Thesis: S.B., Massachusetts Institute of Technology, Department of Mechanical Engineering, February 2017., Cataloged from PDF version of thesis., Includes bibliographical references., The aim of this investigation is to design educational project enclosures for engineering students at MIT that utilize the laser-cutter, CNC "DiWire" wire bender and various other mechanical engineering tools. Introducing students to the laser-cutter and wire bender gives them hands-on experience with some exciting mechanical tools for fabrication to supplement their courses in electrical engineering. The key objective of this investigation is finding a cheap, safe, professional-looking, easy-to-manufacture setup that teaches students the desired concepts and gives flexibility for Professor Leeb to integrate novel engineering projects into his classes. The second section of this design project is the creation of a soldering iron holder made using components bent on the DiWire. Many design iterations are carried out before settling on the final design and material choice. The soldering iron holder is then incorporated into a larger electrical engineering project. This larger project is a speaker that students put together and house in a special enclosure., by Larkin V. Sayre., S.B.

An instructor's manual and student activity guide on forestry seedlings are provided in this set of prevocational education materials which focuses on the vocational area of agriculture. (This set of materials is one of ninety-two prevocational education sets arranged around a cluster of seven vocational offerings: agriculture, home economics, distributive education, health occupations, world of work, trade and industry, and office occupations.) The instructor's guide is organized into the following elements: title of activity, duration of activity (three to eleven periods), activity goals, eleven instructional objectives, related vocational clusters, and activity implementation (description, materials needed, safety considerations, teacher preparation prior to class, during the class, follow-up activities, answer key to student check point activities, and masters for duplication [e.g., check sheets, sample application for ordering seedlings]). The student activity guide provides step-by-step instructions (narrative and illustrations) for completing each instructional objective (e.g., write an application to order seedlings, identify five rules for seedling planting, use an increment borer). At the end of each set of instructions is a student check point (evaluation activity). Occupational descriptions for a forester aide, fire ranger, forest worker, and tree planter conclude the document. (JH)
