Ayalon, Michal; Even, Ruhama – International Journal of Science and Mathematics Education, 2016
This study examines how students' opportunities to engage in argumentative activity are shaped by the teacher, the class, and the mathematical topic. It compares the argumentative activity between two classes taught by the same teacher using the same textbook and across two beginning algebra topics--investigating algebraic expressions and…

Alajmi, Amal Hussain – International Journal of Science and Mathematics Education, 2016
This study reports on the algebraic generalization strategies used by elementary and middle/high school pre-service mathematics teachers in Kuwait. They were presented with 9 tasks that involved linear, exponential, and quadratic situations. The results showed that these pre-service teachers had difficulty in generalizing algebraic rules in all 3…

Dolev, Sarit; Even, Ruhama – International Journal of Science and Mathematics Education, 2015
This study analyzes six seventh grade Israeli mathematics textbooks, examining (1) the extent to which students are required to justify and explain their mathematical work, and (2) whether students are asked to justify a mathematical claim that is stated by the textbook or a mathematical claim that they themselves generated when solving a problem.…

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…

Yu, Jya-Yi Wu; Chin, Erh-Tsung; Lin, Chia-Jung – International Journal of Science and Mathematics Education, 2004
This research was designed to study Taiwanese junior high school students' understanding about the validity of conditional statements. Distinguishing between validity and truth is a crucial topic in mathematical reasoning and argumentation but has been always neglected in the mathematics curriculum at junior high school level of schooling. The…
