The Models and Modeling Working Group at PME-NA has provided a forum for discussing and collaborating on projects fundamental to research on mathematical modeling since the first PME-NA conference in 1978. We propose to convene this Working Group at PME-NA 41 with a dual purpose: (1) to build on a theme begun in Greenville, holding a focused…

To guide school librarians in their work of inspiring future generations of explorers, AASL tasked a 2020 ALA Emerging Leaders team with developing a guide of activities, resources, and professional development based on the Explore Shared Foundation in the "National School Library Standards." As learners prepare for college, career, and…

Collaborative learning requires a lot of talk. Although not all student talk may be related to the task at hand, some off-task talk is actually productive, as it enables students to negotiate how they will work together, gain attention of fellow group members, and draw others into joining the work. Emma C. Gargroetzi, Rosa D. Chavez, Jen Munson,…

The aim of this paper is to analyse the reasoning and symbolisations used by sixth grade Moroccan students in solving a task based on figurative patterns. Our analysis aims at identifying the systems of actions elaborated by the students to give the general expression of the sequence, according to their perceptions of the sequence of its patterns.…

Learning the content of entrepreneurship arithmetic is an extension of social arithmetic that focuses on mathematical calculations in business or creative economy. Most teachers do not link students' daily activities to classroom teaching and learning on traditional markets around the environment. This significantly affects the interest in…

Students from marginalized populations may be less likely to engage in science education and form science identities. Thus, science education should include culturally responsive pedagogy to engage students from diverse cultural and ethnic backgrounds and promote science identity in every student (Mhakure and Otulaja 2017). The author is a high…

This article presents some paper-folding activities for students to explore a different way to prove some of the angle properties in a circle.

We discuss teaching and learning situations that surfaced when computer programming and mathematics were brought together in a course where students write computer code to explore mathematics problems. Combining programming and mathematics creates a rich ecosystem which, on top of traditional mathematics activities (writing solutions, proofs,…

This article is based on classroom application of a problem story constructed by Amos Tversky in the 1970s. His intention was to evaluate human beings' intuitions about statistical inference. The problem was revisited by his colleague, the Nobel Prize winner Daniel Kahneman. The aim of this article is to show how popular science textbooks can…

Ferris wheel is one amusement playground that resembles a giant spinning wheel. Many students are familiar with the Ferris wheel in the mini version of it at night market festivals. This is the potential for learning mathematics. Furthermore, there is a mathematical learning approach called Indonesian Realistic Mathematics Education (IRME) where…

In this study, the relationship among the group creativity, empathy, and scientific inquiry ability of elementary school students were investigated. For this purpose, average scores and standard deviations of the group creativity problem solving, empathy, and scientific inquiry ability inventory were calculated and their correlation was analysed…

Fisheries scientists make sure that fish populations ("fisheries") are managed properly, neither over- or under-utilized, to maintain long-term economic and ecological stability. Scientists collect data and conduct surveys to determine fish populations, and then make recommendations about how many fish may be caught by commercial and…

This research study was conducted to examine the effectiveness of activity-based science teaching practices on the acquisition of problem-solving skills for 5-6 year old preschool children. A total of 32 children were included in this research study. The Personal Information Form and 4-7 Age Problem Solving Ability Scale were used as the data…

This study involves the development and implementation of a STEM activity containing 3 D printer technology, which is commonly used in STEM education. Out of school STEM courses were organized with seven middle school students studying in the 7th grade and the activities in the course were carried out with a 3D printer. One of the activities in…

This study aims to study the effectiveness of jumping task application based on creative problem solving in improving students' problem-solving abilities. The study was applied triangulation method, namely qualitative and quantitative methods. The research subject is eighth grade of Junior High School students. The research sample consists of…
