Screencasting makes it possible for teachers and students to create video presentations of slideshows, websites, documents and other items with voice-over narration, including the option of embedding one's webcam in the video.
Screencasts often show viewers how to use certain software applications, and many teachers and students make screencasts by recording a multimedia slide show, annotating over the slides as they speak. You can watch an example math screencast from Khan Academy by clicking here.
Screencasts can be embedded or linked in Canvas or Google Classroom, making it easy for students to see and hear lessons.
