Describes an intelligent tutoring system named MENDEL, including problem GENERATOR, TUTOR, student MODELER, ADVISOR, hypothesis CHECKER, and problem SOLVER. This software may be used by high school or university biology students as a tool for learning concepts and problem-solving strategies in transmission genetics. (YP)

Compares the abilities of pre-nursing and mainstream chemistry students in general chemistry courses. Finds no significant difference between the populations. Lists topics covered, representative test questions, and performance comparisons. (MVL)

Abstracts six conference papers from the ISRAEL Association for Computers in Education. Included topics are spreadsheets for problem solving, concept acquisition with microcomputers, numerical mathematics, learning math as a science, studying polygons with LOGO, and a growth curve simulation of microorganisms. (MVL)

Discusses the reading problems that are concerns in a Science-Technology-Society program of science teaching. Describes possible origins of the lack of comprehensible reading abilities and the teacher's role in facilitating the process. (RT)

Describes a chemical engineering course for senior undergraduates and first year graduate students in biochemical engineering. Discusses five experiments used in the course: aseptic techniques, dissolved oxygen measurement, oxygen uptake by yeast, continuous sterilization, and cultivation of microorganisms. (MVL)

The lessons of 11 seventh-grade life science teachers were observed to determine the extent to which they made linkages between science content and its societal, reasoning, historical, or attitudinal implications. Results indicate a gap between scientific literacy as a normative goal of science instruction and current teaching practice. (TJH)

Cites the misconceptions that students beginning the study of electric circuits often have about electricity. Explains the use of capacitors with circuits of batteries and light bulbs to introduce electrostatic forces and help to alleviate the problem of misconceptions. (RT)

Reviews two software packages: Graphical Analysis III and Lewis Diagrams. Finds Graphical Analysis III to be a fast and versatile graphing program for high school science classes with access to Apple II microcomputers. Lewis Diagrams is designed to aid in determining Lewis structures of molecules and ions for IBM computers. (MVL)

Explores a graduate level bioprocess engineering course in protein purification and downstream processing. Designed to provide students with hands-on training in the design and implementation of product processing for the biotechnology industry. Includes syllabus and plan of study. (MVL)

Describes two computer programs used to aid in data analysis: (1) Develops a method for the propagation of error involving the direct calculation of the error in the dependent variable using a spreadsheet; (2) Examines a simple numerical method for solving complex equilibria. Lists a FORTRAN 77 program. (MVL)

Describes a chemistry laboratory software package for interfacing the Apple IIe for high school and introductory college courses. Topics include: thermistor calibration, phase change, heat of reaction, freezing point depression, Beer's law, and color decay in crystal violet. Explains the computer interface and the tools needed. (MVL)

Discusses the implementation and evaluation of the first full year of college freshman integrated natural science curriculum. Identifies separate courses in chemistry and biology as the foundation with physical principles as the unifying theme. Notes all instructors attended all classes. (MVL)

Discusses three aspects of electrochemical detectors: (1) signal and noise generation and signal-to-noise ratio, (2) improvement of qualitative information content, and (3) control of selectivity of the detector. Explains electronic principles of detectors and detection limits. Lists current applications and research. (ML)

Describes a new high school chemistry curriculum designed around societal issues by the American Chemical Society. Uses more organic and nuclear chemistry but less physical chemistry than regular courses. Stresses problem solving and citizen education in chemistry. Examines current implementation and support materials. Suggests liberal arts course…

Examined the effects of an instructional method used to remedy students' difficulties caused by fragmented and incorrectly interpreted knowledge. Described the method using explicit concept-interpretation procedures. Finds that the method helped to revise students' deficient prior knowledge about acceleration, and helped them to interpret it…
