One of a series of eleven curriculum manuals which cover the four transportation topics of public transportation, transportation and the environment, transportation safety, and bicycles for elementary, secondary, and adult levels, this manual covers the public transportation topic for grades 9-12. It contains forty-nine learning activities grouped into nine mini-units. Each mini-unit consists of a lesson plan component and an individual learning activities component. The first mini-unit provides a survey of issues related to public transportation; the rest are as follows: developing skills to identify and use public transportation, learning to make choices among different transportation modes, learning how to promote the use of public transportation; learning to seek redress of grievances over public transportation service, learning to evaluate the financing of public transportation, examining groups with travel problems, learning about the history of public transportation, and research projects on public transportation. A final section offers additional activities that may be used to evaluate or supplement evaluation of an activity or mini-unit. Also included are references for further study resources, suggestions for integrating the units into other subject areas, and for reproduction of role profiles, game boards, maps, and other distributable materials. (A curriculum guide, CE 014 028, is also available for use with the manuals.) (TA)
