Research into early childhood children's understandings in science has a long history. However, few studies have drawn upon cultural-historical theory to frame their research. Mostly, what is known has come from studies which have examined individual understandings of science concepts, without reference to culture, context or the collective nature…

The Next-Generation Science Standards (NGSS) challenge primary teachers and students to work and think like scientists and engineers as they strive to understand complex concepts. Teachers and teacher educators can leverage what is already known about inquiry teaching as they plan instruction to help students meet the new standards. This…

In this self-study, two science educators partnered with two elementary teachers to plan, implement, and reflect on a unit taught in second grade classrooms that integrated science and language arts. The researchers hoped to increase their pedagogical content knowledge (PCK) for elementary science teaching so that they might use their experiences…

The purpose of this research was to explore children's understandings of everyday, synthetic and scientific concepts to enable a description of how abstract, verbally taught material relates to previous experience-based knowledge and the consistency of understanding about cloud formation. This study examined the conceptual understandings of cloud…

The purpose of this study was to investigate the various roles that early elementary teachers adopt when questioning, to scaffold dialogic interaction and students' cognitive responses for argumentative practices over time. Teacher questioning is a pivotal contributing factor that shapes the role teachers play in promoting dialogic interaction in…

Inquiry- and context-based teaching strategies have been proven to stimulate and motivate students' interests in learning science. In this study, 12 teachers reflected on these strategies after using them in primary schools. The teachers participated in a continuous professional development (CPD) programme. During the programme, they were also…

"MyScience" is a primary science education initiative in which being in a community of practice is integral to the learning process. In this initiative, stakeholder groups--primary teachers, primary students and mentors--interact around the "domain" of "investigating scientifically". This paper builds on three earlier…

This paper begins with the view that the generation of meaning is a multimodal process. Props, drawings, graphs, gestures, as well as speech and written text are all mediators through which students construct new knowledge. Each semiotic context makes a unique contribution to the conceptualization of scientific entities. The human body, in…

Energy is considered both a core idea and a crosscutting concept in science education. A thorough understanding of the energy concept is thought to help students learn about other (related) concepts within and across science subjects, thereby fostering scientific literacy. This study investigates students' progression in understanding the energy…

The main purpose of this study was to explore the factors mediating the translation of second grade teachers' nature of science (NOS) views into classroom practice after completing a graduate level NOS course. Four second grade in-service elementary teachers comprised the sample of this study. Data were collected from several sources during the…
