(CS)

Discusses the applicability and advantages of using yeasts as popular and ideal model systems for studying and understanding eukaryotic biology at the cellular and molecular levels. Cites experimental tractability and the cooperative tradition of the research community of yeast biologists as reasons for this success. (RT)

Comparison of medical students' performance on the National Board of Medical Examiners test, Part I, indicates that the replacement of scheduled instructional time (i.e., lecture-based instruction) with a guided problem-solving program was not detrimental to test scores. (MSE)

Suggests that microbiology activities/experiments are suitable for teaching skills in designing experiments, manipulating tables/graphs, and the rewriting of work. Shows how students design an experiment using a table and how another experiment provides material for a group discussion on writing and rewriting. (DH)

This publication encourages student involvement in biological research through student research with the cooperation of teachers and scientists. The contents of the book are divided into two sections. The first section introduces students to research investigations and includes: (1) "How the Investigations Are Set Up and the Rationale Behind…

Bioinformatics embraces powerful new knowledge and techniques which, Janus-like, promise advances in medicine and agriculture and threaten new weapons for warfare. To guard against misuse of bioknowledge, nations must foster free international communication against experts. (Author)

Describes a laboratory exercise which applies Koch's Postulates to a plant disease, bacterial speck. Includes an explanation of Koch's Postulate, list of equipment needed, advance preparation, outline of the three-week activity, and variations of the laboratory exercise. (DS)

Briefly reviews the early history of industrial microbiology and discusses industrial fermentation practices and the role of recombinant DNA in the fermentation industry. (SK)

Described is an alternative method of culture isolation that uses streaking on specialized media. An activity in which different media are tested for selectivity is presented including a list of materials and procedures. A chart of colony morphology is given. (CW)

Presents research results on photosynthetic, carbon monoxide utilizing bacteria. Discusses applications of the research and offers three sets of experimental procedures and data that students analyze to determine which bacterium from a soil sample uses carbon monoxide fastest. (Contains 21 references.) (MDH)

Provides instructions for teachers and students to culture protozoans for use in science laboratories. Sections include setting up a culture area, basic culture media, amoeba culture technique, powdered milk-wheat-rice medium, alfalfa medium, and uses of the protozoa in the laboratory. (PR)

Describes a technique to isolate unsheared bacterial DNA and subject it to restriction endonuclease enzyme digestion. (MDH)

Studies the use of a computer-assisted learning simulation episode during a unit on the growth curve of microorganisms in grade ten. Finds no significant gender differences in either the experimental or control groups. Contains 25 references. (DDR)

Introduces a study that identifies which learning styles are prevalent in biology majors. Uses the findings of the study to design a microbiology course. Presents activities that address the different learning styles. Uses self-assessment and portfolios for student evaluation. Includes recommendations for instructional improvement. (Contains 19…

Describes the development, preparation, and use of a medium that can select against a wide variety of Gram-negative bacteria while still allowing growth and differentiation of a wide range of Gram-positives. (WRM)
