This article provides a historical overview of Modern Language Journal (MLJ ) articles that describe the teacher-learner relationship. From the earliest issues of the MLJ, authors have noted the importance of recognizing and responding to individual learner differences. This review focuses on how language learners have been portrayed in the MLJ and the implications of these portrayals for language teaching. It, thus, addresses the characteristics that language learners have been seen to possess and how language teachers have been urged to respond to these characteristics. Specific topics include foreign language aptitude, motivation and other emotional responses to language learning, reasons for student attrition, and advice for modifying instruction for different learner-types. This review also considers a number of articles written by language learners and addressed to their language teachers. Several recommendations are offered, including reinstitution of learner-authored articles in the MLJ and closer attention to the learner's voice in reports of classroom-based research.
