This study, illustrating how branch programing is conceived within the framework of linguistic theory, gives some insights on programing language material, specifying terminal objectives, and identifying the behavior by which achievement is measured. The model program described is an audio and motion film program with the main terminal objective of target language comprehension. The study examines preparation of behavioral analyses and selection of facts, skills, attitudes, and concepts relevant to the attainment of Spanish comprehension. As a necessary adjunct, it also shows how to construct frames appropriate to the nature of the level of language being taught and the type of learning involved, including discrimination, recognition, comprehension, and memorization. It discusses how to conduct and prepare tests both for individual use and for language laboratory use. Finally, it shows how to revise frames according to error rate, interference considerations, and student results of tests based on terminal objectives. (Author/RL)
