By its nature, the learning of certain complex contents has always been a focus of attention and a challenge in the study of mathematics. This fact acquires greater importance if it is about the learning of children, because the psycho-cognitive skills of this type of user, especially when they attend the first levels of Basic General Education…

Diverse stakeholders have an interest in understanding how teacher characteristics--their preparation and experience, knowledge, and mind-sets and habits--relate to students' outcomes in mathematics. Past research has extensively explored this issue but often examined each characteristic in isolation. Drawing on data from roughly 300 fourth- and…

The study explored the evaluation of digital instructional materials (DIMs) by K-8 teachers of mathematics, positing that a useful perspective for evaluating DIMs by K-8 teachers of mathematics is considering how technology integrates with research-based practices for teaching mathematics. This paper describes the study that drew on the…

The first author's initial attempts at a whole-class mathematics discussion were woefully dysfunctional. Ten second graders showing their answers to a missing addend question about the number of children left riding a school bus did not result in the mathematical epiphany that the textbook promised. She did not give up on using mathematical…

Visualisation is an important part of the cognitive process in mathematics. Pedagogical-psychological theoretical frameworks concerning cognitive processes consider perception and visualisation as basic conditions for the creation of correct mental imagery. This study examined visualisation as a key factor in the development of geometric concepts…

This study aims to describe the teachers' obstacles in applying problem-based learning model in Mathematics learning of elementary schools. This method of this study was a qualitative descriptive. The data sources were three third-grade teachers of the elementary schools. The data analysis consisted of stages of data collection, data reduction,…

Four mathematics teacher educators from a large, minority-serving university formed a teaching research group in Fall 2016. The goal for this project is to establish a repeated cycle of improving our mathematics content course for pre-service teachers and to contribute a shared knowledge base which rests on foundation of well-defined learning…

This study was designed to examine predictors of instructional beliefs related to problem solving that influence mathematics in-service teachers' practices in the Chilean context. A total of 713 in-service mathematics teachers from various elementary schools participated in the survey study during 2015 and 2016. Results showed that teachers'…

The aim of the study is to investigate the effects of using computer for developing arithmetical skills of students with mathematics learning difficulty (MLD). The study was carried out with pre-test - post-test single subject research design. The participants of the study consist of a girl and two boys who attend 3rd grade at elementary school.…

Our consortium of four universities conducted case studies with five teachers in Grades 1 through 4 to explore how elementary teachers are implementing digital curricula, particularly whether they are developing the Mathematical Practices with digital curricula. Through observations with the Mathematics Classroom Observation Protocol for Practices…

Response to intervention (RtI) is increasingly being used in elementary and secondary schools both to provide early intervention and support to struggling students and to identify students who may benefit from special education. Although research exists to guide and support the implementation of RtI in elementary schools, much less information…

The current study examines the mental computation performance owned by students at fifth grade. This study was carried out with 118 fifth graders (11-12-year-olds) studying at 3 randomly selected primary schools that served low and middle socio-economic areas in a city of Turkey. "Mental Computation Test (MCT)" has been used to reach how…

Children start to develop number sense even well before they start the school. Developing number sense serves as an intermediate tool for learning conventional mathematics taught in schools. This number sense has three key areas: number knowledge, counting and arithmetic operations. As a result, the aim of this study was to examine aged related…

In this study we explore possible long-term effects of an adaptation of the El'konin­-Davydov elementary grades curriculum, Measure Up or MU. The objectives for the study are to assess how students relate an equation of nonnumeric quantities to a length representation, and if former MU students develop and retain a perspective characteristic of…

Percentages have proven to be a challenging concept in school mathematics. At the surface, a percentage is merely a rational number, representing a ratio between a number and 100. At the conceptual core, however, a percentage is sensitive to the context, making sense with respect to a network of related quantities. In the effort of the authors to…
