The purpose of this study was to determine the effectiveness of a point-of-view video modeling intervention to teach mathematics problem-solving when working on word problems involving subtracting mixed fractions with uncommon denominators. Using a multiple-probe across students design of single-case methodology, three high school students with…

The Transcontinental Railroad began laying track east from Sacramento, California, in 1863 and west from Omaha, Nebraska, in 1865; the two lines eventually met in Promontory Summit, Utah, in 1869. One of the train towns, Ogallala, Nebraska, consisted of only a section house and water tank alongside newly laid track. Over the next few years, train…

Previous experiments have shown a deleterious effect of visual representations on college students' ability to solve total- and joint-probability word problems. The present experiments used conditional-probability problems, known to be more difficult than total- and joint-probability problems. The diagram group was instructed in how to use tree…

The meaningful learning of respiratory system will be enacted by students through the utilization of problem-based learning interactive media. This study aimed to develop problem-based interactive learning media on respiratory system material. This Research and Development (R&D) was conducted based on Borg and Gall with ten stages, namely: 1)…

This study investigated Turkish middle school students' proportional reasoning and provided a diagnostic assessment of their strengths and weaknesses on the ratio and proportion concepts. A proportional reasoning test with 22 multiple-choice items was developed from the context of the loglinear cognitive diagnosis model. The test was developed…

The significant global challenges faced in the world today require innovative solutions and creative thinking. In traditional postsecondary education, technical programs such as engineering often focus on technical competencies as opposed to creative thinking. However, as industry demands for creative technical employees continue to increase,…

The main objective of this article is to analyse informal learning processes in the field of video games. As many teenagers are engaged in these kinds of practices, the big question is: How do teens learn to play video games? In most cases they do not learn to play video games at school or with their parents, and therefore it is necessary to map…

Problem-based Learning (PBL) has long been touted as an effective pedagogical approach in higher education to promote students' authentic learning. As a learner-centered pedagogy, PBL is characterized by students working collaboratively in small groups to solve messy, ill-structured problems that mirror real-world problems encountered by expert…

This research is motivated by the lack of teachers' ability to use media related to the students environment as teaching materials to develop primary school students' critical thinking ability. The research aims at developing problem-based learning media (PBL) using comic book in order to improve students' critical thinking ability. The research…

Two major challenges in mathematics teacher education are developing teacher understanding of: (1) culturally responsive, social justice--oriented mathematics pedagogies; and (2) mathematical modeling as a content and practice standard of mathematics. Although these challenges may seem disparate, the innovation described in this article is…

This article introduces subversive service learning, a new type of critical service learning that shifts the locus of the "problem" from the marginalized group to the mainstream society, subverting both mainstream perspectives and the deficit model of a community being "helped." Inspired by Whiteness studies, it pursues social…

The Modeling Self-Efficacy Scale was developed to measure students' confidence in understanding and solving modeling tasks. The scale was administered to 225 eighth- and ninth-grade students. Participants read modeling tasks adapted from Programme for International Student Assessment's 2003 problem-solving assessment and rated their confidence on…

We provide context and motivation for an instructor to use real-life examples in the calculus classroom. To this end we describe two specific project ideas, one related to the devastating impact of methylmercury fungicide in a grain seed supply and the other to a catastrophic methane leak. By using calculus in contexts that have social justice…

Integral to most undergraduate psychology degree programs are research methods courses. Students learn about theory, study design and hypothesis testing, and gain knowledge that is assessed by laboratory reports. We describe a problem-based learning approach with an emphasis on acquisition of study design skills. Working in small groups, students…

This secondary analysis examined the impact of respondent-level factors on scores on the "Supports Intensity Scale--Children's Version" (SIS-C) for children and youth with intellectual disability to determine if there were any significant differences in the SIS-C scores by different respondent pairs when considering children's age,…
