Development Of Psychometrically Validated Standardized Test Instruments For Outcomes Assessment In Experiential Engineering Education

Abstract

There is a major trend in engineering education to provide students with realistic hands-on learning experiences. This paper reports on the results of work done to develop standardized test instruments to use for student learning outcomes assessment in an experiential hands-on manufacturing engineering and technology environment. The specific outcomes targeted for assessment are those defined under the MILL (Manufacturing Integrated Learning Laboratory) Manufacturing Competency Model. In a unique feature aimed at experiential learning, the test instruments incorporate the use of a physical manipulative to evaluate attainment of particular hands-on skills. The resulting standardized tests have been subjected to extensive psychometric analysis. The results of the analysis indicate excellent structure of the test instruments. The test instruments have shown high levels of stability, internal consistency, and reliability. These tests can be used as instruments for outcomes assessment to help document attainment of targeted learning outcomes for program assessment, accreditation, and other assessment purposes.
