Policy responses to disparities in education have proven to be largely inadequate in reducing persistent differences in academic outcomes, commonly referred to as the achievement gap. In this article, we identify some of the ways in which the fragmented nature of public policy generally, and education policy specifically, has contributed to the problem. We draw upon research from a variety of disciplines to argue that the most effective way to address the broad array of social and economic conditions impacting low-income children and their families is through the adoption of an ecological approach, similar to those used in public health. In order for education policies to promote equity in academic outcomes, they must explicitly address the ways in which race, class, language, and culture, as well as implementation processes, reproduce and reinforce disparities in academic achievement. We propose a new, comprehensive framework for equity-based education policy that makes it possible to respond to the social and economic factors that impact, and often undermine, efforts to improve academic outcomes. An analysis of California’s Local Control Funding Formula (LCFF) and interviews with senior county leaders allows the authors to draw connections to the new policy framework, generating recommendations for strengthening education policies like LCFF. 相似文献

Reform efforts in science education emphasize the importance of supporting students' construction of knowledge through inquiry. Project‐based science (PBS) is an ambitious approach to science instruction that addresses concerns of reformers. A sample of 142 10th‐ and 11th‐grade students enrolled in a PBS program completed the 12th‐grade 1996 National Assessment of Educational Progress (NAEP) science test. Compared with subgroups identified by NAEP that most closely matched our student sample, White and middle class, PBS students outscored the national sample on 44% of NAEP test items. This study shows that students participating in a PBS curriculum were prepared for this type of testing. Educators should be encouraged to use inquiry‐based approaches such as PBS to implement reform in their schools. © 2002 Wiley Periodicals, Inc. J Res Sci Teach 39: 410–422, 2002 相似文献

The purpose of this paper is to delineate several problems which arise when criterion-referenced test results are used to evaluate the effects of a specific educational treatment. Specifically, the paper deals with: (1) alternative methods of aggregating individual student and group data on objectives, (2) the sensitivity of the instrument to program outcomes, and (3) the comparisons of criterion-referenced test data and standardized (norm-referenced) achievement test data. 相似文献

Many students have difficulty learning symbolic and molecular representations of chemistry. This study investigated how students developed an understanding of chemical representations with the aid of a computer‐based visualizing tool, eChem, that allowed them to build molecular models and view multiple representations simultaneously. Multiple sources of data were collected with the participation of 71 eleventh graders at a small public high school over a 6‐week period. The results of pre‐ and posttests showed that students' understanding of chemical representations improved substantially (p < .001, effect size = 2.68‐. The analysis of video recordings revealed that several features in eChem helped students construct models and translate representations. Students who were highly engaged in discussions while using eChem made referential linkages between visual and conceptual aspects of representations. This in turn may have deepened their understanding of chemical representations and concepts. The findings also suggest that computerized models can serve as a vehicle for students to generate mental images. Finally, students demonstrated their preferences of certain types of representations and did not use all types of three‐dimensional models interchangeably. © 2001 John Wiley & Sons, Inc.

Increasing demands for information about higher education lead the authors to reconsider the issue of privacy from an ethical point of view. Both individuals and institutions, it is argued, should be treated alike as subjects. Threats to privacy include (1) collection of information without consent, (2) unwarranted interpretation of information, and (3) dissemination of information beyond subjects' intent. It is contended that the burdens of justification, gaining cooperation and trust of subjects, and bearing responsibility for protection of subjects' privacy lie with the researcher. Failure on his part to assume these burdens justifies refusal of cooperation on the part of subjects. 相似文献
