Master subjects: Collaborative space for teachers

Create and modify custom resources with colleagues while keeping them separate from student work. 

A teacher can create unlimited subjects on Stile. A master subject can be used as a private, or collaborative, creative space simply by not enrolling students. Teachers participating in the master subject can copy lessons or whole folders of lessons into their own subjects to share with students.

Create a master subject in a few quick steps:

Create a new subject


Make a new subject on the home page and add something like [MASTER] or [EDIT] to its title, to make it stand out. (related: Create a new subject)

Invite Collaborators


Share the subject with colleagues so they can contribute. (related: Add a teacher to a subject)

Note: To share the lessons without allowing other teachers to contribute, share the lessons to the school library instead.

Don't invite students

Don't do it! This space is for creating and editing lessons before students work on them.

Start Creating

Select either Browse the Lesson Library or Create new lesson. If there are already resources in the subject then the latter option will be replaced with Create folder. Creating a new lesson will also create a new folder to contain it, titled New folder.


Rename the folder something short and descriptive by clicking the Edit button in the folder's dark grey header.

Keep track of changes


Especially if the subject is shared by multiple teachers, keep a diary in the folder's teaching notes of any major edits. An example entry may include the date, the editor's name, and a brief description of what was changed. Click the Edit button in the dark grey header to update the folder's teaching notes.

Copy resources into an active subject


Resources can be copied and pasted between subjects. When a lesson or collection of lessons is complete in the master subject, don't invite students. Instead, add the completed resources to a separate subject that is or will be populated with students. This will allow teachers to continue refining the resources in the master subject without the risk of overriding student work. (related: copy and paste resources across subjects)

Share lessons without collaborating

Resources shared to the school library are copies of the originals. Similar to the Stile Science library, teachers can add copies of the shared resources to their subjects and any edits they make will not affect the originals. Use the school library instead of adding co-teachers to the master subject if collaboration is not desired. (related: share to the school library
