Experiential discovery laboratory exercises and computer-aided instruction (CAI) are both effective pedagogic means for complex science learning. The combination of these two techniques into computer aided laboratory instruction (CALI) has the potential for being a highly effective teaching method with several attractive side benefits. These side benefits include: significantly reduced supervisory and grading workload, reduced laboratory equipment cost, and reduced laboratory space. These side benefits are achieved through unattended, open laboratory operation and computer grading of the laboratory exercise. Only one laboratory station is required, and students can conduct the experiment whenever the equipment is available. This paper reports initial progress on the development of a CALI experiment using the LabView G programming language. The objective of this experiment is to determine the relationship between pressure drop and fluid flow rate for water flowing through capillary tubes and orifices. The total CALI experience consists of: • Completing a computer-administered qualifying test, • Diagramming the flow circuit on the computer screen, • Selecting appropriate virtual instruments, • Placing and connecting the physical hardware, • Sampling and logging data, and • Completing a computer-administered post-test. Initial results show enhanced understanding of the relationship between pressure drop and fluid flow rate by students performing the CALI experiment. Observation of the students during the experiment indicated a positive benefit from the hands-on experience of their handling and connecting the physical hardware. CALI participants evidenced greater awareness of the function of the various components than did the control group performing a comparable, traditional, laboratory experiment.
