Developed as part of a National Workplace Literacy Program, this lesson focuses on terms and mathematical operations associated with Statistical Process Control (SPC) in the foundry industry. With appropriate assistance and preparatory work, workers testing between grades 4 and 9 on the Test of Adult Basic Education Locator should be able to use the lesson. The individualized lesson is intended to supplement small-group SPC activities. It teaches terms and mathematics used in quality control at Bodine-Robinson and Robinson Foundry. Reading material is followed by questions that ask about the instructional material. Some terms that are covered include key characteristic, specification, aim, and control limits. Mathematics areas include adding and subtracting SPC measurements, adding and subtracting decimals, figuring averages, and figuring ranges. A true-false quiz on the material is provided. (YLB)
