Worldwide interest in Lesson Study (LS) and the opportunities offered for student learning through the use of a Structured Problem-Solving Approach (SPSA), as typically adopted in Japanese LS research lessons in mathematics, have left largely unanswered questions about the extent to which these can be replicated elsewhere. This paper presents a…

This study aimed to reveal a relationship between high school students' 21st-century skills and academic performance in mathematics and science courses. The research was designed in a relational survey model. In the study group, there were 596 students. Descriptive statistics, the one-way analysis of variance, the Pearson correlation test, and…

This paper introduces a model built upon the Method of Varying Inquiry, offering a didactical approach to problem posing and solving activities that stimulates inquiry-based learning in mathematics classrooms. The model combines the inquiry-based framework with the variation theory and with specific didactical and theoretical elements (the…

This article introduces unit transformation graphs (UTGs) as a tool for diagramming the ways students use sequences of mental actions to solve mathematical tasks. We report findings from a study in which we identified patterns in the ways preservice elementary school teachers relied on working memory to coordinate mental actions when operating in…

Although student academic support programs have dated back to Early Colleges in America, the way we service our students' populations has had to evolve. Various student support programs have been utilized over the years, and while at that current time may have indicated benefits, are now outdated. One service that is demonstrating success is…

Problem-solving has been playing an important role in predicting students' academic achievement, cognitive skills, and future careers. It plays an even more important role in English learners (ELs), especially those who are at-risk for math learning difficulties, because they face more severe challenges in language. As more English learners…

Children's arithmetic performance is dependent on the arithmetic task format, but little is known about how domain-specific and domain-general abilities contribute to solving diverse arithmetic problems. In this study, 145 Italian typically developing children between the ages of five and six, who have not yet received formal schooling, were…

Programming is an interdisciplinary practice with applications in both mathematics and computer science. Mathematics concerns rigor, abstraction, and generalization. Computer science predominantly concerns efficiency, concreteness, and physicality. This makes programming a medium for problem solving that mediates between mathematics and computer…

Achievement gaps in mathematics between middle and high school Black students when compared to their white peers exist in part because of access, but also because Black learners' brilliance is not recognized. Finding ways to help students, especially Black students, become successful mathematical problem solvers was a driving force behind this…

In this study, we investigated the connections among teacher-student relationships (TSRs), intrinsic motivation, self-efficacy, and non-routine problem solving (NPS) in mathematics with a moderated mediation model. A sample of 3,101 Chinese ninth-graders (1,654 urban students and 1,447 rural students) participated in a large-scale survey. The…

In this article, the authors explore how the 3C Model can be used to integrate other curriculum areas with mathematics, namely digital technologies. To illustrate the model, they provide a practical example of a teaching sequence. T he 3C Model is designed to create opportunities for applying reasoning and problem-solving skills and learning…

Affect has been identified as one of the important inputs in illuminating the mechanism of cognitive activities in mathematical problem solving (MPS). This study aimed to assess upper primary students' MPS-related affect with a focus on its differences across gender and grade-level among upper primary students. To do so, a simple Likert type scale…

This paper illustrates how years 1 and 2 students were guided to engage in data modelling and statistical reasoning through interdisciplinary mathematics and science investigations drawn from an Australian 3-year longitudinal study: "Interdisciplinary Mathematics and Science Learning" (https://imslearning.org/). The project developed…

Studies have shown that learning mathematics through programming can be complex and that the programming itself might even hamper students' learning. However, few studies have focused on the role of the teacher and the teacher-student interaction that aims to support students' learning when using programming. The present study examines a didactic…

This study was guided by the question, how do we understand the multiplicative reasoning of upper high school students and use that to give insight to their performance on a standardized test? After administering a partial ACT assessment to a class of high school students, we identified students to make comparisons between low and high scoring…
