Methods to transcribe and represent classroom video data are central to studying teaching and learning in classrooms. However, current methods focus on encoding and representing data over time, not space. In this paper, we demonstrate the value of a new methodological approach called interaction geography to transcribe and interactively visualize…

Teaching mathematics and science embedded in social justice is not a familiar concept for many teachers, especially pre-service teachers. This qualitative, descriptive, and interpretative study examines the experiences and reflections of 26 middle grade and secondary pre-service mathematics and science teachers on teaching and learning mathematics…

The purpose of this study was to investigate how the 8th graders interpreted the equal sign in the pan balance activities they created on Scratch. Five eighth graders (4 girls and 1 boy) in Turkey participated in this study. Case study was employed as a qualitative research method. Data was gathered through the Scratch files created by the…

Capitalizing on cognitive load theory and learning by analogy, we propose two instructional methods to learn a complex linear equation (e.g. two-step equation) by building on prior knowledge of a simpler linear equation (e.g. one-step equation). We will examine the proposal theoretically in this paper. In line with the design principles of…

This work presents an evaluation of a unified Calculus 1 course in a large Brazilian federal university. By course unification we mean having all the sections following the same weekly schedule, under the same syllabus and common assessment. We analyse two sets of data: pass rates relative to the 9 semesters prior to the unification and to the…

Probabilistic thinking is a structure of thinking characterized by scenarios that allow one to explore reality. Therefore, the characteristic of probabilistic thinking is problem-oriented that will occur in a future full of uncertainty. Nevertheless, few studies examine the students' probabilistic thinking level based on the Stress Tolerance…

This study employed an alternating treatments design to compare the effects of two types of practice conditions on the subtraction fact fluency in a fifth-grade classroom. Eight, fifth-grade students participated in the study over a 5-week intervention period practicing addition and subtraction facts in a "fact families" condition (A +…

Teachers' beliefs and skills in, and attitudes towards technology are the factors shaping their technology use in education. However, teacher preparation programs don't sufficiently support pre-service teachers in this regard. One way to improve their technology beliefs and skills in, and attitudes towards technology is to have them design…

The first 3 years of life are identified as a period where children are primed for mathematical thinking, and a time where significant and critical development occurs. Additionally, mathematical ability in the years before children start school serves as a strong predictor of later achievement. However, many early childhood educators do not…

Mathematics is the queen of science, but many students struggle with this subject as slow learners. Slow learners can accomplish their full potentials with an appropriate learning approach. In this study, these slow learners were examined using Realistic Mathematics Education approach. Single subject research was employed in this study, with…

This study aims to develop a GeoGebra-supported learning kit for teaching polygons and to examine mathematics teachers' opinions about it. The research was designed using a descriptive research model. The study group comprised 11 mathematics teachers who voluntarily participated in the in-service training called 'Dynamic Math Software (Geogebra)'…

In this article, the authors investigated the effect of comic storytelling (centred upon students' experiences in their everyday life) in enhancing students' understanding, motivation and engagement in primary mathematics. These lessons connected "out-of-school" and "in-school" mathematics, involved students telling and writing…

Mathematics standards and practices highlight the vital role that language plays in mathematics education. However, there remains a common misconception that mathematics is somehow language-free or less linguistically demanding than other content areas. This qualitative study describes an intervention implemented in six elementary mathematics…

What is a teacher to do when students share an idea with underlying mathematics that is different from that of the student contribution being discussed? Could such situations be avoided to begin with? In this article, the authors share strategies that can help teachers better keep the mathematics related to the student contribution under…

Purpose: To determine the sociocultural characteristics and unravel the ethnomathematics in "Panaeaba" or oyster farming of the fourteen "Manugtaeaba" (oyster farmer) purposively chosen as informants and paired the mathematical concepts and principles found in "Panaeaba" to K12 Mathematics. Method: This focused…
