In this article, the authors describe their experiences with planning, implementing, and revising a lesson for which the goal is for students to consider the mathematical and pragmatic issues that are related to a task of maximizing the area for a fixed perimeter. The authors also wanted students to engage in the Standards for Mathematical…

For more than a decade, government primary-school teachers in many parts of India have been using mathematics textbooks based on National Curriculum Framework 2005 (NCF 2005). While curriculum and textbook development is often debated, teachers' use of textbooks does not receive enough attention in policy and research. This article, drawing from a…

Digital media have become increasingly important in recent years and can offer new possibilities for mathematics education in elementary schools. From our point of view, geometry and geometric objects seem to be suitable for the use of computer-aided design software in mathematics classes. Based on the example of Tinkercad, the use of CAD software…

Professional development programs today increasingly ask teachers to capture video in their own classrooms to share with peers. Yet little work has explored the nature of the videos that teachers produce for this purpose. This study takes a first step by looking inside a set of almost 200 videos collected by 84 K-2 teachers participating in one of…

The purpose of this causal-comparative study was to gain insight into whether teaching fractions improves teachers' understanding of fractions. University master's students (n = 25) conducted tutoring on fraction magnitude in grades 3-5. The contrast condition, 17 master's students drawn from the same pool of research assistant applicants,…

This study presents a teaching experiment in which second-grade primary school students compared a city and a town according to population estimates. The activities were presented to them as Fermi problems and required an analysis of the reality to identify sub-problems that students could deal with. The students' products were analyzed from the…

It is important to determine the behaviors of primary school pre-service teachers, who have successfully completed the "Mathematics Textbook Review" course during their undergraduate education, regarding the use of textbooks in their professional life. Therefore, it is important to determine the approaches of pre-service teachers who…

Within a global context of more standardization of teacher preparation, programs in the USA are increasingly using standardized teacher performance assessments such as edTPA to evaluate prospective teachers' instructional effectiveness and readiness for their own classroom. This study was conducted in a state recently requiring successful…

The aim of this study is revealing the strategies used by 5th-grade students in comparing fractions. In line with this purpose the study is based on qualitative research. Participants of the study conducted with convenient sampling method are seventy 5th-grade students. The students have been asked six questions which necessitate comparison of…

This study investigated the effectiveness of cognitive-behavioral therapy (CBT) on math anxiety and math self-concept in elementary school students using an experimental design. For this study, we selected 30 students with high mathematics anxiety and low mathematics self-concept from a larger sample of 142 elementary school students in Arak City,…

The aim of this study is to obtain information about students' definitions, mistakes, misconceptions, and van Hiele geometry thinking levels by using the definitions of 4th grade students for geometric shapes of rectangle, square, isosceles triangle, equilateral triangle, and scalene triangle. The study was carried out with 156 primary school 4th…

This paper reports on a project that sought to enhance problem-solving practices within a cluster of primary schools. In-service teachers' description of their approach to problem-solving suggested it was treated as an isolated practice that occurred after concepts had been taught; often focusing on teaching particular problem-solving strategies…

This dissertation is guided by my driving research question: what works for whom in education and why? I examine issues of instruction, assessment, and research approaches that begin to answer this question. Study 1 examines a classroom intervention's child x instruction interactions. Study 2 examines underlying cognitive factors, including…

This study examines whether associations between enrollment in public and non-public PreK and children's (N = 508; M[subscript age] = 5.60 years in fall of kindergarten) math and language and literacy outcomes were more likely to be sustained through the spring of kindergarten for unconstrained versus constrained skills. Associations between…

With the rapid advancement of information technology, the Intelligent Teaching System (ITS) has emerged as a pivotal tool in mathematics education. This paper aims to evaluate the effectiveness of ITS by exploring its impact on personalized learning, increased student interaction and participation, intelligent assessment and feedback, teacher…
