Mr. Oster has an inclusion class for U.S. History where he must differentiate the assessments. Hid SPED students take an exam that has reduced answer choices. Many of the students could actually take the on-level exam and if they studied could perform at mastery level. However, since the students know they are taking an exam that is in fact easier, they do not apply themselves to study on participate in class. The lack of academic challenge is actually hindering their overall growth as a student. Mt. Oster would like to change this, but he is required to differentiate their assessments according to their IEPs. How should Mr. Oster approach this problem with assessment?
