ab: Summary: Basic calculus skills that are prerequisites for advanced
mathematical studies continue to be a problem for a significant
proportion of higher education students. While there are many types of
revision material that could be offered to students, in this paper we
investigate whether short, narrated video recordings of mathematical
explanations (screencasts) are a useful tool to enhance student
learning when revisiting prerequisite topics. We report on the outcomes
of a study that was designed to both measure change in student
performance before and after watching screencasts, and to capture
studentsâ€™ perception of the usefulness of screencasts in their
learning. Volunteers were recruited from students enrolled on an entry
module for the mathematics Master of Science programme at the Open
University to watch two screencasts sandwiched between two online
calculus quizzes. A statistical analysis of student responses to the
quizzes shows that screencasts can have a positive effect on student
performance. Further analysis of student feedback shows that student
confidence was increased by watching the screencasts. Student views on
the value of screencasts for their learning indicated that they
appreciated being able to watch a problem being solved and explained by
an experienced mathematician; hear the motivation for a particular
problem-solving approach; engage more readily with the material being
presented, thereby retaining it more easily. { }The positive student
views and impact on student scores indicate that short screencasts
could play a useful role in revising prerequisite mathematics.
