We'll get to work

We'll create your course, including any and all sub-sections and lab groups required. We can also onboard all of the faculty and staff who need access. Stemble supports the inclusion of any number of course coordinators, instructors, TAs, split among any number of sections. 

We can also build online versions of your tests and assignments, including our randomization and intelligent grading and feedback technology. Additionally, you can feel free to browse our growing library of content for chemistry to create any number of assignments for your various cohorts of students.

Deploy your course whenever you're ready

Once you deploy your course, we'll invite your students to the platform and get them started. You'll be able to deploy your assignments whenever you wish and watch your students interact with the content in real-time.
