I teach a Grade 11 Functions class, but this relates to basically all grade levels.
Khan Academy (discussed in Is Khan academy really good?) is a resource often being used by students as extra help, catchup for missed work, etc. etc. Would it be a good policy for me to post links to each topic on Khan Academy on my class webpage, so that students will use it to help them review and catchup, or will this encourage students to pay less attention in class and/or miss classes and extra help, since they know that they have a teacher-sanctioned backup?
(Please help me with the tagging/formatting, as this is my first ME.SE question.)
