Writing and testing a programmed text on principles of biosystemics

Abstract

This thesis describes the procedure employed in writing and testing programed instruction on the subject of biosystematics. It briefly discusses similar studies that have been done with programed and other self-instructional materials. A review of the literature provides evidence that there is a need for such instructional materials in our modern schools.The thesis then describes the procedure that the writers followed in the writing, testing, and revising of the programed text, Principles of Biosystematics. Recorded in the appendices are the testing data which include the students# pre- and posttest scores and the item-analysis of the examinations used to test the first and second drafts of the program. These data were used to determine what parts of the program seemed weak or poorly developed, Such segments of the program were modified before being incorporated in the final draft of the programed textbook which, along with the accompanying teacher's manual, is also located in the appendices.
