Students with learning disabilities (LD) consistently struggle with word problem solving in mathematics classes. This difficulty has made curricular, state, and national tests particularly stressful, as word problem solving has become a predominant feature of such student performance assessments. Research suggests that students with LD perform poorly on word problem‐solving items due primarily to deficits in problem representation. Therefore, it is imperative that teachers provide these students with supplemental problem‐solving instruction that specifically targets the development of representational strategies. This article describes how one representational strategy, using number lines, can be used to model word problems as part of a comprehensive problem‐solving intervention to improve the conceptual understanding of math word problems and, subsequently, the problem‐solving performance of students with LD. 相似文献

The purpose of this article is to offer teacher training and professional development recommendations in mathematics based on the findings of a federally funded 3‐year intervention study that improved the problem solving of middle school students with a focus on students with learning disabilities. Over the 3‐year project, 29 seventh and eighth grade teachers implemented a problem‐solving intervention based on cognitive strategy instruction. Though the intervention was successful in improving students’ problem‐solving performance, several issues related to teaching effectiveness and teacher training came to light. The article will: (1) describe the intervention and its implementation, (2) present the findings of the study, and (3) discuss the issues of effectiveness and possible solutions via teacher education and professional development. 相似文献

ABSTRACT Meta-analytic evidence supports that exercise has benefits for short-term memory (STM) and long-term memory (LTM). However, only three studies with children have tested the differential effects of exercise on STM and LTM. The purpose of this study was to examine the effects of an aerobic fitness test on STM and LTM and to consider the moderating effects of grade level. Children (7–13 years of age) were randomly assigned to either perform an aerobic fitness test before (exercise prior) or after (exercise post) performing the Rey Auditory Verbal Learning Test (RAVLT) to assess memory. Memory was tested again after approximately 24 hours. There were significant differences in memory performance as a function of grade with 4th and 6th graders consistently outperforming 2nd graders. For learning, Day 1 Retention, 24-hr recall, and Day 2 Retention, the exercise prior group performed better than the exercise post group. It is concluded that an aerobic fitness test performed prior to a declarative memory test benefits LTM as compared to when the aerobic fitness test is performed after the memory test. 相似文献

Students with LD who struggle with reading comprehension can benefit from instruction on how to read strategically. One strategy that has been demonstrated to increase reading comprehension is self‐questioning. In this study, two fifth graders with LD were taught to self‐generate questions using a prompt fading procedure. The participants were provided with expository reading passages with embedded questions. As each participant demonstrated proficiency with answering the embedded questions correctly, the embedded questions were systematically faded and replaced with a prompt for the students to generate their own questions. A multiple baseline across participants design demonstrated that the self‐questioning intervention resulted in improvements in reading comprehension for both students. Additionally, the students demonstrated evidence of maintenance and generalization of reading comprehension outcomes. 相似文献

Solving word problems is a common area of struggle for students with learning disabilities (LD). In order for instruction to be effective, we first need to have a clear understanding of the specific errors exhibited by students with LD during problem solving. Error analysis has proven to be an effective tool in other areas of math but has had little application to errors in word problems. Using an error analysis approach, this study aimed to investigate in depth the various types and frequency of errors made by students with LD and their AA peers during math problem solving. The resulting similarities and differences between the two groups of students are discussed with insight into underlying cognitive processes, and implications for future research. 相似文献

ABSTRACTIn states with limited road accessibility, rural students can feel isolated from library services. This article explores the creation, implementation, and results of an on-going longitudinal study assessing the library service needs of rural students in eLearning courses. To align with current practices in online pedagogies, including the Association of College and Research Libraries' Standards for Distance Learning Library Services and recent revisions to the Framework for Information Literacy for Higher Education, this survey has been designed to help the library identify and improve services to enhance rural student success. 相似文献

Failure Modes and Effects Analysis (FMEA) is a proactive assessment tool originally created for quality assurance in manufacturing industries. FMEA involves the assignment of rankings for frequency, severity, and detection of errors within a process. Catalogers at ProQuest undertook an innovative project to use FMEA to evaluate MARC record production. This article provides an overview of FMEA for process evaluation and summarizes an application for cataloging. It considers the tool's value for error-proofing in MARC record creation and how FMEA might be applied more effectively in a variable environment. 相似文献

This article describes the planning and development of a 3D printing makerspace at an academic health sciences library. At the start of 2015, a new library Technology Team was formed consisting of a team leader, an emerging technologies librarian, and a library systems analyst. One of the critical steps in the development of the proposal and with the planning of this project was collaborating and partnering with different departments and units outside the library. These connections helped shape the design of the makerspace. 相似文献

ABSTRACTThe University of Northern Colorado (UNC) Libraries have experienced a surge in streaming video requests in the past few years. Like others, UNC’s Technical Services department has found new ways to manage procedures and workflows associated with this format. This session covered the experiences and strategies of the presenters for handling streaming video databases, licensed content ripped from DVD, firm orders, and multiyear streaming licenses. 相似文献
