"Teaching Sociology" recently published several articles dealing with the use of computer-assisted pedagogical techniques. Many authors assess the effectiveness of specific computer-assisted instruction (CAI) forms by examining either student performance or student course evaluation. Typically one group uses some form of CAI while the other does not. By not comparing these pedagogical techniques between different courses, previous studies do not focus on the types of courses where the use of CAI is more or less effective. This case study examines two different lecture-based courses comparing the use of a traditional, "chalk and talk" pedagogy with an approach complementing lecture through the use of computer-assisted slideshow presentation software. In order to see if the effect of using presentation software varies between particular types of courses, the author compares a substantive, descriptive course to a theory course presenting abstract material and asking students to apply these concepts to concrete examples.
