Project 5 of the GUME study on foreign language teaching methods continues the work of the previous projects concerning the relative effectiveness of a habit-formation (implicit) method and a cognitive-code learning method, with explanations in either the source or target language. The educational problem of Project 5 is teaching the English passive voice to Swedish students in Class 8. The teaching procedures and design differ slightly from the first three projects. The time for explanations varies between the source-language and target-language methods. The source-language method uses comparisons with corresponding structures in the source language where applicable. No significant differences in the learning effects of the three methods are evidenced; interesting trends, however, are noted and discussed. This report presents details on project design, lessons, and evaluation instruments. A statistical description of the experimental population is provided along with a statistical analysis of the results and a correlation study of the variable factors. A discussion of the results and their implications follows. A bibliography is included and appendixes provide details on the English grammatical explanations and on some of the evaluation instruments used.
