dc.description.abstract The purpose of the project is to generate and evaluate a programmed instructional unit on acid-base theory to be used in a high school chemistry course. The program unit will consist of ninety-five different frames in which the theories proposed by Arrhenius, Bronsted-Lowry, and Lewis are discussed. Other concepts to be developed are: naming acids, bases, and salts; concentration units- molarity and normality; acid-base dissociation constants; hydrolysis; pH; and titrimetry. The study also will include laboratory exercises in which the student is able to study independently and discover for himself some of the physical and chemical properties of acids, bases, and salts. Problem solving frames related to the concepts previously mentioned also are included.The program will be evaluated in terms of; achievement gain, attitude of the individual, sex of the individual, cognitive style, attitude toward science, PSAT scores, and I.Q. on the basis of pretest and posttest scores on the various measuring instruments. Each effect will be tested on the basis of a null hypothesis generated for each factor measured. Several single factor analyses of variance and correlation analyses will be used to analyze the data.The data for the evaluation of this program unit will be obtained from students enrolled in the chemistry classes at Alexandria-Monroe High School, Alexandria, Indiana. The students are randomly assigned to the classes by guidance personnel.
