This monograph was developed to assist teachers in identifying more precise ways to select materials to use in promoting basic skills development. It is meant to be used primarily by teachers of third and fifth grade pupils who must achieve the skills measured in the State Assessment Test required by Florida. Examples are provided of test questions in reading, writing, and mathematics. Sources of instructional materials that reinforce specific skills are provided. These source books are made available throughout the state in teacher workshops conducted by the P. K. Yonge Laboratory School (University of Florida, Gainesville). The appendix includes a description of the workshop component, a pretest instrument, an example of the listings of achievement reports and test foil analysis, lists of reading and spelling words on which students may be assessed, a variety of game suggestions, a list of Statewide Assessment publications and materials that are available from the Florida State Department of Education, and a bibliography of books listed in this sourcebook.
