The Language Teacher's Portfolio: A Guide for Professional Development is written for use by both preservice and inservice teachers. It links elements of educational practice and theory that students of education frequently find difficult to assimilate in language teaching. This text purposefully integrates material such as foundations of education, educational psychology, elements of planning and lesson preparation, reflective teaching, and classroom management issues into the reality of the language classroom. Thus, students of world language education are provided a holistic perspective of the challenges required to bring what may seem to be disjointed theoretical information into workable elements of classroom practice.
