Describes microcomputer-based courseware designed for the simulation of the microbiological analysis of drinking water, including digitalized color images. The use of HyperCard is described and evaluation procedures are explained, including evaluation of the learning and of the class. The evaluation questionnaires are appended. (20 references)…

Presents the results of an analysis of science-classroom lab talk which focuses on topics and manner of talk as an approach to understanding the social context of undergraduate lab work. Argues that lab instructors should pay attention to how "scientific" the lab talk is, and to sociability among students. Contains 32 references.…

Nanotechnology is an emergent technology that holds much promise and excitement. The ability to control and manipulate matter at the most basic level--atoms and molecules--offers possibilities that transcend traditional science discipline boundaries. This interdisciplinary nature of nanotechnology provides many avenues for teachers to connect the…

This work describes outcomes of a research-driven advanced microbiology laboratory and literature research course intended to enhance undergraduate preparation for and contributions to original research. The laboratory section was designed to teach fundamental biochemistry and molecular biology techniques in the context of an original research…

Aphasia implies the loss or impairment of language caused by brain damage. The key to understanding the nature of aphasic symptoms is the neuro-anatomical site of brain damage, and not the causative agent. However, because "Herpes simplex" virus (HSV) encephalitis infection usually affects the frontal and temporal lobes, subcortical…

Outbreak! is an online, interactive educational game that helps students and teachers learn and evaluate clinical microbiology skills. When the game was used in introductory microbiology laboratories, qualitative evaluation by students showed very positive responses and increased learning. Outbreak! allows students to design diagnostic tests and…

This study investigated how academic norms, expectations and rules affect the experiences of graduate students, particularly in regards to reported academic misconduct at disciplinary and departmental levels. The study used a hierarchical linear analysis with data from a nationwide survey of 2,000 graduate students in chemistry, civil engineering,…

An audio-tutorial approach that has been implemented at Indiana University in Bloomington focuses on student learning rather than the mechanism of teaching. The basic component of an audio-tutorial course is a taped presentation that acts as a tutor, guiding the students through a sequence of readings, filmstrips, diagrams, tables, and other…

Presents as part I of a two-part series a study involving the intercellular transfer of bacterial DNA that codes for the resistance to antibiotics. Demonstrates to students that such transfers occur. Discusses laboratory procedures, materials and results. (CW)

Describes a simulation of the results of real experiments which use different strains of Escherichia coli. Provides an inexpensive practical problem-solving exercise to aid the teaching and understanding of the Jacob and Monod model of gene regulation. (Author/CW)

Results of a national dental school survey on microbiology instruction are presented, including data on the integration of microbiology with other courses, placement in the curriculum, class attendance policies, availability of advanced courses, and National Board reviews. Trends are discussed. (MSE)

This monograph contains 10 plant pathology experiments that were written to correspond to portions of a biology curriculum. Each experiment is suitable to a biology topic and designed to encourage exploration of those biological concepts being taught. Experiments include: (1) The Symptoms and Signs of Disease; (2) Koch's Postulates; (3)…

Techniques for examining terrestrial and aquatic microorganisms using flattened glass capillaries are described. Capillaries can be left in natural or artificial environments for appropriate periods of time and removed for direct microscopic examination. Examples of organisms observed using the technique are given and suggestions made for wider…

Described is a laboratory experiment that can be used to investigate bacterial survival in soil or water as well as the study of genetic transfer via conjugation. Discussed are materials, laboratory procedures, typical results, and a list of six references. (CW)

Describes a program in which second-year biology students use plasmid isolation to remove DNA from Escherichia coli bacteria and subsequently ligate and transform it into other E. coli bacteria. Cites ways teachers can get involved in current research that allows student participation. (RT)
