This article is a presentation of a three-day sequence of lessons that engaged fifth-grade students in an exploration following the activities of scientists. From asking questions and analyzing data, to engaging in scientific modeling, to defending their theories to the scientific (classroom) community, these fifth graders were mirroring how…

In the 2 day lesson presented in this article, students explain how ionic substances interact in solutions by developing and revising their own explanatory models. The lesson engaged students in three-dimensional learning through creating and revising their own models to explain the interaction of ionic substances and polar molecules in a closed…

Addresses the most popular models currently being chosen for biological research and the reasons behind those choices. Among the current favorites are zebra fish, fruit flies, mice, monkeys, and yeast. Concludes with a brief examination of the ethical issues involved, and why some animals may need to be replaced in research with model systems.…

Discusses whether the discovery in 1956 that humans have a chromosome number of 46, as opposed to 47 or 48 as previously thought, fits into a paradigm shift of the Kuhnian type. Concludes that Kuhn probably would not have considered the chromosome number shift to be large enough to be a focus for one of his paradigms. (AIM)

Describes a theoretical model of the research and development process which allows students to develop research strategies based on their understanding of the generation of technical and scientific literature. Claims the model provides a conceptual framework of the structure of the literature students will be using in their professions. (MM)

Provides a model that maps out five stages of relating library and scientific research: (1) establish an interest; (2) narrow a topic; (3) clarify the variables; (4) refine the procedures; and (5) interpret the unexpected. Provides a student questionnaire for selecting a topic and a format for general note taking. (MDH)

Describes the use of Gowin's Vee to make the connection between lecture and laboratory, guide science fair research, help students decipher professional research journals, and make oral science fair or lab report presentations easier to understand. Provides examples of Gowin's Vee applied to research articles and comprehensive criteria for…

This booklet is a program management tool designed for use by high school students and teachers participating in science research programs throughout the United States as well as overseas. The program consists of a symposium during which students are invited to conduct original research in the sciences, mathematics, humanities, and computer…
