Digital Module 05: Diagnostic Measurement—The G‐DINA Framework https://ncme.elevate.commpartners.com     

Wenchao Ma  Jimmy de la Torre 《Educational Measurement》2019,38(2):114-115

In this ITEMS module, we introduce the generalized deterministic inputs, noisy “and” gate (G‐DINA) model, which is a general framework for specifying, estimating, and evaluating a wide variety of cognitive diagnosis models. The module contains a nontechnical introduction to diagnostic measurement, an introductory overview of the G‐DINA model, as well as common special cases, and a review of model‐data fit evaluation practices within this framework. We use the flexible GDINA R package, which is available for free within the R environment and provides a user‐friendly graphical interface in addition to the code‐driven layer. The digital module also contains videos of worked examples, solutions to data activity questions, curated resources, a glossary, and quizzes with diagnostic feedback.  相似文献   

A meta-cognitive approach to doping in sports: The effects of thought validation on attitudes related to doping     

Javier Horcajo  David Santos  Joshua J. Guyer  Rafael Mateos 《Journal of sports sciences》2020,38(19):2242-2252

ABSTRACT

To better understand doping-related attitude change, it is important to consider not only the amount of thinking (i.e., elaboration) done by message recipients, but also the favourability of their thoughts in response to the proposal, as well as the perceived validity in their thoughts. The main goal of the present study was to analyse the effects of a meta-cognitive process (i.e., thought validation) on attitudes related to doping. Thus, we randomly assigned participants to read a message either against or in favour of legalising several doping behaviours. Participants listed their thoughts regarding the proposal and indicated the perceived validity in their thoughts, then reported their attitudes. As hypothesised, the message against legalisation elicited more unfavourable thoughts and attitudes than the message in favour of legalisation. Most relevantly, the effects of the message direction on attitudes were greater for participants with higher (vs. lower) levels of thought validity. Furthermore, consistent with the thought validation process, results revealed that thought favourability was a better predictor of attitudes for participants with higher (vs. lower) perceived thought validity, indicating that perceiving one’s thoughts as valid plays an important role in persuasion. These findings provide novel insights for research and interventions regarding doping in sports.  相似文献

Validation of a self-perceived media competence instrument for pre-service teachers / Validación de un instrumento de autopercepción de competencia mediática para docentes en formación     

Julio-César Mateus  Wilson Hernández-Breña  Mònica Figueras-Maz 《Cultura y Educación》2019,31(2):436-464

Abstract

Key to guaranteeing the fundamental human rights of freedom of expression and information is the development of media competence, particularly in schools. Training teachers in the area of media competence is particularly important for developing these skills in the broader citizenry. In order to provide educators and educational policymakers with a useful diagnostic tool, we have designed a self-perception questionnaire. The questionnaire was applied to a sample of Peruvian education students (N = 501). On the one hand, the results confirm the construct’s coherence, validity and instrumental reliability. On the other hand, they allow us to propose a theoretically based update to the way in which this construct is interpreted and applied, confirming the multidimensionality of media competence. Finally, we use this empirical evidence to discuss the integral, transversal and ecological status of media competence.  相似文献   

Assessing postgraduate student perceptions and measures of learning in a peer review feedback process     

Genevieve Simpson  Julian Clifton 《Assessment & Evaluation in Higher Education》2016,41(4):501-514

Peer review feedback, developed to assist students with increasing the quality of group reports and developing peer review skills, was added to a master’s level Climate Change Policy and Planning unit. A pre- and post-survey was conducted to determine whether students found the process a valuable learning opportunity: 87% of students responding to the post-review survey indicated they saw benefit in both developing and receiving peer review feedback. Peer review design minimising the potential for plagiarism resulted in low levels of student concern surrounding plagiarism. Marks allocated by students were valid (consistent with the lecturer) and were generally reliable; however, distribution of marks had a higher variance where group report quality was low. Training on completing the peer review template could result in more reliable feedback. Consistent with the literature, the feedback developed during the peer review process focused on style and presentation preferentially to content. Seven out of eight group reports improved between report submissions, with all groups responding to peer review feedback. Peer review feedback and changes made to group reports indicated students had limited capacity to judge the quality of referencing and critical analysis.  相似文献

Validating Student Score Inferences With Person‐Fit Statistic and Verbal Reports: A Person‐Fit Study for Cognitive Diagnostic Assessment     

Ying Cui  Mary Roduta Roberts 《Educational Measurement》2013,32(1):34-42

The goal of this study was to investigate the usefulness of person‐fit analysis in validating student score inferences in a cognitive diagnostic assessment. In this study, a two‐stage procedure was used to evaluate person fit for a diagnostic test in the domain of statistical hypothesis testing. In the first stage, the person‐fit statistic, the hierarchy consistency index (HCI; Cui, 2007 ; Cui & Leighton, 2009 ), was used to identify the misfitting student item‐score vectors. In the second stage, students’ verbal reports were collected to provide additional information about students’ response processes so as to reveal the actual causes of misfits. This two‐stage procedure helped to identify the misfits of item‐score vectors to the cognitive model used in the design and analysis of the diagnostic test, and to discover the reasons of misfits so that students’ problem‐solving strategies were better understood and their performances were interpreted in a more meaningful way.  相似文献   

Validation of a laboratory and hospital information system in a medical laboratory accredited according to ISO 15189     

Biljak VR  Ozvald I  Radeljak A  Majdenic K  Lasic B  Siftar Z  Lovrencic MV  Flegar-Mestric Z 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2012,22(1):86-91

Introduction

The aim of the study was to present a protocol for laboratory information system (LIS) and hospital information system (HIS) validation at the Institute of Clinical Chemistry and Laboratory Medicine of the Merkur University Hospital, Zagreb, Croatia.

Materials and methods:

Validity of data traceability was checked by entering all test requests for virtual patient into HIS/LIS and printing corresponding barcoded labels that provided laboratory analyzers with the information on requested tests. The original printouts of the test results from laboratory analyzer(s) were compared with the data obtained from LIS and entered into the provided template. Transfer of data from LIS to HIS was examined by requesting all tests in HIS and creating real data in a finding generated in LIS. Data obtained from LIS and HIS were entered into a corresponding template. The main outcome measure was the accuracy of transfer obtained from laboratory analyzers and results transferred from LIS and HIS expressed as percentage (%).

Results:

The accuracy of data transfer from laboratory analyzers to LIS was 99.5% and of that from LIS to HIS 100%.

Conclusion:

We presented our established validation protocol for laboratory information system and demonstrated that a system meets its intended purpose.  相似文献   

Understanding outcome-based education changes in teacher education: evaluation of a new instrument with preliminary findings     

Christopher Deneen  Gavin T.L. Brown  Trevor G. Bond  Ronnie Shroff 《Asia-Pacific Journal of Teacher Education》2013,41(4):441-456

Outcome-based education (OBE) is a current initiative in Hong Kong universities, with widespread backing by governments and standards bodies. However, study of students’ perceptions of OBE and validation of understanding these perceptions are lacking. This paper reports on the validation of an OBE-specific instrument and resulting preliminary findings. Instrument responses (n = 89) were analysed using Rasch and exploratory/confirmatory factor analyses. Both approaches identified two dimensions (i.e. evaluation and comparison). Challenges and modifications to the instrument items and their relationships to constructs are discussed. Preliminary findings suggest students did not perceive significant differences between OBE and traditionally organised courses. Lack of explicit discussion of OBE with the students may have denied students the ability to make fully informed evaluations of OBE innovations. Implications for instrument validation and evaluation of initiatives in an OBE context are discussed as is the broader issue of transparency in teacher education curriculum design and implementation.  相似文献   

Assessing mentoring in organizations: an evaluation of commercial mentoring instruments     

Brad Gilbreath  Gail L. Rose  Kim E. Dietrich 《Mentoring & Tutoring: Partnership in Learning》2013,21(4):379-393

The purpose of this article is to inform readers about the types of instruments available for assessing and improving mentoring in organizations. Extensive review of the psychological, business and medical literature was conducted to identify commercially published, practitioner‐oriented instruments. All of the instruments that were identified – including the Alleman mentoring activities questionnaire, Mentoring in the moment, Mentoring skills assessment, and Principles of adult mentoring scale – are evaluated herein. Each instrument’s target audience, raters, subscales, response options, psychometric properties, and relative strengths and weaknesses are described. Although these instruments are reported to be used extensively, evidence of their validity is not always available. This review presents information that, in combination with first‐hand inspection of the instruments, should enable practitioners to differentiate between instruments that may be a fit for their needs from those that are not. Furthermore, it may introduce academic readers to instruments that are not covered in the scholarly literature in spite of their common use for non‐research purposes.  相似文献
