The lack of coherence between early childhood education settings and primary school classrooms provides a challenge to the creation of a seamless educational experience in the period from birth to age eight. This paper examines the nature of technological activities in Kindergartens and New Entrant/Year One classes in New Zealand. It highlights commonalities between the two and discusses the potential for technology education to provide a bridge for children to ease their passage into the formal school setting and to provide a coherent educational experience.  相似文献

Using data from a sample of 10 colleges at which most students had taken both SAT I: Reasoning tests and SAT II: Subject tests, we simulated the effects of making selection decisions using SAT II scores in place of SAT I scores. Specifically, we treated the students in each college as forming the applicant pool for a more select college, and then selected the top two thirds (and top one third) of the students using high school grade point average combined with either SAT I scores or the average of SAT II scores. Success rates, in terms of first-year grade point averages, were virtually identical for students selected by the different models. The percentage of African American, Asian American, and White students selected varied only slightly across models. Appreciably more Mexican American and Other Latino students were selected with the model that used SAT II scores in place of SAT I scores because these students submitted subject test scores for the Spanish test on which they had high scores.  相似文献

ABSTRACT

Along with the dramatic expansion of private tutoring around the world, a significant body of literature has been produced to understand this phenomenon. While many studies consider the issue of geographic location, the spatial dimension tends not to be a central focus of private tutoring studies. In contrast, the present essay applies mobility theory to research from Cambodia, where private tutoring is essential to student success. It does so in order to place private tutoring provision into a broader perspective that includes but moves beyond the economic dimensions of supply and demand and the sociological dimensions of economic, cultural, and social capital to include consideration of how private tutoring provision is constrained by a multidimensional spatial field of possibilities and how private tutoring participation is enabled by one’s position and abilities in relation to that field. The paper argues for increased attention to ‘spatial capital’ in studies of private tutoring and education generally.  相似文献

In this article the authors examine elaboration theory (ET), a model for sequencing and organizing courses which was developed by Charles Reigeluth and associates in the late 1970s. The purpose of the article is to offer a critique of ET based on recent cognitive research and to offer suggestions for updating the model to reflect new knowledge.Commentary by Charles Reigeluth follows this article.  相似文献

This paper looks at the changing patterns ofresourcing (financing) education in thetwenty-first century. It identifies five trendsthat are altering the resourcing and provisionof education through their impact on theorganization of education systems. As aconsequence of these trends, it puts forwardthe view that the role of government ischanging from direct provider of education toone of regulator of the education industry.  相似文献

Parental involvement and participation, partnership with parents, and community‐focused development are important features of government initiatives such as the Sure Start project for children under four years of age and their families. A common feature of the rhetoric is ‘empowerment’ as a means of achieving this. This article describes the activity and development of the Parents Committee in one Sure Start programme and uses this to tease out different dimensions of empowerment. In particular, it highlights issues regarding developing empowerment and the dynamic tension between the growth of personal power and the changing symmetry of power relationships. A tentative model of the trajectory of developing empowerment is presented. This may raise challenges for professionals seeking to fulfill their professional role in a complex context and questions as to whether, or how, it might be possible to better prepare professionals for this dimension of their work.  相似文献

This paper describes a novel instructional model for sequencing, syntheizing, and summarizing subject-matter content. The importance of such models is discussed, along with the need for a significant change in the role of subject-matter structure in instruction. A zoom-lens analogy is presented to facilitate an understanding of the elaboration model of instruction. Some basic concepts and principles upon which the model is based are described. The basic unvarying components of the elaboration model are described. And finally, some variations in the model for different kinds of goals are described. The elaboration model follows a general-to-detailed pattern of sequencing, as opposed to the hierarchically based sequences derived from Gagné-type task analyses.Many of the ideas described in this paper were developed under two projeets, one funded by Brigham Young University in Provo, Utah, and the other by the Navy Personnel Research and Development Center in San Diego, California; however, the ideas expressed do not necessarily constitute the opinions of the funding institutions.  相似文献

Drawing on results from psychology and from cultural and linguistic studies, we argue for an increased focus on developing quantity sense in school mathematics. We explore the notion of “feeling number”, a phrase that we offer in a twofold sense—resisting tendencies to feel numb-er (more numb) by developing a feeling for numbers and the quantities they represent. First, we distinguish between quantity sense and the relatively vague notion of number sense. Second, we consider the human capacity for quantity sense and place that in the context of related cultural issues, including verbal and symbolic representations of number. Third and more pragmatically, we offer teaching strategies that seem helpful in the development of quantity sense coupled with number sense. Finally, we argue that there is a moral imperative to connect number sense with such a quantity sense that allows students to feel the weight of numbers. It is important that learners develop a feeling for number, which includes a sense of what numbers are and what they can do.  相似文献
