The National Center for Biotechnology Information Entrez Direct (EDirect) software facilitates programmatic access to numerous biomedical, chemical, and literature databases from within a Unix terminal. EDirect has traditionally been used for command line access to NCBI data within the fields of computational biology and bioinformatics. This…

This study explores how teachers developed and critically evaluated a range of teaching strategies that could support the discussion of a socio-scientific issue (SSI) that had the potential to be controversial. The issue was stem cell research and six New Zealand teachers of senior biology students (grades 12/13) took part in an action research…

Increasingly, the general media cover new advancements and research in the field of biology. Stem cell research, emerging diseases and bioethics are some of the issues gaining public attention. The rate of increase of these new developments creates additional challenges to teachers of biology as they try to remain abreast of new information and…

Bioinformatics has emerged as an important discipline within the biological sciences that allows scientists to decipher and manage the vast quantities of data (such as genome sequences) that are now available. Consequently, there is an obvious need to provide graduates in biosciences with generic, transferable skills in bioinformatics. We present…

Details a simulation that employs a paper-and-pencil model to demonstrate the principles behind automated DNA sequencing. Discusses the advantages of automated sequencing as well as the chemistry of automated DNA sequencing. (DDR)

Describes a project that began as workshops for teachers in biotechnology and became a program that enables students to do hands-on biotechnology experiments in the classroom. The three parts of this program include the development of activities, access to equipment, and further workshops. (DDR)

Describes a laboratory protocol optimizing the conditions for the assay of pepsin activity using the Coomasie Blue dye binding assay of protein concentration. The dye bonds through strong, noncovalent interactions to basic and aromatic amino acid residues. (DDR)

Discusses applications of recombinant DNA technology and the controversies surrounding that technique. Provides a cooperative learning project idea that involves teams of students investigating and debating these issues. (DDR)

The purpose of this article is to discuss "small-group apprenticeships (SGAs)" as a method to instruct cell culture techniques to high school participants. The study aimed to teach cell culture practices and to introduce advanced imaging techniques to solve various biomedical engineering problems. Participants designed and completed experiments…
