Based on a project involving selected teachers from various vocational service areas, this teaching guide presents the 12 most frequently used strategies of teaching used in the modular approach as determined by those in the project. The brief individual description of each strategy includes notes on its strengths and weaknesses, instructions or guidelines for its use, and, in some cases, lists of sources of additional information or materials. The 12 strategies are (1) assignment sheets and job sheets, (2) demonstration, (3) field trip, (4) films and filmstrips, (5) formal and informal lectures, (6) oral discussion, (7) projects, (8) resource persons, (9) role-playing, (10) shadowing, (11) tapes, and (12) transparencies.
