When identifying instruments that have had great influence on the history of physics, none comes to mind more quickly than the pendulum. Though first treated scientifically by Galileo in the 16th century, and in some respects nearly "dead" by the middle of the 20th century; the pendulum experienced "rebirth" by becoming an archetype of chaos. With…

The simple pendulum is a model for the linear oscillator. The usual mathematical treatment of the problem begins with a differential equation that one solves with the techniques of the differential calculus, a formal process that tends to obscure the physics. In this paper we begin with a kinematic description of the motion obtained by experiment…

The author describes his program of research over the past 25 years. This research falls into 6 areas that are interdependent and that inform each other. The overall program is guided by 3 bioecological principles that posit the need for proximal processes and motivation to actualize biological potential. The author presents examples of…

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…

We describe a longitudinal study of a secondary education biology teacher at two moments in her career (1993-2002), determining the changes in her conceptions of the nature of science and its teaching and learning, and the factors that favored or hindered such changes. The changes were analyzed using cognitive maps, constructed on the basis of the…

This study investigates how high school students respond to an environment of authentic science inquiry while participating in an intensive summer institute, the Waksman Student Scholars Programme at Rutgers University. We examined how students apprenticed with expert scientists in a study of contemporary questions in molecular genetics. Students…

Despite increased appreciation of the role of "proof" in students' mathematical experiences across "all" grades, little research has focused on the issue of understanding and characterizing the notion of proof at the elementary school level. This paper takes a step toward addressing this limitation, by examining the characteristics of four major…
