One of the most controversial issues in special education over the last 40 years has been the extent to which students with learning disabilities (LD) should be educated in general education classrooms. Recent mandates in federal law requiring that all students with disabilities have access to the general education curriculum and make adequate yearly progress relative to this content have intensified this debate. In this article, a brief summary of research regarding the nature of instruction that produces significantly improved educational outcomes for students with LD is provided. This is followed by a review of research related to the delivery of this high‐quality instruction in inclusive, general education classrooms and in resource settings. We conclude that this research provides the foundation for reconsidering full inclusion and how services are delivered for elementary students with LD. 相似文献

ABSTRACT Using a methodology inspired by structural narratology and by James Hamilton’s [2016. Democracy’s Detectives: The Economics of Investigative Journalism. Cambridge: Harvard] economic analysis of investigative journalism, this paper identifies a set of 14 recurring structural and formal elements (plot events, character types and functions, visual iconography) that constitute a fable about investigative journalism. The fable structure is applied to analyze six diverse films about investigative journalism produced in the US in the last 40 years. The films include two instantiations of successful investigative journalism (All the President’s Men, Spotlight), two cases where conflict between journalists and corporate managers diminished the impact of the investigation (Good Night and Good Luck, The Insider), and two instances of a counter-fable of failed investigative journalism (Truth, Kill the Messenger). The paper argues that the films’ representation of investigative journalism influences public perceptions of investigative journalism. It also speculates about the factors that will influence investigative journalism and its representations in the current political context in the US. 相似文献

Chi (1992, 1993) Chi et al. (1994) suggests that many of the difficulties encountered by students in learning Physics concepts arise because they attribute the ontology of material substances to these concepts. These concepts are actually a special type of process - 'Constraint-Based Interactions' (CBI). Slotta and Chi (1996) reported on a study where a group of students explicitly trained in the CBI ontology showed significant gains over a control group in problem solving performance in eight simple electric circuit problems. This paper reports on a series of four studies which explore the usefulness of the ontological categorization framework in investigating students' alternative conceptions of electric circuits and in developing a teaching strategy for promoting conceptual change in the learning of basic electric circuitry concepts. 相似文献

Abstract In this study we describe and examine the effectiveness of an instructional program designed to teach learning disabled adolescents to make better personal decisions. We presented problems in short narratives based on the types of problems these students must solve in their own lives. The program, conducted as part of the students' regular resource room curriculum, incorporated schema‐general questions for problem solving coupled with practice in generating problem‐specific questions to reach an appropriate decision. Participants were 70 resource room students in two large, urban high schools. We employed a pretest‐posttest comparison group design. On the posttest, instructed students performed significantly better on (1) identifying a general schema for making a personal decision and (2) applying the schema to reach appropriate decisions concerning novel problem narratives. The results support the view that application of a general schema to specific problems can be an effective instructional method to improve critical thinking and decision making. 相似文献

Troubleshooting electronic resource linking issues can seem to be an insurmountable task—so many resources, so little time. Using interlibrary loan (ILL) data on requests for materials available online, the electronic resources staff at the Samford University Library detected problems with the implementation of their new link resolver. This data also provided a window into some systemic issues within the metadata of certain sources and the link resolver knowledgebase. In addition to helping us improve linking for our users, the establishment of a workflow for communicating cancelled ILL transaction data on an ongoing basis has also improved the communication between electronic resources staff and the ILL department regarding the overall linking process. 相似文献

This article is a response to the excellent “Using Mobile Technology to Observe Student Study Behaviors and Track Library Space Usage” by Susan Thompson. Thompson reviews the literature regarding user counts on mobile devices and describes the California State University San Marcos (CSUSM) Library's evaluation of SUMA, Counter+, and CloudOn. After trialing these mobile technologies, CSUSM selected CloudOn. At New York University Abu Dhabi, we use Google Forms to conduct user counts on an iPad and Google Sheets to evaluate these data. We find that Google Forms are easy to set up, modify as necessary, and present the data in easy-to-manipulate spreadsheets. 相似文献

We contrast the current science education reform effort with the reforms of the 1960s and suggest how the current effort could be enhanced. We identify insights from recent research that we believe can inform the reform process, in particular, to reach all science students and also impart a cohesive view of science. We propose an alternative models view of scientific explanation and show how this view would contribute to reforms of (1) course goals, (2) social aspects of science learning, (3) instructional practices, and (4) roles for technology.This paper summarizes discussions and debates that the authors have had over the last few years. The dialogue stems, in part, from our joint participation in the American Educational Research Association Special Interest Group on Education in Science and Technology (AERA SIG:EST) leadership. This paper communicates the spirit of our thinking and does not necessarily reflect the view of SIG:EST, or any other organization.We gratefully acknowledge the support of National Science Foundation Grant MDR-9253462 in work related to this paper.
