This article investigates how culture shapes instruction in three early care and education programs on the Flathead Indian Reservation. Interviews with eight early childhood teachers as well as classroom observations were conducted. The investigation is framed by the following research question: How does the culture of the family and community shape curriculum? Data analysis suggested that ongoing communication with parents and community about teaching within a culturally relevant context, building a sense of belongingness and community through ritual, and respecting children, families, and community were essential to defining the Native American Indian culture within these early learning programs.  相似文献

This study deals with the question of tenure/non-tenure of the Greek school principals and its possible impact on their role in the light of the international influences. In developing our theoretical perspective, we draw on the tenure/non-tenure discourse and the centralised bureaucratic and new public management model. After examining the relevant legislation issued from 1836 up to 2015 by following the qualitative content analysis, we find out that in the 1836–1981 period, tenure had become an integral part of the centralised educational system. Since 1981, the introduction of decentralised policies along with the abolition of tenure has resulted in the renewal of the same politics. By linking in a direct way the tenure/non-tenure topic with the international policies, we support the view that in the Greek centralised educational system, school principals have limited power to bring about effective changes at schools regardless of their tenure/non-tenure status.  相似文献

In seven experiments, 2 squirrel monkeys were given choices between arrays of food that varied in the quantity offered. In Experiments 1-5, the monkeys were offered choices between quantities of the same food that varied in a 2:1 ratio. The squirrel monkeys failed to show the temporal myopia effect or a decrease in preference for the larger quantity as the absolute number of food items offered increased. Even when given choices of 8 versus 16 peanuts and 10 versus 20 peanuts, both monkeys significantly preferred the larger quantity. An examination of the monkeys' rates of consumption indicated that 20 peanuts were consumed over a 1- to 2-h period, with eating bouts separated by periods of nonconsumption. In Experiments 6A, 6B, and 7, food was either pilfered or replenished 15 min after an initial choice, so that choice of the smaller quantity led to more total food in the long run. These manipulations caused both monkeys to reduce choice of the larger quantity, relative to baseline choice. The results suggest that squirrel monkeys anticipated the future consequences of their choices.  相似文献

Current neofunctionalist views of emotion underscore the biologically adaptive and psychologically constructive contributions of emotion to organized behavior, but little is known of the development of the emotional regulatory processes by which this is fostered. Emotional regulation refers to the extrinsic and intrinsic processes responsible for monitoring, evaluating, and modifying emotional reactions. This review provides a developmental outline of emotional regulation and its relation to emotional development throughout the life-span. The biological foundations of emotional self-regulation and individual differences in regulatory tendencies are summarized. Extrinsic influences on the early regulation of a child's emotion and their long-term significance are then discussed, including a parent's direct intervention strategies, selective reinforcement and modeling processes, affective induction, and the caregiver's ecological control of opportunity for heightened emotion and its management. Intrinsic contributors to the growth of emotional self-regulatory capacities include the emergence of language and cognitive skills, the child's growing emotional and self-understanding (and cognized strategies of emotional self-control), and the emergence of a theory of personal emotion in adolescence.  相似文献

To obtain evaluative data on outcomes of the Advanced Education Institution Award scheme a study which included a survey of graduates from masters programs in Australian colleges of advanced education in the years 1980–1985 was undertaken. The survey was designed to identify graduate characteristics, to analyse award distribution across disciplines and to obtain general evaluative data on awards and masters degrees. The impact of gender in each of these analyses was to be considered. Further, details on employment and further study activities were to be documented.  相似文献

Since the establishment of the UK binary system of higher education in the mid-1960s, the Council for National Academic Awards and the public sector institutions have together evolved a distinctive system for quality maintenance.The paper has three goals: to identify the key elements in the interactions between the CNAA and its associated institutions; to sketch the shifting balance of responsibilities from the CNAA to its associated institutions; and to make some observations on course review in the public sector compared with the university sector.Central to the UK public sector is the sense, within institutions, that the responsibility for the maintenance of quality is an essentially corporate enterprise. That corporate review process has, until the present time, been conducted through the framework of a national peer review system. However, the university and the public sectors are converging in their course review processes, with individual institutions assuming greater responsibility for the quality of their courses. These changes make uncertain the continuation of the national context for course review.  相似文献
