Good question Grannicus. The purpose of the playlist is two fold.
First of all it is a way for you to collect interesting lessons, sort of a way to flag things of interest. These may be lessons that you have studied, and want to get back to, or lessons that you saw while searching the library and would like to study. You might have a Playlist called My Favourites for example, or a Playlist called Spanish History or the European Debt Crisis. You would create these playlists for yourself. You can even put the same lesson in different playlists.
The second purpose of the playlist is to help other learners. If you share your playlist of Favourites, or Spanish History, this may interest other learners. If you are a tutor, you may want to collect articles that you think are appropriate for learners of a certain level. Here again you can include the same lessons in different Playlists. Aaron’s beginner English Course could be a playlist, or Aaron’s Beginner Spanish Course for that matter, or whatever you want. If you share these and if others like them, these will be brought to the attention of other learners on the Recommended Playlist List in the Learn page. This is a great way for learners to help each other find appropriate, interesting and meaningful content in the library.
To create a playlist just start by selecting a lesson you want to add to a playlist. Click on the little arrow beside Open and from the drop down list select Add to Playlist. You will be asked to name the playlist and away you go. We hope people will create a lot of playlists, for themselves and to help others.
