Using a randomized controlled trial, we examined the effect of a fractions intervention for students experiencing mathematical difficulties in Grade 5. Students who were eligible for the study (n = 205) were randomly assigned to intervention and comparison conditions, blocked by teacher. The intervention used systematic, explicit instruction and…

This study aims to conceptualise a drama-integrated curriculum devised from process drama as an approach to play-based pedagogy and curriculum to realise the policy initiative of learning through play. By investigating teachers' perspectives and practices in relation to the curriculum of a local kindergarten, examples of effective…

Cognitive difficulty arises from two types of cognitive processes: treatments; within the same, conversions; between different types of representational registers. Conversions are difficult since they ask for understanding of two representations. Direction and the choice of first register could be a threshold for the student. Wasan geometry is…

Computational thinking (CT) can be considered a 21st century core skill and, accordingly, it should be taught to students at an early age. Nevertheless, the implementation of CT in school curricula is still in an experimental stage, given that different performance metrics remain unclear, including the appropriate age for learning each skill, the…

The acquisition of procedural and conceptual knowledge is imperative for the development of problem solving skills in mathematics. However, while there are mixed research findings on the relationship between the two domains of knowledge in some branches of mathematics, the relationship between learners' procedural and conceptual knowledge of…

Tinkering is often viewed as arbitrary practice that should be avoided. However, tinkering can be performed as part of a sound reasoning process. In this ethnomethodological study, we investigated tinkering as a reasoning process that construes logical inferences. This is a new asset-based approach that can be applied in computer science…

Learning to solve arithmetic word problems is an essential part of the primary school mathematics curriculum. The success of word-problem solving was previously found to relate to reading comprehension ability of children. However, the relationships between specific reading comprehension component skills and word-problem solving remain largely…

Universities and scholars around the world teach and research extensively in the field of peace education; yet, despite a plethora of diverse scholarship, educational programs are often critiqued as dominated by the English-speaking world. This paper employs the intersecting lenses of decolonization and postcolonial theory to explore and challenge…

As consultants who infuse the "Habits of Mind" into schools, the authors explain how spreading these habits through school can increase the whole school's well-being and feed teacher efficacy. They list seven factors that can create a "culture of efficacy" that draws on these 16 habits (thinking dispositions at the core of…

The Pearson correlation coefficient can be recovered from the two least squares regression lines y[with circumflex] = b[subscript 0] + b[subscript 1]x and x[with circumflex] = a[subscript 0] + a[subscript 1]y without any data. This can be done both algebraically and geometrically. This can be done without data even when the scales of the variables…

Today's workplace is going through tremendous changes and becoming highly complex in terms of technology and tasks. Thus, critical problem-solving skills are key to creating a sustainable career in today's global economy. Indeed, the global COVID-19 epidemic has amplified the need for these skills in almost all occupations. This study examined the…

The simple vehicle routing problem (VRP) is a common topic of discussion in introductory operations research/management science courses. The VRP can be framed in a variety of ways, and it can be difficult to solve to optimality. For solution purposes, introductory textbooks demonstrate how Excel's Evolutionary Solver (ES) add-in produces a…

This paper reports on a project that sought to enhance problem-solving practices within a cluster of primary schools. In-service teachers' description of their approach to problem-solving suggested it was treated as an isolated practice that occurred after concepts had been taught; often focusing on teaching particular problem-solving strategies…

Numbers and variables often follow the same principles of arithmetic operations, yet numbers can be computed to a value whereas variables cannot. We examined the effect of symbols--numbers versus variables--on middle school students' problem-solving behaviors in a dynamic algebra notation system by presenting problems in numbers (e.g., 3+5-3) or…

Today's students will face issues and problems that are global scale and require a collaborative global effort to resolve effectively. To help prepare students to resolve these global issues, students must learn to participate in the global democratic process as part of their citizenship education. In particular, scholars argue students need to…
