Each summer since 1990, a select group of Pennsylvania high school students has taken part in the Pennsylvania Governor's School for Teaching (PGST), held at Millersville University. The school is dedicated solely to the profession of teaching and brings together sophomores and juniors who have expressed an interest in teaching as a career. This volume describes the first two years of PGST--its goals, program, and achievements. The following topics are covered: (1) evolution of the PGST including its rationale and funding information; (2) student recruitment and selection; (3) structure and staffing of the program--resident life counselors, support staff, special presenters, and the cooperative model of staff development; (4) program highlights, including reflective journals, teaching in the school-within-a-school, multicultural experiences, learning theories, teacher/learner pairs--action research, a model school project, and leadership projects; and (5) program evaluation by everyone involved in PGST (64 students, 22 staff, 16 Advisory Council members, 79 parents, and 30 mentor teachers in the students' home districts).
