These instructional materials were developed and designed for secondary and adult limited English proficient students enrolled in machine tool technology courses. Part 1 includes 24 lessons covering introduction, safety and shop rules, basic machine tools, basic machine operations, measurement, basic blueprint reading, layout, and bench tools. Each lesson contains student performance objectives, procedures for the students to follow in progressing through the lesson, information sheets illustrated with line drawings, and references and lesson summaries as needed. These competency-based lessons may be used as a main text, as supplements to other textbooks, or as the basis for a prevocational course in manufacturing trades. (A corresponding student workbook and instructor's manuals are available.) (KC)
