Community-based action research (CBAR) encourages students to view internships and other civic-engagement opportunities as the first steps in collaborative projects that build long-term relationships with community partners and model how democracy works. We marshal longitudinal data, qualitative and quantitative, on both attitudes and behaviors to…

This article examines a unique intervention in Chicago Public Schools (CPS) to uncover the causal impact on school performance of an evaluation system based on highly structured classroom observations of teacher practice. An iterative process of observation and conferencing focused on improving lesson planning and preparation, the classroom…

L2 learners' problems with English articles have been linked to learners' L1 and their access to universal semantic features (e.g., definiteness and specificity). Studies suggest that L2 adults rely on their L1 knowledge, while child L2 learners rely more on their access to semantic universals. The present study investigates whether child L2…

This article provides practical guidance for researchers who are designing studies that randomize groups to measure the impacts of educational interventions. The article (a) provides new empirical information about the values of parameters that influence the precision of impact estimates (intraclass correlations and R[superscript 2] values) and…

We developed a web-based tool to provide students with access to old exam problems and solutions. By controlling the order in which students saw the problems, as well as their access to solutions, we obtained data about student learning by studying old exam problems. Our data suggest that in general students learn from doing old exam problems, and…

College students in a psychology research-methods course learned concepts related to inferential statistics and hypothesis decision making. One group received equivalence-based instruction on conditional discriminations that were expected to promote the emergence of many untaught, academically useful abilities (i.e., stimulus equivalence group). A…

During the past decade, the use of standardized benchmark measures to differentiate and individualize instruction for students received renewed attention from educators. Although teachers may use their own assessments (tests, quizzes, homework, problem sets) for monitoring learning, it is challenging for them to equate performance on classroom…

Over the past few decades, service-learning has surged in popularity. Although most programs are implemented in high school and college classrooms, service-learning has the potential for great impact in middle school. The present article evaluates a pilot service-learning program for fifth- and seventh-grade (N = 86) children in a large, urban,…

This guide is designed as a resource for leaders and evaluators of K-12 online learning programs. In this guide, the term "online learning" is used to refer to a range of education programs and resources in the K-12 arena, including distance learning courses offered by universities, private providers, or teachers at other schools;…

Research-based substance use prevention curricula typically yield small effects when implemented by school teachers under real-world conditions. Using a randomized controlled trial, the authors examined whether expert coaching improves the effectiveness of the All Stars prevention curriculum. Although a positive effect on students' cigarette use…

In this set of four supplemental tables, the authors compare the baseline test scores of the treatment and matched control group samples observed in each year after KIPP entry (outcome years 1 to 4). As discussed in Chapter III, the authors used an iterative propensity score estimation procedure to calculate each student's probability of entering…

This study assesses the state of the art of the measurement and use of estimated economic value, or "shadow prices," in applying benefit-cost analysis (BCA) to social program evaluation. It reviews 39 effective social programs whose effects have been evaluated using scientifically rigorous methods and documents outcomes affected by the…

This article presents a control group study of the influence of a partnership-centered, community-based learning program on students' academic writing. The improved writing of first-year students in the Chicago Civic Leadership Certificate Program (CCLCP), we argue, results from the deeply situated learning that took place in the context of…

Social promotion has long been the normal practice in American schools. Critics of this practice, whereby students are promoted to the next grade regardless of academic preparation, have suggested that students would benefit academically if they were made to repeat a grade. Supporters of social promotion claim that retaining students disrupts them…

IT WAS HYPOTHESIZED THAT 91 EXPERIMENTAL SUBJECTS FROM LOW SOCIOECONOMIC STATUS HOMES, PROVIDED WITH A CAREFULLY DESIGNED 2-YEAR VOCATIONALLY ORIENTED EDUCATIONAL PROGRAM AND PREVOCATIONAL DIVISION OF VOCATIONAL REHABILITATION (DVR) COUNSELING, WOULD HAVE SIGNIFICANTLY SUPERIOR ACHIEVEMENT TO THAT OF A MATCHED CONTROL GROUP ENROLLED IN A REGULAR…
