Science controversy has the potential to reinforce students' understanding of important biological concepts as well as helping students forge connections between concepts they may have previously seen disparate. Science controversy has the potential to help students make cross-disciplinary connections and therefore it should become an integral…

An activity to promote student understanding of the nature of science as a method of inquiry by engaging students in a real-life experience that requires them to utilize their critical thinking skills is designed. The activity links scientific concepts to the real world experiences of students and increase the relevancy of the content.

The aim of this article is to examine how drama and theatre activities may enhance learning in science education, by creating a learning situation that is significant in the lives of students. The author offers a structured survey of different science and drama projects, together with theoretical reflections on the use of drama in science…

Physicists have known for some time that pendulum motion is a useful analogy for other physical processes. Chemists have played with the idea from time to time but the strength of the analogy between pendulum motion and chemical processes has only received prominent published recognition since about 1980, although there are details of the analogy…

The implications of history and philosophy of chemistry are explored in the context of chemical models. Models and modeling provide the context through which epistemological aspects of chemistry can be promoted. In this work, the development of ideas and models about acids and bases (with emphasis on the Arrhenius, the Bronsted-Lowry, and the…

The crisis in physics education necessitates searching for new relevant meanings of physics knowledge. This paper advocates regarding physics as the dialogue among discipline-cultures, rather than as a cluster of disciplines to be an appropriate subject of science education. In a discipline-culture one can distinguish elements of knowledge as…

This study aims to analyse, based on common characteristics of the Nature of Science, how first year university Physics textbooks present the introduction of the concept and theories of magnetic field. It shows that despite the increasing number of studies into the Nature of Science in Science Education, Physics textbooks fail to adopt the results…

Einstein, who had already developed the light-quantum theory, knew the inadequacy of Maxwell's theory in the microscopic sphere. Therefore, in writing his paper on special relativity, he had to set up the light-velocity postulate independently of the relativity postulate in order to make the electromagnetic foundation of physics compatible with…

Ignoring the role of chance in science distorts the nature of the scientific process. Teachers can address this issue by means of several in-depth historical case studies, such as the discovery of electromagnetism by Oersted. Oersted was led to his lecture experiment by logic (two new hypotheses), but its success from the first trial was largely…

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…

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…
