ABSTRACT: This report summarizes earlier reviews on research findings in FL teaching and outlines those principal conclusions which seemed to the writer to have the most adequate empirical justification. Five major topics are discussed: teaching methods in FL instruction, FL aptitude, the attainment of FL proficiency, the effects of motivation and interest in FL learning, and the goals and benefits of FL study. Nineteen conclusions are presented and their implications for FL teaching are discussed. Several recommendations for changes in the college FL curriculum are included.
