Video tutorials can be viewed on computers through either DVDs or online streams, as well as mobile devices. Video tutorials help adult students save on transportation costs and commuting time. Video tutorials also allow students to access lessons from instructors who are well-known as specialists in their fields, but otherwise inaccessible to students due to distance, such as professors in foreign countries. These professors on video might add another dimension to the students learning in those fields that their local schools cannot provide.
The ability to pause, rewind, stop and play a recorded video tutorial from a DVD or online helps students replay important points that they need to remember, which is essential for memory retention in preparation for exams. In a live classroom, it's easy to miss what the instructor says at any given moment, but with a video tutorial, notes can be rechecked for accuracy. A lesson in video format allows students to focus in on specific segments, as well as play the information in its entirety.
Video tutorials offer a multidimensional experience that may combine charts, slides, photos, graphics, narration, screenshots, on-screen captions, music and live video. This allows students with different learning abilities to retain information in a method more suited to them. The more that tools are utilized in a video tutorial, the more ways a student has to focus on, comprehend and retain the information. Many of these multimedia aids might be too complex or time-consuming to regularly utilize in a physical classroom environment.
