Early Emerging Rules: Prepositions is a language tutorial and vocabulary enhancement program designed to train early grammatical constructions and facilitate the transition from single words to word combinations for individuals with developmental, visual, physical or language learning disabilities. This program uses speech, pictures, and animated characters and is intended as a follow-up to the vocabulary training provided by First Words, First Words II, and First Verbs (see entries). This program uses three 20-picture sets of different objects and containers to train the prepositions "in" and "on." The six instructional levels include a game, four levels of training, and a test option. Students are presented pictures and asked to select the picture which represents the construction being trained. Various amounts of instruction, cuing, and feedback are provided on each training level. The program trains the prepositions "in" and "on". For students with physical disabilities, alternative access may be gained through TouchWindow (see separate entry). COMPATIBILITY: For use with Macintosh and IBM and compatible computers.
