This mixed-methods study aimed to investigate the effectiveness of the technology-embedded scientific inquiry (TESI) model on teachers' and students' scientific inquiry abilities and digital learning technologies fluency to enhance science education learning outcomes. The TESI framework guided the construction and execution of this study. The…

Integrating Course-based Undergraduate Research Experiences (CUREs) into introductory STEM courses at the university level has been recognized as important in increasing persistence in STEM. A significant area of attrition from the STEM pathway, however, occurs during secondary school when student interest in STEM rapidly declines. In this study,…

Students attending schools in poor and historically marginalized communities lack access to curricula that combines both relevant science content and investigative practices--components the National Research Council (2012) has identified as necessary for effective learning. This lack of curricular access is also problematic in that it: (1)…

The present study examines instructional approaches and cognitive factors involved in elementary school children's thinking and learning the Control of Variables Strategy (CVS), a critical aspect of scientific reasoning. Previous research has identified several features related to effective instruction of CVS, including using a guided learning…

The purpose of this quasi-experimental, nonequivalent pretest-posttest control group design study was to determine if any differences existed in upper elementary school students' science academic achievement when instructed using an 8-week integrated science and English language arts literacy supplemental instructional intervention in conjunction…

This study investigated the effects of two instructional approaches -- Discovery Learning Scientific Community Laboratories (DL-SCL; Treatment) and non-DLSCL laboratories (Control) -- on students' conceptual understanding, epistemological views, and academic achievement in a Physics-1 lab. Conceptual understanding was measured pre/post using the…

This experimental investigation evaluated the impact of educational songs on a child's ability to recall scientific content from an educational television program. Preschoolers' comprehension of the educational content was examined by measuring children's ability to recall the featured science content (the function of a pulley and…

The purpose of this study was to introduce an instructional technique for teaching complex tasks in physics, test its effectiveness and efficiency, and understand cognitive processes taking place in learners' minds while they are exposed to this technique. The study was based primarily on cognitive load theory (CLT). CLT determines the amount of…

For decades science educators and educational institutions have been concerned with the status of science content being taught in K-12 schools and the delivery of the content. Thus, educational reformers in the United States continue to strive to solve the problem on how to best teach science for optimal success in learning. The constructivist…

The aim of the study is to investigate the impact of cooperative learning instruction, specifically by using the Jigsaw instructional strategy on science achievement and attitudes towards science among 11th grade students. Based upon previous research literature, it was hypothesized that significant differences existed on gains between general…

This study examined the differences and patterns for three categories between an argument-based inquiry group and a traditional group over the period of the SWH (Science Writing Heuristic) project: (1) teacher talk time, (2) structure of questions (question types), and (3) student responses. The participating teachers were chosen randomly by a…

The purpose of this study was to determine the impact of learning various types of words in biology on students' reading comprehension, vocabulary performance, and science content knowledge. The study involved 315 ninth grade biology students who were placed in one of four groups and spent two weeks for ten minutes per day working on independent…

This study examines the effects of online collaborative learning on middle school students' science literacy and sense of community. A quantitative, quasi-experimental pretest/posttest control group design was used. Following IRB approval and district superintendent approval, students at a public middle school in central Virginia completed a…

This quantitative study involved 157 students in two sections of an undergraduate class in general biology, as well as one instructor who taught both sections of the course. It used resources from the Center for Applied Special Technologies (CAST) to evaluate the viability of a Learning Management System (LMS) to provide Universal Design for…

The purpose of this study was to determine the extent to which sustained teacher professional development in science education affects the classroom instruction of elementary school teachers in third through sixth grade over a 3-year period. The teachers in the study were all elementary endorsed and prepared to be generalists in the content areas.…
