This single case study addresses an action research design (Wolcott, 1994) that utilizes observations, interviews, and documents to access what teaching and learning techniques have improved the acquisition of vocabulary of a single intermediate English language (EL) learner from Turkey. Findings are reported and discussed in terms of the student's perceptions of vocabulary learning. The study indicates that there were gains in vocabulary knowledge and use as well as progression of strategies. In addition, findings also show that the student failed to utilize advance vocabulary strategies when he needed them the most. Implications for future studies for diversified learners are also discussed. (Contains 1 table.)
