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…

There is a growing recognition of the need for interventions to improve the healthcare of autistic adults. However, there is a dearth of validated measures to evaluate such interventions. Our objectives were to use a community-based participatory research approach to create an accessible set of patient- and proxy-reported instruments to measure…

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,…

Bell's theorem is a topic of perennial fascination. Publishers and the general public have a steady appetite for approachable books about its implications. The scholarly literature includes many analogies to Bell's theorem and simple derivations of Bell inequalities, and some of these simplified discussions are the basis of interactive web pages.…

Providing assessment validity information to decision makers in a clear and useful format is an ongoing challenge for the educational and psychological measurement community. We identify issues with a previous approach to a graphical presentation, noting that it is mislabeled as presenting incremental validity, when in fact it displays the effects…

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…

Validity is a fundamental consideration of test development and test evaluation. The purpose of this study is to define and reify three key aspects of validity and validation, namely test-score interpretation, test-score use, and the claims supporting interpretation and use. This study employed a Delphi methodology to explore how experts in…

Learning affective state is determinate to online learning. Different affective states are associated with different online learning behaviors. Given the behavioral indicators of different affective states are still to be explored, this study constructed a data-driven online learning affective state detector by analyzing the learning log data of…
