This report contains experiment results obtained from a comparative study of two groups of seventh grade students learning German in Sweden. The main objectives of the investigation, which lasted one school year, are: (1) to investigate possible achievement differences in German between similar groups of students when one group is instructed mainly in the language laboratory and another group in the classroom only, and (2) to investigate possible differences in attitudes between the two groups. Results are expressed statistically in 10 tables and illustrated graphically through 11 additional diagrams. (RL)
