A Meta-Analysis of Selected Advance Organizer Research Reports from 1960-1977.
Kozlow, Michael James
The purpose of this meta-analysis of 77 advance organizer research reports was to identify characteristics of the experimental settings and materials that had relationships with the treatment effects obtained through the use of advance organizers. The dependent variables used to represent the treatment effects were the t-statistic for the difference between means and the probability level of significance. The independent variables described characteristics of the sample, treatment administration conditions, type of subject matter, quality of the research procedures, and characteristics of the AO and learning materials. The distribution of the computed t-statistics indicated a tendency for AOs to show facilitative effects. The following conclusions were based on the correlations between independent and dependent variables. Some of the reported facilitative effects of AOs may have been due to the possible contribution of the AO alone to answering the test questions or to an inequality of study time for the treatment groups. Student inability to understand the AO information may account for some of the non-significant findings. Comparative AOs may be more effective than expository ones. AOs may be more effective for classificational concepts and for students at higher grade levels. A list of guidelines for future AO research is included. (JK)
