A Comparison of the Effects of an Advanced Organizer and/or Behavioral Objectives on the Achievement of Disadvantaged Biology Students.
Kahle, Jane Butler
The use of an advanced organizer (a generalizable, encompassing concept) prior to an individualized instructional sequence in a self-paced, audiotutorial learning format was accompanied by gains in individual unit achievement and in retention by disadvantaged biology students. Although behavioral objectives generally were shown to make no significant difference when utilized in the same manner as the advanced organizer, a significant increase in achievement occurred when they were used together. This increase might be attributed partly to the use of the behavioral objectives. A series of three audiotutorial units in genetics covering topics in mitosis, meiosis, and chromosomal abnormalities composed the instructional materials. During the course of the six-week experimental period, all subjects received audio tapes, study guides, visual aides, and tests. Achievement was measured by formative unit tests, a summative final test, and a summative retention test. (Author/BB)
