The aim of this study was to learn from students' frame of reference how they experience foreign language classes. Data include learning diaries written during 2005 for more than 35 weeks (March to November). Subjects were 95 Argentine, Caucasian, mostly female, middle-class, Spanish-speaking College students between 19 and 21 years of age who were enrolled in English Language 11 at the National University of La Plata in Argentina. The results of this study stress 1) the value of systematic learner introspection over time as a vehicle for reflection and autonomy in foreign and second language learning contexts; 2) uncovering learners' thoughts and beliefs in an effort to understand how these affect their engagement with language activities; and 3) using this Information to make instructional decisions and monitor their adequacy and effectiveness.
