Lin, Yung-Chi; Yang, Der-Ching; Li, Mao-Neng – EURASIA Journal of Mathematics, Science & Technology Education, 2016
A web-based two-tier test (WTTT-NS) which combined the advantages of traditional written tests and interviews in assessing number sense was developed and applied to assess students' answers and reasons for the questions. In addition, students' major misconceptions can be detected. A total of 1,248 sixth graders in Taiwan were selected to…

Peer reviewed Peer reviewed
Direct linkDirect link
Yang, Der-Ching – Educational Studies, 2005
In an interview setting, 21 6th-graders from four public schools in south Taiwan were asked a series of questions, related to whole and decimal numbers, designed to assess their number sense. Eight students were randomly selected from both low and middle performance levels, and five were selected from a high-performance level, according to their…

Relationship between Computational Performance and Number Sense among Sixth- and Eighth-Grade Students in Taiwan.
Peer reviewed Peer reviewed
Reys, Robert E.; Yang, Der-Ching – Journal for Research in Mathematics Education, 1998
Provides information on the number sense of Taiwanese students in grades six and eight. Indicates that student performance on questions requiring written computation was significantly better than on similar questions relying on number sense. Supports the need to look beyond correct answers when computational test results are reported. Contains 29…

A Study of Teaching and Learning Number Sense for Sixth Grade Students in Taiwan
Peer reviewed Peer reviewed
Direct linkDirect link
Yang, Der-Ching; Hsu, Chun-Jen; Huang, Ming-Chiang – International Journal of Science and Mathematics Education, 2004
Two public schools (A and B) from two cities in southern Taiwan were selected to participate in this study. In each school, two sixth grade classes (an experimental and a control class) were studied. Number sense activities were conducted in the experimental classes through process-oriented teaching model to help children develop number sense,…
