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…

In this research we attempt to empirically validate a model - using signalling theory - that explains important antecedents and consequences of students' attitude towards internationally accredited business schools. Using a quasi-experimental design, we collected data from undergraduate students of eight countries across four scenarios. The…

We evaluated structural, construct, and concurrent validity evidence for State-Interpersonal Reactivity Index scores among 208 telemental health counselors. Confirmatory factor analysis results supported a three-factor model. Partial correlation analyses yielded evidence for construct and concurrent validity evidence for scores. We discuss…

Research Findings: A growing number of stakeholders in early childhood education (ECE) rely on self-assessment to assess and improve the quality of ECE. In this systematic review, we investigated the reliability and validity of self-assessment in ECE, summarizing findings from 27 publications. We meta-analytically synthesized findings from 25…

Research self-efficacy is a key component of college students' career development. This study's purpose was to develop and begin to construct a validity argument for scores from the Sources of Research Self-Efficacy (SRSE) scale in college students. We explored validity evidence for SRSE scores from 719 undergraduate and graduate students based on…

The current study compared American, Korean, and Indonesian middle and high school students' CS attitudes. Concurrently, this study also examined whether the items in the CS attitudes scale exhibit country and gender measurement biases. We gathered data on CS attitudes from middle and high school students in the US, Korea, and Indonesia. The…

Despite the recognized importance of mathematical proof in secondary education, there is a limited but growing body of literature indicating how preservice secondary mathematics teachers (PSMTs) view proof and the teaching of proof. The purpose of this survey research was to explore PSMTs' knowledge and beliefs about proof and proof teaching in…

The Program for the International Assessment of Adult Competencies (PIAAC) is a multicycle survey of adult skills and competencies sponsored by the Organization for Economic Cooperation and Development (OECD). The survey examines a range of basic skills in the information age and assesses these adult skills consistently across participating…

Despite the central role of proofs in mathematics, research often shows that school textbooks offer limited support for the teaching and learning of proof-related reasoning. This study contributes to this field of research by studying Swedish and Finnish upper secondary textbooks on logarithms and combinatorics. Justifications in expository…

Transactional validity, a common approach in participatory research, is attained when preliminary analyses of research results are discussed with research participants and their feedback is incorporated in the analysis. Member checking is one way of achieving transactional validity, which has been heralded as a stronger version of validity reached…

Previous research on bilingual mathematics education has proposed that as children "language mathematics" they use multiple sources of meaning. In this paper, we focus on lexical inventions--bilingual children's made up words that are not formally defined or used but follow the phonology and morphology of a language--as a source of…

This study investigated Chinese international students' sense of belonging by exploring the cultural and cognitive validity of a commonly used sense of belonging instrument, namely the Hoffman et al.'s (2002) Sense of Belonging Scale. Cognitive interviewing procedures supplemented with open-ended questions were administered to 20 sophomore- and…

Questionnaires routinely measure unipolar and bipolar constructs using rating scales. Such rating scales can offer odd numbers of points, meaning that they have explicit middle alternatives, or they can offer even numbers of points, omitting the middle alternative. By examining four types of questions in six national or regional telephone surveys,…

Proof and argumentation are essential components of learning mathematics, and technology can mediate students' abilities to learn. This systematic literature review synthesizes empirical literature which examines technology as a support for proof and argumentation across all content domains. The themes of this review are revealed through analyzing…

This article presents the findings of a systematic qualitative analysis of research in the ethics of digital trace data use in learning and education. From the resulting analysis of 77 peer-reviewed studies, we (1) map the characteristics of research by study type, academic community, institutional setting, and national context; (2) identify the…
