This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program to improve elementary students' vocabulary skills and reading comprehension. The study used a multi-site cluster randomized, experimental design, which randomly assigned 92 4th grade classrooms (n=2558 students) from two cohorts to a treatment or control…

We conducted a process evaluation of the Shaping Healthy Choices Program, a multicomponent school-based nutrition program, when implemented in partnership with University of California (UC) CalFresh and UC Cooperative Extension (UCCE). There were positive impacts on participating students, but results varied across counties, possibly due to…

Background: Few nutrition interventions in kindergarten classes have been evaluated, and none has been tested for program effectiveness, implementation, and dissemination. Building a Healthy Me (BHM) is a nutrition intervention for kindergarteners that is classroom-based and includes a family component. This study evaluated the public health…

Numerous classroom-based interventions have aimed to improve sexual health outcomes for young people, yet few have shown strong, lasting effects. Ecological approaches that address multiple levels of a young person's environment offer largely untapped potential to positively change sexual behaviour. This paper presents results of a…

This article reports on the effectiveness of First Step to Success, a secondary-level intervention appropriate for students in early elementary school who experience moderate to severe behavior problems and are at risk for academic failure. The authors demonstrate the intervention's short-term effects on multiple behavioral and academic outcomes…

Improving bio-security practices among 4-H members who raise and show project animals is important. Bio-security measures can reduce the risk of disease spread and mitigate potential health and economic risks of disease outbreaks involving animal and zoonotic pathogens. Survey data provided statistical evidence that the Bio-Security Proficiencies…

This work highlights a heuristic model for professional learning while examining the implementation of a reform initiative. The researchers used longitudinal data collected from surveys to develop and fit a model of professional learning where patterns of interaction among teachers changed the discussion about English learner instruction. Data…

The purpose of this study was to evaluate the impact of Achieve3000, a differentiated online literacy curriculum, on students' scores on the California State Test (CST). In the 2011-12 school year, 1,957 students in Chula Vista began using Achieve3000's solutions in 3rd through 8th grade. Using a form of propensity score matching called Inverse…

This article reports on two studies using "Language Muse[superscript SM]" (LM), a web-based, teacher professional development (TPD) application designed to enhance teachers' linguistic awareness and to support teachers in the development of language-based instructional scaffolding for English language learners (ELL). In Study 1,…

The Developmental Strategies for College Readiness and Success Resource Guide was produced by the Education Commission of the States and the Southern Regional Education Board for the "Countdown to 2015: Developmental Strategies to Advance Readiness in the Common Core Era" convening held April 21-23, 2014 in Charlotte, North Carolina. The…

English as a Second Language (ESL) learners' access and achievement in Algebra I was examined to determine whether ESL students continue to be denied equal opportunity-to-learn (OTL) as a result of unnecessary tracking practices. In this quasi-experiment, a pre-post retrospective comparison group design was used to determine the effects of the…

The nature and role of developmental education classes are under tremendous scrutiny across the nation today. Specifically, students are entering community college and four-year institutions of higher education unprepared to understand and apply much of the reading material presented to them in college-level classes. This article describes the…

Teaching entrepreneurship--how to create, grow and run a business or organization--is one potential means to increase college and career readiness skills. Learning how to start a business can improve critical thinking, communication and collaboration (Gallagher, Stepien, & Rosenthal, 1992; Hmelo, 1998), which are key qualities for academic as…

This article describes an outreach program to broaden participation in computing to include more students with visual impairments. The precollege workshops target students in grades 7-12 and engage students with robotics programming. The use of robotics at the precollege level has become popular in part due to the availability of Lego Mindstorm…

Most K-12 evaluations are designed to make inferences about how a program implemented at the classroom or school level affects student learning outcomes and such inferences inherently involve hierarchical data structure. One methodological challenge for evaluators is linking program implementation factors typically measured at the classroom or…
