We evaluated the effectiveness of two alternative middle-school science curriculum sequences, namely, a general science model and a topic-specific model (i.e., physics, chemistry, etc.). We also investigated the differential effectiveness of the alternative sequences for two ethnic groups. The sample consisted of 367 grade 8 science students from…

Given the dearth of high-quality curriculum materials aligned with the new standards (NGSS and CCSS) and low student persistence in STEM fields, we sought to develop and test a STEM curriculum that would improve student knowledge, interest, and emotions. A cluster randomized control trial was conducted to assess the impact of Speedometry, a…

The overall goal of the present study was to develop, implement, and test the effectiveness of a curriculum designed to improve spatial thinking amongst preschool children. Specifically, the study explored the effects of shape-based training on 4-year-old children's ability to disembed and whether the training transferred to improvement in mental…

Many educational Randomized Controlled Trials (RCTs) collect baseline versions of outcome measures (pretests) to be used in the estimation of impacts at posttest. Although pretest measures are not necessary for unbiased impact estimates in well executed experimental studies, using them increases the precision of impact estimates and reduces sample…

A tobacco use prevention curriculum tailored for deaf/hard of hearing youth was tested using a quasi-experimental design. Two schools for the deaf received the curriculum; two served as noncurriculum controls. Surveys assessed changes in tobacco use, tobacco education exposure, and tobacco-related attitudes and knowledge among students in grades…

How can children's natural perceptuo-motor skills be harnessed for teaching and learning mathematical structure? We address this question in the case of the integers. Existing research suggests that adult mental representations of integers recruit perceptuo-motor functionalities involving symmetry. Building on these findings, we designed a…

Background: Evaluations of substance use screening and brief intervention (SBI) curricula typically focus on learner attitudes and knowledge, although effects on clinical skills are of greater interest and utility. Moreover, these curricula often require large amounts of training time and teaching resources. This study examined whether a 3-hour…

There is a national need for effective interventions to improve school readiness and subsequent achievement in mathematics for students from low-income families. The purpose of this study was to implement and evaluate a 2-year preschool math intervention that began at preschool entry when children were 3 years of age and continued through the end…

As societal challenges involving sustainable development increase, the need to effectively integrate this inherently multidisciplinary topic into existing curricula becomes more pressing. Multidisciplinary, team-taught, project-based instruction has shown effectiveness in teaching teamwork, communication, and life-long learning skills, and…

There has been a growing concern about how best to address the needs of dual language learners with language impairments. Most dual language programmes have been evaluated with children with typical language development (TLD) and as a result, very little is known about the effect of these programmes on children with language disabilities. The…

Disadvantaged children--those in poverty, minorities, or whose first language is not English--often come to kindergarten several years behind their more advantaged peers, especially in the areas of literacy and oral language development. A logical place to begin making a difference in children's literate lives is in the years before kindergarten.…

P.E. classes are often the only opportunity for inner-city youth to engage in physical activity, but budget cuts and pressure to perform well on standardized tests has made P.E. an afterthought for many school administrators. This study evaluated the effectiveness of a new P.E. curriculum in five Los Angeles inner-city schools. Interviews were…

This study examines whether the Problem Based Economics curriculum developed by the Buck Institute for Education improves grade 12 students' content knowledge as measured by the Test of Economic Literacy, a test refined by the National Council on Economic Education (NCEE) over decades. Students' problem-solving skills in economics were also…

Several pressing issues call for institutions charged with the responsibility to educate prospective teachers to rethink their model of teacher preparation to better address the educational needs of English Language Learners (ELLs). It is projected that by 2025 one in four students in the U.S. will be from homes where a language other than English…

Purpose: The first purpose of this study was to determine the extent to which students in university capstone public relations classes who receive teamwork training demonstrate effective team behaviors, produce quality work, experience satisfaction in the teamwork process, and engender client satisfaction. The second purpose was to determine the…
