ABSTRACT

Commercially developed textbook programs typically contain at least three major components: student textbooks, teachers’ manuals, and tests for the assessment of progress. These comprehensive programs also offer a number of ancillary materials, most of which support the major components of a program. Ancillary materials come in a wondrous variety: word cards, big books, picture cards, wall charts, letters to parents, cumulative record cards, word lists, games, sentence boards, picture supplements, flash cards, audio tapes, film strips, workbooks, skill books, blackline masters, map books, lab manuals, software products for teachers and students to use on micro computers, and more.
