Describes step-by-step techniques that can be used to develop educational simulations for undergraduate biology students. Also discussed are simulations that are currently being developed with the support of the National Science Foundation. (ZWH)

Describes an interactive simulation model which can be used to demonstrate population growth with discrete or overlapping populations and the effects of random, constant, or density-dependent mortality. The program listing (for Commodore PET 4032 microcomputer) is included. (Author/DH)

Presented is a simulation program for Apple II computer which assays the effects of a series of variables on bacterial growth and interactions between microbial populations. Results of evaluation of the program with students are summarized. (CW)

The educational design of a project option in an Open University course on evolution is described. Also described is the simulation which models the genetic and evolutionary consequences of two populations of a species of flowering plant coming together after a period of genetic isolation. (Author/JN)

Described is a computer program, AQUASIM, which simulates interaction between environmental factors, phytoplankton, zooplankton, and fish in an aquatic ecosystem. The conceptual flow, equations, variables, rate processes, and parameter manipulations are discussed. (CW)

Modeled after the program "Mastermind," this program teaches students the art of protein sequencing. The program (written in Turbo Pascal for the IBM PC, requiring 128K, a graphics adapter, and an 8070 mathematics coprocessor) generates a polypeptide whose sequence and length can be user-defined (for practice) or computer-generated (for…

Describes a computer-based instructional unit in cardiovascular physiology. The program (which employs simulated laboratory experimental techniques with a problem-solving format is designed to supplement an animal laboratory and to offer students an integrative approach to physiology through use of microcomputers. Also presents an overview of the…

Describes a sequence of five computer programs (listings for Apple II available from author) on tactic responses (oriented movement of a cell, cell group, or whole organism in reponse to stimuli). The simulation programs are useful in helping students examine mechanisms at work in real organisms. (JN)

A computer program that simulates the random evolution of a metabolic pathway is given. The program shows that natural selection preserves favorable traits if they occur in a specific sequence. (KR)

Discusses the advantages of basing computer simulations on analogues of nature rather than mathematical models. Explains the concept of heritability and describes how a computer simulation can help undergraduate students understand this concept. (ML)

This study examined the impact of a biology course emphasizing computer simulation on student achievement and student attitudes toward science. The students in the experimental group were placed in a class limited to 16 students to have 2 students to each computer. (YP)

Misconceptions, shown to be prevalent in students even at the college level, may affect the cognitive process of making predictions in biology. The purpose of this study was to: (1) identify students' misconceptions about important biological concepts; (2) identify students' cognitive behaviors associated with making predictions about these…

An integral part of the curriculum in introductory biology courses is the study of Mendelian genetics. Results from genetics learning studies and needs assessments demonstrated the need for additional intensive research in biology education and genetics learning. There exists a lack of detailed information describing reasoning patterns and…

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

Many assert that the use of animals for dissections in the secondary and undergraduate class is unnecessary. This article describes a study conducted to compare the attitudes and achievement of students who use interactive methods instead of conventional dissection. (ZWH)
