Points out the challenges of educating students about bioethics and the limited training of many biologists on ethics. Discusses the basic principles of ethics and ethical decision making as applied to biology. Explains the models of ethical decision making that are often difficult for students to determine where to begin analyzing. (Contains 28…

Describes a Standards-based activity entitled "The Limits of Learning" that is inquiry-based and designed for high school biology classes. The activity concerns how well repetitious material can be learned and improved upon. (YDS)

Introduces a laboratory activity designed for an undergraduate developmental biology course. Uses Play-Doh (plastic modeling clay) to build a multicellular embryo in order to provide a 3-D demonstration of cleavage. Includes notes for the instructor and student directions. (YDS)

Defines dichotomous keys as common learning tools based on identification rather than memorization. Provides an example of a dichotomous key developed for introducing histology in human anatomy and physiology (A&P) courses and explains how students can use the dichotomous key. Discusses the goals of the exercises and the process of identification.…

Describes the inexpensive and safe method of using roundworms in the classroom or laboratories. Because parasitic infections are so common, students should learn about worms. Provides statistics on just how many people have a worm infection in the world. Explains how to study living nematodes, and obtain and use earthworms. (Contains 13…

Introduces the peanut observation activity to teach about the pros and cons of dissection. As an inquiry-based approach, dissection is one way to teach process skills. Lists the progression of the activity as observation, questioning and finding the answer, challenge, discussion, and further examination. (Contains 12 references.) (YDS)

Introduces a role playing activity that actively engages students in the learning process of mitosis. Students play either chromosomes carrying information, or cells in the cell membrane. (Contains 11 references.) (Author/YDS)

Introduces internet resources that are available for instructional use in biology classrooms. Provides information on video-based technologies to create and capture video sequences, interactive web sites that allow interaction with biology simulations, online texts, and interactive videos that display animated video sequences. (YDS)

Points out the inadequacy of visual information such as writing on a blackboard or using an overhead projector as the ability to develop an understanding of dynamic processes among students. Recommends using short animations that can be viewed on the World Wide Web. Describes how to make a GIF animation. (YDS)

Explains reasons for using writing assignments in introductory biology courses for non-science major students. Describes the structure of the writing assignments and discusses the outcomes. Lists guidelines for writing short papers. (YDS)

Discusses the conflict of creation versus evolution in education and challenges biology teachers in building a learning environment. Investigates the beliefs and ways of managing conflict of conservative Christians who were science teachers, future science teachers, science teacher educators, and scientists. Warns teachers against using strong…

Studies the effectiveness of biology teachers in the southwest Missouri area. Introduces the Biology Laboratory Internship Program which provides preparation and teaching experience to preservice teachers. (YDS)

Introduces teaching materials developed for field identification of plants with synoptical keys, identification tables, cards, and programs. Selects approximately 2000 seed plants and uses visibly identifiable characteristics for classification. Recommends using the methodology of identification in other areas for biological identification. (YDS)

It is difficult to incorporate long term studies such as ecology into classroom settings. Discusses how to reach and download research center data available on the web. Recommends Long Term Ecological Research (LTER) sites for downloading and interpreting data. Explains the downloading procedure using a Netscape browser, and uses Excel and Lotus…

Describes a laboratory activity investigating important concepts in microbiology and ecology in which students design and carry out their own experiments and learn about microorganisms. Points out that all microorganisms are not dangerous and studies the relationship between Methylobacterium and plants. (YDS)
