Across the world, teacher quality has come to be recognised as one of the most important variables affecting student outcomes; consequently, the regulation of entry into the profession is the subject of iterative review. The traditional 'one-off' interview, involving an interviewee and two or more interviewers, is a common, but not unproblematic,…

Background: Existing literature failed to explore the parental expectations and experiences from physiotherapy for children with Down syndrome. Hence, we aimed to validate a semi-structured interview guide to explore parental experiences and expectations from physiotherapy for children with Down syndrome. Methods: A 28-item interview guide was…

The current study evaluated a brief, informant-based autism interview: the Developmental, Dimensional and Diagnostic Interview -- Adult Version (3Di-Adult). Feasibility, reliability and validity of the Dutch 3Di-Adult was tested amongst autistic participants (n = 62) and a non-autistic comparison group (n = 30) in the Netherlands. The 3Di-Adult…

It is a necessity for a researcher to ensure that the validity and reliability of the study is met to prove a discovery. However, there are still qualitative researchers who are still reckless and do not emphasize the concept of validity and reliability when designing, collecting, and analysing the research findings. The quality of a qualitative…

Validity refers to the extent to which a given study reflects the dominant values of a research community regarding what constitutes "good" research. Methodological texts on qualitative research provide a wide range of criteria and strategies to help qualitative researchers validate their studies. Given the importance of these strategies…

This paper reports on a design oriented study conducted in close collaboration between two researchers and three preschool teachers. Within this study, a play-based interview script was designed in accordance with theoretically driven principles. Based on this script, the preschool teachers conducted interviews with children from three preschools…

Places to study at medical schools are scarce, which makes well-designed selection procedures employing criteria with predictive validity for good students and doctors necessary. In Germany, the pre-university grade point average (pu-GPA) is the main selection criterion for medical school application. However, this is criticised. According to a…

Response process validity evidence can provide researchers with insight into how and why participants interpret items on instruments such as tests and questionnaires. In chemistry education research literature and the social sciences more broadly, response process validity evidence has been used and reported in a variety of ways. This paper's…

Researchers need to know what is an appropriate sample size for interview work, but how does one decide upon an acceptable number of people to interview? This question is not relevant to case study work where one would typically interview every member of a case, or in situations where it is both desirable and feasible to interview all target…

This paper makes available to the broader educational community the instruments which have been originally designed and validated within the European project "CLIL for all: Attention to diversity in bilingual education" ("ADiBE") to determine how diversity is being catered to across a broad array of CLIL contexts in European…

For individuals with autism spectrum disorder (ASD), behavioral inflexibility can affect multiple domains of functioning and family life. The objective of this study was to develop and validate a clinical interview version of the Behavioral Inflexibility Scale. Trained interviewers conducted interviews with parents of 144 children with ASD and 70…

Performance-based assessment is a common approach to assess the development and acquisition of practice competencies among health professions students. Judgments related to the quality of performance are typically operationalized as ratings against success criteria specified within a rubric. The extent to which the rubric is understood,…

Onwuegbuzie and colleagues proposed the Instrument Development and Construct Validation (IDCV) process as a mixed methods framework for creating and validating measures. Examples applying IDCV are lacking. We provide an illustrative case integrating the Rasch model and cognitive interviews applied to the development of the Transformative…

Using Kane's interpretive argument model and Messick's validity argument approach, this study rigorously examined faculty and PhD candidate's perspectives on PhD admission interviews in Iranian universities. We interviewed 10 professors and PhD interviewees which provided comprehensive insight into nuanced perspectives. We conducted rigorous…

Mathematics education researchers frequently use task-based interviews to gain insight into mathematicians' practice. However, there are a number of factors that should prevent mathematics educators from extrapolating how individual mathematicians respond to researcher-generated tasks in laboratory conditions, to how mathematicians practice their…
