Resumen
Incorporation of previously reported AR technology (ARiEL) for a general chemistry laboratory was attempted for the second time, a replication effort designed to provide students with an option to read about the nature of instruments used in an experiment. Students’ app usage was tracked to understand the type and amount of information accessed, and the original Attitudes toward the Subject of Chemistry (ASCI) was modified and validated using confirmatory factor analysis (CFA) to measure students’ attitudes toward instrumentation. The results of these assessments indicated that students preferred information directly related to the target experiment, and the amount of time spent accessing information deemed less essential to the task at hand was not substantial. Nevertheless, the modified ASCI measurements suggested positive changes in both cognitive and affective domains of students’ attitudes, overall. These results were in agreement with the initial study of ARiEL, implying that an additional system such as ARiEL could be helpful for general chemistry students in making instrumentation more approachable.
