Establishing validated science programs for students with or at risk for learning disabilities requires testing treatment effects and exploring differential response patterns. This study explored whether students' initial mathematics and reading skills influenced their treatment response to a whole-class, second-grade science program called…

Recent evidence points to the early elementary grades as a pivotal point for the development of science learning trajectories and achievement gaps. Using data from the Early Childhood Longitudinal Study, this study estimates the degree to which time spent on science and the breadth of science topics/skills covered predict science achievement in…

This study, which was reviewed through the Registered Report process, examined the initial efficacy of the Scientific Explorers program (Sci2) on second-grade students' science achievement. Sci2 is grounded in the growing body of empirical research on science instruction, embedding principles of explicit instruction within a guided inquiry-based…

This study explores the importance of scientific observation in primary education, highlighting how the use of observation sheets can facilitate the acquisition of knowledge and the development of students' observation skills. In the research, 153 second-grade students were divided into three experimental groups, each group observing a woody plant…

Following a theoretical framework that recognizes the potential of promotive and inhibitive effects on children's development, this study explored child-, family-, classroom-, and school-level factors as predictors of Latinx (N = 4,590) students' early elementary science achievement. Research Findings: Employing a path modeling approach with…

Nothing satisfies a teacher more than seeing a smile of delight on students' faces when they turn over their test paper to reveal a successful score. In today's world of standardized testing, some elementary science teachers may struggle to help students move from active engagement in hands-on science experiences to high levels of…

School closures because of natural phenomena, such as COVID-19, underscore the importance of effective distance learning strategies when there are no in-school alternatives. Our study describes the implementation of a multimedia science program before and after school closure due to COVID-19 in a variety of ways depending on schools'…

The purpose of this study was to examine whether possible relationships might exist between the quality of reform-based science instruction and science and reading achievement in second grade. The study also examined separately possible interactions between quality of instruction and gender and race. The study involved an analysis of data…

Project Clarion, a Jacob K. Javits-funded project, focused on the scale-up of primary-grade science curricula. Curriculum units, based on an Integrated Curriculum Model (ICM), were developed for high-ability learners, but tried out with all students in Title I settings to study the efficacy of the units with all learners. The units focus on the…

In this year-long randomized control trial (RCT), we evaluated the effectiveness of a year-long, intensive, and structured virtual professional development (VPD) accompanying science-integrated English-as-second-language (ESL) instructional intervention on 187 second grade English learners' English language and literacy development in suburban…

English language learners (ELLs) bring a wealth of knowledge to science classrooms, yet often that knowledge is untapped by traditional instruction and assessment. As classrooms become increasingly diverse, it is critical to recognize the depth of understandings ELLs bring to classrooms to explain the scientific world around them. English language…

Science IDEAS is an evidence-based model that reflects interdisciplinary research findings that support the integration of literacy (e.g., reading comprehension) within science instruction in grades K-5. Presented is a framework for planning integrated science and literacy instruction in which six elements (hands-on investigations, reading,…

This study focused on accelerating development of science knowledge and understanding at the primary level (grades 1-2) as a means for enhancing reading comprehension (i.e. early literacy). An adaptation of a grade 3-5 cognitive-science-based, instructional model ("Science IDEAS") that integrated science with reading and writing, this…

The purpose of the study was to measure the effects of higher level, inquiry-based science curricula on students at primary level in Title I schools. Approximately 3,300 K-3 students from six schools were assigned to experimental or control classes (N = 115 total) on a random basis according to class. Experimental students were exposed to…

This mixed methods case study examined the implementation of a 1:1 iPad initiative in a suburban, co-educational, independent, preK-4th grade elementary school in the United States. This article focuses on how teachers used iPads to differentiate instruction and across multiple content areas. Findings show the processes by which teachers employed…
