A simple computer interface for controlling a compact spectrograph for use as a spectrophotometer in an undergraduate teaching laboratory was developed. The project was implemented on a Raspberry Pi computer which permits the integration of a light source into the software. The interface was written in Python to facilitate modification by the user…

The aim of this study was to investigate if integrating basic analytical methods and computer interface technology would result in a positive change in student attitude. Students' self-concept of science knowledge and skills (Capability), opinion towards science (Affect), and perceptions of the value of science (Value) were determined with…

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)

Computers are routinely used to control experiments in modern science laboratories. This should be reflected in laboratories in an educational setting. There is a mismatch between the power that can be delivered by a computer interfacing card or a TTL logic circuit and that required by many practical pieces of laboratory equipment. One common way…

Introduces an alternative method to determine the mechanics of a moving object that uses computer vision algorithms with a charge-coupled device (CCD) camera as a recording device. Presents two experiments, pendulum motion and terminal velocity, to compare results of the alternative and conventional methods. (YDS)

Studies the effect of V-Scope activities on the performance of 11th-grade students in analyzing kinematics graphs. Students were challenged to construct different kinds of graphs using their own movements as well as the motion of a dynamics cart. Results indicate that the V-Scope kinematics laboratory activities can promote kinematics concepts and…

Explains the use of the microcomputer as a multipurpose analytical instrument which frees students from the mechanics of science and allows for more active learning involvement. Provides the typical data acquisition configuration, advantages, disadvantages, and a brief summary. (RT)

The William R. Wiley Environmental Molecular Sciences Laboratory (EMSL) at the Pacific Northwest National Laboratory (Washington) is a collaborative user facility with many unique scientific capabilities. The EMSL expects to support many of its remote users and collaborators by electronic means and is creating a collaborative environment for this…
