A significant body of scholarship in Physics Education Research (PER) has documented that students have intuitive knowledge resources that they use to make sense of the physical world. Similarly, for physicists, symmetry is fundamental to making sense of the universe. In this dissertation, I explore students' intuitive resources related to…

In this position paper, we introduce the concept of socioscientific capital (SSC) to denote students' resources that unequivocally play a part when students learn about and make decisions regarding socioscientific issues (SSIs). Students use a variety of resources when they engage with SSI. Our conceptualization of SSC expands on current…

This study explored what challenges teachers experienced when integrating indigenous knowledge systems (IKS), which are culture specific, into practical work in natural sciences classrooms with diverse learners. Using an exploratory qualitative case study based on an interpretive paradigm, three natural sciences teachers and two subject advisors…

Recently, much importance has been placed on early science education. This study examined the associations between kindergarten teachers' science teaching self-efficacy, outcome expectations, and their integration of science into teaching, and investigated how four potential factors (i.e. mastery experience, interpersonal support, previous science…

In addition to traditional sources, includes experiments, computer models and simulations, and films. (MLH)

Discusses problems facing the world with increasing demands for food, energy, raw materials and goods, and at the same time confronted with a population explosion. Views the future of the United States optimistically when compared to less developed countries. (JR)

Looks at the potential of wood as a chemical raw material to replace the dwindling supplies of fossil fuels as a source of hydorcarbons and, to a lesser degree, of energy. (GA)

Assesses the current energy problems and considers possible solutions. (MDR)

The use of ICT in the classroom is very important for providing opportunities for students to learn to operate in an information age. Studying the obstacles to the use of ICT in education may assist educators to overcome these barriers and become successful technology adopters in the future. This paper provides a meta-analysis of the relevant…

It is argued that immediate steps need to be taken in order to buy time until new, clean power sources become available. (DF)

The National Health Planning and Resources Development Act of 1974, P. L. 93-641, provides for a broad spectrum of agencies, directives and resources for the planning and development of health services, including protective as well as health care services. These provisions are delineated here. (BB)

Consists of excerpts from a forthcoming publication of the United States Environmental Protection Agency, Student's Guide to Solid-Waste Management.'' Discusses the sources of wastes from farms, mines, factories, and communities, the job of governments, ways to collect trash, methods of disposal, processing, and suggests possible student action.…

Explains using exponential mathematics, the effect of growth on rate of consuming energy resources. Concludes that we are running out of energy resources at a greater rate than many people think. Lists few options left such as conservation by stopping growth of consumption, recycling, and research to develop alternate sources. (GA)
