The author has rewritten rules for CIPW norm calculation and has written FORTRAN IV programs to assist the student in this procedure. Includes a set of problems utilizing the CIPW norm to illustrate principles of chemical petrology. (MA)

Presents a computer game which assists in learning the classification of igneous rocks and a simulation program which illustrates some aspects of igneous textures. (SL)

Described is a computer program used to calculate d-spacings (corrected for film shrinkage) and a weighting factor for measurements made on a Debye-Scherrer film. Two purposes are listed for the computer program: time reduction and increase of computer competance. (Author/DS)

Described is a set of FORTRAN programs, suitable for teaching and research purposes, that simulate contact and regional metamorphism. Equations, examples, program uses, and availability are discussed. (CW)

Reviews the following computer programs: "Restless Earth" (National Geographic Society); "Science Cap 2.0" (DEMCO); "My Own Stories (MECDC); Wild Science Arcade (Binary Zoo); "Out and About" (Optical Data); "Botanical Gardens" (Sunburst); "BodyScope" (MECC); and "Mineral, Where and Why?" (Arizona Board of Regents). (PR)

Presented is a description of a BASIC program to be used on an IBM microcomputer for calculating and plotting synthetic seismic-reflection traces for multilayered earth models. Discusses finding raypaths for given source-receiver offsets using the "shooting method" and calculating the corresponding travel times. (Author/CW)

Described is a computer program which accepts face data, performs all necessary symmetry operations, and produces a drawing of the resulting crystal. The program shortens computing time to make it suitable for online teaching use or for use in small computers. (Author/DC)

Presented are the background theory, program procedures, output display, and applications for this program which is designed to calculate the slip vector and the stress to normal stress ratio on an arbitrarily oriented fault plane. Program availability is discussed. Twelve references are listed. (CW)

Designed to investigate whether or not science teachers can positively influence student achievement in, and attitude toward, science, this study focused on a specific teaching strategy and utilization of a computer-based simulation. The software package used in the study was the simulation, Volcanoes, by Earthware Computer Services. The sample…

Described is the use of Thematic Mapper images in undergraduate geology instruction. The work of the Andes Project at Cornell University is discussed. Digitally enhanced illustrations of landforms in the Andes mountains of South America are provided. (CW)

Reviewed are seven computer software packages for IBM and/or Apple Computers. Included are "Windows on Science: Volume 1--Physical Science"; "Science Probe--Physical Science"; "Wildlife Adventures--Grizzly Bears"; "Science Skills--Development Programs"; "The Clean Machine"; "Rock Doctor";…

Describes a five year research project in plant ecology by successive teams of students. The aim was to identify environmental factors which were determining the distribution of the vegetation on a pitheap. Includes descriptions of vegetation, soil properties, and computer assisted analysis of results. (Author/CW)
