Problem and Motivation: Testing accounts for 50% cost of software development. Because of the necessity of testing, educators are including more and more software testing[1] in programming [2] and software engineering courses [3, 4]. Current classroom assessment systems (e.g.,Web-CAT, ASSYST, Marmoset) use code coverage to evaluate how well students test their own code. Code coverage measures t...

The purpose of the study was to investigate the impact of an experimental online learning tool on student performance. By applying cognitive load theory to online learning, the experimental tool used was designed to minimize cognitive load during the instructional and learning process. This tool enabled students to work with programming code that was supplemented with instructor descriptions an...
