In the third edition of the basic text, which deals with the methodology of preparing courses of study in industrial arts and vocational education, the title and content have been modified to include technical education. The authors stress the importance of the teacher's ability to organize instructional material where manipulative processes are involved; performance activities require analysis to identify appropriate work experiences, and manipulative operations require a certain sequential order of performance, which means that the teachable content must have a logical and methodical order. The practices and principles described in the book are aimed to help the teacher meet these goals. The first several chapters of the text establish a groundwork; they are followed by chapters which prepare the teacher to establish specific course objectives: carry out an instructional analysis; analyze a course for its basic operations; select the jobs, projects, or problems; arrange operations and work activities in an instructional order; select the related information for a course; analyze operations and related information; and assemble the course of study. The concluding chapters deal with instructional practices. (Author/AJ)
