code, performance dropped. The pigeons also tended to code red samples as green and to code blue samples as yellow. The results indicate that pigeons can categorically code colors under conditions that rule out a failure to discriminate among the colors.  相似文献
