Two experiments indicated that two approaches to serial learning are too extreme—the classical view that it consists only of interitem associations and various recent views that it involves no interitem associations. The novel assumption introduced here was that phrasing cues, normally conceptualized as merely segregating long series into smaller units or chunks, may also enter into associations with items, thereby reducing interitem interference and facilitating serial learning. It was found that one item could become a signal for another item, an interitem association, or be overshadowed by a phrasing cue, such as a brightness and temporal cue, also signaling that item. The items were .045-g pellets. Rats traversed a runway for items arranged in ordered series, 14-7-3-1-0 pellets (Experiment 1) or 10-2-0-10 (Experiment 2). Complete tracking of, for example, the 10-2-0-10 series would consist of fastest running to 10 pellets and slowest running to 0 pellets. In both investigations, the interitem association overshadowed was that between 0 pellets and the subsequent rewarded item, 0 → 14 (Experiment 1) or 0 → 10 (Experiment 2). Either repetitions of the 14-7-3-1-0 subpattern (Experiment 1) or merely the terminal 10-pellet item (Experiment 2) were phrased, both methods producing identical results. Overshadowing the 0-pellet item produced superior serial learning, more rapid extinction, and, in Experiment 1, considerable elevation of responding when the brightness phrasing cue was introduced in extinction, an effect said to be conceptually identical to spontaneous recovery and one demonstrating directly that phrasing cues are in reality overshadowing cues. It was suggested that many effects attributed to forgetting may be due to unrecognized overshadowing of memory cues by phrasing cues, giving rise to exaggerated estimates of forgetting.  相似文献

This article examines and critiques the leadership capacity of department leaders in a high school and attempts to gain a deeper understanding of how department leaders perceive their role as teacher leaders, making a distinction between what an individual department leader does in his or her position and teacher leadership as a form of continuous learning and innovation through collaboration. How do department leaders practice leadership to improve student learning? The author provides an investigation and analysis of the current level of leadership capacity exhibited by department leaders in a high school. A close look at the role and function of department leaders in this high school reveals an absence of the teacher leadership necessary to promote the broad-based leadership capacity that results in improved student achievement.  相似文献

Eating is broadly conceptualized as food choice. Food choice is a complex activity with many dimensions. Food choice is multifaceted as it involves whether, where, when, how long, how, why, with whom, for whom, and under what conditions eating occurs. Food choice is contextual as it is situated within specific conditions and settings involving both individuals and institutions. Food choice is dynamic as it unfolds and is embedded in eating episodes over lifetimes within historical eras. Food choice is multilevel as physical, biological, psychological, and sociocultural factors operate simultaneously and interact. Food choice is integrated as people coordinate many considerations to construct specific eating activities. Food choice is diverse in its broad scope of distinct and unique eating activities. Food choice can be examined using both multi‐perspective and multi‐purpose approaches, and it may not be possible to integrate different perspectives into a unified approach to understanding and changing food choice.  相似文献

This piece responds to the content of each of the articles in this issue and raises questions in response to some explicit and implicit themes including particularly the way that differently positioned rural youth are “oriented” in the course of their educational experience. These articles are read as accounts of people in place that confound and confront simplistic deficit assessments of educational paths, aspirations, relationships, and purposes in rural space. I suggest that this issue illustrates how rural education scholarship inevitably returns to the particular and to the material, challenging the hegemony of the placeless and abstracted neoliberal vision of education's aims in late modernity. The broad argument is that educational struggles and orientations in rural schools should be understood in relation to the crucial global challenges of sustainability and survival.  相似文献

1. This article contains the specific yearly requirements of the National Curriculum for the Six-Year Elementary School Language Educational Program. It is the sequence for the edited education materials and for the implementation of instruction. It is based upon the principles of: from shallow to deep, near to far, simple to complex, perceptual to conceptual. It provides the specific educational standards by year for "character, word, sentence, article; listen, speak, read, write" and other areas. These different areas of educational standards are inextricably interrelated.  相似文献

Simple, reliable and sensitive analytical methods to determine anticariogenic agents, preservatives, and artificial sweeteners contained in commercial gargles are necessary for evaluating their effectiveness, safety, and quality. An ion chromatography (IC) method has been described to analyze simultaneously eight anions including fluoride, chloride, sulfate, phosphate,monofluorophosphate, glycerophosphate (anticariogenic agents), sorbate (a preservative), and saccharin (an artificial sweetener)in gargles. In this IC system, we applied a mobile phased gradient elution with KOH, separation by IonPac AS18 columns, and suppressed conductivity detection. Optimized analytical conditions were further evaluated for accuracy. The relative standard deviations (RSDs) of the inter-day's retention time and peak area of all species were less than 0.938% and 8.731%, respectively,while RSDs of 5-day retention time and peak area were less than 1.265% and 8.934%, respectively. The correlation coefficients for targeted analytes ranged from 0.999 7 to 1.000 0. The spiked recoveries for the anions were 90%~102.5%. We concluded that the method can be applied for comprehensive evaluation of commercial gargles.  相似文献

Science achievement and attitudes were assessed for a series of students in Grades 3–12 representing the four major ethnic groups in Hawai'i (USA). It was found that more differences were accounted for by ethnicity and even grade than by gender; in addition, there was little interaction between ethnicity and gender. With respect to ethnicity, Caucasian and Japanese-American students outscored Hawaiians and Filipino Americans at all grade levels. Caucasians also expressed the most positive attitudes toward science and Japanese expressed the most positive perceptions of scientists; Hawaiians generally expressed the least positive perceptions. Younger students generally expressed more positive attitudes toward science but less positive perceptions of scientists compared to older students. Caucasians expressed the most positive perceptions of their own science ability and achievement. With respect to gender, there were no consistent differences in science achievement and very few in science attitudes and perceptions. The major differences were that males reported more experiences with physical science activities and also expressed a more male-stereotyped view of science than females, with some variation by ethnicity and grade. There were differences in enrollment in advanced science and mathematics classes in that females were more likely than males to enroll in many, but for both genders the major reason was college admission: Japanese students were most likely and Hawaiians least likely to indicate science interest as a reason. Findings are discussed within the context of cultural ecology and feminist social theory. © 1996 John Wiley & Sons, Inc.  相似文献

ABSTRACT— Circadian rhythms, in particular the sleep–wake cycle, modulate most, if not all, aspects of physiology and behavior. Their impact on education has recently begun to be understood, including a clear positive relationship between sleep and learning. In fact, sleep deprivation, common to adolescents throughout the world, has a deep effect on academic performance, and this fact is often increased by inadequate school schedules. This special issue of Mind, Brain, and Education deals with the relation between biological rhythms and learning, as discussed in an International Mind, Brain, and Education Society meeting that took place in Erice, Italy in May 2007. The articles (with contributors from Brazil, Croatia, Sweden, Spain, United Kingdom, United States, and Argentina) cover several aspects of this fundamental link between timing and education and suggest strategies to optimize school and sleep schedules for a better quality of life and improved academic performance of students.  相似文献

The hyperbolic-decay model is a mathematical expression of the relation between delay and reinforcer value. The model has been used to predict choices in discrete-trial experiments on delay-amount tradeoffs, on preference for variable over fixed delays, and on probabilistic reinforcement. Experiments manipulating the presence or absence of conditioned reinforcers on trials that end without primary reinforcement have provided evidence that the hyperbolic-decay model actually predicts the strength of conditioned reinforcers rather than the strength of delayed primary reinforcers. The model states that the strength of a conditioned reinforcer is inversely related to the time spent in its presence before a primary reinforcer is delivered. A possible way to integrate the model with Grace’s (1994) contextual-choice model for concurrent-chain schedules is presented. Also discussed are unresolved difficulties in determining exactly when a stimulus will or will not serve as a conditioned reinforcer.  相似文献

ABSTRACT

This article proposes that Catherine Elgin and Nelson Goodman’s work on exemplification is relevant for discussions within moral philosophy and moral education. Generalizing Elgin and Goodman’s account of exemplification to also cover ethics, the article develops a two-factor account of moral exemplarity. According to this account, instantiation and expressivity are individually necessary and jointly sufficient conditions for someone or something to function as a moral exemplar. Applying this two-factor account of exemplarity to discussions within the philosophy of moral education the article then argues that it is the expressive aspect of moral exemplars, which explains and justifies the educational significance of such exemplars. The article concludes by discussing the similarities and differences between the expressivity account and the transparency criterion formulated by Michel Croce and Maria Silvia Vaccarezza in a recent paper.  相似文献

Abstract

The Science and Engineering Foundation Programme at Loughborough University has been running since October 1991. It has a heterogeneous intake of approximately 100 students. The author is responsible for the physics input to the Programme. This provides 25% of the Programme for almost all the students. The varied educational profile of students entering this course necessitated a radical rethink of course design for the author. She chose to concentrate initially on one aspect of her teaching — that of running tutorials — and used Mackinnon's cycle of reflection to assist in these deliberations. The result was both an improvement in the learning environment for students and a growing awareness on her part of the necessity to persist with the reflective process to ensure continued enhancement of the student learning experience. Reflection was found to be an important technique with wide application both within and outside the educational sphere.  相似文献

ABSTRACT

The instructional leadership role of the principal has received much attention in the literature. The present study draws upon emerging research and explores the basis for predicting school academic achievement from the instructional leadership behavior of principals. A model of instructional leadership was examined to determine its predictive power in correctly identifying high‐ and low‐achieving elementary and high schools in two distinct cultural contexts. A total of 265 teachers and principals from California and the Marshall Islands participated in the study. The results indicate that school academic achievement can be predicted from a knowledge of principal instructional leadership behaviors. The theoretical and practical implications of the results are discussed.  相似文献

The subject of school and society is more comprehensive in the yearbook for 1979 than it usually is. Several factors are responsible for this: in the first place the reportage covers two years and in the second place it has been extended further, namely to March 30, so that it could cover both the school year and the parliamentary year, allowing us to report on legislative initiatives and the school debate around them in a mutually coherent way. Finally, material concerning the school has been much more abundant in the daily press now than earlier. This is both because some particularly important subjects have been debated, such as morning prayer, the Tvind school, and the U-90, and also because material concerning the school has been dealt with much more by the mass media than previously, and various events have been covered more comprehensively and in more newspapers than before.  相似文献

Abstract

The present research was conducted to explore the relationship between bullying and parenting styles in an incidental sample of 626 high school students (49.7% girls). The information was collected by means of a self-report questionnaire that contained two instruments: European Bullying Intervention Project Questionnaire and Scale for the assessment of the parenting styles of mothers and fathers of adolescents. The results show statistically significant differences in the perception of parenting styles between the students involved and not involved in bullying and between the different kinds of involvement. Different dimensions of parenting styles are also categorized as being risk or protective factors of bullying involvement. In agreement with the previous research, we have specifically found that perception of parenting styles (especially behavioural control and affection and communication) is significantly related to bullying involvement, especially regarding the role of aggressor.  相似文献

Widespread interest in the concept of inclusion for young children with disabilities has been focused primarily on inclusion in day care and classroom settings. While these contexts provide important opportunities for inclusion, many other community contexts are also important. Interviews with families of children with and without disabilities were analyzed to identify factors that facilitated or served as barriers to children's inclusion in community settings. These factors are described in terms of their application to children with and without disabilities and the extent to which they were reflected in communities of varying size and various income levels. Results are interpreted with respect to an ecological model and are discussed in terms of their implications for intervention.  相似文献
