Digital Ink: In-Class Annotation of PowerPoint Lectures
Anne E. Johnson · Journal of Chemical Education · 2008
Digital ink is a tool that, in conjunction with Microsoft PowerPoint software, allows real-time freehand annotation of presentations. Annotation of slides during class encourages student engagement with the material and problems under discussion. Digital ink annotation is a technique suitable for teaching across many disciplines, but is especially useful for courses that rely on visual materials rather than text and is a good substitute for chalk boards and overhead projectors.
