Reys, Robert E. – Elementary School Journal, 1984
Begins with a definition of mental computation and then provides an overview of its evolution during the twentieth century. Significant benefits from teaching mental computation are highlighted, along with a framework and guidelines for instructing elementary school students. A parallel discussion is also provided for computational estimation. (RH)

Reys, Barbara J.; Reys, Robert E. – 1993
While the emphasis and content of school mathematics differ little between Japan and America, by the time students reach junior high school, performance as measured by international studies differs greatly. This report provides a profile of the attitudes toward, strategies used, and performance on mental computation of Japanese students in grades…

Reys, Robert E.; And Others – Journal for Research in Mathematics Education, 1995
Assessed attitude, computational preferences, and mental computational performance of 176, 187, 186, and 206 Japanese students in grades 2, 4, 6, and 8, respectively. Found wide ranges of performance on mental computation, that visual modes of presentation increased performance levels, and a narrow range of strategies. Contains assessments. (37…

Reys, Robert E.; Nohda, Nobuhiko – 1994
This book, written by participants of a joint Japan-United States seminar, drawing upon years of classroom and research experience, examines how computation applies in basic and far-reaching ways, starting in early childhood and continuing throughout individuals' lives. The book presents both the Japanese and American views of computational…

Reys, Robert E.; And Others – 1984
This report summarizes a project to develop computational estimation materials for students in grades 6, 7, and 8. In chapter 1, the need for estimation skills is discussed and the goals of the project are stated: to develop a carefully sequenced set of lessons, activities, and maintenance work on estimation with whole numbers, fractions,…

Reys, Robert E.; And Others – 1980
This study focuses on the mental processes used during estimation. This research: (1) developed an operational definition of estimation; (2) created an instrument to identify exceptionally good estimators; (3) collected performance level data on 1187 subjects; (4) constructed interview problems and developed protocols to identify the thinking…
