When the history of 20th century American Jewry will be written, the central agency for Jewish education will play a prominent role in the story of the local Jewish community. In the first place, the bureau of Jewish education is one of a handful of Jewish organizations spanning the entire century. Moreover, with few exceptions, its constituents represent the total spectrum of the local Jewish population.  相似文献

An animal’s appetitive behavior is not a fixed response to current stimulation but can be affected by the anticipation of future events. For example, rats regularly given access to a moderately valued solution followed by a higher value solution (e.g., 4 % sucrose → 32 % sucrose) consume less of the initial solution than in control conditions where the initial solution is not followed by a higher value solution (e.g., 4 % sucrose → 4 % sucrose). Previous analyses have suggested that this negative anticipatory contrast effect does not depend on the “expectation” of a valuable stimulus producing a functional devaluation of a currently available stimulus of lesser value. In a within-subjects anticipatory contrast procedure, this study revealed that both consumption and the mean size of licking clusters were smaller for a 4 % sucrose solution on days when it preceded 32 % sucrose than on days when 4 % preceded 4 %. Since lick cluster size typically bears a positive monotonic relationship with the concentration of palatable solutions, this reduction is indicative of a decrease in the palatability/hedonic value of the solution subject to contrast. As such, we provide direct evidence that negative anticipatory contrast does produce a functional devaluation of the solution, thus challenging prevailing theoretical assumptions.  相似文献

Abstract

Adults constitute a continually increasing proportion of students at two-year colleges. While adult students presumably have special needs, little is known about them. This study focused on the characteristics and needs of 17,137 students enrolled in 100 randomly selected two-year colleges across the country, separately for different age levels. Using a wide variety of variables collected at entrance, after one term, at graduation, and three years after graduation, differences by sex among the following four age groups were ascertained: age 19 or younger, 20–24, 25–39, and 40 or older. Major trends with age, differences among age groups, and interactions between age and sex were found for a number of variables: abilities, grades, attrition, self-perceptions, aspirations and goals, competencies, job values and preferences, satisfaction with and rating of various aspects of the college, expressed needs for help, extracurricular participation, outside work during school, postgraduate jobs obtained and how obtained, job satisfaction, percent going to and graduating from four-year programs, and preference for entering a two-year program if they had to do it all over again. Adult students do have many special needs that vary with age level. We think a repeat of the study but comparing across other groupings of adults would be desirable, even though extreme diversity also exists within such groups. Another consideration is that many new kinds of adult students will in the future be entering postsecondary education in large numbers.  相似文献

Research on job satisfaction among community college faculty has been largely atheoretical. The present study examined the contribution of four sets of factors to explaining faculty job satisfaction in the community college. According to Kalleberg's (1977) theory of job satisfaction, employee's affective reactions to their jobs are largely determined by ascribed social statuses, achieved social statuses, job values, and job rewards. A random sample was drawn of 371 full‐time faculty from a multi‐campus community college district located in a metropolitan area in the Southwest. Nonresponses and partial responses resulted in an effective sample size of 261. A correlation analysis revealed that institutional age and physical safety job value were significantly, inversely related to job satisfaction and that all job rewards were significantly, positively related to job satisfaction. A simultaneous multiple regression analysis indicated that institutional age was a significant, inverse predictor of job satisfaction and that chronological age, and the good supervision and work itself job rewards were significant, positive predictors of job satisfaction. Of the variation in job satisfaction scores accounted for by all predictors, approximately 5% may be attributed to ascribed and achieved social statuses and to job values, and 48% to job rewards. For faculty in the district we surveyed, the keys to promoting job satisfaction would be to enhance the satisfying aspects of the work itself and good supervision. Programs which afford faculty who are less than satisfied with their jobs opportunities to be “origins” rather than “pawns” may be beneficial.  相似文献

Instructors in community and junior colleges within the Southern Association of Colleges and Schools’ accrediting region were the focus of this study to determine characteristics and activities of those teaching history. A questionnaire was mailed to each history instructor in 88 of the 285 institutions in the region. A total of 230 instructors responded. After data were compiled and analyzed, it was determined that the typical history instructor in the region is a married, middle‐aged male who is Southern born and bred, and holds at least a master's degree in history. He has been in his present position for at least 10 years, coming to the present position from the high school ranks. The lecture method is used in teaching the 13‐to 15‐credit‐hour average load. Teaching is the primary activity of history instructors, with research and service not a part of usual expectations.  相似文献

This study focuses on how two teachers working in reduced-size secondary classes of the same grade adapted their pedagogy as a result of a brokered dialogue between myself as researcher and 43 grade 10 students from the teachers’ classes. Research was carried out over the course of one academic year. First, students’ perspectives on studying in a reduced-size class were elicited before they were invited to suggest ways of improving the teaching and learning. These interviews were transcribed and given to the teachers of these classes. Next, these teachers were interviewed to gauge their opinions on what the students had reported in the earlier interviews. At a later stage, their teaching was observed to determine whether, and to what extent, the two teachers had attempted to incorporate changes based on the feedback from pupils. The study showed that the pupil voice is a very powerful and constructive trigger for enacting teachers’ pedagogical change and developing our understanding of students’ learning processes. Findings demonstrate that teachers responded positively to their students’ perspectives despite initial apprehensions. Implications for professional development and good practices in reduced-size classes are also presented.  相似文献

文章以健康传播研究为范本,建构了一个具有普遍示范意义的应用传播学的研究大纲和分析模式.健康传播的研究一般沿着两个维度展开:一是传播的效应维度,分为健康信息的触达与认知、健康观念的形成与演化、健康行为的启动与培育三个层次;二是传播的社会维度,分为微观个体性因素对健康传播与信息加工的影响、中观群体性因素对健康传播与信息加工的影响、宏观社会性因素对健康传播与信息加工的影响三个方面.文章基于发轫于美国的“健康信息全国趋势调查”,并结合我们在中国HINTS调查所获得的研究经验,较为详尽地探讨了如何对调查数据进行深度价值挖掘,以及其所依照的十个相关理论模型的框架和范式.  相似文献

Despite the importance of early writing development to children’s school success, research documents that early childhood teachers spend little time actively supporting children’s writing development in preschool classrooms. This article provides a framework for integrating writing experiences across the early childhood curriculum. Practical examples are given regarding how writing opportunities can be incorporated into existing activities and play settings. The metaphor of backgrounding and foregrounding writing experiences is used to illustrate ways that teachers can set writing rich environments and activities in a manner that makes it easier for teachers to bring these experiences into everyday learning opportunities. Attention is given to how teachers can bring writing to the foreground of the curriculum by drawing attention to writing materials, making natural connections with children’s interest and play, and scaffolding children’s early writing attempts and experiences.  相似文献
