The effect of PSpice software on Cal Poly students' ability to learn electrical engineering concepts formed the basis for this study. Usability testing of nine subjects investigated this relationship through two surveys and a series of observed engineering tasks.
It was discovered that students in this study approached engineering problems differently based upon their identified learning styles. Software models that did not reflect real-world counterparts confused users.
Overloaded dialog boxes, poor feedback, and difficult-to-discover 
   features all frustrated users in this study. When the software did not meet 
   user goals, use of the product was adversely affected. Finally recommendations 
   were made as to how knowledge of user learning styles can improve the design 
   of future user interactions and how software impacts student learning at universities.
