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…

A Study of Multi-Representation of Geometry Problem Solving with Virtual Manipulatives and Whiteboard System
Peer reviewed Peer reviewed
Direct linkDirect link
Hwang, Wu-Yuin; Su, Jia-Han; Huang, Yueh-Min; Dong, Jian-Jie – Educational Technology & Society, 2009
In this paper, the development of an innovative Virtual Manipulatives and Whiteboard (VMW) system is described. The VMW system allowed users to manipulate virtual objects in 3D space and find clues to solve geometry problems. To assist with multi-representation transformation, translucent multimedia whiteboards were used to provide a virtual 3D…

The Use of a Problem-Solving-Based Instructional Model in Initiating Change in Students' Achievement and Alternative Frameworks.
Peer reviewed Peer reviewed
Chang, Chun-Yen; Barufaldi, James P. – International Journal of Science Education, 1999
Reports on the effects of a problem-solving-based instructional model on earth science students' (n=172) achievement and alternative frameworks. Results revealed that the problem-solving-based instructional model significantly improved the achievement of students, especially at the application level. Students in the treatment group experienced…

Characteristics of "Adders" in Proportional Reasoning.
Peer reviewed Peer reviewed
Lin, Fou-Lai – Proceedings of the National Science Council, Republic of China, 1991
The errors and strategies made by students who consistently use the incorrect-addition strategy on "hard" ratio tasks were investigated. The characteristics of these "adders," such as awareness of noninteger multiples, the use of fractions and decimals, awareness of both within and between ratios, and distinguishing nonratio…
