In recent years, professional organizations in the United States have suggested undergraduate mathematics shift away from pure lecture format. Transitioning to a student-centered class is a complex instructional undertaking especially in the proof-based context. In this paper, we share lessons learned from a design-based research project centering…

It is obvious that current tools in literature that are used to measure female's sexual quality of life focus only on the objective dimension of sexual function, failing to examine quality of life on a multidimensional level. The aim of this research is to examine the validity and reliability of the ADORE for Turkish society. In the methodological…

Purpose: Usability is one of the key concerns in the development of mobile learning applications. The aim of this paper is to design and validate a usability evaluation questionnaire (UEQ) for mobile learning applications. Design/methodology/approach: The UEQ was developed in four stages: selecting primary studies and extracting usability…

Student engagement is a central construct in education research, as it is a strong predictor and/or mediator of both cognitive and non-cognitive student outcomes. However, there remain questions among researchers about how to properly measure student engagement during lessons. Our study contributes to this discussion by presenting the development…

Objective: This study aimed to develop and test a scale for measuring the quality of blended learning models in higher education. Methods: This research adopts a sequential mixed-method approach to construct a new measurement scale. The first phase consisted of the inductive approach to identify the items, followed by exploratory factor analysis.…

Sexual and gender minoritized (SGM) adolescents negotiate their outness in various social contexts as they navigate a heteronormative system. For many SGM adolescents, outness is associated with peer victimization, while for others, it is associated with increased feelings of connectedness. To support SGM adolescents in their outness journey,…

Research in the social and behavioral sciences relies on a wide range of experimental and quasi-experimental designs to estimate the causal effects of specific programs, policies, and events. In this paper we highlight measurement issues relevant to evaluating the validity of causal estimation and generalization. These issues impact all four…

This study evaluated the efficacy of two proposed methods in an operational standard-setting study conducted for a high-stakes language proficiency test of the U.S. government. The goal was to seek low-cost modifications to the existing Yes/No Angoff method to increase the validity and reliability of the recommended cut scores using a convergent…

The current paper aims at developing and validating a Teacher Leadership Inventory (TLI). Adopting the theoretical-empirical strategy of instrument development, the procedure consisted of taking a sample of panel experts and undertaking six sequential empirical studies with sufficient samples of teacher leaders from China. After verifying content…

Many researchers have separately developed instruments to measure environmental characteristics such as attitudes, values, and knowledge. However, there is no instrument used to measure all these aspects in one comprehensive instrument. This study is meant to develop and validate a green character instrument which reveals student behavior and…

This study offers methodological synergy in the examination of factorial structure in second language (L2) research. It illustrates the effectiveness and flexibility of the recently developed exploratory structural equation modeling (ESEM) method, which integrates the advantages of exploratory factor analysis (EFA) and confirmatory factor analysis…

As community-based service-learning becomes more widely used in occupational therapy (OT) education, valid and reliable outcome measures are needed to ensure that student learning outcomes are meaningfully and consistently measured. Currently, educators may use instructor-developed questionnaires that have not been validated or employ narrowly…

School climate is an essential ingredient of student well-being and academic success. Although it has been studied extensively, only a few well-validated instruments are available for the assessment of school climate. The aim of this study was to assess the factor validity and measurement invariance of the Socio-educational Environment…

We compared the influence of open-book extended duration versus closed book time-limited format on reliability and validity of written assessments of pharmacology learning outcomes within our medical and dental courses. Our dental cohort undertake a mid-year test (30xfree-response short answer to a question, SAQ) and end-of-year paper (4xSAQ,…

Textual vignettes are a widely popular research tool, but they assume literacy and reading comprehension skills that limit their utility for both research with disadvantaged populations and cross-national research. We describe a new visual vignette approach, based on approaches used in studying populations with lower verbal ability, that avoids…
