Described is an exercise which examines the effect of reading aloud a technical passage of science material while the heart is monitored by a computer. The experimental setup, design, and data analysis are discussed. (CW)

Discusses the sociohistorical approach to tools and change. Explores the possibilities of computer-supported cooperative work. Discusses formative experiments on the educational environment as research opportunities. Illustrates the organizational impact of school technology by describing a project intended to create an environment for…

The impact and uses of new technologies in science teaching are discussed. Included are computers, software, sensors, integrated circuits, computer signal access, and computer interfaces. Uses and advantages of these new technologies are suggested. (CW)

Described is an approach that uses a computer spreadsheet program to calculate entropy change at constant temperature and pressure. The calculated values can be used in an associated graphing program. (CW)

Describes a computer program presenting four genetics problems to monitor the problem solving process of college students. Identifies three main areas of difficulty: computational skills; determination of gametes; and application of previous learning to new situations. (Author/YP)

Describes two computer assisted tutorials, one on acid ionization constants (Ka), and the other on solubility product constants (Ksp). Discusses framework to be used in writing computer assisted instruction programs. Lists topics covered in the programs. (MVL)

Explains the operation of five relative humidity sensors: psychrometer, hair hygrometer, resistance hygrometer, capacitance hygrometer, and resistance-capacitance hygrometer. Outlines the theory behind the electronic sensors and gives computer interfacing information. Lists sensor responses for calibration. (MVL)

Studies the pressure and energy of particles interacting through a Lennard-Jones potential and correlates thermodynamical properties with system structural characteristics. Analyzes the relationships between computer simulated data and the van der Waals equation. (YP)

Describes a three-dimensional computer aided design software package, CADKEY, for demonstrating orthographic orthodirectional projection theory to a classroom. Provides several figures for showing the demonstrations. (Author/YP)

Use of probes and data-logging software to introduce dynamic line graphs to young children in the context of science investigations found this approach facilitated effective use of line graphs as models of relationships between variables. (Author/MKR)

This paper tracks the "computer attitudes" of over 150 undergraduates during their preservice teacher education program. Analysis includes a comparison of attitudinal change as a function of numerous demographic factors and a description of ways in which computers are being integrated into the preservice teacher education curriculum. (40…

Presents a lab experiment to demonstrate application of the iterative capability of spreadsheets. Activity involves a variable spacing parallel-plate capacitor and an electrometer. (PR)

A Particulate Nature of Matter Evaluation Tests was used to explore the effect of computer animations depicting the particulate nature of matter on (n=400) college students' mental models and comprehension of chemical phenomena. Treatment groups received significantly higher conceptual understanding scores than did the control group. (30…

Presents Texas Instruments' new Calculator-Based Laboratory (CBL), a hand-held device that connects to a graphing calculator, as a tool to make sophisticated measurements outside the classroom laboratory. Describes activities that use the CBL to make measurements in motion studies. (JRH)

Uses a moderately priced digital multimeter that has output and software compatible with personal computers to make a portable, computer-based data-acquisition system. The system can measure voltage, current, frequency, capacitance, transistor hFE, and temperature. Describes field measures of velocity, acceleration, and temperature as function of…
