This historical review traces the origins of the Kimball free-cloud model of the chemical bond, otherwise known as the charge-cloud or tangent-sphere model, and the central role it played in attempts to reform the introductory chemical curriculum at both the high school and college levels in the 1960s. It also critically evaluates the limitations…

This paper is about new contents that can be introduced into science education. It is a description of an experience aimed at introducing a complex approach into the final grade of a Brazilian elementary school. The aim is to show the transformation of the conception of space and time from the Middle Ages with the physics of Aristotle to the 20th…

In this article, the author discusses why the history of science should be included in the science curriculum in schools. He also presents some opportunities that can come out of using historical contexts, and findings from a study assessing the place of history of science in readily available textbooks.

The purpose of the study was to identify and refine a conceptual foundation for secondary school engineering education. Specifically, this study sought to address the following research questions: (1) What engineering concepts are present in literature related to the nature and philosophy of engineering?; (2) What engineering concepts are embedded…

Project 2061, begun in 1985, is a long-term effort of scientists and educators on behalf of all children, the purpose of which is to help transform the nation's school system so that all students become well educated in science, mathematics, and technology. Science For All Americans, the first Project 2061 publication, answered the question of…

This study proposes an empirical classification of ways to introduce elements of the history of science into science teaching, as well as describing a special way to do so characterized by the introduction of short extracts from historical texts. The aim is to motivate students to participate in problem-solving activities and to transform their…

The history of science shows that for each scientific issue there may be more than one models that are simultaneously accepted by the scientific community. One such case concerns the wave and corpuscular models of light. Newton claimed that he had proved some properties of light based on a set of minimal assumptions, without any commitments to any…

Discusses some principles of biological taxonomy. The evolutionary principle in taxonomy and its limitations, and the difference in evolutionary patterns between plants and animals, are also discussed. (HM)

Discusses historical views of the atom. Presents the philosophical view, the chemist's view, the physicist's view, the theorist's view, the quantum mechanical view, and the modern view. (Contains 24 references.) (DDR)

Presents an overview of the goals of the MindWorks program for science curriculum development. The project hopes to address student motivation, student understanding of the structure and workings of the physical world, and students' and teachers' ideas about the process and culture of scientific activity. Also discusses the progress of pilot…

Suggests that disinterest in physics occurs because students and adults can apply everyday concepts to solve problems without understanding the underlying physics concepts. Proposes Wagenschein's Exemplary-genetic Method to teach physics and illustrates the method with examples taken from history. (MDH)

Assesses students' learning of evolution by natural selection within four different sections of an introductory biology course where each section used a different combination of curricular materials and instruction. Reports that comparisons between sections support the use of paired problem-solving instructional strategy in conjunction with the…

Many didactical difficulties encountered in contemporary school physics are due to an outdated philosophy of science as illustrated by the energy concept, an example of a theoretical term which cannot be defined operationally with the help of simple measurement operations. (Author/DS)

Presents the nine teaching units in the history of science, by Klopfer, which can be used for instruction at the ninth and tenth grades. Each of these units, which are designed as case studies, consists of a student booklet and a teacher's guide. (HM)

Explored are the following dimensions of scientific literacy: the ethos of modern science and the cumulative achievements of science and technology in the history of the United States and in the nature of contemporary society. Also discussed is the reform movement in science education. (KR)
