The experimental pilot project was conducted to determine whether students who take the laboratory phase of an engineering technology applied electricity course in a mobile laboratory at branch schools demonstrate proficiency comparable to students who take the applied electricity course in permanent facilities at the parent institution. The project design used the type of laboratory as the independent variable and an achievement test as the dependent variable. Analysis of co-variance was used with the pre-test scores held constant. The mobile laboratory was used 1 day each week at two branch schools and provided space for 16 students with equipment similar to the laboratory equipment at the parent institution. During the first operational period no significant differences were found between the final achievement test scores of students using the permanent laboratory and those using the mobile laboratory. However, during the second operational period final achievement scores of the students using the permanent laboratory were significantly higher, and it is inferred that the permanent laboratory facility makes for better proficiency in applied electricity than does the mobile laboratory facility. The appendixes present pictures of the mobile facility, a course outline for the applied electricity course, and a sample pretest, post test. (HC)
