LECTURE SLIDES WITH RECORDED VOICE

Many of us teachers already use computer management systems, such as BlackBoard, to post lecture PowerPoint slides. They may be either incomplete slides (skeleton) posted previously to the class so that students can complete them as they hear the explanations in the lecture or ink annotated slides posted after the class is over with details of the explanation. In my experience, the next step to this practice is to post lecture notes with embedded voice.

There are several programs that enable voice recording. In my presentation I will show how Jing, a free software simple to use, can accomplish that objective. The process consisting of recording several little videos and then incorporating them all in a PowerPoint presentation will be fully explained.

This approach to e-teaching/learning is useful when students want to hear again and again an argument or the steps of a mathematical derivation. Whether they are unable to be in class due to sickness or family responsibilities, or whether students want to review the material they heard in class, voice recorded lectures can be extremely useful.

Last but not least, this is surely an easy first stepping stone for those teachers who are preparing to offer on-line courses.
