This paper reports a study on teachers' domain-specific beliefs about the chemistry curriculum for upper-secondary education in The Netherlands. Teachers' beliefs were investigated using a questionnaire focused on the goals of the chemistry curriculum. The design of the questionnaire was based on three curriculum emphases: "fundamental…

The purpose of this study was to explore the relationship of learner characteristics and preservice teachers' views of nature of science (NOS) prior to formal instruction. Learner characteristics investigated included metacognitive awareness, self-efficacy, attitudes toward science teaching, Perry's intellectual and ethical developmental levels,…

In this essay, Clayton Pierce examines the epistemological standpoints of Intelligent Design (ID) and evolutionary science education, focusing specifically on the pedagogical question of how ID and modern science-based education fail to promote democratic relations in how students learn, think, and associate with science and technology in society.…

"How ScienceWorks" is now the focus of the national science specifications in English schools. This article is a brief introduction to the philosophy of science from the Greeks to the present day that underpins this notion. It consists of a brief summary of the contributions of nine philosophers and/or scientists to the debate: Aristotle, Roger…

With the rapid progress of modern civilization, creativity and innovation within a techno-economic perspective are becoming the major driving forces behind the sustainability of economic growth and competitive achievements. The current paper will focus on developing a clear concept of the terms creativity and innovation, and investigate their…

Empirical correlations are a practical means of providing approximate answers to problems in physics whose exact solution is otherwise difficult to obtain. The correlations relate quantities that are deemed to be important in the physical situation to which they apply, and can be derived from experimental data by means of dimensional and/or scale…

A hands-on project was developed to educate new chemical engineering students about the types of problems chemical engineers solve and to improve student enthusiasm for studying chemical engineering. In this project, students studied the phenomenon of carbonated beverages going flat. The project was implemented in 2003 and 2004 at Kansas State…

This study explored relationships between preservice early childhood teachers' views of nature of science (NOS), cognitive developmental levels, and their cultural values. Using the Views of Nature of Science Questionnaire (VNOS-B) and interviews, we assessed views of NOS. The Learning Context Questionnaire (LCQ) was used to determine the…

The reading of science-related, historical nonfiction alone does not necessarily lead students to make personal connections to science or understand science as a human endeavor interdependent with culture, society, and history. Teachers must structure students' reading to ensure that they consider specific aspects of science while reading and…

I report on benefits from 26 teacher-participant evaluators of a computer game designed to motivate learning and to ease conceptual understanding of biology in South Africa. Using a developmental, social constructivist and interpretative model, the recommendation is to include the value systems and needs of end-users (through social dialogue);…

This study investigated whether or not an increase in secondary science teacher knowledge about evolution and the nature of science gained from completing a graduate-level evolution course was associated with greater preference for the teaching of evolution in schools. Forty-four precertified secondary biology teachers participated in a 14-week…

This article explains a simple way to demonstrate natural convection, such as from a lit candle, in the classroom using an overhead projector. The demonstration is based on the principle of schlieren imaging, commonly used to visualize variations in density for gas flows.

Everyone who teaches physics knows very well that sometimes a simple device or experiment can help to make a concept clear. In this paper, inspired by "The Jumping Pencil" by Martin Gardner, I will discuss a simple demonstration device that can be used to start the study of air pressure.

Although one role of computers in science education is to help students learn specific science concepts, computers are especially intriguing as a vehicle for fostering the development of epistemological knowledge about the nature of scientific knowledge--what it means to "know" in a scientific sense (diSessa, 1985). In this vein, the…

Classroom experiments on atmospheric pressure focus largely on demonstrating its existence, often in a most impressive way. A series of amusing physics demonstrations is widely known and practiced by educators teaching the topic. However, measuring the value of atmospheric pressure(P[subscript atm]) is generally done in a rather mundane way,…
