This handbook was prepared for use by the various ethnic associations in Canada whose members want to find effective means of helping their children learn or maintain their ancestral language. The program described involves the use of recreational activities for language instruction, based on the theory that the nature of and motivation for recreational activities make them an effective vehicle for language learning. It is believed that a recreational situation enhances the learning process because no artificial motivation is required; activities are enjoyable, interesting and purposeful to the individual; and the highly emotionalized nature of recreational situations gives them a potential for learning. The principal focus is on oral comprehension and fluency in the ancestral language in question. The four basic steps in the development of a local LaRec program are discussed in detail. They are: (1) the preparation of a proposal, including identification of objectives, expenses, sources of income, and local variables; (2) preparation of a general scheme, including identification of objectives for one season, organization of appropriate activities, fund raising, and obtaining supplies and personnel; (3) carrying out the LaRec program for a season; and (4) evaluation of the program. The appendices provide references, instructions for building tables for a preschool play group, and number and counting activities for language practice. (CLK)
