Computational Estimation Performance and Strategies Used by Fifth- and Eighth-Grade Japanese Students.
Peer reviewed Peer reviewed
Reys, Robert E.; And Others – Journal for Research in Mathematics Education, 1991
Computational strategies and estimating abilities of 466 Japanese students were tested and interviews with a subsample of that group were used to compare with a theoretical model based on a sample from the United States. Results of the comparison of computational and estimating abilities are presented. (CW)

Research into Practice: Place Value and Addition and Subtraction.
Peer reviewed Peer reviewed
Wearne, Diana; Hiebert, James – Arithmetic Teacher, 1994
Compares the development of two students' understanding of addition and subtraction. One student's understanding is based on memorized rules and the other's on understanding the concept of place value. Discusses the effects of different goals for instruction and the importance of understanding place value. (MDH)

From "Algorithmic Mode" to "Conceptual Gestalt" in Understanding the Behavior of Gases: An Epistemological Perspective.
Peer reviewed Peer reviewed
Niaz, Mansoor; Robinson, William R. – Research in Science and Technological Education, 1992
Compares performances of students on gas-law problems that require two distinct approaches, either the algorithmic technique or the conceptual gestalt. Indicates that student effectiveness is considerably different utilizing each approach and that training or experience with the algorithm process should not be expected to facilitate the…
