This purpose of this quasi-experimental, ex-post facto study was to examine the effect of SpringMath as a classwide intervention for students in grades kindergarten through second grade within one elementary school. In order to research the effects of SpringMath on the whole-number computational fluency of kindergarten through second grade…

Teachers' noticing of students' mathematical thinking plays an important role in supporting student learning. Yet little is known about how online professional development (PD)--a growing setting for PD in the USA--can cultivate this noticing. Here, we explore the potential of using two online tools for engaging video to support K-2 teachers'…

This comparative study analyzed the similarities and differences in the mathematical communication used by teachers and primary school students in Japanese, Lao, and Thai mathematics classrooms. It adopted a qualitative research design, and the targets were teachers and students in Grades 1-6 at a selected school in each of the three countries.…

Interventions targeting cognitive control processes, such as Executive Functions (EF) have recently been experimented to enhance early math skills. This pilot study explored the feasibility and effectiveness of an intervention integrating EF activities into the mathematical domain among second-grade students. One hundred and four…

This study examined the amount and quality of educational dialogue in relation to student math performance in Grade 2. Domains of teacher occupational stress were considered predicting variables for dialogue and math performance. Video-recorded lessons (N = 151) of 50 teachers were analysed in terms of dialogic episodes to determine the amount…

In 2014, over 30 classroom teachers and administrators from one district joined higher education faculty and researchers from an educational non-profit organization to begin a three-year collaborative project. They wanted to find ways to leverage the use of one-to-one mobile technology (tablets) in kindergarten-2nd-grade mathematics classrooms to…

Background: The co-establishment of social and sociomathematical norms in the microculture of South African classrooms and its possible effects on early number learning has largely been unexplored. Social norms are considered to be general classroom norms that are relevant in any teaching and learning space, whilst sociomathematical norms are…

Research showed that the capacity of making simple estimations begins to develop already at the age of five, but little is known about the early development of this estimation capacity and the strategies that underly it. The current study longitudinally followed the estimation capacity and strategies of 332 children from first to second grade of…

Abstract Lego construction ability is associated with a variety of spatial skills and mathematical outcomes. However, it is unknown whether these relations are causal. We aimed to establish the causal impact of Lego construction training on: Lego construction ability; a broad range of spatial skills; and on mathematical outcomes in 7-9-year-olds.…

Teachers' noticing of students' mathematical thinking plays an important role in supporting student learning. Yet little is known about how online professional development (PD)--a growing setting for PD in the USA--can cultivate this noticing. Here, we explore the potential of using two online tools for engaging video to support K-2 teachers'…

Feedback does not always engage students. To better understand why this happens, the present study analysed Grade 2 (7- to 8-year-old) students' experiences of formative feedback in mathematics to identify aspects with potential importance for student engagement. The researcher processed the students' experiences with the help of stimulated recall…

Children's early accuracy on place value (PV) tasks longitudinally predicts their later multidigit calculation skills. However, another window into children's emerging base-ten concepts is the pattern of errors -- "smart errors" -- they exhibit on these measures. Past research has speculated that these smart errors -- similar to invented…

Computational thinking (CT) has become central to introducing digital artefacts for educational use. However, little is known about implementing CT in the mathematical school curriculum, and many educational staff members have not been introduced to CT in their initial training. Introducing CT in an educational setting calls for interventions that…

Properties of arithmetic operations are important in mathematics and play a significant role in elementary school students' learning of mathematics. At the same time, it is quite challenging to help students learn arithmetic operational properties beyond memorization, so that they know when and how to use a specific arithmetic property. This paper…

In the early years of school, pupils have a very positive approach towards any new topic. Very often, the first contact with mathematics in the Italian school risks giving a limited and somehow negative impression, generating long-lasting effects. In this paper, we report on a series of experiences carried out in a second-year class of a primary…
