Video-based teacher online learning enables teachers to engage in reflective practice by watching others' classroom videos, providing peer feedback (PF) and reviewing others' work. However, the quality and reliability of PF often suffer due to variations in teaching proficiency among providers, which limits its usefulness for reviewers. To improve…

This study aims at elaborating a well-established theoretical framework that distinguishes three modes of thinking in linear algebra: the analytic-arithmetic, the synthetic-geometric, and the analytic-structural mode. It describes and analyzes the bundle of signs produced by an engineering student during an interview, where she was asked to recall…

The COVID-19 pandemic resulted in significant disruption in schooling worldwide. Global test score data is used to estimate learning losses by modeling the effect of school closures on achievement by predicting the deviation of the most recent results from a linear trend using data from all rounds of PISA. Mathematics scores declined an average of…

Excellence gaps are differences in advanced education outcomes among student groups. This study replicates and extends an earlier study on the prevalence and magnitude of excellence gaps based on student sex and immigrant status using Grade 8 TIMSS data. Data were included for the 12 countries that have participated in each TIMSS administration…

The same and different routine offers an opportunity to build a strong foundation for future grades while also deepening the experiences of prekindergarten and transitional kindergarten students. Students have opportunities to make sense, share ideas, and engage in the ideas of others. We conjecture this type of experience supports students and…

This case study investigated the development of prospective mathematics teachers' technological pedagogical content knowledge (TPACK) in graphical data displays with (VM) within the context of a microteaching lesson study (MLS). This research investigated how five participants integrated technology and implemented a lesson plan aimed to teach…

The current study aimed to (i) creates a bibliometric map of studies conducted on giftedness and mathematics and covered in the Scopus database and (ii) provide a holistic examination of these studies. Analyses included 1088 studies published between 1917 and 2022. We used the VOS viewer for social network visualisations. Using the bibliometric…

This study investigates the characteristics of Japanese primary school mathematics lessons that adopt a problem-solving approach. We argue that these characteristics are reflected in three key aspects: collective teaching and learning, the lesson as a "drama" (i.e., its structured flow), and the focus on mathematical knowledge. In this…

This study aims to explore longitudinal associations among homework expectancy, mastery-approach, homework effort, and mathematics achievement involving middle school students over one school year. Results indicated that there was support for a positive reciprocal influence of mastery-approach and effort; greater initial mastery-approach resulted…

We investigate proving activities from a monistic embodied perspective, namely the functional dynamic systems (FDS) approach. Using proofs without words, we focus on proving activities that can be conceptualized as identifying and filling gaps. Using a microethnographic methodology enhanced by eye-tracking, we investigate sensory-motor processes…

Research shows that 44% of new teachers quit teaching within the first 5 years. This study aims to explore the link between teacher leadership and the retention of science and math teachers and contributes to the increasing body of research suggesting that teacher leadership could be a promising way to tackle the problem of retaining teachers in…

Mathematics vocabulary plays a crucial role in students' mathematics learning. However, students, particularly those with learning disabilities (LDs), encounter challenges in understanding and grasping mathematical terms. This challenge becomes more evident as students progress into the elementary and secondary grades, where mathematics vocabulary…

The development and use of elementary mathematics specialists (EMSs) is an indispensable approach for improving mathematics instruction in schools. This holistic singular-case study explored the teacher leadership of 26 EMSs across a three-year period as they developed in their informal teacher leader role during a five-year mathematics…

This study explores the impact of three alternative grading systems--specifications grading, standards-based grading (SBG), and ungrading--on student motivation, engagement, stress, enjoyment, and perceptions of fairness. Quantitative and qualitative analyses were conducted with students from mathematics, computer science, and statistics courses.…

In the wake of the present inclusion of programming in mathematics education, which is a feature of curricular revisions in many countries, we have analysed newly inserted programming activities in mathematics textbooks. The aim was to investigate how such activities relate to and potentially affect students' opportunities to learn mathematics.…
