Comparisons in College Biology Achievement Between the Audio-Tutorial and Conventional Methods of Instruction for Non-Science Majors.
Grobe, Cary H.
The audio-tutorial (A-T) method of teaching biology at the University of North Dakota was studied among 79 subjects during the Fall term of the 1969-70 academic year to determine its effectiveness in comparison with the conventional method. Thirty-eight students were assigned randomly to the A-T group and 41 to the control group. All subjects were given the "College Entrance Examination Board Advanced Placement Exam in Biology." After completion of the course, a posttest was administered to both groups. The population sample was further analyzed into subgroups on the basis of additional data consisting of their aptitude, science background, and secondary-school size. Statistical results showed the absence of significant difference in achievement between the two groups. College student's aptitude, secondary-school size, and science background did not contribute significantly to the prediction of college biology achievement under either the A-T or the conventional method of instruction.
