Using Stemosphere
Study and practice
Stemosphere provides lessons and practice questions for independent study. Use learning materials alongside your course requirements. Completing a lesson records that you finished reading it; it does not certify mastery or award a qualification.
Practice results
Numeric and multiple-choice responses can receive automatic marks. Written responses are saved for comparison with a model solution. A practice result is feedback on that response, not an official assessment.
Your account
Keep your sign-in account secure. Use your own account for your learning records. Do not attempt to access another learner’s private information, change published content without authorization, or interfere with the website.
Learning materials
Use the lessons and diagrams for your own study. Do not republish materials unless you have permission from their rights holder. Available lessons and questions may change as content is corrected and reviewed.
Availability
Some topics do not yet have lessons or questions. AI tutoring and website contact submission are not currently available.
