The objective of this "Preparing for Tomorrow's World" (PTW) program module is to help students (grades 7-8) gain insight into coastal issues and confront moral dilemmas which relate to those issues. PTW is an interdisciplinary, future-oriented program incorporating information from the sciences/social sciences and addressing societal concerns which interface science/technology/society. The program promotes responsible citizenry with increased abilities in critical thinking, problem-solving, social/ethical reasoning, and decision-making. The module is comprised of two parts: estuary marshes and activities along the coast. Each is introduced by a filmstrip and followed by student activities--written exercises, role-play simulations, and dilemma discussions (available in the guide as student handouts). Dilemmas, brief stories in which two or more moral/ethical conflicts must be resolved, are accompanied by questions to stimulate thinking and/or generate discussions. In addition to student handouts and instructional strategies, the teaching guide contains module overview, chart indicating moral issues (as identified by Kohlberg) in each dilemma, suggested time schedule, bibliography, and sources for supplementary materials. The module may be used as a separate unit of study, as a mini-course, or incorporated into existing curricula where appropriate. (JN)
