Discusses three types of sensors; pressure, gas detection, and relative humidity. Explains their use for laboratory measurements of gas pressure and detection of specific gaseous species. Shows diagrams of devices and circuits along with examples and applications including microcomputer interfacing. (RT)

Describes study designed to investigate students' attitudes and strategies when writing with the aid of a computer. Interviews with four undergraduates enrolled in a computer-assisted section of advanced composition are discussed, and participant observation and document analysis are also used to examine the combined processes of composing and…

Discusses how problem-solving networks can be incorporated into courses. Reports on the development of a new style of pictorial network that can assist students in the handling of experimental data. (CW)

Describes experiments designed to measure the oxygen content in the atmosphere and related areas in the high school laboratories. Considers the application of these activities to other programs. Includes a description of the binuclear complex and recommended procedures. (CW)

Describes an experiment for undergraduate chemistry laboratories involving a chemical found in plants and some sea animals. Discusses collection and identification of material, a hemolysis test, preparation of blood-coated agar plates, and application of samples. (CW)

A survey of college students' attitudes toward use of the language laboratory found that an initial positive attitude toward the laboratory in the first semester becomes more negative during the second semester, suggesting that new instructional materials are needed to maintain the initial favorable attitude toward the laboratory. (CB)

Described are the Howard Hughes Medical Institute programs for providing funds to assist science education. One program is designed to assist private liberal arts colleges that are not affiliated with a graduate school. Other programs have been established to provide support for postdoctoral research and laboratories. (RH)

Eighth grade physical science students studied graphing with a microcomputer as the lab partner in a microcomputer based laboratory. Graph templates were used to solve problems based on previous learning. It was concluded that the Computer as Lab Partner curriculum was effective in teaching graphing concepts. (GDC)

Describes an experiment designed to give accurate values for both the absolute zero of temperature and the gas constant using very simple apparatus. (TW)

Discussion of local area networks (LAN) includes use in elementary and secondary education and in higher education. Topics addressed include cost of software, instructional advantages, administrative considerations, effective use of computer labs, and computing capacity of microcomputer workstations. A list of LAN vendors and their products is…

Describes a program in which senior engineering students are given the opportunity to design, make, and test apparatus intended for an upper-level teaching laboratory. Discusses such projects as a vapor compressor test stand with refrigerant mass flow measurement, a double-walled concentric annular heat pipe, and a vacuum filling station. (TW)

Describes use of computer simulation which generates bird songs so that students can analyze song motifs and sequences as an introduction to descriptive analysis of behavior in an animal behavior course. Advantages of the simulation are discussed together with computer hardware/software needed and data presentation, analysis, and generation…

In 1984 the vocational studies department of a New Jersey high school transformed its industrial arts program into a technological studies department designed to prepare students for college and emerging job markets. A high technology laboratory with sophisticated energy, communications, computer, and video equipment was created to accompany this…
