Understanding students' challenges about using microcomputer based laboratories (MBLs) would provide important data in understanding the appropriateness of using MBLs in high school chemistry laboratories. Identifying students' concerns about this technology will in part help educators identify the obstacles to science learning when using this technology. This study seeks to answer these two questions: (1) What advantages and challenges do students encounter during MBL activities? and (2) What are the views of high school chemistry students regarding the use of MBLs as a learning tool? The findings of the study included: (1) MBLs do not necessarily promote learning for all students; (2) special attention should be given to slow paced learners; (3) students feel challenged by MBL generated graphs; and (4) teachers should constantly be on the look out for graph anomalies that may simply be the result of misplugging of probes in the interface which may cause further graph interpretation confusion.
