LXD Research conducted a study to evaluate the impact of the Zaner-Bloser Kickstart: Number Sense program, a math intervention designed to enhance foundational math skills among first and second-grade students in an Oregon school district over a three-year period from spring 2019 to Spring 2023. The program was implemented in two schools, engaging…

Early mathematics achievement sets the stage for a range of important academic and career outcomes. As efforts to improve elementary mathematics instruction have increased, efforts to better understand how students develop mathematics knowledge and why students respond to mathematics instruction have also emerged. Given known correlations between…

Oregon's Effective Behavioral and Instructional Support Systems (EBISS) initiative was implemented in 25 school districts. The initiative trained and coached district leaders and teachers in the use of the EBISS model through the lens of implementation science. The EBISS model integrates school-wide positive behavior intervention and supports…

This study examined the role of initial skill in moderating intervention effects of a 50 lesson mathematics intervention program, ROOTS, for at risk kindergarten students focused on developing whole number concepts and skills. The study utilized a randomized block design with at-risk students (n = 592) within classrooms (n = 60) randomly assigned…

This paper reports the results of a randomized controlled trial evaluating "We Have Skills," a brief curriculum designed to teach early elementary students academic and social skills as well as improve teacher efficacy in classroom management. Intervention efficacy was tested with 127 teachers, randomly assigned to condition, and 2,817…

Early number skills, comprised of both informal and formal skills, are associated with later mathematics achievement. Thus, the development of foundational early number skills is an important aspect of early mathematics instruction. This study explored relations between early number skills gains and mathematics achievement for students at risk for…

There is some evidence that reading and spelling are complementary processes. The purpose of this study was to investigate the extent to which contextualized spelling (i.e., spelling activities within the context of reading instruction) is used to support reading in first-grade core reading programs. Analysis of 75 lessons across five programs…

For the 2014 study, "The Iterative Development and Initial Evaluation of We Have Skills!, an Innovative Approach to Teaching Social Skills to Elementary Students", researchers examined the effects of We Have Skills! (WHS), a supplemental, video-based social skills program for early elementary students. WHS consists of three components:…

"Investigations in Number, Data, and Space"[R], published by Pearson Scott Foresman, is an activity-based K-5 mathematics curriculum designed to help students understand number and operations, geometry, data, measurement, and early algebra. Each instructional unit focuses on a particular content area and lasts from two to five-and-a-half…

Well-designed mathematics instruction focused on concepts and problem-solving skills associated with measurement and data analysis can build a foundational understanding for more advanced mathematics. This study investigated the efficacy of the Precision Mathematics Level 1 (PM-L1) intervention, a Tier 2 print- and technology-based mathematics…

Widespread concern has been expressed about the persistent low mathematics achievement of students in the US, particularly for students from low-income and minority backgrounds and students with disabilities. Instructional gaming technology, when designed and fictionalized well, has the potential to improve the motivation and mathematics…

We report on a practitioner implementation of Fusion, a first-grade mathematics intervention. Studies such as this evaluation of a loose implementation under realistic conditions are important to curriculum developers' understanding of how evidence-based programs and tools work under a variety of implementation scenarios. In this…
