Ekawati, Rooselyna; Lin, Fou-Lai; Yang, Kai-Lin – International Journal of Science and Mathematics Education, 2015
In this study, we developed an instrument for assessing teachers' mathematics content knowledge (MCK) on ratio and proportion and examined the profile of Indonesian primary teacher's MCK on this topic. The MCK items were administered to 271 Indonesian in-service primary teachers with a variety of educational backgrounds and teaching…

The Reading Comprehension of Geometric Proofs: The Contribution of Knowledge and Reasoning
Peer reviewed Peer reviewed
Direct linkDirect link
Lin, Fou-Lai; Yang, Kai-Lin – International Journal of Science and Mathematics Education, 2007
A model of reading comprehension of geometric proofs (RCGP) has recently been proposed by the authors. This article further investigates students' development of such comprehension based on this model, looking at the relationship between students' reading comprehension and their prior knowledge and logical reasoning. The results show that (1)…

The Features and Relationships of Reasoning, Proving and Understanding Proof in Number Patterns
Peer reviewed Peer reviewed
Direct linkDirect link
Lin, Fou-Lai; Yang, Kai-Lin; Chen, Chuang-Yih – International Journal of Science and Mathematics Education, 2004
Three issues about students' reasoning, proving and understanding proof in number patterns are investigated in this paper. The first is to elaborate the features of junior high students' reasoning on linear and quadratic number patterns. The second is to study the relationships between 9th graders' justification of mathematical statements about…
