Many chemistry laboratory exercises follow a given protocol with known results. Such traditional laboratories rarely give students an accurate representation of how research is conducted, the scientific practices involved in research, and the ownership that accompanies developing and carrying out an independent project. Several laboratory reforms…

This article aims to investigate how science teachers engaged with the macroscopic, sub-microscopic and symbolic levels of representations in their Chemistry teaching. Data were collected in Limpopo province in South Africa from 15 "lead" teachers and this paper reports on five lessons presented by the teachers during professional…

The effect of intervention activities on the chemistry content knowledge of 92 preservice chemistry teachers (PSCT) was examined via a pre and post true/false with confidence level test focusing on ionisation energy values and the use of a common alternative conception (AC). Data were collected from three cohorts of PSCT each engaged in a one year…

"Mythbusters: The Explosive Exhibition" is a traveling exhibit based on the popular television show. When housed at the Museum of Science and Industry, Chicago, it included a traditional, interactive free flow exhibition space followed by a live facilitated show. This paper describes results from an experimental study about the effects…

Darwinian evolution is difficult to understand because of conceptual barriers stemming from intuitive ideas. This study examined understanding of evolution in 52 students (M = 14.48 years, SD = 0.89) before and after a guided field trip to a natural history museum and in a comparison group of 18 students (M = 14.17 years, SD = 0.79) who did not…

The acquisition of everyday scientific concepts by 3-6-year-old children attending early childhood institutions has been widely studied. In contrast, research on science learning processes among younger children is less extensive. This paper reports on findings from an exploratory empirical study undertaken in a "stay and play" service…

Scientific modelling is a key practice in which K-12 students should engage to begin developing robust conceptual understanding of natural systems, including water. However, little past research has explored primary students' learning about groundwater, engagement in scientific modelling, and/or the ways in which teachers conceptualise and…

Background: Enhancing students' metacognitive abilities will help to facilitate their understanding of science concepts. Purpose: The study was designed to conduct and evaluate the effectiveness of a repertoire of interventions aimed at enhancing secondary school students' metacognitive capabilities and their achievements in science. Sample: A…

This article describes a research study on the connection of Cultural Historical Activity Theory (CHAT) with Science Education in the early grades. The research study took place in the University of Ioannina, Greece with the support of the @fise research group. Within this frame, a narrative about light, colors and shadows was written as part of…

As widespread as Science, Technology, Engineering, and Math (STEM) initiatives and reforms are today in education, a rudimentary problem with these endeavors is being overlooked. In general, education programs and school districts are failing to ensure that elementary teachers who provide children's early academic experiences have the appropriate…

Background: Scientific literacy development is widely emphasized as the overarching goal of science education. It encompasses development of understanding of the nature of science as well as knowledge, attitudes, and values that contribute to empowering adolescents to engage with and make evidence-based decisions about socioscientific issues.…

The understanding of core concepts and processes of science in solving problems is important to successful learning in biology. We have designed and developed a Web-based, self-directed tutorial program, "SOLVEIT," that provides various scaffolds (e.g., prompts, expert models, visual guidance) to help college students enhance their…

Open-ended interviews were used to study differences in Grade 7-8 teachers' beliefs about exemplary classroom practices produced by exposure to in-service professional development programs based on different theoretical frameworks. Teachers who had participated in an intensive, inquiry-based, in-service professional development program that…

Eighteen middle and high school students with visual impairments participated in a weeklong field-based geology summer camp. This paper reports the curriculum, strategies, and what the students learned about Earth science by climbing in and out of caves, collecting fossils, exploring a bog, and interacting with experts in the field. Students were…
