Programs that have the potential to improve all intermediate grade students' opportunities for learning are identified and examined in this report. This 1989 review of over 200 programs focuses on 80 programs that stress high academic content or new access for educationally disadvantaged students in the middle grades. However, none can be labelled "effective" due to serious measurement and evaluation problems. Following a preface and an introduction, chapter 1 discusses important issues underlying the identification of promising programs for disadvantaged students in the middle grades and their common components. Chapter 2 offers examples of programs to improve mathematics, reading, writing and language arts, thinking skills, science, and social studies. Common themes of the programs are discussed in the third chapter, which highlight the belief that all students can learn; the importance of commitment; the limitations and benefits of pullout programs; the view of the educational system as a community; and the need for both prevention and treatment programs. Appendices include a directory of promising programs in each of the subject areas and the survey and discussion guide. (50 references) (LMI)
