The guide is one section of a resource kit designed to assist Peace Corps language instruction coordinators in countries around the world in understanding the principles underlying second language learning and teaching and in organizing instructional programs. This section addresses design and development of language curricula. An introductory chapter offers an overview of the guide, suggestions for identifying curriculum development needs, and a schedule for curriculum development tasks. Subsequent chapters outline a step-by-step plan for: conducting a needs assessment (working with questionnaires and follow-up interviews, open-ended needs assessments, curriculum development with limited time and resources, analyzing results), including some sample instruments; selecting and sequencing competencies (integrating competencies with major pre-service training events, grammar and a competency-based curriculum, integrating cross-cultural concerns, integrating cultural themes, identifying and integrating technical competencies and other sectors within the curriculum); developing instructional content, with sample curricula from the field; and curriculum assessment and revision.
