Development and Evaluation of an Educational Data Acquisition System for Use in Secondary Schools. Technical Note 411.
Jernstedt, G. Christian; And Others
The purpose of this research was to design, create a prototype, and evaluate an Educational Data Acquisition System (EDAS) for use in secondary school science laboratories. The prototype of EDAS consisted of a microcomputer, data acquisition interface, sensors, software, and documentation. It provided the teacher and students with a general-purpose linkage between physical processes and the microcomputer and is comparable to the tools routinely employed in industry. The prototype system was tested for an entire school year in a local secondary school. An overview of the technical design and benefits of EDAS is provided along with a description of how the evaluation was performed. (EDAS was tested in a total of 19 different experiments where some class sections were taught using EDAS and other sections were taught using traditional methods.) The evaluation results confirm that EDAS is a powerful tool that can improve learning in crucial ways. (28 references) (Author/GL)
