Professional standards related to outcomes assessment call for student affairs professionals to use research to inform programming. If professionals are to rely on research to build programs that positively impact student learning outcomes, the research should be credible. We examined the quality of program effectiveness research available for…

This dissertation is guided by my driving research question: what works for whom in education and why? I examine issues of instruction, assessment, and research approaches that begin to answer this question. Study 1 examines a classroom intervention's child x instruction interactions. Study 2 examines underlying cognitive factors, including…

Adult education's mission is a critical one. It seeks to provide the large and diverse population of adults who lack basic skills, a high school credential, or English language skills with the competencies they need to be productive workers, family members, and citizens. Federally funded adult education serves learners in three types of programs:…

Title II of the Workforce Innovation and Opportunity Act of 2014 directs the federal government to conduct a national assessment of adult education, including activities to understand the extent to which adult education strategies positively affect learners. A systematic review of the research on the effectiveness of particular strategies in adult…

During the four decades since the founding of the National Center for Developmental Education (NCDE; originally the Center for Developmental Education), research related to the field has continued to expand and mature. As a research center focused on using research to inform and improve practice, the NCDE's 40th Anniversary timeline presents…

This annual newsletter contains updates on the latest Community College Research Center (CCRC) research, new publications and details of upcoming presentations at major conferences. The feature article in this issue, "Improving Community College Assessment and Placement," by Thomas Bailey, discusses how the process of assessment and…

The major objective of this paper is to demonstrate the effectiveness of dynamic assessment (DA) in revealing outcomes of cognitive education programmes. Three programmes based on "mediated learning experience" theory are reviewed: "Feuerstein's Instrumental Enrichment", "Bright Start", and "Peer Mediation with…

This dissertation comprises three papers that propose, discuss, and illustrate models to make improved inferences about research questions regarding student achievement in education. Addressing the types of questions common in educational research today requires three different "extensions" to traditional educational assessment: (1)…

KIPP (Knowledge is Power Program) is a national network of public charter schools whose stated mission is to help underserved students enroll in and graduate from college. Prior studies (see Tuttle et al. 2013) have consistently found that attending a KIPP middle school positively affects student achievement, but few have addressed longer-term…

Evidence from Project STAR has suggested a considerable advantage of being in small classes in early grades. However, the extra benefits of additional years in small classes have not been discussed in detail. The present study examined the additional effects of being in small classes for more than 1 year. We find that once previous grade…

"Characteristics of Excellence in Undergraduate Research" ("COEUR") is based on the collective experience, over many years, of Council on Undergraduate Research members who have engaged undergraduate students in research, developed undergraduate research programs, mentored new faculty to include undergraduate research in their…

An effect size of about 0.70 (or 0.40-0.70) is often claimed for the efficacy of formative assessment, but is not supported by the existing research base. More than 300 studies that appeared to address the efficacy of formative assessment in grades K-12 were reviewed. Many of the studies had severely flawed research designs yielding…

This paper examined whether year round schooling (YRS) in California had an effect upon the outcome and growth of schools' Academic Performance Index (API) scores. While many previous studies had examined the connection between YRS and academic achievement, most had lacked the statistical rigour required to provide reliable interpretations. As a…
