There is no time for a make up session. You are to spend 5 hours exploring educational resources on the internet. Concentrate on mathematics and science education resources. In addition you must write a 3-5 page paper analyzing the congruence or lack thereof of practices in schools compared with the ideas put forth in your classes at the University. If you do 25 hours of observation the paper is waived.
Attendance is important.
I do take attendance each class session. I reserve the right to penalize the final grade of anyone who is consistently late. I will extend a due date on an individual basis if something happens and you need extra time. I expect you to arrange this in advance. Nothing can be turned in late without prior permission.
