Elias, Henrique Rizek; Ribeiro, Alessandro Jacques; Savioli, Angela Marta Pereira das Dores – International Journal of Science and Mathematics Education, 2020
Our goal in this article is to organise an epistemological matrix for the concept of rational number that contemplates its different meanings. Aiming at understanding the various ways to signify the rational numbers and based on the theoretical-methodological approach of conceptual profiles, we produce and analyse data from various sources,…

Eymur, Gülüzar; Geban, Ömer – International Journal of Science and Mathematics Education, 2017
The main purpose of this study was to investigate the effects of cooperative learning based on conceptual change approach instruction on ninth-grade students' understanding in chemical bonding concepts compared to traditional instruction. Seventy-two ninth-grade students from two intact chemistry classes taught by the same teacher in a public high…

Huang, Neng-Tang Norman; Chiu, Li-Jia; Hong, Jon-Chao – International Journal of Science and Mathematics Education, 2016
The strong humanistic and ethics-oriented philosophy of Confucianism tends to lead people influenced by these principles to undervalue the importance of hands-on practice and creativity in education. GreenMech, a science and technology contest, was implemented to encourage real-world, hands-on problem solving in an attempt to mitigate this effect.…

Lee, Mi Yeon; Hackenberg, Amy J. – International Journal of Science and Mathematics Education, 2014
To investigate relationships between students' quantitative reasoning with fractions and their algebraic reasoning, a clinical interview study was conducted with 18 middle and high school students. The students were interviewed twice, once to explore their quantitative reasoning with fractions and once to explore their solutions of problems…

Calik, Muammer – International Journal of Science and Mathematics Education, 2005
This study reports on research examining what students think about aspects of solution chemistry and seeks to establish what alternative conceptions they hold in this area. To achieve this aim the researchers developed a test comprising of open-ended questions that evaluated students understanding of solution chemistry. The test was administered…

Yen, Chiung-Fen; Yao, Tsung-Wei; Chiu, Yu-Chih – International Journal of Science and Mathematics Education, 2004
This study examined students' alternative conceptions of reptiles and amphibians and the extent to which these conceptions remain intact through the elementary (grades 4 and 6), junior, and senior high school years. We administered multiple-choice and free-response instruments to a total of 513 students and interviewed at least 20 students at each…
