These authors offer a step-by-step approach to developing and using ITUs to help K-12 students acquire the knowledge and develop the problem-solving skills required for today's changing—and challenging—times. Revised to encompass significantly more material on curriculum standards, scoring guides, and the relationship between the interdisciplinary thematic unit approach and professional education tests, the new edition of this popular text again addresses the content, technology, diversity, and classroom management of ITUs.
