Computer-Aided Drafting 901 FOREWORD Basic Drafting: Book Two is the second volume of a series of drafting materials being produced by the Mid-America Vocational Curriculum Consortium. This book and Basic Drafting: Book One comprise the basics necessary to be employed in a drafting occupation. Areas of specialization such as Mechanical Drafting and Architectural Drafting are being written as supplements to be used with this book. t The success of this publication is due, in large part, to the capabilities of the personnel who worked with its development. The technical writers have numerous years of industry as well as teachino/and writing experience. Assisting them in their efforts were committee representatives who brought with them technical expertise and experience related to the classroom and to the trade. To assure that the materials would parallel the industry environ- ment and to be accepted as a transportable basic teaching tool, other organizations and industry representatives were involved in the developmental phases of the manual. Apprecia- tion is extended to them for their valuable contributions to the manual. This publication is designed to assist teachers in improving instruction. As this publi- cation is used, it is hoped that the student performance will improve and that students will be better able to assume a role in their chosen occupation. Every effort has been made to make this publication basic, readable, and by all means usable. Three vital parts of instruc- tion have been intentionally omitted: motivation, personalization, and localization. These areas are left to the individual instructors who should capitalize onthem. Only then will this publication really become a vital part of the teaching-learning process. Instructional materials in this publication are written in terms of student performance using measurable objectives. This is an innovative approach to telching that accents and augments the teaching/learning process. Criterion referenced evaluation instruments are provided for uniform measurement of student progress. In addition tc evaluating recall information, teachers are encouraged to evaluate the other areas including process and product as indicated at the end of each instructional unit. Itis the sincere belief of the MAVCC personnel and all those members who served on the committee that this publication will allow the students tobecome better prepared and more effective members of the work force. If there is anything that we can do to help this publication become more useful to you, please let us know. Merle Rudebusch, Chairman Board of Directors Mid-America Vocational Curriculum Consortium 6 Is v U PREFACE Basic Drafting: Book Two is the second of two publications designed to include the content necessary for employment in an entry level drafting occupation.Originally intended as only one volume, the separation of Basic Drafting into twobooks was done in order to reduce the size of the materials. The result is two books that are shorter, more handy to carry, and much more convenient to work with. In a time when educational costs continue to rise, a lower priced text will be welcomed by teachers and students alike. But more than that, curriculum materials presented in such a comprehensive size will be easier to adapt to speciality programs with industry and adult education. There has never been a MAVCC publication in which we failed to request that teachers and educators let us know how the curriculum is working out in the classroom. Teacher ;esponse to date has helped make the MAVCC format the mostsolid in vocationaltechnical education, and this new, comprehensive publication of Basic Drafting should prove once more that as MAVCC continues to publish, we also continue tolistenand respond.
