The methodology used in the evaluation of this unit is the same as that described in SO 000 433. The total number of students in the trial was about 2,100 seventh through twelfth grade students. The version of the unit used included nine activities, three of which were optional and designed to reinforce and supplement the required activities: 1) Political Territoriality; 2) Political and Administrative Districts of the City; 3) Scatter Diagrams of the Political Hierarchy and its Territorial Framework; 4) The Game Called "Section"; 5) The Location of the Massachusetts State Medical School; 6) Reapportionment and Gerrymander Exercise; 7) The United States-Canada Boundary Dispute; 8) The Changing Function of Boundaries in the European Common Market; and, 9) Designing a World Political Map. In conclusion, test results and student and teacher comments indicated that the subject matter of the unit was somewhat complicated for the majority of the students, and that it was too long. However, the role-playing activities were very well received (activity 4 and 7) indicating, in addition, that they would like more in this unit and the other units. The unit test, evaluation forms, and statistics are appended. See SO 000 433 for a list of the related reports. (SBE)
