Decimals and the related areas of ratio and proportion are recognised as one of the most challenging and complex areas of mathematics for young children to learn. In this study, four dynamic digital representations were used by Year 4 (9-10 years old) students in a set of video-recorded, individual task-based interviews to explore key concepts of…

Available data indicate educators struggle to implement interventions consistently across time, which negatively impacts student outcomes. Implementation strategies have been developed to improve treatment fidelity, but many require time and staffing demands that can be unfeasible in practice. The primary purpose of this study was to extend the…

Parents can play a key role in their children's homework activities; this has been particularly true during the home-schooling caused by the pandemic. However, how parents affect students' mathematical activity is scarcely researched, in particular in the case of primary school students. Within the framework of activity theory, in this…

Math Innovation Zones (MIZ) is a strategic grant initiative first introduced by the Texas Education Agency (TEA) in 2018. A novel state-initiative aimed at increasing PreK - 8th grade math proficiency, the highly competitive grant program provides funding to both Texas school districts and open enrollment charter schools using allocations through…

Algebra has long been a gatekeeper to more advanced mathematics and to tertiary education. International assessments, such as PISA, have also shown that this trend extends beyond borders, making the topic of when algebra should be learned quite political. Many reforms have been instituted since the early 1990s to infuse algebraic thinking into…

First-year elementary pre-service teachers usually conduct field observations but are barely offered opportunities to engage in well-structured teaching situations. In the current study, we implemented mixed-reality simulations (MRS) in a mathematics methods course to improve elementary pre-service teacher's abilities to elicit, question, and…

The paper reflects on a teaching intervention which utilized digital storytelling as an approach for teaching the subtraction algorithm in 2nd Grade. Literature indicates that this is a difficult topic for children of this age. The aim was to examine if through digital storytelling, students find it easier to understand and apply the two…

In 2018, the Texas Education Agency (TEA) introduced a competitive grant program designed to assist Local Education Agencies (LEA) in attaining Math Innovation Zone (MIZ) designation through a four-year process which ensures program fidelity. The primary objective of this initiative is to enhance math proficiency levels for PreK - 8th grade…

In this study, it was aimed to reveal the effect of using technology on the students' academic achievement in primary mathematics education. In accordance with this purpose, the current study is to determine the overall effect size by bringing together the experimental studies conducted on the effect on students' academic achievement of using…

The inquiry-oriented and cyclic process of action research can lead to the innovative use of technology and instructional strategies to improve teaching practice, particularly for beginning teachers. This action research project examined the impact of the number line and Educreations on second-grade students' verbal and written explanations of…

With the advent of mobile technologies, well-designed fraction apps can be used to help children gain fraction knowledge, a challenging topic for both teachers and students. The present pilot study adopted a quasi-experimental design to investigate whether children can learn fraction concepts equally well if half of the lesson time (20 min) is…

A randomized controlled trial group design study funded by IES NCR Grant R305A090527 was conducted in which 16,307 3rd, 4th, and 5th grade students in 52 school grade-level clusters were randomly assigned to receive ST Math (program revision Gen3), a supplemental mathematics software instructional intervention, or to a business-as-usual…

Previous research has verified the benefits obtained when learners trace out worked examples with the index finger. Our study conducted two experiments to explore the reasons for this phenomenon and its generalizability. Experiment 1 compared the learning effects among tracing, non-tracing, and cueing methods. The cueing method was included to…

Multi-touch interfaces allow for direct and simultaneous input by several co-present learners and afford hands-on learning experiences. Additional scaffolding for strategic behavior and/or verbalizations may constructively complement collaborative learning with a multi-touch device. In this study, the tablet app "Proportion" is supposed…

We have used "GeoGebra," a dynamic geometry software environment, to explore how Year 4 students understand definitions of angles. Seven students defined angle and then completed several activities adapted for the dynamic environment. Afterward, students again shared their definitions of angles. We found that even a short investigation…
