Online courses and tutorials help the user in learning like using software, video game, or a lesson. In online tutoring, the students and the teachers are at physically different locations, connected to each other via Internet. Online learning has many benefits. It provides freedom to the learner to learn at their convenient location, convenient time and at their own pace of learning. Also, there is no discrimination of age, caste, gender, background, or the qualification of the learner. The tutorials may be enriched with audio and video information, which makes learning more enjoyable and attractive. Also, tutorials and tests are available for almost all topics, sometimes in regional languages also.
The tutorials may require different kinds of interaction with the user, for example,
● Video/slide tutorials where the video or slides of lectures are available. The learner can visit the site and view the tutorials.
● Interactive tutorials require the user to follow the instructions, perform the desired action and get a feedback.
● Webinars are real time lectures, where users participate in the lecture, may ask questions, and get their queries answered.
