especially in a HS math classroom. I have heard/read about the term "differentiated instruction". (Note: I did not go to college for education so I may not have the educational training & background that some or most of you do). Am I to understand that the kids in the same classroom are working on different learning objectives or lessons? If so, how do you as a teacher manage that? Are the students themselves ok with that? Or do you hear "why do i have to do the hard problems when Sally doesn't?"from them and/or their parents. Or is it (DI) simply spending more time with the kids who are a little behind while the more proficient students work ahead at their own pace while all are working on the same learning objective? A case study: in a recent lesson on special right triangles I put in some review problems on simplifying radicals because I knew the weaker students would require it. Even though we have seen them (radicals) throughout the year. That was not really the learning objective for the day. In a true DI classroom, would the weaker students be doing that (simplifying radicals) as an objective while the better students had solving right triangles as their lesson objective? If that is the case, do you as a teacher have two or more preps for the same class? And how do you manage that? Thanks for any insight. I am obviously a bit uncertain as to what it (DI) actually looks like for both student and teacher.
