Every time an English professor assigns a novel, poem, or play for a class to analyze, he or she is using the case study method. Why shouldn't scientists do the same? They don't always have to write their own material. After all, there are some pretty good writers out there, and some of them actually slip a lot of science into the nooks and…

This paper discusses the evaluation of an informal science education project, The Birdhouse Network (TBN) of the Cornell Laboratory of Ornithology. The Elaboration Likelihood Model and the theory of Experiential Education were used as frameworks to analyse the impact of TBN on participants' attitudes toward science and the environment, on their…

The purpose of this paper is to carefully examine the evolution of students' theory building and modeling, critical components of scientific epistemologies, over a unit of study on sinking and floating in one third/fourth grade classroom. The study described in this paper follows in the tradition of Design Experiments (Brown 1992, Collins 1990)…

The scientific model of how people see things is far removed from children's real-world experience. They know that light is needed in order to see an object, but may not know that light is reflected off the object and some of that light enters the eyes. In this article, the author explores children's understanding of reflection and how to develop…

Andreas Libavius' (c. 1555-1616) three part collection of letters, the "Rerum chymicarum epistolica forma...liber" (1595-1599) is a particularly important text in fashioning the subject of chemistry as a demonstrative science and as a didactic discipline. Where Libavius' "Alchemia", which some have claimed to be the first textbook of chemistry,…

This laboratory exercise affords students a hands-on experience learning about traditional dyes, fiber strength, and paper making. It is economical, simple to prepare, provides satisfactory results, and is student friendly. Dyes were extracted from plant leaves, stems, roots, and fruits. Hard-boiled eggs were place in the dyes for 15 minutes to…

In 1999, William Dembski became director of the newly established Michael Polanyi Center at Baylor University, thanks to the support of Baylor's president Robert Sloan. The center was, as Dembski observed, "the first intelligent design think tank at a research university." As such, it fulfilled a crucial objective of the "intelligent design"…

Nanotechnology deals with machines, materials, and structures and their behaviors at the scale of atoms and molecules, or the nanoscale. By working on this scale, scientists are able to create enhanced materials with desirable properties, such as stain-resistance. The authors developed the activity described in this article to introduce middle…

This article offers a specific example of the benefits that might result from integrating scientific principles into the daily practice of dance training. Using the mastery of turnout as our focus, we 1. describe the anatomy of turnout in terms familiar to the dance artist, 2. explore conditioning and imagery work designed to improve the use of…

Demonstrations are sometimes perceived as merely entertaining and expendable ancillaries for lectures and laboratory sessions. Nothing can be further from the truth. If done properly, demonstrations have much more value than lectures and labs when used to teach critical thinking in the sciences. There are effective ways to model scientific…

This article is about an investigation of six middle school science teachers' beliefs and instructional practice about the coherence of the science they teach as articulated by National Science Education Standards (NRC, 1996). Many well intentioned reform efforts focus on improving content knowledge of teachers, but many classroom teachers…

Elementary school children in the United States are not developing acceptable levels of mathematical proficiency (National Center for Education Statistics, 1999), and a major concern of teacher educators is that teachers lack the depth and flexibility of mathematical understanding and the corresponding beliefs they need to teach for proficiency…

The Colorado Model Content Standards for Science specify what all students should know and be able to do in science as a result of their school studies. Specific expectations are given for students completing grades K-2, 3-5, 6-8, and 9-12. Five standards outline the essential level of science knowledge and skills needed by Colorado citizens to…

This study investigates relationships between understanding of nature of science and four key factors elementary science teachers possess, which are: (1) Their specializations in different science areas (Physics, chemistry, and biology), (2) Gender issues, (3) How long they have been teaching in elementary school environments, (4) Their…

The study investigated the relationship between instructional context (integrated and non-integrated) that explicitly teaches about nature of science (NOS) and students' view of NOS across different disciplines. Participants were three teachers and their students, which comprised six classes of 89 ninth-graders and 40 10th/11th-graders. Each…
