An Experimental Evaluation of Programed Instruction as One of Two Review Techniques for Two-Year College Students Concerned with Solving Acid-Base Chemical Equilibrium Problems.
Sharon, Jared Bear
The major purpose of this study was to design and evaluate a programed instructional unit for a first year college chemistry course. The topic of the unit was the categorization and solution of acid-base equilibria problems. The experimental programed instruction text was used by 41 students and the fifth edition of Schaum's Theory and Problems of College Chemistry was assigned to the remaining 40 students in the sample. An evaluation was made related to student performance. Three criterion measures were administered during the investigation. Means on all were adjusted by analysis of covariance. The covariate was student test average achieved in Chemistry I prior to the experiment. Variables included lecture hour, use of materials subsequent to the experiment, student ability, and ethnic origin. The performance of the experimental group was significantly better (.01 level) than that of those students using the problem solving manual. Programed instruction was of significant benefit to all students, regardless of their previous performance in the course or their ethnic origin. (Author/EB)
