Analysing the API learning process through the use of eye tracking

We conducted an exploratory study in which participants had to acquire knowledge of unfamiliar application programming interfaces (APIs) in order to complete two programming tasks. Eye tracking was used to monitor participants' attention throughout the study. We analysed the learning process using the COIL model, which includes three stages: Information Collection, Information Organisation and Solution Testing. Using this model, we describe patterns in the sequences of actions derived from the data. We discuss whether the Solution Testing stage has two distinct functions: constructing the solution and gathering information simultaneously. This would be an exploratory Solution Testing Stage. In addition, the use of eye tracking provided further insight into the API learning process.
