In the early days of DNA manipulation, DNA fragments were laboriously separated by gravity. In the 1970s, the powerful tool of DNA gel electrophoresis was developed. This process uses electricity to separate DNA fragments by size as they migrate through a gel matrix. This animation from Cold Spring...

This lab activity from the Biotechnology Alliance for Suncoast Biology Educators (BASBE) introduces the methods of RFLP analysis, or DNA fingerprinting, by using gel electrophoresis. Students will learn the role of restriction enzymes in DNA fingerprinting. Required materials, procedure and...

This lab activity from the Biotechnology Alliance for Suncoast Biology Educators (BASBE) provides instructions for conducting a gel electrophoresis lab. Students will try to solve a paternity case with this activity by obtaining a DNA fingerprint from each potential father, the mother and the child....

This lab, presented by the National Nanotechnology Infrastructure Network, covers the concept of material properties. Students will create a microfluidic device to show "the importance of channel design in biotechnology and nanotechnology and the methods used to study the behavior of fluids as they...

This 20-page paper from Elizabeth Fennema examines the topic of gender differences in learning mathematics. This paper examines changing beliefs about how women learn math, such as a preference for learning cooperatively, and reviews intervention programs for girls and women. Feminist perspectives...

This paper describes a study identifying factors related to gender differences in tenth grade science performance. An earlier study of eighth grade science performance found that gender differences were related to subject matter, student ability level, and frequency of hands-on lab opportunities. By...

This 8-page classroom evaluation, authored by Elissa Milto, Chris Rogers, and Merredith Portsmore of Tufts University, addresses gender differences between students in a college introduction to engineering class. As summarized in the abstract, "The aim of this classroom evaluation was to gain a...

This 10-page literature review, provided by Virginia Polytechnic Institute and State University, covers studies of gender differences in learning math, science, and technology. The possibility that female students think and learn differently as well as interact with equipment differently from boys...

This 5-page article, written by Donna Milgram of the National Institute for Women in Trades, Technology & Science, explores the gender differences in teaching science, technology, engineering, and math (STEM). "There are gender differences in learning styles specific to science, math, engineering...

This 4-page report from Sheila Tobias discusses issues related to women in mathematics and science. Key aspects explored include math anxiety and coping strategies, as well as important research on classroom conditions for female math and science students.
