Coursmos is a platform where teachers can upload their videos and create micro-courses. Each micro-course consists of up to 7 micro-lessons (online videos) and each micro-lesson lasts maximum 3-4 minutes.
The driving idea behind micro-courses is to engage learners in short-term courses which are more manageable than courses that last a long period and in that way they are more likely to stay focused for the entire lesson and learn at maximum efficiency.
While it is free to create a micro-course, it is up to the author to decide whether the micro-course will be freely available or whether learners have to pay to attend. All in all, Coursmos is a convenient tool for people who wish to share their knowledge through personally created videos, especially to those who want to get paid from it.
