Second language learning today requires new materials. One type of learning unit suggested would have a simple format, limited scope and objectives, and diversity of content, form, learning strategies and activities. In spite of the problems involved in the production of this format, such units might be worked out in teacher-training programs, by centralizing services in school districts or possibly by publishers. A proposal of a practical frame of reference for such units is outlined in the form of a limited collection of parameters intended to help specify who is communicating, with whom, where, when, how and why. The first step in the process is a list of 17 language acts defined by a number of performative verbs. Because these language acts generally occur in sequences and in situations, simple sequential schemas and situations have to be prepared. Examples are given of six sequences and fifteen situations. Eleven examples of situations using the various parts of a proposed pedagogical framework, including suggestions for class presentation, complete the document. (AMH)
