Types of distance education

  • Recording type

 The recording type is an online lesson in which pre-recorded videos are distributed.Students watch the video from websites where the video is uploaded.

Since it is not a live stream, it is possible to repeatedly listen to the missed part or pause when taking notes.Also, basically, unless the video is deleted or made private, it is on the website, so you can watch it at your own timing.

  • Live delivery type

 The live distribution type is an online lesson in which it is distributed in real time using a video distribution tool or the like.Since it is delivered in real time, it will start at a fixed time.

It seems that the number of educational institutions that provide online lessons by live distribution is increasing because it is easy to do.

  • Bidirectional type

 The interactive type is an online lesson in which the lesson progresses in real time in the same way as live distribution. Applications such as "ZOOM" and "Skype" are often used.

The difference from live streaming is that you can see each other's faces and students can ask questions by chatting.Since the instructor and students can communicate with each other, it will feel as if they are actually taking classes face-to-face.[2]
