The goal of this laboratory exercise is to increase student understanding of the impact of nervous system function at both the organismal and cellular levels. This inquiry-based exercise is designed for an undergraduate course examining principles of cell biology. After observing the movement of "Caenorhabditis elegans" with defects in their…

Membrane transport is a fundamental concept that undergraduate students of cell biology understand better with laboratory experience. Formal teaching exercises commonly used to illustrate this concept are unbiological, qualitative, or intricate and time consuming to prepare. We have developed an exercise that uses uptake of radiolabeled nutrient…

A 14-week, undergraduate-level Genetics and Population Biology course at Morgan State University was modified to include a demonstration of functional genomics in the research laboratory. Students performed a rudimentary sequence analysis of the "Caenorhabditis elegans" genome and further characterized three sequences that were predicted to encode…

The present paper focuses on the application of a structured template, maximum impact flow (MIF), in order to encourage young students in the area of optics and optical engineering. MIF introduces a template in terms of individual steps and linked functionality and is shown to fuse separate learning tools together into a cohesive unit.…

Gill-breathing freshwater snails (Family "Pleuroceridae") are ecologically important, abundant in many streams in the United States, and easy to collect and maintain under classroom conditions. These snails can be used in classroom tests to demonstrate effects of pollutants on aquatic organisms. In more advanced classes, students can cage the…

Over the past 25 years, the author has had the opportunity to study the subject of solar energy and to get involved with the installation, operation, and testing of solar energy systems. His work has taken him all over the United States and put him in contact with solar experts from around the world. He has also had the good fortune of seeing some…

The oil drop experiment is considered an important contribution to the understanding of modern physics and chemistry. The objective of this investigation is to study and contrast the views and understanding with respect to the experiment of physicists or philosophers of science with those of authors of physics or chemistry textbooks and…

The purpose of this study was to investigate (a) what effect the use of interactive computer-based simulations (ICBSs), the use of laboratory inquiry-based experiments (LIBEs), and the use of combinations of an ICBS and a LIBE, in a conceptually oriented physics course, have on science teachers' beliefs about and attitudes toward the use of these…

Undergraduate biology programs are currently undergoing reform to involve students in biomedical research. Engaging students in more active, hands-on experiments allows students to discover scientific principles for themselves, and to develop techniques of critical thinking and problem solving. This models the world of real scientific research,…

"The Dirty Water Challenge" is a fun activity that teaches children about their environment in an engaging and practical way. Inquiry is embedded within the practical--students have to design, plan, and then build their own design of water filter. Students are exposed to important concepts from a variety of scientific disciplines, including how…

Teaching is essentially a personal and professional business in which lively, thinking, enthusiastic teachers continue to analyze their own activities and mediate the curriculum framework to their students. This book aims at encouraging teachers and curriculum developers to continue to rethink how science and technology should be taught in…

The purpose of the Toys in Space project was to create new ways for children to discover the joy and excitement of science and technology in the world around us. This book describes how familiar toys behave in the space environment where the downward pull of gravity is absent, and clearly documents those principles of physics that explain why the…

Project WET (Water Education for Teachers) is a nonprofit water education program for educators and young people. This curriculum and activity guide for kindergarten through twelfth grades is a collection of innovative, water-related activities that are hands-on, easy to use, and fun. The activities incorporate a variety of formats such as large…

This book is designed to help students understand the nature of scientific inquiry by involving them in doing science rather than merely reading about it. The content of the text emphasizes science process skills, mathematical skills, and the use of theories and models that are fundamental for learning the various science disciplines. The…

Instruction in Scientific Inquiry Skills (ISIS) is part of a seven-year Air Force effort--the Fundamental Skills Training Project--to design, build, evaluate, and transition advanced computer-aided instruction to the education community. This report describes ISIS 2.0 and presents the results of an initial field evaluation of the software during…
