Engaging students in the study of genetics is essential to building a deep understanding of heredity, a core idea in the life sciences (NRC 2012). By integrating into the curriculum the stories of famous scientists who studied genetics (e.g., Mendel, Franklin, Watson, and Crick), teachers remind their students that science is a human endeavor.…

Determining the acceleration of a free-falling object due to gravity is a standard experiment in physics. Different methods to do this have been developed over the years. This article discusses the use of video-analysis tools as another method. If there is a video available and a known scale it is possible to analyse the motion. The use of video…

The declining cost of computers and wireless networks has made laptop programs more affordable than ever. At the same time, the internet resources available to teachers and students have grown exponentially in the 15 years since web browsers first became practical. As a result of these trends, growing numbers of students nationwide are provided…

Since Robert Millikan discovered the quantization of electric charge and measured its fundamental value over 90 years ago, his oil-drop experiment has become essential in physics laboratory classes at both the high school and college level. As physics instructors, however, many of us have used the traditional setup and experienced the tedium of…

It is widely accepted that inquiry-based curriculum programs have positive effects on cognitive achievement, process skills, and attitudes toward science (NRC 2000). Science teachers seek engaging, effective, and inquiry-based activities that are standards-aligned and convenient to implement in their classrooms. For many years, the web has…

Describes the development and use of a web site designed to engage middle school students in problem-based learning while addressing science education standards related to cell biology, technology, social aspects of science, and the nature and history of science. Students learn about naturally occurring opiates as they solve a mystery and conduct…

Points out that a shift toward inquiry-based learning is one of the main tenants of a new approach to science education that also includes technology and the history and nature of science. Includes a sample lesson of how science educators can incorporate the Internet into the classroom. (DDR)

This study was designed to determine how students' engagement in a learning and debate activity on a current scientific controversy influences their understanding of the nature of science and, in turn, informs their decision-making on the issue. Two high school science classrooms, totaling 38 students from 9th through 12th grade, participated in…

Describes a website designed to allow students to publish their own accounts of school science investigations they have carried out. Makes suggestions for initiating computer-mediated student discussions of the nature of science based on information contained in the website. (WRM)
