In the world where we always meet geometric constructions, it is a necessity to make sense of the objects belonging to these constructions. In this respect, this study aimed to examine the teaching of volume with the blending of the realistic mathematics education (RME) and GeoGebra. The study group consisted of 12 students attending lessons…

This study aimed to contribute to the literature by focusing on the effects of the negotiations of sociomathematical norms perceived by students on mathematical process skills. Problem-based mathematical activities were implemented in the seventh grade from a public secondary school in Turkey over a ten-week period in the second semester. The data…

The Modelling Dance task is a mathematical modelling task that explores the relationship between mathematics and dance. The authors share the task sequence, adaptations made to support virtual implementation, and evidence of student learning related to learning goals.

Increasingly individuals with Intellectual Disability (ID) are showing the capability of learning abstract mathematical skills like algebra. The purpose of the study was to show a method for teaching high school-aged individuals with ID the algebra skill of creating an equation from a line using a time-delay strategy and equation template. We…

In the COVID-19 era of adapting to pandemic lockdown protocol, teaching practices have become more negotiable and less tethered to the familiar and institutionally normative practices found in educational settings around the world. With a shift to online teaching, many practices are being adapted from face-to-face settings and being imported into…

This article aims to measure and compare the effectiveness of voucher schools and public schools on mathematics and reading test score trajectories from Grade 4 to Grade 10 in Chile. We analysed a national database that includes measures taken in 2007, 2011, and 2013 from a same sample of over 140,000 students. Multilevel-growth models were used…

The purposes of the study were 1) to investigate the effectiveness of the applied cooperative learning and Polya's problem-solving process on grade 9 students' mathematical problem-solving ability, 2) to compare grade 9 students' learning achievement before and after learning through the applied cooperative learning and Polya's problem-solving…

In this paper we present a theoretical discussion on how problems issued from discrete mathematics can develop the attitudes, skills, and knowledge required for scientific mathematical activity in the classroom. We do so via the research situation for the classroom model by performing mathematical and didactical analyses of a problem issued from…

Many pre-service teachers suffer from mathematics anxiety, which hinders their mathematics learning. This can cause a deficit in their mathematics content knowledge, which must be addressed to become effective mathematics teachers. The present study explored whether positive expressive writing was better at mitigating pre-service teachers'…

To promote understanding of and interest in working with data among diverse student populations, we developed and studied a high school mathematics curriculum module that examines income inequality in the United States. Designed as a multi-week set of applied data investigations, the module supports student analyses of income inequality using U.S.…

This article discusses the meanings of mathematics teaching forged in the reflections promoted in a lesson study. Guided by the question "What meanings of teaching in mathematics are constructed from reflections promoted in a lesson study?" and based on Isabel Alarcão's (2018) concept of teaching, we examined four editions of a lesson…

The main purpose of this study was to investigate on how Mathematics teachers' demographic variables could influence their instructional effectiveness in Senior secondary schools in Cross River State, Nigeria. To achieve the purpose of this study, two research hypotheses were generated to direct the study. Literature review was done according to…

The purpose of the study is to enumerate the representations in high school geometry, to narrow the focus to the most common ones, and to describe how the common representations are coordinated. To achieve this purpose, I analyzed several sections of a popular geometry textbook using thematic analysis, semiotics, and a pragmatic approach to…

As currently developed and written, mathematical word problems lack cultural relevance for an increasingly culturally diverse population in elementary schools in the United States. The design and context of mathematical word problems promote the norms, values, and beliefs of the dominant culture while potentially negatively influencing students…

Many undergraduate degrees have a mathematics requirement that students must complete to graduate. Mathematics courses are often access points and can become barriers to student progress. To address this, post-secondary institutions may implement early alert programs to offer a systematic approach to identifying and intervening with students…
