The study aimed to conduct a systematic literature review to identify the trends, impacts, and challenges of mobile microlearning (MML) research. Using five academic databases from the fields of social science, engineering, and medical science as search sources, 26 scholarly articles, published between 2015 and 2020, were retrieved. The study…

Many teacher education researchers have expressed concerns with the lack of rigorous impact evaluations of teacher preparation practices. I summarize these various concerns as they relate to issues of internal validity, external validity, and measurement. I then assess the prevalence of these issues by reviewing 166 impact evaluations of teacher…

The What Works Clearinghouse (WWC) identifies existing research on educational interventions, assesses the quality of the research, and summarizes and disseminates the evidence from studies that meet WWC standards. The WWC aims to provide enough information so educators can use the research to make informed decisions in their settings. This…

As the number of publicly funded early childhood education (ECE) programs increases, policymakers will need empirical evidence to justify the taxpayer investment. Such justification will require a stronger understanding of the essential components of an ECE program's design, as well as solid evidence on which components, or constellations of…

Suppose an education researcher wants to test the impact of a high school drop-out prevention intervention in which at-risk students attend classes to receive intensive summer school instruction. The district will allow the researcher to randomly assign students to the treatment classes or to the control group. Half of the students (the treatment…

This paper provides practical guidance for researchers who are designing and analyzing studies that randomize schools--which comprise three levels of clustering (students in classrooms in schools)--to measure intervention effects on student academic outcomes when information on the middle level (classrooms) is missing. This situation arises…

Federal laws mandate that students with cognitive disabilities receive instruction in academic skills and also support the importance of teaching self-determination. The purpose of this literature review was to synthesize intervention research examining effects of self-determination interventions on academic skills for students with cognitive…

Mixed methods research has increased in popularity over the past 20 years. Literature reveals that exploratory qualitative analysis followed by confirmatory survey research is common and concurrent studies outnumber longitudinal design. Longitudinal studies using quantitative and qualitative methods in sequence for exploratory purposes are rare,…

Before schools and districts invest their scarce resources in the products that educational researchers have developed, teachers, administrators, and community members need to become informed consumers of educational research. This article strives to bridge the gap between researchers and practitioners by exploring how to become an informed…

This paper argues that inferential statistical analyses as part of group research designs do not provide the kinds of data that are useful in determining the efficacy of clinical intervention with individuals having communication disorders. Replication studies are seen as providing a more fruitful approach to ascertaining the efficacy of clinical…

Perhaps no facet of long-term care (LTC) research has received as much attention as the evaluation of community-based LTC demonstrations. Recent thinking has called into question the validity and policy relevance of the findings of these studies, yet their efforts will continue to receive strong financial backing. The time has come for LTC…

A repeated measures design was used to assess the effects of a methadone maintenance program in several California locations. Subjects were 720 Chicano and Anglo men and women participating in rehabilitation programs for heroin addicts. The subjects were interviewed between 1978-1981, and the average follow-up time after initial treatment was 4-6…

In response to 1986 state legislation calling for improvements in college effectiveness and accountability, the California Community Colleges began various efforts to promote the evaluation of matriculation. One effort, the Matriculation Local Research Options Project, was formed in 1989 to develop models for local evaluation of matriculation and…

Following a discussion of various methods of evaluating the effectiveness of developmental programs, this paper presents a research design for the evaluation of a developmental math program. First, the paper examines the objectives and benefits of conducting formative and summative program evaluations. The paper then identifies the single group…

The purpose of this conference was to provide a framework for improving the quality and increasing the quantity of nutrition education research. Emphasis was placed upon examining the research process from the standpoint of theory or model building. Presentations were made on: (1) "Nutrition Education Research Policy in Washington"…
