The report detailed an experiment with 3 methods of instructing American Indian children in Taholah Elementary School (Quinault Reservation, Washington State). To assess the relative value of instructional methods in the school, 2 conditions had to prevail. The content of the lessons was to be unknown to pupils at all grade levels, and the content should be of general interest to the students. To satisfy these conditions, the study of the nature of cities was selected for its interest appeal. The 3 instruction methods were: (a) a method that relied totally on textual materials that the students have to read; (b) a method that required the text to be presented orally by the teacher with supplemental pictures; and (c) a visual presentation with large overheads followed by an oral teacher presentation. The experiment used a 3x3x3 design. The 3 dimensions--grade, concepts, and methods--were each divided into 3 parts. The 6 grades were divided into 3 groups: 3-4, 5-6, and 7-8. A total of 104 pupils were used in the experiment. Analysis of student achievement by the individual concepts across methods yielded an F-ratio which was not sufficiently large to be significant. The F-ratio on the central place concept was .15, on the special function concept .24, and on the break-of-bulk concept it was 1.1. (FF)
