Data-mined models often achieve good predictive power, but sometimes at the cost of interpretability. We investigate here if selecting features to increase a model's construct validity and interpretability also can improve the model's ability to predict the desired constructs. We do this by taking existing models and reducing the feature set to…

The authors utilized an experimental design across six sections of a managerial communications course (N = 173) to test the impact of instructor verbal aggressiveness and class attendance policies on student class attendance. The experimental group received a policy based on the principle of social proof (R. B. Cialdini, 2001), which indicated…

Background: Treatment implementation is not just one thing but rather is a multifaceted process that includes treatment delivery, treatment receipt, and treatment adherence. As such, local variations in implementation and service delivery of interventions are an inevitable. Purpose: To assess implementation fidelity of a multi-site experiential…

Background: The relationship between sport and exercise science (SES) and health and physical education (HPE) has been of interest to those of us involved in the general field of human movement studies in higher education for at least the last four decades. Purpose: The purpose of this research was to determine how the proposed merging of the…

Prior meta-analyses have found a moderate but robust relationship between alliance and outcome across a broad spectrum of treatments, presenting concerns, contexts, and measurements. However, there continues to be a lively debate about the therapeutic role of the alliance, particularly in treatments that are tested using randomized clinical trial…

This study investigated whether students who engage in inquiry dialogue with others improve their performance on various tasks measuring argumentation development. The study used an educational environment called Philosophy for Children (P4C) to examine specific theoretical assumptions regarding the role dialogic interaction plays in the…

The following narrative reflects on the dilemmas and problems faced by inexperienced researchers working within the field of education. Focusing on a research project completed in fulfilment of an MA in Teaching and Learning, the article recounts the decisions made by one emergent researcher and evaluates how far the chosen methods may have helped…

Stemming from the UNCRC, childhood researchers have proposed a variety of methodological strategies for upholding children's rights and understanding their perspectives. This paper aims to advance the conversation on engaging children's perspectives by presenting data collection methods used in a qualitative study exploring children's special…

Gender matters in the classroom, but not in the way people may assume; girls are outperforming boys. Identity-based motivation (IBM) theory explains why: People prefer to act in ways that feel in-line with important social identities such as gender. If a behavior feels identity-congruent, difficulty is interpreted as meaning that the behavior is…

Background: This article describes the process of including people with intellectual disabilities (ID) and carers of people with ID as researchers and participants in randomised controlled trial (RCT) research. People with ID are rarely involved in research about their health, either as researchers or participants. Carers are often included as…

How can science instructors prepare students for the statistics needed in authentic inquiry labs? We designed and assessed four instructional modules with the goals of increasing student confidence, appreciation, and performance in both experimental design and data analysis. Using extensions from a just-in-time teaching approach, we introduced…

Educational researchers, like other academic investigators, are expected to carry out research in an ethical manner. This paper draws on the author's experience of conducting a research study related to social justice, which examines intergenerational dynamics and education amongst British Asian families. It discusses the importance of ethical…

This article examines changes in the research design, sample size, and precision between the planning phase and implementation phase of group randomized trials (GRTs) funded by the Institute of Education Sciences. Thirty-eight GRTs funded between 2002 and 2006 were examined. Three studies revealed changes in the experimental design. Ten studies…

Concerted efforts have been made within teacher preparation programs to integrate teaching with technology into the curriculum. Unfortunately, these efforts continue to fall short as teachers' application of educational technology is unsophisticated and not well integrated. The most prevalent approaches to integrating technology tend to ignore…

There exists much debate in the area of hybrid and online developmental mathematics. Researchers believe that the best method of delivery of developmental mathematics is the traditional, instructor-based classroom setting. This study examined the success of developmental mathematics students in traditional, hybrid, and online classroom…
