Using a computer and thermistor probes, students analyze graphs of temperature versus time. The experiment demonstrates phase changes in water, which can lead to a broader interpretation of matter, its properties, and the laws of thermodynamics. (Author/AIM)

Within large scale educational assessment agencies in the UK, there has been a shift towards assessors marking digitally scanned copies rather than the original paper scripts that were traditionally used. This project uses extended essay examination scripts to consider whether the mode in which an essay is read potentially influences the…

Describes the building and testing of a robust pressure sensor suitable for use in schools that produces an output that can be fed into a standard computer interfacing set. (Author/NB)

Describes the application of an integrated-circuit (IC) chip which provides an easy-to-use, inexpensive, rugged, computer-interfaceable temperature sensor for calorimetry and differential temperature measurement. Discusses its design and advantages. (JRH)

Describes the use of magnetic field probes interfaced to a microcomputer in measuring the magnetic field in and around a solenoidal "Slinky" spring toy carrying a current of a few amps. (JRH)

Describes a simple, inexpensive system that allows students to have hands-on contact with simple experiments involving forces generated by induced currents. Discusses the use of a dynamic force sensor in making quantitative measurements of the forces generated. (JRH)

Presents a simple but effective experiment that uses ultrasonic transducers and some basic electronics to study the speed of sound using the Doppler effect. Eliminates the noise problems associated with most sound experiments. Discusses the theory, and describes the apparatus and procedure. (JRH)

Describes a teaching method using computer probeware to enhance students' laboratory experiences. Discusses the role of computer probeware in the science classroom, how probeware affects learning, and how it affects efficiency. (KHR)

Describes simple inexpensive modifications to existing equipment that facilitate the computerization of interference and diffraction experiments done in introductory laboratory courses. (JRH)

Presents experiments that avoid using mercury by using pressure transducers to investigate the gas laws. (Author/JRH)

Presents three motion experiments that use magnetic switches for marking position and time involving an inclined plane, an air track, and sprinting. (JRH)

Describes a course for science education majors that explores the uses of computer-interfaced experiments in a variety of interesting activities. Several examples of biology experiments are given. (ZWH)

Describes the use of microcomputers in physics experiments to extend powers of observation, increase the accuracy of measurements taken, and obtain large amounts of high quality information, especially continuous and rapidly changing/moving data. Discusses software for interfacing a microcomputer with mechanics experiments. (JRH)

Contains an illustration and text to aid in describing the DynaPulse 200M Education Edition microcomputer-based laboratory (MBL), which combines interactive software with curriculum and medical instruction to teach students about the cardiovascular system. Review includes key features of the software, cost, and ease of use. (ZWH)
