So Yoon Yoon, Ph.D., is a post-doctoral research associate at Texas A&M University. She received her Ph.D. and Educational Psychology with the specialties in Gifted Education and Research Methods & Measurement, respectively, from Purdue University. Her work centers on the development and validation of instruments, particularly useful for P-16 STEM education settings (e.g., the Revised Purdue Spatial Visualization Tests:Visualization of Rotations [Revised PSVT:R], the Teaching Engineering Self-efficacy Scale [TESS], the Student Attitudinal Success Inventory [SASI]), the evaluation of engineering teacher professional development programs, and the investigation of P-16 students’ spatial ability to understand its association with their academic performance and talent developemnt in STEM fields.

Validation of the Extended Student Attitudinal Success Inventory (e-SASI) for Engineering Students (Research Paper)As low student retention rates in engineering programs in the United States become a threat tothe effort to increase the engineering workforce, various approaches have been utilized toinvestigate the putative factors that may contribute to attrition of engineering students.Traditionally, indicators of students’ pre-college academic performance, such as high schoolgrade average points (GPAs) and scholastic aptitude test scores (e.g., the SAT and the ACT),have served as main criteria to determine acceptance to engineering programs because of theirassumed predictive validity of academic success in college. However, recent studies haveprovided evidence on the predictive power of non-cognitive attributes over cognitive measures ofstudents in retention and their future academic performance.This study describes a validation procedure for the extended version of the Student AttitudinalSuccess Inventory (SASI) to assess engineering students’ multifaceted non-cognitive attributes.Originally, the SASI consisted of 168 items that originated from existing instruments and weredeveloped by a group of researchers at a Midwestern university based on theoretical frameworksfrom literature. The nine constructs measured by the SASI are academic self-efficacy, academicmotivation, leadership, metacognition, major indecision, deep learning style, surface learningstyle, teamwork skill, and expectancy-value, each using a five-point Likert type scale. However,with increasing research evidence about other constructs relevant to students’ collegeperformance and retention, the SASI was extended to include 246 items by adding items aboutgoal orientation, implicit beliefs, intent to persist, social climate, and self-worth. As the extendedSASI (e-SASI) contains many constructs and items, this study aims to restructure the e-SASI tokeep only essential constructs and items through psychometric approaches and provide reliabilityand validity evidence of the e-SASI.In 2007, more than 1,700 students, who enrolled to attend a first year engineering (FYE)program at the Midwestern university, were invited to respond to online surveys during thesummer before their start of the program. Among them, 1,182 students (NM = 943 [79.8%], NF =239 [20.2%]) completed the e-SASI. An initial exploratory factor analysis was conducted. Tofinalize the items and the factor structure of the e-SASI, a confirmatory factor analysis will beapplied on a new data set collected from 1,695 FYE students in 2008. As students’ non-cognitiveattributes have gained more attention in academic performance and retention studies in highereducation, we expect that the e-SASI can be used as a sound and all-round instrument to measureengineering students’ non-cognitive attributes for various research and education purposes.
