Reviews computer programs for simulating experiments on (1) polymer sequencing; (2) genetic codes; and (3) cloning. Reasons for using such software are provided. (DH)

Describes the use of a chart that systematically summarizes three basic steps that involve DNA and its decoding in both eukaryotic and prokaryotic cells: replication; transcription, and translation. Indicates that the chart (mounted on a tranparency) does an adequate job of conveying basic information about nucleic acids to students. (DH)

Discusses current uses of microcomputers in schools. Also provides a rationale for educational computing based on economics, computer literacy, and equality of opportunity needs. Needs of educators, fears of educational computing, computer literacy in science education, and training science teachers to use computers are also discussed. (JN)

Discusses findings from a questionnaire survey of 622 biology teachers on: (1) how accurately they can judge readability of instructional materials; (2) what factors they consider when judging readability levels; and (3) if they considered differences in students' reading ability when selecting reading materials for them to use. (JN)

Background information, list of materials needed, procedures used, and discussion of typical results are provided for an experiment on the thin layer chromatography of chlorophyll pigments. The experiment works well in high school, since the chemicals used are the same as those used in paper chromatography of plant pigments. (JN)

Describes a useful instrument designed to increase student participation and class discussion. Based on student response to the system while it was being used, student feedback, and personal experience, the push-button system installed in the laboratory was determined to be a success. (JN)

Describes a computer program which allows the user to establish and maintain a file of up to 1,000 items. Items are stored alphabetically and may be searched. Copy of the program for Apple II Plus (DOS 3.3) may be obtained by contacting the author. (JN)

Discusses the life cycle of a fluke to illustrate a form of larval reproduction which occurs in many trematode flatworms. Polyembryony, production of many embryos by the breakup of the one early embryo that resulted from sexual reproduction, is considered. (JN)

Highlights status of compatability between bioeducational software and hardware. Also lists sources of software and 1984 workshops for bioeducators. (JN)

Indicates that although computers may churn out creative research, science is still dependent on science education, and that science education consists of increasing human experience. Also considers uses and misuses of computers in the science classroom, examining Edgar Dale's "cone of experience" related to laboratory computer and "extended…

Discusses graviperception and gravitropism by plant roots. Indicates that graviperception occurs via sedimentation of amyloplasts in columella cells of the root cap and that the minimal graviresponsiveness of lateral roots may be due to the intensity of their caps to establish a concentration gradient of inhibitor(s) sufficient to affect…

Lists and discusses goals of The World Campaign for the Biosphere and strategies designed to achieve these goals. Also lists eight suggestions for science teachers to help incorporate the goals into school curricula and programs. These include organizing assemblies which present information about environmental problems and presenting environmental…

Presents and discusses three sets of data indicating that teaching staffs in general, and biology teachers specifically, are, on the average, aging at an increasing rate. Implications for high school biology teaching are addressed; possible solutions to the problem are offered. (JN)

An audio-cassette lesson packet is suggested as a substitute plan. Procedures for developing such a packet are provided, including a sample script and worksheet on the topic of coping with death. (JN)

Discusses strategies used to integrate the teaching of high school biology and English. One major effort involved students writing and/or modifying the scripts for slide and filmstrip presentations. (JN)
