Background information, list of required materials, and procedures are provided for an immunological assay which has been modified for use as a classroom/laboratory demonstration of antigen-antibody reaction. The assay is designed for a two and one-half hour laboratory period but may be modified for one hour laboratories. (JN)

Presented is an annotated bibliography of 24 books on DNA and genetic engineering. Areas considered in these books include: basic biological concepts to help understand advances in genetic engineering; applications of genetic engineering; social, legal, and moral issues of genetic engineering; and historical aspects leading to advances in…

Discusses some of the major genetic information processes which may be modeled by computer program string manipulation, focusing on replication and transcription. Also discusses instructional applications of using string models. (JN)

Former President Jimmy Carter discusses the "Global 2000 Report" and the need for coordination, political leadership, unified action, research and development, and for education. A list of recommendations based on the issues and topics discussed is included. (JN)

Describes nine commercially available programs which represent one aspect or a portion of the human ecology theme. Other information supplied for each program includes: program objectives; methods of instruction; specific subjects, grade, and ability levels; materials produced and purchasable; program implementation; teacher preparation; program…

Discusses the history of human ecology, providing a definition of this area of study. Also discusses human ecosystems as applied ecology and the values and ethics of the human environment. (JN)

Understanding and teaching about the environmental predicaments of humankind starts with four basic ideas: (1) the world population; (2) world resources; (3) biogeochemical cycles; and (4) thermodynamics. Each of these basic ideas is discussed. (JN)

Describes a laboratory study in which students evaluate, in ecological terms, different landscapes representing ecosystems under varying degrees of human domination. Also discusses the context within which the study is arranged. (JN)

Offers various reasons why the study of parasites and the diseases they cause should be incorporated into classroom biology discussions. Examples of several parasitic diseases and their ecological significance are provided. (JN)

Presented is a recommended sequence for developing a slide-tape presentation. Steps include selecting a topic, determining objectives for the presentation, constructing a storyboard, writing the script, and recording the script. Comments on use of quotation, sound effects, built-in pauses, and use of student voices are included. (JN)

Describes typical instructional applications of computers. Areas considered include: (1) instructional simulations and animations; (2) data analysis; (3) drill and practice; (4) student evaluation; (5) development of computer models and simulations; (6) biometrics or biostatistics; and (7) direct data acquisition and analysis. (JN)

Transposons are transposable elements that carry genes for antibiotic resistance. Provides background information on the structure and organization of these "jumping genes" in bacteria. Also describes the use of transposons in tagging genes and lists pertinent references and resource materials. (DH)

Describes current methods for the synthesis of DNA. Also describes the use of DNA as a highly specific molecular probe and as an agent for the mutation of genes. (DH)

Discusses the main ethical issues generated by the new genetics and suggests ways to think about them. Concerns include "playing God," violation of the natural order of the universe, and abuse of genetic technology. Critical distinctions for making difficult decisions about genetic engineering issues are noted. (DH)

Describes a course in which students examined the social implications of biological research, discussed the individual's role in research and whether there is an honor code of science, and completed a simulation which involved private companies competing for a government research grant. Instructional strategies used with the exercises are…
