Albarracín, Lluís; Ferrando, Irene; Gorgorió, Núria – International Journal of Science and Mathematics Education, 2021
This paper presents a qualitative study developed with a group of 16-year-old students who were asked to estimate large numbers of elements on a bounded surface. Taking the realistic mathematics education framework as a reference, we presented the students with an activity sequence comprised of four different tasks--each one with a different…

Basyal, Deepak; Jones, Dustin L.; Thapa, Mohan – International Journal of Science and Mathematics Education, 2023
We investigated the cognitive demand of the exercise problems that middle school students from Nepal are expected to complete. The middle school (grades 6, 7, and 8) mathematics textbooks examined in this study were published and distributed by the government of Nepal. Our data set consisted of textbooks that are currently in use in public schools…

Türker Biber, Belma; Yetkin Özdemir, Iffet Elif; Lesh, Richard – International Journal of Science and Mathematics Education, 2023
In this study, we investigated mathematics teacher's noticing of students' thinking in the context of mathematical modeling activities (MEAs) related to statistics. One middle-school mathematics teacher participated in the study, which adopted a case study design. Data were collected through interviews with the teacher based on video recordings of…

Daher, Wajeeh M.; Shahbari, Juhaina Awawdeh – International Journal of Science and Mathematics Education, 2015
Engaging mathematics students with modelling activities helps them learn mathematics meaningfully. This engagement, in the case of model eliciting activities, helps the students elicit mathematical models by interpreting real-world situation in mathematical ways. This is especially true when the students utilize technology to build the models.…

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.…
