Mathematics is a foundation subject within Computer Science which students continue to find challenging. Technology-enhanced learning pedagogies provide opportunities to improve educational learning outcomes, supporting dialogue and best practice. Research conducted over a three-year period at National College of Ireland's "Introduction to Mathematics for Computing" module with different cohorts investigated flipped and traditional pedagogy and flipped and traditional pedagogy with retrieval practice. The flipped classroom environment had a positive impact on student learning, and that effect was enhanced in a subsequent cohort by combining flipped classroom with retrieval practice. Maximizing performance in the practice tests, completing two to three practice tests and leaving a retention interval of 15 to 21 days optimised student learning outcomes. Future work will investigate the application of the Practice Testing Learning Framework with larger study sample sizes and extend the range of treatment topics in other domains.
