Evaluating the use of problem-based video podcasts to teach mathematics in higher education

Problem-based video podcasts provide short, web-based, audio-visual explanations of how to solve specific procedural problems in subject areas such as mathematics or science. A series of 59 problem-based video podcasts covering five key areas (operations with functions, solving equations, linear functions, exponential and logarithmic functions, and trigonometric functions) were created as self-study tools and used by 288 higher education students to acquire pre-calculus skills over a three week period. The results indicated that a majority of students used the video podcasts frequently, rated them as useful or very useful, viewed them as easy to use, effective learning tools, and reported significant knowledge gains in pre-calculus concepts.

► A set of 59 problem-based video podcasts was designed to help students improve their pre-calculus knowledge.
► Two-thirds of the students viewed over 4500 video podcasts during a 21 day period.
► Students used video podcasts because step-by-step, visually based explanations helped them learn when and how they wanted.
► Students rated problem-based video podcasts as useful, easy to follow, and effective in helping them understand new material.
► Students also reported significant pre-calculus knowledge gains as a result of using video podcasts.
