Relationship Between Computational Performance and Number Sense Among Sixth- and Eighth-Grade Students in Taiwan

Robert E. Reys, Der-Ching Yang 

March 1998, Volume 29, Issue 2, Page 225

Abstract:
This research provides information on the number sense of Taiwanese students in Grades 6 and 8. Data were collected with separate tests on written computation and number sense. Seventeen students were interviewed to learn more about their knowledge of number sense. Taiwanese students' overall performance on number sense was lower than their performance on written computation. Student performance on questions requiring written computation was significantly better than on similar questions relying on number sense. There was little evidence that identifiable components of number sense, such as use of benchmarks, were naturally used by Taiwanese students in their decision making. This research supports the need to look beyond correct answers when computational test results are reported.
