QCA specified that science should include "How Science Works" at Key Stage 4 (age 14-16) from 2006. Since then, different "versions" have been specified for inclusion from primary through to A-Level (Orrow-Whiting et al, 2007). HSW seems to act as an umbrella term for part of the curriculum that "focuses on the evidence to…

We examine the respective roles of substantive understanding (i.e., understanding of factual knowledge, concepts, laws and theories) and procedural understanding (an understanding of ideas about evidence; concepts such as reliability and validity, measurement and calibration, data collection, measurement error, the ability to interpret evidence…

This study reports the results of the first systematic investigation into Astro 101 students' conceptual and reasoning difficulties with cosmology. We developed four surveys with which we measured students' conceptual knowledge of the Big Bang, the expansion and evolution of the universe, and the evidence for dark matter. Our classical test theory…

Students' scientific investigations have been identified in national standards and related reform documents as a critical component of students' learning experiences in school, yet it is not easy to implement them in science classrooms. Could science demonstrations help science teachers put this recommendation into practice? While demonstrations…

Objective: Changes in reward-related behavior are an important component of normal adolescent affective development. Understanding the neural underpinnings of these normative changes creates a foundation for investigating adolescence as a period of vulnerability to affective disorders, substance use disorders, and health problems. Studies of…

While it is important to nurture creativity in young children, it is popularly associated more with the arts than the sciences. This paper reports on a series of studies designed to explore teachers' conceptions of creative thinking in primary school science. Study #1 examines pre-service primary teachers' ideas of what constitutes creativity in…

The purpose of this research is to compare students' perceptions of the learning environment in a traditional science classroom and a field study classroom. This mixed methods study used a sequential explanatory design. Phase one was the quantitative phase using two survey tools. A modified version of the "What is happening in this Classroom…

As part of becoming scientifically literate, students should come to appreciate epistemic aspects of science. Little research has been conducted on elementary students' epistemological beliefs specific to science education. This study offers insights into third-grade students' epistemological beliefs while paying attention to the intersection of…

"If someone were traveling to our area for the first time during this time of year, what would you tell them to bring to wear? Why?" This question was used to engage students in a guided-inquiry unit about how climate differs from weather. In this lesson, students explored local and national data sets to give "travelers" advice…

The need for additional nursing and health care professionals is expected to increase dramatically over the next 20 years. With this in mind, students must have strong biomedical science knowledge to be competent in their field. Some studies have shown that participation in bioscience laboratories can enhance science knowledge. If this is true, an…

The context and nature of teacher efficacy beliefs provide a method upon which to explore science teachers' perceptions of their teaching effectiveness and student achievement as a function of ethnicity. Promotion of a more in-depth knowledge of science teaching efficacy requires cross-sectional and longitudinal investigations. In this study, a…

This study examines first graders' epistemic reasoning, in tacit "practical epistemologies" reflected in thinking about an investigation of their own design. I analyzed children's epistemic reasoning, following a design experiment scaffolding increasing regulation of scientific inquiry in a domain they studied in depth. Participants…

Nanoscale science and engineering are disciplines that examine the unique behaviors and properties of materials that emerge at the size range of 1 to 100 nanometers (a billionth of a meter). Nanobiotechnology is a sub-discipline of nanoscience that has arisen more recently. Nanobiotechnology is already impacting the fields of healthcare and…

Student-directed, open-ended scientific investigations and invention projects may serve to deepen and broaden students' scientific and technological literacy, and, in so doing, enable them to succeed in democracies greatly affected by processes and products of science and technology. Science fairs, events at which student-led projects are…

"The Wheel of Scientific Investigation and Reasoning" (Kramer 1987; Paul and Binker 1992) is a graphic representation of the scientific investigative process. The scientific process is depicted in a wheel rather than in a list because "the process of scientific inquiry can begin from any stage, and that stage may be revisited as often as the…
