This study examines the effectiveness of pre-laboratory presentations in an undergraduate general chemistry laboratory using two different modes of delivery: a traditional lecture versus an in-class video presentation. It was anticipated that implementation of videos could result in improved laboratory efficiency, safety, and necessary technical…

This study examined the impact of microteaching experiences of preservice elementary teachers enrolled in a science teaching methods course. The microteaching lessons targeted the physical science concepts represented in the Texas Educational Agency's exam for early childhood through sixth grade teacher certification. The results of this study…

The purpose of this exploratory qualitative study was to investigate prospective elementary teachers' conceptual understanding of buoyancy. Specifically, the study aimed to identify the scientifically accepted conceptions, and misconceptions that preservice teachers hold about buoyancy using an instructional intervention. Presently, there is a gap…

Combined three-dimensional, haptic-enabled, virtual reality (3D HE VR) systems allow students to actively engage and explore various science concepts by leveraging user-friendly and immersive interfaces. Successful implementation of these learning tools in science classrooms hinges upon teachers' perceptions of the technology's potential as a…

Physics and physical science content are essential for many professional fields, and they are an important component of scientific literacy. Yet, students are commonly less engaged in physics learning at all levels. Funds of knowledge approaches to science instruction build upon learners' real-world experiences and interests in order to make…
