Research Strategies in Higher Education.
Semb, George
The present paper outlines two alternative strategies for evaluating teaching effectiveness. These are: (1) within-subject reversal designs, and (2) multiple baseline testing procedures. Each design is discussed in terms of its application to research problems in higher education. In reversal designs, the student is exposed to different teaching procedures during successive phases of a course. Changes in performance between treatments are analyzed, either on the basis of group averages or in terms of individual performances. The reversal design becomes even more powerful if a second group of students goes through the treatments in opposite order, thus counterbalancing the two groups for possible changes in difficulty across conditions. In the multiple baseline testing procedure, students are given a comprehensive examination before instruction begins, and at the end of each successive phase of the course. This allows the instructor to demonstrate that changes in performance are functionally related to specific teaching procedures introduced during each phase. Furthermore, it provides a continuous baseline measure over material that has been trained. Percentage gains over baseline levels can be used to measure differential effects of different teaching procedures. Similar to the reversal design, the multiple baseline design allows the researcher to make statements about the effects of each procedure on individual students. (Author/DB)
