While different approaches to evaluation will yield different results, depending on the purpose of the evaluation this article describes an evaluation approach that was aimed at investigation of the mental models of users of the programme. The study was driven by questions about the differences in mental models of the instructional designers and…

In this study, we discuss the scaffolded design of ODRES (Observe, Discuss, and Reason with Evidence in Science), a computer tool that was designed to be used with elementary school children in science, and report on the effects of learning with ODRES on students' conceptual understandings about light, color, and vision. Succinctly, dyads of…

Constructing model hot air balloons is an activity that captures the imaginations of students, enabling teachers to present required content to minds that are open to receive it. Additionally, there are few activities that lend themselves to integrating so much content across subject areas. In this article, the authors describe how they have…

Our experience suggests that pre-service primary school teachers have problems with learning science, especially chemistry, and that this negative attitude towards science influences their future teaching. On that premise, the purpose of the study was to determine the level of the pre-service primary school teachers' intrinsic motivation for…

The study investigated the role of analogic instruction and reasoning level on the dependent measure of concept acquisition in an introductory college genetics course. The question of whether concept acquisition was facilitated through the use of instructional analogies was addressed. The control treatment consisted of expository instruction alone…

This teacher's guide features step-by-step instructions for activities that use easily-obtained and inexpensive materials as well as background information, literature connections, and assessment ideas. The unit allows students the opportunity to focus on observing and describing the properties and attributes of substances. In these activities,…

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 book contains scaled-down versions of Exploratorium exhibits that teachers can make using common, inexpensive, easily available materials. Each topic begins with a drawing of the original full-sized exhibit on the museum floor, a photograph of the scaled-down version which contains an introduction to the exhibit, a list of materials needed…

This book is based on the premise that learning in young children takes place through participation in purposeful activity and the learning process includes building on what children already know and enabling children to take responsibility for their own learning. It focuses not just on recent pedagogical developments in science, but shows,…

This paper describes research conducted in a classroom devoted to conceptual change instruction. The teacher in this class of fifth grade students at a midwestern parochial school made explicit attempts to have her students comment on the conceptions they held, their justification for those conceptions, and the status they attached to their…

In the domain of research on physics education, results on students' conceptions show difficulties in physics learning. This paper aims to propose theoretical elements to interpret such learning difficulties related to physics teaching in the case of heat and temperature. Sections in this paper include: (1) Introduction; (2) Epistemological…

Social semiotics suggests that social and cultural formations, including the language and practice of science and the ways in which new generations and communities advance them, develop as an integral part of the evolution of social ecosystems. Some recent models of complex dynamic systems in physics, chemistry, and biology focus more on the…

This article discusses ways for reflecting the present level of the natural sciences and their technical applications in secondary labor education. The author emphasizes ideas from the new interrelated branches of science, physical science in particular, that are developing at the interface of the classical sciences. (Author/RM)

Identifies 20 out of 108 science misconceptions, selected by 30 percent or more of a sample of 1,444 high school and university students in Lebanon. (MLH)

A science toy sometimes called the "magnetic spinner" is an interesting class demonstration to illustrate the principles of magnetic levitation. It can also be used to demonstrate Faraday's law and a horizontally suspended physical pendulum. The levitated part contains two circular magnets encased in a plastic housing. Each magnet stays…
