Written from experiences at the May 1987 Writing across the Curriculum Summer Writing Institute at Indian Hills Community College in Ottumwa, Iowa, this collection of 14 essays describes methods of using writing as a learning tool across various disciplines. The 15 instructors attending the workshop represented the fields of technical communications, history, science, English, art, electronics, mathematics, computer maintenance, lasers, robotics, data processing, and drafting. The workshop was designed to examine current theory and research in writing instruction, methods of using writing in all subject areas, methods of fostering cooperation and cohesion in writing instruction among instructors of different subject areas, and the personal writing development of each instructor through peer writing group experiences. Essays from the workshop include: (1) "The Use of Philosophical Writing in History Courses"; (2) "A General Physics Laboratory Report on the Hydrogen Emission Lines and Bohr's Theory"; (3) "Journalizing Mathematics Assignments"; (4) "Teaching Language Effectiveness"; (5) "The Journal for Painting"; (6) "Writing and Computer Aided Drafting"; (7) "Using Writing in a Computer Course"; (8) "Workaday Writing in Mathematics"; (9) "Integrating Writing Skills throughout a High Technology Vocational Curriculum"; and (10) "Use of Student Notebook in Biology."
