Investigating the Effect of Interface Scaffolding and Example Design on Learning and Performance in a Code-Tracing Tutor

Jay Brandon Jennings

Abstract: A foundational programming skill is code tracing. It involves simulating how a computer executes programs by tracking variable values and flow of program execution. Learning this skill is challenging and so research is needed to identify effective forms of assistance. This dissertation involves the design and evaluation of a computer tutor, called CT-Tutor.The tutor provided assistance for code tracing through interface scaffolding during code tracing as well as worked examples. The tutor was evaluated in thre… Show more
