This study examines in-service mathematics teachers' problems on linear relationships that they posed in a semi-structured problem posing situation with a group and their ideas about the factors affecting the quality of the posed problems. Eight groups of 24 teachers participated in the study. Teachers' problems, written group work, and class…

In professional training courses, developing incumbents' professional knowledge and problem-solving skills when facing clinical and urgent situations is a crucial point. In conventional professional training, usually the learning content is delivered in a lecture-based mode using instructional videos with some case studies. In such a training…

In participatory action research (PAR), university-based researchers often take foundational concepts such as transformation, empowerment, critical consciousness, and mutual understanding for granted as desirable or necessary outcomes or achievements. We discuss the danger of this and suggest that researchers recognize these as processes that…

Solving complex problems is critical to educational leaders' ability to achieve improvement in schools. Much of this problem-solving is carried out in conversations with staff. This paper draws on theories of collaborative problem-solving and interpersonal effectiveness to examine the behavior of leaders in such conversations -- in Norway and New…

Evidence in South Africa of poor performance on word problems points to particular challenges among learners relating to difficulties with, on the one hand, making sense of mathematical word problems and, on the other, moving beyond inefficient counting based calculation methods. While many studies in mathematics education in South Africa have…

This paper explores how authentic assessment can be implemented to enhance opportunities to develop employability skills through problem-solving tasks. Based on the eight key tenets of authentic assessment (Ashford-Rowe, Herrington and Brown, 2014), this paper presents formative and summative assessment case studies which were created in…

Drawing on a concept-map methodology, we investigated how 18 prospective elementary teachers (PSTs) conceptualize STEM thinking as habits of mind shared across STEM domains in the context of problem-solving prior to explicit classroom discussions about STEM thinking. A 28-question, 5-point Likert-scale survey was used to explore PSTs' orientations…

As digital technologies become a commonplace in mathematics classrooms, they transform the ways students and teachers interact with mathematics. Students learn to use a technological tool for solving mathematical tasks through a process known as instrumental genesis. Teachers' support for this process is known as instrumental orchestration. In…

The usefulness of virtual reality (VR) technology in physiology education is largely unexplored. Although VR has the potential to enrich learning experience by enhancing the spatial awareness of students, it is unclear whether VR contributes to active learning of physiology. In the present study, we used a mixed-method research approach to…

Assessing sensitivity to unmeasured confounding is an important step in observational studies, which typically estimate effects under the assumption that all confounders are measured. In this paper, we develop a sensitivity analysis framework for balancing weights estimators, an increasingly popular approach that solves an optimization problem to…

This article reports two primary school teachers' perceptions of the effectiveness of lessons based on a problem-solving intervention. The intervention included enabling and extending prompts, independent student struggle time initially and time to share problem-solving strategies at the end. The intervention had two versions: one included whole…

Using mathematical modelling to solve problems appears in all year levels in the Australian Curriculum: Mathematics (v. 9), and is probably the most authentic way of teaching mathematics in context. However, the term mathematical modelling, even if familiar to teachers, may not be well understood or enacted confidently by teachers in their…

A frequent concern about constructivist instruction is that it works well, mainly for students with higher domain knowledge. We present findings from a set of two quasi-experimental pretest-intervention-posttest studies investigating the relationship between prior math achievement and learning in the context of a specific type of constructivist…

Exchanges of help between children are common and often have positive consequences. But not all help is equally beneficial, for example because some help does not provide an opportunity to practice and develop skills. Here I examine whether young children might perpetuate competence-based inequality by providing incompetent peers with less…

The purpose of this study was to provide recommendations to solve the problem of low teacher retention for the Houston Independent School District (HISD) in Houston, Texas. The problem was that 25% of teachers resigned from HISD (Carpenter, 2019). This makes the teacher retention rate for HISD the lowest among Houston-area school districts at only…
