Meta-analyses are systematic summaries of research that use quantitative methods to find the mean effect size (standardized mean difference) for interventions. Critics of meta-analysis point out that such analyses can conflate the results of low- and high-quality studies, make improper comparisons and result in statistical noise. All these…

More aggregate data on school performance is available than ever before, opening up new possibilities for applied researchers interested in assessing the effectiveness of school-level interventions quickly and at a relatively low cost by implementing comparative interrupted times series (CITS) designs. We examine the extent to which effect…

This research aimed to develop learning by e-learning system in Mahamakut Buddhist University, Mahavajiralongkorn Rajaviyalaya Campus. The method used in this study was Participatory Action Research that consisted of two cycles of planning, practice, observation, and reflection during two semesters in the academic year 2020. Twenty-one teachers…

Youth-led participatory action research (YPAR) is a theoretical-methodological approach that has been designed to promote positive development (e.g., well-being and health, social-emotional and cognitive development, academic or career advancement) and civic engagement among young people. Although YPAR holds particular promise, there has been…

Short comparative interrupted times series (CITS) designs are increasingly being used in education research to assess the effectiveness of school-level interventions. These designs can be implemented relatively inexpensively, often drawing on publicly available data on aggregate school performance. However, the validity of this approach hinges on…

Low persistence in science majors and limited participation in high-impact research experiences contribute to the nationwide underrepresentation of minorities in the science workforce, particularly jobs requiring a graduate degree. The Program for Excellence in Education and Research in the Sciences (PEERS) is an academic support program at the…

Treatment effect estimates from a "regression discontinuity design" (RDD) have high internal validity. However, the arguments that support the design apply to a subpopulation that is narrower and usually different from the population of substantive interest in evaluation research. The disconnect between RDD population and the…

Scholarship on the role of professional development opportunities for undergraduate students has highlighted the growing importance of internship programs. Different designs of internship programs have emerged as their numbers proliferate. Internship programs vary on key dimensions including integration of academic content, development of…

Programs involving research experiences for undergraduates (REUs) typically reflect either university-sponsored programs or programs funded by the National Science Foundation (NSF) that aim to facilitate students' research-based skill development. Despite the prevalence of research supporting the effectiveness of these programs, little research…

The landscape of medical education is continuously evolving, as are the needs of the learner. The appropriate use of research and evaluation is key when assessing the need for change and instituting one's innovative endeavours. This paper demonstrates how research seeks to generate new knowledge, whereas evaluation uses information acquired from…

Given the widespread use of non-experimental (NE) methods for assessing program impacts, there is a strong need to know whether NE approaches yield causally valid results in field settings. In within-study comparison (WSC) designs, the researcher compares treatment effects from an NE with those obtained from a randomized experiment that shares the…

This paper presents evidence confirming the validity of the RD design in the Reading Recovery study by examining the ability of the RD design to replicate the 1st grade results observed in the original i3 RCT focused on short-term impacts. Over 1,800 schools participated in the RD study over all four cohort years. The RD design used cutoff-based…

Qualitative comparative analysis (QCA) is gaining ground in evaluation circles, but the number of applications is still limited. In this article, we consider the challenges that can emerge during a QCA evaluation by drawing on our experience of conducting one in the field of development cooperation. For each stage of the evaluation process, we…

The purpose of this state-of-the-art review is to provide a general overview of recent research on time distribution and second language (L2) learning with special implications for classroom settings. Several studies have been performed to examine how to best distribute the hours of L2 practice to maximize learning by comparing conditions that…

Earlier research on Post-Secondary Enrollment Options (PSEO) has produced insights on policies, with emphasis on legislating the enrollment of high-school students who are taking college credits through the program. Previous studies have focused on what are considered impediments to the program, improving governance, and assessment, with a view on…
