Students' ability to operate with increasingly more complex units has been shown to be a key factor in their conceptual development. These abilities have been characterized as "stages of units coordination." This article focuses on the domain of composing and decomposing composite units. Using data from a teaching experiment with a…

The current quantitative study, a naturalistic field experiment, was conducted in a public primary school in Soweto, Johannesburg, with the objective to examine how children's achievement on four assessments at the beginning of Grade R, namely their numeracy, their mathematics-specific vocabulary, their executive functions, and their logical…

Students' understanding of the meaning of the equal sign develops slowly over the primary grades. In addition to updating their representations of equations to recognize that the equal sign represents an equivalence relation rather than signaling an operation, students need to move beyond full computation to efficiently solve equivalence problems.…

Place value concepts were measured longitudinally from kindergarten (2017) to first grade (2018) in a diverse sample (n = 279; M[subscript age] = 5.76 years, SD = 0.55; 135 females; 41% Black, 38% White, 8% Asian, 12% Latino). Children completed three syntactic tasks that required an explicit understanding of base-10 symbols and three approximate…

This study explored the mathematical beliefs of two second-grade teachers. This exploration included 1) the nature of mathematics beliefs and orientation towards teaching and learning held by the teachers, 2) how their beliefs were developed and, when applicable, changed, and 3) how their beliefs influenced their mathematics instruction. It used…

Disasters continue to have adverse effects around the globe leaving many lives susceptible to hazards and fatalities most especially children. The Philippines, known to be one of the most disaster-prone countries in the world, experiences earthquakes, typhoons, and flooding yearly. For the reason of the country's vulnerability to disasters, it is…

Parent involvement has been shown to have a positive effect on second language acquisition, student motivation and academic achievement. This is particularly true for the almost five million English learners (ELs) in our PK-12 schools today and has important implications for the preparation of pre-service teachers. This study investigated how a…

In the field of collaborative action research (CAR), the quality of the collaborative partnerships between university researchers and practitioners has received much attention. Most accounts focus on three areas: the question how to organise and optimise the encounter of these 'worlds' of scientific and practical reasoning; the professional…

The topic of keeping livestock is very well suited to addressing the ecological, social, and economic aspects of the sustainable production of our food in school lessons. However, the production of animal-based foods is mainly outside the personal experience of children and young people. To derive relevant implications for teaching, this paper…

Representation in science is anything that stands for something else--drawings, pictures, graphs, or other representational forms (Danish et al. 2020). Representations serve as public displays of phenomena that make aspects of those phenomena explicit (Gilbert 2008). They can serve to make the invisible visible, communicate ideas, display…

In the quest for quality in early childhood education, it is important to explore the subtleties that define socio-culturally relevant pedagogy. A qualitative, multi-case study approach was used to explore perspectives of teachers about socio-cultural influences on their teaching in kindergarten classrooms in Ghana. Four teachers from two…

This research focuses on young children's understandings about economic, social, and environmental sustainability. Participants were 43 children, aged from 3 to 7 years of age, recruited from two kindergartens in Croatia. Children's ideas were discussed through semi-structured interviews that focused on saving, spending, recycling, justice,…

A pretest-training-posttest design assessed whether training to improve spatial skills also improved mathematics performance in elementary-aged children. First grade students (mean age = 7 years, n = 134) and sixth grade students (mean age = 12 years, n = 124) completed training in 1 of 2 spatial skills--spatial visualization or form…

Time is an essential construct for understanding our everyday lives and the wider world; however, it is commonly seen as a difficult topic by teachers and children throughout primary school. There is limited research into children's learning about time, and in particular, concerning young children's understandings of clocks. This study examines…
