Abstract: Performance support systems provide knowledge and tools for solving problems within complex systems. This paper investigates the use of performance support systems as learning tools: that is, as sources of knowledge to enhance understanding of problems embedded within complex systems. The study contrasts two different approaches to performance support in conducting engine diagnostics in a military setting. The results of an experiment employing pairs of learners show that one of these approaches – the LockTel Framework-enhances learners| understanding of the engine system, while time constraint reduces understanding. Implications of this study for the design of performance support systems for learning are discussed.

Keywords: learning support; learning environments; problem solving; engine diagnostics; performance support; complex systems; learning tools; knowledge sources; military training; LockTel Framework; time constraints; understanding; system design; US Army; USA; United States; technicians; military vehicles.
