ok, maybe everybody already knows this except me - sorry if it's not new news. I have always struggled with when to group my students homogeniously (spelling? sorry) and when to group hetrogeniously. (and I teach Language arts - I can't spell) I have asked other teachers their thoughts on this and have gotten vague answers or flat out preferences for one over the other. Today thrown into a casual conversation my principal mentioned that one uses same same grouping for new information and mixed ability grouping when working to solve a problem. HA! I feel like I just got the teacher edition of an upper level science textbook. So, that's the answer! I'm so excited! I have HUGE classes and have been playing with grouping for a while and this will help. Any other ideas on groups? Please share! Thanks!
