The purpose of this quasi-experimental, mixed method design study was to investigate the impact of Differentiated Instruction (DI) on student performance and achievement while implementing rigor in the Algebra II classroom. The call to increase rigor in high school classrooms increases daily, and educators are rethinking teaching and learning; the…

How often are teachers surprised to find out at the end of a learning episode that students have not actually learned? The first Mathematics Teaching Practice from NCTM's "Principles to Actions" asserts that "effective teaching of mathematics establishes clear goals for the mathematics that students are learning, situates goals…

The Office of English Language Acquisition (OELA) has synthesized key data on English learners (ELs) into two-page sheets on a variety of subjects. The topics for this report on English learners and high school mathematics include: (1) Distribution of Students Enrolled in High School Mathematics Classes; (2) Percentage of Students Who Failed to…

This paper describes a project that sought to simultaneously facilitate the mathematical learning of both preservice teachers (PSTs) and schoolchildren. The project involved the organization of community Math Stations related to research-based number sense activities and was integrated within two university-level courses. This article describes…

In this study, secondary school mathematics teachers' the opinions related to skills-based questions that are compatible with the LGS (High School Transition Exam) question style were examined. Qualitative research methods were adopted in the study. Mathematics teachers working in secondary schools in various parts of Turkey participated in the…

Namibian preservice high school mathematics teachers' (N=4) and teacher educators' (N=3) beliefs about mathematics learning difficulties (MLD) were investigated to document the beliefs developed at the end of the teacher education program, the views and practices that might be emphasized in the program, and possible changes in these beliefs during…

As algebra teachers, the authors explore the following question in this article: "How can algebra 1, algebra 2, and precalculus teachers support students to develop algebraic reasoning and understanding of structure that can serve them in day-to-day algebraic computation?" The article shows how the algebraic identity "(a +…

This study aims to reveal the similarities and differences in the secondary mathematics curricula (SMC) of Turkey, Estonia, Canada, and Singapore during the 2018-2019 academic years by comparing them in terms of the curriculum components. In this context, the horizontal approach technique, one of the comparative education approaches, was used in…

The 5E instructional model is known for increasing student engagement and participation in the learning process. While viewing the video recorded lessons of middle school mathematics teachers, the researchers noticed teachers had a difficult time implementing the 5E model with fidelity. This case study explored the extent to which mathematics…

Filling the STEM pipeline from secondary schools to postsecondary institutions is essential for the nations' competitiveness in the 21st century. It is therefore crucial to motivate more high school students to consider entering one of the STEM fields and to prepare themselves by taking advanced coursework in STEM that will prime them for choosing…

This article details a high school classroom activity in which algebra tiles are used to help students gain a conceptual understanding of completing the square. The activity utilises the eight elements of effective mathematics education suggested in the National Council of Teacher of Mathematics' (NCTM's) "Principles to action: Ensuring…

A widely used instrument was implemented to ascertain the mathematical modelling competency displayed by a cohort of South African learners in grade 10 and grade 12 of the school mathematics programme in South Africa. The cohort comprised 471 grade 10 and 200 grade 12 learners from schools serving learners from low socio-economic status…

The emerging of formal mathematical proof is an essential component in advanced undergraduate mathematics courses. Several colleges have transformed mathematics courses by facilitating undergraduate students to understand formal mathematical language and axiomatic structure. Nevertheless, college students face difficulties when they transition to…

Girls' underrepresentation in high-level post-compulsory mathematics is a longstanding issue of concern in many Western nations, with innumerable efforts to increase their participation producing little impact. In this paper, we shed new light on girls' underrepresentation through a post-structural feminist investigation of mathematics teachers'…

Approximations of practice provide opportunities for teacher candidates (TCs) to engage in the work of teaching in situations of reduced complexity. A problem of practice for teacher educators relates to how to represent student voice in approximations to engage TCs with interactive practices in meaningful ways. In this article, we share an…
