Students' use of problem posing is an assessment tool for evaluating mathematical creativity, and it plays a substantial role in creative tasks. Integrating problem-posing tasks into a curriculum is beneficial for teaching and learning mathematics. The Photo-Math Project is an example of problem posing in terms of generating new problems. This…

It is often argued, rightly, that critical thinking is a necessary condition for democracy. This essay looks at the other side of that relationship, how certain democratic conditions are necessary for critical thinking to flourish. In turn, this dynamic, interactive account of democratic culture, institutions, and dispositions has implications for…

This article ponders the question: "How might EdD research methods courses be reimagined to position Black Feminist Theory as a comparable theoretical framework to guide epistemological stance development and scholar-practitioner inquiry?" By introducing Black Feminist Theory as a viable theoretical framework, this article posits its…

This study aims to examine the effectiveness of online problem-based learning (PBL) tasks on problem-solving ability (PSA) and programming skills of secondary school students. A quantitative research design of a quasi-experimental research was adopted in this study. A purposive non-random sampling method was used to select two schools. Then, a…

Previous studies have emphasised that play can promote children's learning of mathematics. However, little research has been directed towards understanding how collective imaginary play motivates children's mathematical learning. Informed by the cultural-historical conception of play and motives, this paper examines how Conceptual PlayWorld (CPW)…

Jordan canonical form (JCF) is one of the most important, and useful, concepts in linear algebra. Mathematics, physics, biology, science and engineering undergraduates often find the first application of real JCF in the discipline of differential equations (continuous models) to solving systems of differential equations. In this work, we apply…

Problem posing is an indispensable constituent of mathematical thinking, which makes it a requisite ability for students of all grades. Therefore, pre- and in-service teachers should carry out problem posing activities of high quality, and having them pose non-routine problems may be a good way to make this happen. In this context, this study…

Research demonstrates that when math-based gender stereotypes are activated (e.g., men are better at math than women), women display comparatively poorer math performance than men, a phenomenon referred to as stereotype threat. We evaluated the effectiveness of two forms of self-affirmation in reducing the effects of stereotype threat on women's…

Successful problem solving is a complex process that requires content knowledge, process skills, developed critical thinking, metacognitive awareness, and deep conceptual reasoning. Teaching approaches to support students developing problem-solving skills include worked examples, metacognitive and instructional scaffolding, and variations of these…

In today's global economy, the origin of the food we eat is becoming more and more difficult to identify. Verifying the authenticity of products to protect supply chains is a complicated problem that requires a multidisciplinary approach. Chemical authentication of foodstuffs often includes a mass spectrometer detector; however, they are costly…

The purpose of this study is to gain understanding of how secondary teachers conceptualize the relationships between mathematical modeling and problem solving. Eight secondary teachers participated in semi-structured, think-aloud individual interviews. Some conceptualizations include (a) modeling and problem solving are two distinct processes; (b)…

Contribution: This study systematically developed an educational learning framework titled "Real-world problem-posing strategy with engineering problem-solving" to facilitate engineering college students' learning. This study evaluated the effect of the developed learning framework on engineering college students' engineering…

Human bodies vary widely: height, weight, blood volume, handedness, strength, and variations from disabilities, trauma, genetics, etc. Engineers must be trained to include human variance when designing human-interactive systems. Typically, this is not incorporated into mathematical and modeling focused courses. In the spring of 2019, one of three…

A laboratory experiment was designed to provide students with an introduction to byproduct valorization by producing an analogue of biodiesel (fatty acid ethyl esters, FAEE) via lipid extraction and subsequent transesterification from spent coffee grounds (SCG). Valorization is the process of upgrading underutilized or discarded wastes or…

This research aims to describes (1) problems in planning and organizing (2) actualization of curriculum planning updates, (3) actualization of curriculum curriculum organization descriptions, (4) "Gethok Tular" word of mouth strategy, (5) description of low self-esteem or low self-esteem strategies. "Andhab Asor". The method…
