Eight Welsh secondary schools participated in an action research project which developed approaches to teaching and assessing mathematical thinking skills involved in practical modelling situations. The development of the metacognitive and strategic skills necessary for successful modelling is discussed from a socio-constructivist perspective as a process of acculturation as well as cognitive construction. Learning to model involves socialization into the consensual realities of a wider mathematical culture and the teacher plays a pivotal role in the generation of this consensus through the legitimization of linguistically expressed subjectivities. Assessment is an integral part of this process. Participation in peer and self-assessment was found to involve the student in a recursive, self-referential learning process which supports the explicit development of metacognitive skills. 相似文献

DBA/2J mice were exposed to a distinctive floor stimulus (CS+) and ethanol (2 g/kg) in a place conditioning paradigm. A different floor stimulus (CS?) was presented with saline. Mice injected just before or 30 min before CS exposure (Groups 0, ?30) showed conditioned place preference, whereas mice injected right after exposure to the CS (Group 5) displayed place aversion (Experiment 1). None of the other groups (?120, ?60, 15, 60) showed place conditioning. Handling and saline injection given just before or after CS exposure were unable to produce place conditioning (Experiment 2). However, there was a positive relationship between ethanol concentration (10% vs. 20%) and test performance, suggesting that peritoneal irritation influences place conditioning (Experiment 3). Overall, these findings support the suggestion that intraperitoneal injection of ethanol produces an initial short-duration aversive effect that is followed by a longer lasting positive motivational effect. 相似文献

The purpose of this paper is to describe the school-based contextual constraints perceived by beginning elementary teachers as they attempted to enact their visions of effective mathematics teaching and the components of a mathematics-specific, university-based induction program designed to support elementary teachers in their teaching of mathematics. A significant number of beginning teachers in the program indicated that curriculum pacing guides and grade level teachers often discouraged their enactment of effective mathematics teaching. We describe the components of the induction program in general and then discuss the specific ways that program mentors, who were elementary teachers with expertise in mathematics teaching, supported beginning teachers in navigating the constraints identified. Data suggest that supporting teachers’ pedagogical agency to navigate local school contexts should be an additional consideration in teacher preparation and induction programs. 相似文献

History teaches the continuity of science; the developments of tomorrow have their genesis in the problems of today. Thus any attempt to look forward is well begun with an examination of unsettled questions. Since a clearer idea of where we are going smoothes the path into the unknown future, a periodic review of such questions is prudent. The present day, lying near the juncture of the centuries, is well suited for such a review. This article reports 16 unsolved problems in educational measurement and points toward what seem to be promising avenues of solution. 相似文献

Dynamation is the integrative process whereby the sum total of all learning, knowledge, experiences, and feelings are brought to bear on productive, creative action and problem solving. In this paper, we describe some of the benefits of dynamation, outline a general approach to it-including the importance of friendship (the core of the empowerment process)- and explain several key incentives that will encourage faculty, through dynamation, to engage in growth activities. Throughout the article we discuss ten techniques developers can use. Our focus is on informal facilitator-enhanced (guided) empowerment. That is, we look at growth that is likely to result when developers work with faculty with the goal of growth, change, and development.Richard L.

An interview and an intervention study are reported. Interview findings extend research on the positive relationship of parent involvement to school success. That is, although most of the low income families reported low-moderate participation, a postive relationship was found between parent involvement and school adjustment as early as kindergarten. With respect to negative valuing and barrier interpretations of low participation, the data support the latter; all but a few parents reported positive attitudes toward school involvement, while the majority indicated significant barriers. In comparing Latino and non-Latino groups, the former reported more barriers. Within the Latino group, parents whose children had made a good school adjustment indicated the most participation. Non-English proficient parents reported more barriers than those proficient in English but comparable degrees of involvement. In the intervention study, a simple strategy resulted in more treatment than control parents attending a school event. Differences in attendance were related to ethnicity and language.This work was carried out in conjunction with a dropout prevention demonstration project conducted as a collaborative effort of the School Mental Health unit (Janelle Munn, Director) and Dropout Prevention unit (Pete Martinez, Director) of the Los Angeles Unified School District and the School Mental Health Project at UCLA (Howard Adelman and Linda Taylor, Co-directors). Partial support for the project came from the U.S. Department of Education. The authors, of course, assume full responsibility for the contents, but we want to take this opportunity to acknowledge the contributions of participating schools and project staff (especially Mary Beth DiCecco and Alison McAlpine). And although she declined author credit, this work could not have been accomplished with the many contributions of Linda Taylor, the project director. We would also like to thank Regina DeWitter, Teresa Gonzales, Kathy Eides and the many other UCLA students who assisted in various phases of the research. 相似文献

Response key illuminations were followed by food delivery or shock, and keypecks were programmed to prevent the occurrence of whichever stimulus was scheduled. At high shock intensity, pigeons did not peck: at low shock intensity, pigeons pecked in about half of the trials. When different key colors signaled food and shock trials, pigeons pecked on food trials, thus preventing food delivery, but not on shock trials, thus failing to avoid shock delivery. That pecks occurred despite the fact that they avoided food but did not occur when they avoided shock is taken as evidence that the keypeck is frequently governed by biological predispositions, and not by its consequences. 相似文献

Prior research suggests that group rearing may attenuate a young bird’s tendency to approach and follow an imprinting stimulus. The present work examined the effect of group rearing on a different measure of attachment, suppression by the imprinting stimulus of distress calling induced by abrupt reductions in group size. In Experiment 1, ducklings were reared in groups of 12 or 3 over Days 1–6 posthatch, and each group received a total of 3.5 h of exposure to an imprinting stimulus. Subsequent tests revealed that, when the groups of ducklings were separated into smaller subgroups: (1) the fewer the ducklings in a subgroup, the more distress calls emitted; (2) a given number of birds separated from a larger group emitted more distress calls than an equal number from a smaller group; and (3) regardless of the subgroup size, fewer distress calls occurred when the imprinting stimulus was present than when it was absent. A second experiment revealed that when a group of 12 birds was first confronted with an imprinting stimulus on Day 6 posthatch, they reacted with an increase in distress calling and corner huddling (an aversive reaction). After several hours of exposure to the stimulus, however, its presence exerted a powerful suppressive effect on distress calling. It is concluded that the social bonds between the members of a brood do not preclude the formation of a social attachment to an imprinting stimulus subsequently encountered. 相似文献

Maternal Representations of Attachment during Pregnancy Predict the Organization of Infant-Mother Attachment at One Year of Age 总被引:4,自引:0,他引:4
While strong retrospective and concurrent associations between maternal and infant patterns of attachment have been noted, this is one of the first reports of a prospective investigation of such associations. The Adult Attachment Interview was administered to 100 mothers expecting their first child, and, at 1-year follow-up, 96 of these were seen with their infants at 12 months in the Strange Situation. Maternal representations of attachment (autonomous vs. dismissing or preoccupied) predicted subsequent infant-mother attachment patterns (secure vs. insecure) 75% of the time. These observed concordances, as well as the discordances, are discussed in terms of the uniquely powerful contribution the Adult Attachment Interview makes to the study of representational and intergenerational influences on the development of the infant-mother attachment. 相似文献
