This teacher's guide is designed to accompany the competency-based education student material for welding (available separately through ERIC--see note.) It consists of five sections and three appendixes. Section 1 discusses the uses of the welding competency-based curriculum along with its purpose and design. Definitions of terms used in the guide are provided in section 2. The third section contains a listing of the use of competencies by job title. Section 4 outlines the welding curriculum table of contents. The fifth section (the bulk of the guide) consists of teacher evaluation aids (task tests, module tests, and unit tests and answer keys to both the tests and the exercises included in the student curriculum package). The first appendix contains data and information on tasks currently performed and equipment used, as determined from the validation survey. The second and third appendixes include lists of additional tools and equipment used and tasks performed by respondents to the survey. (MN)
