This distributive education performance-based instructional unit is designed to help students understand the system of physical distribution and to act as an aid to guiding students in preparing for future careers in the transportation industry dealing with the retail, wholesale, and service occupations. (Physical distribution involves the moving and storage of goods, services, and people.) This guide includes seven lesson plans, each based on 55-minute class periods. The lesson plans cover the following information: occupations in transportation pertaining to marketing and distribution; activities involved in warehousing and merchandise-handling; basic types of carriers used in transportation; the appropriate steps necessary to transport a product from a producer to the retail store; and the requirements necessary to enter specific transportation industry careers dealing with retail, wholesale, and service occupations. Each lesson plan includes most of the following items; information sheets, assignment sheets, transparency masters, key and answer sheets, and teacher reference sheets. A list of terminal and enabling objectives and a pre-assessment instrument and key precede the lesson plans. Optional activities, a bibliography, a post-assessment instrument and key, and a unit evaluation are included at the end of the unit. (BM)
