This guide describes development of the problem-based approach of GED as project. It is Volume 1 of a proposed four-volume series. Section 1 describes the concept of GED as project, thinking and problem solving, successful intelligence, and integration of content and skills. Section 2 covers GED as project implementation using learning projects and inquiry activities. It explains how the learning project focuses on a larger issue requiring multiple inquiry activities to achieve. Five phases of the inquiry process, a template to develop inquiry activities, are presented: identifying the problem; becoming familiar with the problem; planning, assigning, and performing tasks; sharing with others; and reflecting, extending, evaluating. Section 3, on teaching through facilitation, discusses facilitated learning as active learning, characteristics of effective facilitators, and facilitative style. Section 4 covers these assessment topics: a definition, methods, intake assessment, and disabilities. Section 5 lists tips to manage the GED as project classroom. Sections 6 and 7 provide sample inquiry activities for two learning projects: "The GED and You" and "The GED and You Revisited." Each inquiry activity follows the template described in Section 2. The inquiry activity instructions are in an instructor guide format; learner's instructions are in italics. The learners' version includes spaces for writing notes and answers. Appendixes include a list of 33 print, web, and video resources for use with GED 2002; sample individual action plans; and list of 11 references. (YLB)
