Assessing student knowledge based on their writing using traditional qualitative methods is time-consuming. To improve speed and consistency of text analysis, we present our mixed methods development of a machine learning predictive model to analyze student writing. Our approach involves two stages: first an exploratory sequential design, and…

A quantitative approach to social network analysis involves the application of mathematical and statistical techniques and graphical presentation of results. Nonetheless--as with all sciences--subjectivity is an integral aspect of network analysis, manifested in the selection of measures to describe connection patterns and actors' positions (e.g.,…

Recently, a debate has arisen around what can be called the "indistinguishability thesis," that is, the claim that it is impossible to distinguish between qualitative and quantitative research. In contrast, this article argues that the inability to define simple, sharp boundaries around qualitative and quantitative research does not…

This article outlines the rationale for adopting a mixed methods approach within randomized controlled trials (RCTs) and explores challenges associated in doing so. Taking the example of the EASE Back feasibility and pilot study (Evaluating Acupuncture and Standard care for pregnant womEn with "BACK" pain: ISRCTN49955124), we detail why…

By distinguishing between a survey and--a newly introduced term--a "probe," we recast the relationship between qualitative and quantitative approaches to social science. The difference turns on the "uniformity" of the phenomenon being examined. Uniformity is a fundamental idea underlying all scientific research but is rarely…

Background: A systematic literature review was conducted on mixed methods area. Objectives: The overall aim was to explore how qualitative information from interviews has been analyzed using quantitative methods. Methods: A contemporary review was undertaken and based on a predefined protocol. The references were identified using inclusion and…

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…

This research, based on a case study of vulnerable children in Korea, used a mixed methods transformative approach to explore strategies to support and help disadvantaged children. The methodological approach includes three phases: a mixed methods contextual analysis, a qualitative dominant analysis based on Sen's capability approach and critical…

Indigenous communities raise concerns that they are overresearched and tired of research always asking the same questions and reproducing the same answers, thus pressuring researchers to open the discourse on mixed methods research so as to enable new debates and approaches to emerge. A postcolonial indigenous paradigm provides a theoretical…

Over a decade ago, researchers in Roma studies shifted their approach, from an exclusionary stance to a more communicative one. Despite major positive changes since then, researchers still do not adequately reflect the voices of the majority of the world's Roma. In this article, we draw on a communicative mixed methods case study, conducted within…

Using both quantitative and qualitative analyses, we examine the role of a college access intervention in the enrollment and persistence outcomes of low-income students in Chile modeled partially after a Texas admissions program. We find that, although students from the program have a mean cumulative GPA significantly lower than that of their…

Increasing recognition of the role of social conditions in health has led to calls for methods that can be used to change social conditions. Popular education has demonstrated great promise as a methodology that can be used to address the underlying social and structural determinants of health. To date, most studies of popular education have used…

This convergent parallel design mixed methods case study of four community colleges explores the relationship between organizational capacity and implementation of data-driven decision making (DDDM). The article also illustrates purposive sampling using replication logic for cross-case analysis and the strengths and weaknesses of quantitizing…

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…

Although combining methods is nothing new, more contributions about why and how to mix methods for validation purposes are needed. This article presents a case of validating the inferences drawn from the Participatory Evaluation Measurement Instrument, an instrument that purports to measure stakeholder participation in evaluation. Although the…
