Many arithmetic problems can be solved in two ways: by a calculation involving several steps, and by direct retrieval of the answer. With practice on particular problems, memory retrieval tends to supplant calculation--an important aspect of skill learning. We asked how the distribution of practice on particular problems affects this kind of…

Students often voice computations during group discussions of mathematics problems. Yet, this type of private speech has received little attention from mathematics educators or researchers. In this article, we use excerpts from middle school students' group mathematical discussions to illustrate and describe "computational private…

Although current categories of learning disabilities include as specific disabilities calculation and mathematical problem solving [see IDEA reauthorization, 2004, Sec. 300.8(c)(10)], the majority of research focuses on calculation disabilities. Previous studies have shown, however, that deficits in word problem solving difficulties are persistent…

Describes two lessons in which a fifth grade teacher emphasized the mechanics of mathematics, such as carrying out various computational procedures, to her students. The first lesson introduced students to the concept of averages. In the second lesson, the teacher conducted class surveys to provide data for computing averages. (BB)

This framework gives direction for the development of mathematics programs in California schools. The introductory chapter discusses expectations and responsibilities: problem solving, calculator technology, computational skills, estimation and mental arithmetic, and computers in mathematics education; implementation of the recommended program,…
