This is the second and final part of a review of educational research on children's ideas about gravity. The first part concerned students' understanding of how and why things fall. This article picks up the trail of research studies that address students' understanding of the more complex ideas of projectile motion and orbits and examines how the…

The active participation of women in the field of American history dates back to the earliest writings on the subject. The rich and long history of women writing, teaching and researching in the field of American History, however, is obscured by narrow disciplinary definitions of what actually counts as history and who is qualified to represent…

This paper examines the development of science content knowledge of elementary teachers (N=25) as a result of participating in a summer science Institute funded by the Massachusetts Department of Education and the National Science Foundation. The institute was designed to integrate the physical, life, and earth sciences by addressing the National…

One result of the ambiguity surrounding future jobs is a number of myths not only about what jobs will be available and what they will be like but also about how to prepare for them. The first myth is "40 years and out," the notion that people will work continuously with one organization until retirement. The reality is that individuals need to be…

The purpose of this study was to investigate the effectiveness of using conceptual change texts accompanied with small group work on ninth grade students' learning of ecology. The developed texts were constructed to remediation of students' misconceptions with accommodated new ones about ecology. Conceptual change texts were implemented in an…

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.

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…

While problem-based learning (PBL) has a relatively long history of successful use in medical and pre-professional schools, it has yet to be widely adopted by K--12 teachers. This may be due, in part, to the numerous challenges teachers experience when implementing PBL. In this paper, we describe specific hurdles that teachers are likely to…

As a part of a doctoral thesis considering the history of teaching physical and chemical change, 641 chemistry/science textbooks have currently been examined.
