This special issue focuses on mathematics for students with disabilities, particularly on the topic of division. The articles discuss a number of curricula and instructional practices that have direct and meaningful implications for the classroom. They also serve as a foundation for the development of research into effective intervention practices. As a whole this issue provides an opportunity to extract selected features of instruction from the articles found herein and to contrast the effectiveness of two distinct instructional approaches--constructivism and direct/explicit instruction.

This book includes two main sections: a discussion of problem solving and a section on computation with whole numbers. A primary theme of the text is that problem solving sets the stage for meaning and conceptual development with respect to numbers. The section on problem solving includes numerous problem-solving activities that have a dual purpose: the enhancement of language comprehension and cognitive development, and the enrichment of experiences in arithmetic problem solving. The section on computation stresses the use of both traditional and alternative arithmetic algorithms. The latter are introduced so as to provide the teacher with a means to enhance performance in the area of whole number arithmetic in such a way that the difficulties of the student are circumvented. Providing a range of arithmetic activities useful in both the general education and special education settings, the book addresses needs of students in both general education and special education.
