USOE Projects 5-0683 and 7-0133 (Pennsylvania Foreign Language Projects entitled "An Assessment of Three Foreign Language Teaching Strategies Utilizing Three Language Laboratory Systems" and "A Comparison Study of the Effectiveness of the Traditional and Audiolingual Approaches to Foreign Language Instruction Utilizing Laboratory Equipment") were continued into Levels III and IV. The conclusions support earlier findings that students learning foreign language through a cognitive approach continue to achieve significantly better than audiolingual students.
