Differential item functioning (DIF) can undermine the validity of cross-lingual comparisons. While a lot of efficient statistics for detecting DIF are available, few general findings have been found to explain DIF results. The objective of the article was to study DIF sources by using a mixed method design. The design involves a quantitative phase…

This small "n" observational study used a concurrent mixed methods approach to address a void in the literature with regard to the qualitative meaningfulness of the data yielded by absolute magnitude estimation scaling (MES) used to rate subjective stimuli. We investigated whether respondents' scales progressed from less to more and…

Achievement goal theory is one of the most popular theories of achievement motivation. Techniques researchers have used to assess goals include standardized questionnaires and interviews. One curious finding is that participants whose self-report questionnaire responses strongly indicate they operate with a performance goal do not make performance…

A concurrent mixed methods design, giving equal priority to both quantitative and qualitative methods, was used to investigate some of the factors that influence academic achievement of Native Hawaiian students in public schools in the state of Hawai'i. School-level instructional strategies, curricula, policies, and other variables that…

In recent years, combining quantitative and qualitative research methods in the same study has become increasingly acceptable in both applied and academic psychological research. However, a difficulty for many mixed methods researchers is how to integrate findings consistently. The value of using a coherent framework throughout the research…

This article presents an innovative sequential mixed methods approach to researching the experiences of U.K. adults with chronic health conditions seeking health information online. The use of multiple methods integrated within a single study ensured that the focus of the research was emergent and relevant and ultimately provided a more complete…

The Effective Classroom Practice project aimed to identify key factors that contribute to effective teaching in primary and secondary phases of schooling in different socioeconomic contexts. This article addresses the ways in which qualitative and quantitative approaches were combined within an integrated design to provide a comprehensive…

Substantial integration of quantitative and qualitative data and findings in mixed methods studies is seldom seen, although maximizing the potential of the approach depends on this. An absence of exemplars has been identified as among a number of factors that currently impede integration in studies carried out by researchers using the approach.…

Teaching is emotional, especially when teachers must change their practices. Past research on emotions and change in the general population has been predominately quantitative. Research about teachers' emotions, however, has been predominately qualitative. To draw on both these approaches, this mixed methods study examined 50 elementary teachers'…

This article argues that a mixed methods approach is useful in understanding the complexity that underlies teachers' commitment to environmental education. Using sequential and concurrent procedures, the authors demonstrate how different methodological approaches highlighted different aspects of teacher commitment. The quantitative survey examined…
