A number of respected school systems are now seeking alternatives to tracking and ability grouping, alternatives that will ensure a better education for all students whatever their abilities. This handbook introduces practitioners to educators around the United States who are developing alternatives to harmful grouping practices. After a brief review of the roots of sorting practices and their impact on teaching and learning, the book describes features of classrooms and schools that have begun to use heterogeneous groupings and other innovative strategies. These features include high expectations for all, agreed-upon outcomes, coaching to help all students, innovative learning strategies for all, structures that support inclusive learning, and counseling for all students for success. The steps that schools may take to replace traditional grouping practices include developing school-based leadership and parental support, providing professional development, and support, creating districtwide commitment, planning for change, phasing in change, and developing supporting policies. In conclusion, schools that have started the untracking process have seen student achievement and self-esteem rise. Sufficient training and resources for teachers and staff is crucial for making for process work. Contains a glossary and nine references. (LMI)
