A vast majority of elementary students struggle with the core, pre-algebraic concept of mathematical equivalence. The Improving Children's Understanding of Equivalence (ICUE) intervention integrates four research-based strategies to improve outcomes for second grade students: (1) introducing the equal sign before arithmetic, (2) non-traditional…

For nearly four decades, research has documented positive correlations between metacognitive abilities and student growth. Teachers who wish to cultivate metacognitive thinking should encourage their students to plan, investigate, and expand on the concepts they learn in class (Fisher, Frey, & Hattie, 2016; Flavell, 1979). This mixed-methods…

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…

Insufficient physical activity during the elementary school years has been associated with a number of health problems (Strong et al., 2006). During the school day, the recess period provides the greatest opportunity for children to engage in physical activity (Robert Wood Johnson, 2007). Nonetheless, most children spend the majority of their…

The research featured in this paper is part of the CORE-PACE Research Partnership, which is focused on producing research that informs continuous improvement in the CORE districts as well as policy and practice in California and beyond. In this report, the authors used data from multiple interim assessments to examine how the rate of student…

Many math students, both EL and non-EL, struggle to reach the level of proficiency on California state tests which is required since the passage of NCLB in 2002 (California Department of Education, 2012). In California only 34% of students scored at the level of proficiency or above in 2011 (National Assessment for Educational Progress, 2012). The…

Research Findings: Evolution by natural selection is often relegated to the high school curriculum on the assumption that younger students cannot grasp its complexity. We sought to test that assumption by teaching children ages 4-12 (n = 96) a selection-based explanation for biological adaptation and comparing their success to that of adults…

Background: Acute physical activity breaks lasting 10--60 min have been related to positive effects on student focus and academic performance. The aim of this study was to evaluate the impact of repeated brief physical activity-infused academic lessons (1-5 min) on student retention and on-task behavior. Methods: One class from each K-2 grade…

This article reports on a study in which activity theory was used to design, implement, and analyze a 10-week curriculum unit about how honeybees collect nectar with a particular focus on complex systems concepts. Students (n = 42) in a multi-year kindergarten and 1st-grade classroom participated in this study as part of their 10 regular classroom…

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…

Pedagogical competence and teaching efficacy significantly influence the quality of classroom science learning. Without applying pedagogical learning in realistic classroom environments, there is slight possibility that prospective teachers will increase their teaching confidence or develop understanding of how learners acquire and construct…

The study assessed the effectiveness of a pilot intervention to promote the use of eyeglasses in one school in California. The intervention used a one-group pretest, posttest design. Between January and June 2011, during the intervention, all first- and second-grade children received eye evaluations and the children with refractive error received…

As multimedia and technological savvy continue to expand existing notions of contemporary literacy, the need to prepare teachers to use a variety of classroom technologies has never been greater (Author1 & Author2, 2008a; Author1 & Author2, 2009). In order for teachers to be prepared to use such technologies, the structure of teacher…

This article investigates why students reported liking a student-driven learning design better than a highly guided design despite equivalent gains in knowledge assessments in both conditions. We created two learning designs based on the distinction in the literature between student-driven and teacher-led approaches. One teacher assigned each of…

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…
