Many of the studies used to support the claim that student evaluations of teaching are reliable measures of teaching effectiveness have frequently calculated inappropriate reliability coefficients. This paper points to three coefficients that would be appropriate depending on if student evaluations were used for formative or summative purposes.…

Coefficient omega and alpha are both measures of the composite reliability for a set of items. Unlike coefficient alpha, coefficient omega remains unbiased with congeneric items with uncorrelated errors. Despite this ability, coefficient omega is not as widely used and cited in the literature as coefficient alpha. Reasons for coefficient omega's…

The chapter argues for redefining the term "persistence" as it relates to MOOCs and considers how different measures produce different results in the research; it closes with a review of research on persistence in MOOCs.

Many ways can be done to address the problem of students, one of them involving the students themselves (peer counselor). It required a standard model that can be applied by students as guidelines for the implementation of the guidance. Validity of the module it must be done according to the rules of various scientific tests. State University of…

The aim of this study is to identify and provide a clear idea about the helpful ways in determining the truth (or reliability) of arguments in the situations where it is necessary to make a decision. In this paper, we use systemic, structural-functional, activity approaches, methods of analysis, synthesis, moreover we discuss the works of…

This research was conducted to investigate 7th grade students' problem solving success rates on proportional reasoning problems and whether these success rates change with different problem types. 331 randomly selected students of grade seven participated in this study. A problem test which contains three different types of missing value (direct…

Educational research often requires mixing different research methodologies to strengthen findings, better contextualize or explain results, or minimize the weaknesses of a single method. This article provides practical guidelines on how to conduct such research in biology education, with a focus on mixed-methods research (MMR) that uses both…

The current study was designed to evaluate a rotating momentary time sampling (MTS) data collection system. A rotating MTS system has been used to measure activity preferences of preschoolers but not to collect data on responses that vary in duration and frequency (e.g., talking). We collected data on talking for 10 preschoolers using a 5-s MTS…

The main points of Sijtsma and Green and Yang in Educational Measurement: Issues and Practice (34, 4) are that reliability, internal consistency, and unidimensionality are distinct and that Cronbach's alpha may be problematic. Neither of these assertions are at odds with Davenport, Davison, Liou, and Love in the same issue. However, many authors…

This study concerned validating academic integrity survey (AIS), a measure developed in 2010 to investigate academic integrity practices in a Malaysian university. It also examined the usefulness of the measure across gender and nationality of the participants (undergraduates of Nigerian and Malaysian public universities). The sample size…

This book provides an overview and discussion of the evidence base of effective school inspections; reflecting on issues of validity and reliability of school inspections in relation to school effectiveness research, unintended consequences and emergent roles and responsibilities of Inspectorates of Education. Chapters include findings from…

The goal of this case study was to introduce students to ways to conduct research on parent child cognitive learning interactions. To this end, the case study begins with an overview of the theoretical and empirical work supporting the development of my research program on parent child cognitive learning interaction research and continues with a…

This study examined the reliability and validity of the Classroom Assessment Scoring System-Secondary (CLASS-S) in Finnish classrooms. Trained observers coded classroom interactions based on video recordings of 46 Grade 6 classrooms (450 cycles). Concurrent associations were investigated with respect to teacher self-ratings (e.g., efficacy beliefs…

Purpose: This study reports the psychometric development of the Cantonese versions of the English Computerized Revised Token Test (CRTT) for persons with aphasia (PWAs) and healthy controls (HCs). Method: The English CRTT was translated into standard Chinese for the Reading--Word Fade version (CRTT-R-[subscript WF]-Cantonese) and into formal…

In this study, issues of validity and reliability of a wide range of instruments used to measure technological pedagogical content knowledge level of English teachers were discussed. To this end, the search in the databases of ERIC, ScienceDirect, Scopus, EBSCOhost, and Web of Science was conducted. As a result of applying a set of criteria to…
