State standards include fluent use of standard computational algorithms. However, learning and using them require conceptual understanding of numbers and operations. Previous research using the concrete--representational--abstract (CRA) sequence has been effective in teaching computational algorithms to students at risk of and students with…

The current study provides new evidence on the sustained benefits of preschool attendance on a broader range of skills--both academic and executive functioning (EF)--than many prior studies have examined. Using propensity score methods, we predicted children's (N = 920, M age at 1st = 6.5 years) literacy, language, math, and EF skills in…

This study aimed to investigate the effects of augmented reality (AR) applications in geometry teaching on academic achievement, self-regulated learning skills (SRLS), and motivation of secondary school students. The research was carried out on students in the eighth grade at a state secondary school in Turkey. The research was carried out…

This paper examined how teachers' noticing skill affects the social and socio-mathematical norms they construct in the classroom. The study was carried out with four mathematics teachers working at a secondary school in the eastern regions of Turkey. A case study among qualitative research methods was used. The data of the research were collected…

In this study, a STEM activity was designed and implemented for eighth-grade students. The activity was used with thirty students and involved the construction of various hologram pyramids. During the activity, the mathematical concepts used in designing the hologram pyramids were discussed and the resulting hologram images were compared…

The purpose of this paper is to evaluate the reality of teaching and learning with the support of a calculator, examine the benefits and challenges of using a calculator in teaching mathematics in high school. The study is based on the survey data from math teachers, educational managers, and students who were selected from 24 high schools in…

This study aimed to evaluate the students' efficacy in literacy and numeracy skills in commerce subjects in secondary schools in Fiji. Focus group discussions and semi-structured interviews were used to gather relevant data. The findings show that literacy and numeracy skills are essential in commerce subjects, as students require basic literacy…

Children's knowledge of the ordinal relations among number symbols is related to their mathematical learning. Ordinal knowledge has been measured using judgment (i.e., decide whether a sequence of three digits is in order) and ordering tasks (i.e., order three digits from smallest to largest). However, the question remains whether performance on…

A child's home environment has been shown to be related to the development of early numeracy skills in some countries. However, significant relationships between home learning environment and math achievement have not consistently been found, and likely vary across different cultural and socio-political contexts. Here we explored the home…

Techno-mathematical Literacies (TmL), which are defined as a combination of mathematical, workplace and ICT knowledge, and communicative skills, are acknowledged as important learning goals in STEM education. Still, much remains unknown about ways to address them in teaching and to assess their development. To investigate this, we designed and…

Research has shown that computational thinking and kindergarten mathematics instruction can be integrated; however, evidence of how specific mathematical knowledge relates to computational thinking remains scarce. Additionally, we do not know if and how children's mathematical knowledge co-occurs with computational thinking and how these…

To stay up with society and technology, pedagogical changes are needed. Even a well-designed curriculum depends on teachers, who implement it. Knowledge drives this field's educators' actions. This dissertation examined how the Southwest New Mexico Elementary Mathematics Specialists (EMS) program affects elementary mathematics teachers' PCK.…

The purpose of this multiple case study was to explore affordances for STEM-related skills in a nature preschool in central Texas. Observations were conducted along with the collection of videos and photographs of four preschool-aged participants. Informal interviews were also implemented during data collection and observations. Semi-formal…

The development of early numeracy skills in preschoolers is an important predictor of future academic performance. A multiplicity of tasks or tests measure early numeracy skills in the English-language. Nevertheless, no tools are currently in French for evaluating and monitoring the development of young children's early numeracy skills. The…

I investigated the relationships between mathematics achievement on the Iowa Assessments and the mastery of four epistemic actions: selecting, analyzing, computing, and representing. These epistemic actions play a crucial role in characterizing mathematical reasoning and are essential for solving mathematics problems in the Iowa Assessments across…
