The purpose of this study was to develop a course of study on Plane Geometry for the 8th grade, based upon the Instructional Systems Analysis technique. The systems model used was that developed by Bartel.The entire study involved identifying, selecting, and sequencing learning tasks. An elaborate review of resource materials on Plane Geometry yielded one hundred and fifty-five related tasks.The instrument developed to gather pertinent data had two parts to it. Part one contained seventeen items relating to the personal profile of the respondent. Part two consisted of the one hundred and fifty-five identified, verified, and correctly stated manipulative tasks. The tasks were grouped into two broad divisions. Each respondent rated each task on a 3-point scale according to the level of instructional importance he/she judged the task(s) should receive. A rating of 3 represented the highest level of importance; 2, average; and 1, least.The survey utilized the services of sixty-eight Nigerians currently on the Technical Teachers Training Program (TTTP) in the U.S. Information regarding the institutions and population of Nigerians on the program was obtained from the Training and Development Program (TDP) office in Washington, D.C. From the list of thirty-two possible institutions, twelve institutions met the criterion for participation.A Five-Interval Sampling Technique (FIST) was used to select subjects from the participating institutions. This gave the researcher a possible seventy subjects. Each subject's participation was purely voluntary. Thus the 73.6 percent return was considered satisfactory.The interpretation of data involved two analyses. Analysis one dealt with biographical information on each participant. The second analysis computed the summary of task ratings on the one hundred and fifty-five instrument items.Selection of tasks for inclusion in the course of study reported in this study was based on the judgments of the subjects. Higher mean values were used as the basis for selection. Overall, thirty top tasks were selected and sequenced for the purpose of the course of study under investigation.
