A Simple Equation to Predict a Subscore's Value     

Richard A. Feinberg  Howard Wainer 《Educational Measurement》2014,33(3):55-56

Subscores are often used to indicate test‐takers' relative strengths and weaknesses and so help focus remediation. But a subscore is not worth reporting if it is too unreliable to believe or if it contains no information that is not already contained in the total score. It is possible, through the use of a simple linear equation provided in this note, to determine if a particular subscore adds enough value to be worth reporting.  相似文献   

SROI in the art gallery; valuing social impact     

Andrew Jackson  Richard McManus 《Cultural Trends》2019,28(2-3):132-145

ABSTRACT

This article considers a project that used the Social Return on Investment (SROI) methodology to describe and measure the social impact of Turner Contemporary art gallery in Margate, a coastal town in the South East of England. The article details the reasons why the methodology was chosen by the gallery, setting this in the context of the wider debate around evaluation and social impact reporting. A section of the research and analysis, which was carried out by COaST, a consultancy and research centre based within Canterbury Christ Church University, is described in detail, allowing the reader to understand the processes involved in this type of project and the kinds of outcomes that can be delivered using this method. Finally, an account is given of the impact the work had on the management of the gallery, and the ways in which the final report was used.  相似文献   

When Can We Improve Subscores by Making Them Shorter?: The Case Against Subscores with Overlapping Items     

Richard A. Feinberg  Howard Wainer 《Educational Measurement》2014,33(3):47-54

Subscores can be of diagnostic value for tests that cover multiple underlying traits. Some items require knowledge or ability that spans more than a single trait. It is thus natural for such items to be included on more than a single subscore. Subscores only have value if they are reliable enough to justify conclusions drawn from them and if they contain information about the examinee that is distinct from what is in the total test score. In this study we show, for a broad range of conditions of item overlap on subscores, that the value of the subscore is always improved through the removal of such items.  相似文献   

Unique contributions of eye-tracking research to the study of learning with graphics     

Richard E. Mayer 《Learning and Instruction》2010,20(2):167-171

The author examines the empirical, methodological, theoretical, and practical contributions of the six studies in this special issue on eye tracking as a tool to study and enhance multimedia learning. The design of learning environments involving graphics should be consistent with a research-based theory of how people learn and evidence-based principles of how to help people learn. Research using eye tracking offers a unique path to testing aspects of theories of multimedia learning, particularly concerning perceptual processing during learning. The studies reported in this special issue add to the evidence base on how people learn and think with graphics.  相似文献   

The development of case studies as a method within a longitudinal study of special educational needs provision in the Republic of Ireland     

Richard Rose  Michael Shevlin 《Journal of Research in Special Educational Needs》2016,16(2):113-121

When developing case studies within a longitudinal study of special educational needs provision within the Republic of Ireland, the authors were conscious of the critiques of the use of this approach within educational research. The difficulties associated with generalisation, challenges of ensuring trustworthiness and the possibilities of researcher bias have been identified as limiting factors in the presentation of case study data. In order to confront these limitations, the researchers developed a framework for case study development that aimed to provide a secure database and trustworthy interpretation in order to make assertions in relation to special educational needs provision. This paper describes this process and suggests that the need to develop safeguards in order to present case studies that have high degree of credibility is essential when using this approach. Furthermore, the transparency of research methods, a significant omission in many reports of research, is necessary in order to demonstrate the trustworthiness of data.  相似文献

Test–retest reliability of physiological parameters in elite junior distance runners following allometric scaling     

Richard C. Blagrove  Glyn Howatson  Philip R. Hayes 《European Journal of Sport Science》2017,17(10):1231-1240

This study aimed to quantify the intra-individual reliability of a number of physiological variables in a group of national and international young distance runners. Sixteen (8 male, 8 female) participants (16.7?±?1.4 years) performed a submaximal incremental running assessment followed by a maximal running test, on two occasions separated by no more than seven days. Maximal oxygen uptake (V?O_2max), speed at V?O_2max (km?h^?1), running economy and speed and heart rate (HR) at fixed blood lactate concentrations were determined. V?O_2max and running economy were scaled for differences in body mass using a power exponent derived from a larger cohort of young runners (n?=?42). Running economy was expressed as oxygen cost and energy cost at the speed associated with lactate turnpoint (LTP) and the two speeds prior to LTP. Results of analysis of variance revealed an absence of systematic bias between trials. Reliability indices showed a high level of reproducibility across all parameters (typical error [TE] ≤2%; intra-class correlation coefficient >0.8; effect size <0.6). Expressing running economy as energy cost appears to provide superior reliability than using oxygen cost (TE ～1.5% vs. ～2%). Blood lactate and HR were liable to daily fluctuations of 0.14–0.22?mmol?L^?1 and 4–5?beats?min^?1 respectively. The minimum detectable change values (95% confidence) for each parameter are also reported. Exercise physiologists can be confident that measurement of important physiological determinants of distance running performance are highly reproducible in elite junior runners.  相似文献
