Test–retest reliability of the 30–15 Intermittent Fitness Test: A systematic review     

Jozo Grgic  Bruno Lazinica  Zeljko Pedisic 《运动与健康科学(英文)》2021,10(4):413

PurposeThis review aimed to synthesize previous findings on the test–retest reliability of the 30–15 Intermittent Fitness Test (IFT).MethodsThe literature searches were performed in 8 databases. Studies that examined the test–retest reliability of the 30–15 IFT and presented the intraclass correlation coefficient (ICC) and/or the coefficient of variation (CV) for maximal velocity and/or peak heart rate were included. The consensus-based standards for the selection of health measurement instruments (COSMIN) checklist was used for the assessment of the methodological quality of the included studies.ResultsSeven studies, with a total of 10 study groups, explored reliability of maximal velocity assessed by the 30–15 IFT. ICCs ranged from 0.80 to 0.99, where 70% of ICCs were ≥0.90. CVs for maximal velocity ranged from 1.5% to 6.0%. Six studies, with a total of 7 study groups, explored reliability of peak heart rate as assessed by the 30–15 IFT. ICCs ranged from 0.90 to 0.97 (i.e., all ICCs were ≥0.90). CVs ranged from 0.6% to 4.8%. All included studies were of excellent methodological quality.ConclusionFrom the results of this systematic review, it can be concluded that the 30–15 IFT has excellent test–retest reliability for both maximal velocity and peak heart rate. The test may, therefore, be used as a reliable measure of fitness in research and sports practice.  相似文献   

泛在技术环境下教学体验与教师角色     

张金磊  张宝辉  刘永贵 《现代远程教育研究》2013,(6):98-104,111

随着3G技术、人工智能和云计算等关键技术的快速发展,泛在技术开始出现在多种教育场景中。然而目前国内关于泛在学习的研究,还主要集中在基本理论、技术支持、环境构建、资源服务设计以及标准规范等问题,对泛在技术在教学应用方面的研究还不太突出。深化泛在技术的具体教学应用和实践,对泛在学习研究由理论走向实践,并向教育应用纵深发展具有积极的意义。泛在技术环境下教学系统的各个要素及其关系与传统教学环境存在着内在属性的差异,需要教育实践者亲身体察。华中师范大学教育技术学62名研究生,从体验的视角,在无线网络和笔记本电脑终端构建的学习环境中,探究泛在技术环境下的学习方式、教学交互、课堂参与以及教师角色。研究发现：在泛在技术环境下,学习者以问题为中心,选择自主探究和学习共同体协作为主的方式,进行以人为本的多维互动,其整体参与度呈现多波峰的波浪式变化规律,而个体则以显性参与为主,参与体验的终端数对学生的深层参与影响较大。同时,泛在技术对教师能力提出了更高要求,强化了教师作用,教师转变为集教学组织、引导、帮助和评价于一身的多元角色。但是为了形成平等、互助、协商的学习氛围,教师需适度参与学习者互动。  相似文献

An Evaluation of Using Data Set in Teaching and Learning within a Further and Higher Education Context     

Anwen Williams  Ioan Ap Dewi 《The Journal of Agricultural Education and Extension》2013,19(4):311-331

Abstract

This study aims to establish the effectiveness of an industrial data set in the delivery of an active approach to teaching and learning across a range of programme levels from NVQ to MSc within Further Education (FE) and Higher Education (HE) Institutions in North Wales. The result described in the paper reinforces in FE and HE the advantages of active learning involving an industrial data set as a link between theory and practice. Implementing the data set as a learning resource, combined with field visits allowed an active approach to teaching and learning. For the FE groups this was an established approach, while not so for the HE institutions. The use of an industrial data set by adopting an active approach was found to be effective, as judged by student satisfaction, enriched the educational experience for both FE and HE groups. The overall response for all questions by all groups for the Strongly Agree/Agree categories (SA/A) was between 86% and 95%. The Disagree (D) responses ranged from 0% to 3% and the Undecided/Blank/Not Applicable (UD/B/NA) ranged between 5% and 14%. Students found the lectures of interest and enjoyed active learning. The analysis has heightened the benefits of relating education to its respective industry and adopting an active approach for all programme levels within FE and HE.  相似文献   

Preparing for Renovation: Estimating Shelf Occupancy to Inform Decision Making Regarding the Redevelopment of Library Space     

William H. Weare Jr.  Paul Moffett  John P. Cooper 《资料收集管理》2013,38(3):168-181

University Library at Indiana University-Purdue University Indianapolis is in the process of repurposing space currently occupied by the print collection. To prepare for further reallocation of library space, reliable estimates of stacks space were needed. Two members of the Access Services Team applied systematic random sampling to estimate existing—and anticipated—empty shelf space. Results indicate that more than 30% of the shelf space is empty, while over 25% is occupied by journals, most of which are available in electronic format. These estimates would be used to inform decision making about shifting and/or withdrawal of library materials in preparation for the renovation of additional library spaces. The data-gathering process as well as data analysis and application used during the project may be applicable in other academic libraries.  相似文献

ACRL Framework: Integrations for Special Libraries     

Liz Fite  Esther Marie Jackson 《图书馆管理杂志》2013,53(8):881-890

Abstract

This column examines the potential applications of the ACRL Information Literacy Framework within special libraries. The authors address the current literature related to the ACRL Framework in special libraries and present two case studies detailing its usage in instruction and outreach initiatives. The first case study relates to an instruction session for interns at Mt. Cuba Center. The second case study relates to teaching users to edit Wikipedia at the New York Botanical Garden. Suggestions for how to integrate the ACRL Framework into future projects as well as suggestions for how information literacy can take on a greater role within the special libraries field are included in the conclusion.  相似文献   

Step by Step through the Scholarly Conversation: A Collaborative Library/Writing Faculty Project to Embed Information Literacy and Promote Critical Thinking in First Year Composition at Oregon State University     

Anne-Marie Deitering  Sara Jameson 《College & Undergraduate Libraries》2013,20(1-2):57-79

ABSTRACT

At Oregon State University, writing instructors and librarians collaboratively teach research writing and information literacy in first year composition courses. A four-week unit focuses on the connections between critical thinking, writing and learning, and information literacy. This article describes the process of developing, implementing, and refining this collaborative curriculum. By using assignments and texts that model a recursive critical research and writing process for students, librarians and writing instructors help students think more deeply and critically about their topics.  相似文献   

e-Science and Data Management Resources on the Web     

Sally A. Gore 《Medical reference services quarterly》2013,32(2):167-177

The way research is conducted has changed over time, from simple experiments to computer modeling and simulation, from individuals working in isolated laboratories to global networks of researchers collaborating on a single topic. Often, this new paradigm results in the generation of staggering amounts of data. The intensive use of data and the existence of networks of researchers characterize e-Science. The role of libraries and librarians in e-Science has been a topic of interest for some time now. This column looks at tools, resources, and projects that demonstrate successful collaborations between libraries and researchers in e-Science.  相似文献
