ABSTRACT
We apply APT to a large-scale study of the effectiveness of First Principles of Instruction within the online Indiana University Plagiarism Tutorials and Tests (IPTAT). We begin by illustrating two typical cases of learning journeys: Sam and Melinda. We next summarize the results from our Big Study of over 936,000 learning journeys during 2019 and 2020. We demonstrate how we found that, on average in each learning journey, successful students were nearly four times more likely to utilize unique parts of IPTAT which were designed with First Principles of Instruction, when compared with unsuccessful students.
