This program, included in "Effective Reading Programs...," is designed to minimize initial difficulties in learning to read, to control early reading and word attack habits, and to meet a wide range of individual differences. Begun in 1966, the program serves an unselected cross-section of children in 110 kindergarten through third-grade classrooms in St. Paul, Minnesota, and is also used in other selected cities. In addition to readers, the reading program includes programed texts, reading and listening tests, letter forms, and linguistically related words. To prevent children from developing habits of using inappropriate cues in identifying words, the program uses a system of controlled word groupings to focus the child's attention on individual letters rather than on word length or configuration. Linguistic word groupings, programed texts with story-related pictures, and early attention to context clues are also combined in the series to meet the needs of children with different learning styles. A detailed teacher's manual eliminates the need for inservice or preservice training for the program. (TO/AIR)
