This paper describes the design and results of a study carried out with elementary pupils ages 8-9 years on the topic of sinking and floating, with the aim of checking the validity of a general scheme for classroom activities based on a constructivist perspective. Children's "ways of looking" at buoyancy and the production of materials…

The collection of vignettes in this book provide science teachers with a multitude of source materials and useful alternatives for incorporation into their curricula and teaching. Teachers may select topics as brief issues for casual reflection or as a means for promoting deeper investigation and analysis. Most of the vignettes can be extended and…

Intended to help teachers for grades K-6 accurately present the events surrounding the first Thanksgiving, this guide features an historically accurate story for children, historical background for teachers, and activities for expanding and enriching instruction. The introduction discusses the need for teachers to be honest and informative about…

Many current studies have discovered that students tend to use either an Aristotelian or the Medieval impetus model rather than the Newtonian view in order to explain their experience. This preconceived knowledge may be important for students in learning mechanics. The purpose of this study was to identify and confirm the existence of a…

Since the 1970s, Outward Bound (OB) has borrowed psychological language and models to articulate its educational objectives and methods in terms accessible to mainstream educators. This report claims that OB's uncritical adoption of psychological language and models will undermine its commitment to certain core values of its tradition. This is…

As a part of a doctoral thesis considering the history of teaching physical and chemical change, 641 chemistry/science textbooks have currently been examined. These books are from many different countries and date from the eighteenth century to the present time. The books have described a wide variety of experiments to illustrate the difference…

This book attempts to reflect on the value and purpose of practical work as part of the science curriculum: why are practical exercises so necessary and what do they contribute to the science learning process? The chapters in this book examine issues such as: how practical work is perceived by students and teachers; the possibilities and perils of…

Showing evidence of planing multicultural education in curricula is required by the National Council of Accreditation of Teacher Education (NCATE) for accreditation of professional education programs. This paper presents discussions on this issue over the last three decades, points out the increasingly diverse student population in the United…

Reviews "Dismantling Desegregation: The Quiet Reversal of Brown v. Board of Education" (Gary Orfield, Susan E. Eaton), a book that describes the return of segregated schooling in U.S. cities and its relationship to segregated neighborhoods. Suggests that the book focuses on public policies while overlooking the importance of moral considerations…

Discusses the use of analogies and other instructional strategies (problem solving, demonstration, group labs, and large group discussion) in dealing with students' preconceptions in physics. (PR)

Discusses group process and design issues that should be considered when a group member has a hearing impairment. Different levels of hearing loss and the differing communication modes are reviewed; differences in cognitive processing based on communication mode are considered. Recommendations for accommodation are given. (LKS)

Presents 13 examples in which the intuitive approach to solve the problem is often misleading. Presents analysis of these problems for five different sources of misleading intuitive generators: lack of analysis, unbalanced perception, improper analogy, improper generalization, and misuse of symmetry. (MDH)

Reports a study (n=27) concerning the knowledge about image formation exhibited by students following instruction in geometrical optics in an activity-based college physics course for prospective elementary teachers. Student diagrams and verbal comments indicate their knowledge can be described as an intermediate state: a hybridization of…

Educator violence against students (verbal and physical assaults and the undermining of students' constitutional rights) erodes rather than enhances school safety. Unnecessarily harsh disciplinary practices create a violence-prone climate mirroring U.S. society--the most retributive of Western nations. Democratic classroom practices can help…

Describes junior high school students' understandings of some common non-technical words used in science classes and compares results for students in Botswana and England. Finds that considerable concerns remain about the way in which teachers use words in science. Concludes that the greatest problems occur with second-language students in…
