Presents important information for conducting authentic scientific field work. Interprets one teacher's field experience in the Pacific Northwest. Points out the need for teacher training in authentic field work and makes suggestions for starting a field ecology project. (KHR)

Describes unexpected experiences with student laboratory activities. Makes recommendations for addressing two types of lab disasters: (1) when lab preparations fail prior to the beginning of lab; and (2) when students produce unexpected results with the proper use of materials. (Contains 11 references.) (WRM)

Presents some strategies that have been used to overcome problems in instructional areas of introductory biology programs. Focuses on maintaining an emphasis on inquiry, developing the process of science, the design of process laboratory activities, reducing cookbook laboratory orientation, and educating staff. (CW)

Discusses the main objectives of ecohistory and sources of information for this study. Details five themes that are important for students to know about the history of ecology including the history of Earth, fauna and flora, the human species, human civilization, and changes in the human environment. (CW)

Discussed is the value of using essays and other popular writings as supplemental material for advanced placement biology courses. Their value as motivators and as views of the everyday work of scientists is stressed. (CW)

Describes a method to produce 35mm color slides directly from the display screen of a computer terminal using techniques and equipment available to most teachers and researchers. Discusses the hardware and software needed, procedures, some of the problems encountered, and the potential uses of this method. (CW)

Describes three criteria for evaluating educational software; classification of software types, the presence or absence of process skills, and educational practices. This article provides background for a software evaluation form to appear in a subsequent issue. (CW)

Describes the state-of-the-art in computer interfacing in the biology laboratory. Discusses hardware and software. Enumerates the educational benefits from instrumentation such as cost effectiveness and increased student opportunity and motivation. Includes 14 references. (CW)

Risk assessment (the identification of hazards, the determination of the probability of a hazardous event occurring, and an estimation of the severity of such an event's occurrence) is suggested as a technique to be used to analyze current issues in environmental education in an objective manner. (PEB)

Discusses the use of computers for nine different tasks in biological education: information retrieval, data accumulation, data analysis, simulation and systems analysis, decision making, experimental control, course review, computer-managed instruction, and word processing. (PEB)

The use of toluidine blue as a stain for plant tissues is advocated. Directions for hand-cut tissue staining are provided. (PEB)

A study conducted by high school advanced bacteriology students appears to confirm the hypothesis that the incremental administration of antibiotics on several species of bacteria (Escherichia coli, Staphylococcus epidermis, Bacillus sublitus, Bacillus megaterium) will allow for the development of antibiotic-resistant strains. (PEB)

Scientific challenges are presented to motivate secondary and college students in creative thinking and scientific problem solving. Student solutions to the "Create-a-Creature" challenge are presented and six new challenges are issued. (PEB)

Presented is a brief review of the literature concerned with student evaluation of teaching. The interpretation of the results of these evaluations as well as suggestions for designing a useful instrument are discussed. (CW)

This review summarizes the different candidate AIDS vaccines currently being developed and outlines some of the problems attending vaccine research. (PR)
