1985 | "Basal reading programs consist of graded and leveled series of textbooks, workbooks, teacher editions, tests and related supplementary materials for teaching developmental reading in the primary, intermediate, and upper grades. Such publications are characterized by the control of vocabulary and the sequencing of instructional experiences." [n.b. article discuses readers very much as being for native speakers and makes no mention of ESOL] |
