This course in intended for anyone who finds it attractive.
As it deals with assuming personal responsibility for education, it’s unlikely to appeal to students who are too young to appreciate the need to: articulate authentic goals for their learning, or consider their influence on others and assume some responsible for it. Broadly speaking, this level of maturity begins in adolescence. (Keep in mind that several of the Discussion Topics deal with the readiness of students to handle responsibility, and whether we are offering it when we should.)
If you’re an adult considering this course for a young person, you should review all the course documents and decide whether they are fit for it. To introduce the course to a student, send them a link to the homepage, which should direct them to read through the Course Material. At this point the best test of whether a student will benefit from the course is whether they a) read these documents, and b) choose to give the course a chance.
By all means, be as persuasive as you can in your advocacy (while respecting the student’s autonomy). Though I’ve done my best to present the value of the course in these introductory pages, your own sincere words are likely to be significant. Whether or not a young person is ready to take the course, they can still benefit from it through you, as you work with the material and use its ideas in the ways you teach and learn.
