Intended to follow an introductory unit, this revised unit is one of several being prepared as part of a geography course based on a settlement theme provisionally planned for tenth grade students and requiring approximately four weeks. An extensive tryout conducted in 1965 in four areas of California, Illinois, Ohio, and New Jersey involved 47 teachers and approximately 2200 students in the formative evaluation. Teachers administered the School and College Ability Tests (SCAT), form 2A, and also the Introduction to Geography and Intra-Urban Unit Tests as pre-tests and post-tests. Students and teachers completed questionnaires on their impressions of the unit, as summarized in an appendix, responding positively. On the average, from the pre-test to the post-test of the Intra-Urban unit test, there was a mean increase of 19 per cent in the number of students answering the questions correctly. Recommendations for improvement are that a greater variety of readings be included, more attention be focused on local communities, some activities need to be dropped because the unit is too long, and that the unit test, class discussions based on unit readings, and student exercises be examined and analyzed.
