The purpose of this mixed methods study was to investigate the implementation of a researcher-created numberless word problem instructional unit designed to introduce second-grade students to word problems in the semantic category of "compare with the word more, smaller unknown." The 10-day instructional unit incorporated three elements:…

This paper describes a study in which five physical science teachers were requested to take photographs and describe the science concepts embedded in these. Particularly, the science had to be relevant to the grade 10-grade 12 curriculum they were teaching. This study was an exploratory case study employing qualitative methods. To analyze data…

Visualizations have become more complex in recent years so that users need to learn how to use these systems. Onboarding systems can help users to learn how to interact with a visualization efficiently. Simple tutorials are often not sufficient. There are still open questions on how to design such onboarding systems. So far, a few usability…

This qualitative, multiple case study provided comprehensive descriptions of the conceptual difficulties and learning experiences of in-service teachers as they improved their ability to effectively model fraction division with pictorial diagrams. Video data were collected on eight teachers as they individually progressed through a professional…

This study measured the effectiveness of sight word practice using flashcards and the growth results were compared based on presentation formats when administered to a group of second grade students. The data were later disaggregated to compare the success rates of each platform among three different subgroups within the test population, based on…

As our world is increasingly filled with data visualizations, having the skills to leverage data visualizations is essential for participation in society. Confident engagement with data visualizations is critical for being an educated member of society; however, research has shown that it is difficult for individuals to digest and gain meaningful…

Literacy skills play a crucial role in the ongoing education and social interaction of children diagnosed with Autism Spectrum Disorder (ASD). For instance, the ability to read serves as an essential basis for their academic accomplishments, and higher academic achievements have been shown to lead to improved employment prospects and financial…

pH buffers are used extensively in research and industry making them an important chemistry topic for students to learn. This qualitative study uses the phenomenographic method and a resource theoretical framework to provide the first insights into how students approach conceptual buffer problems. Three scaffolded buffer question sets were…

There is a new "genre" of literature that is aimed explicitly at adults and children, or sometimes simply at adults, which follow the formula of the picture book: the inclusion of a simple text accompanying provocative images, and sometimes images alone. On the surface they may seem best suited for the "children's section" of a…

The constant dehumanization of Black fathers and boys in the media, education, politics, pop culture, and society is traumatic. Deficit perspectives and a racialized political climate often negatively portray the moral, familial, and relational practices that Black fathers and boys engage in with their family members in their homes. Using…

Qualitative studies in the domain of physics education research have become more common in the last several decades. Methodologically, this has been marked by an expansion of the types of data collected in physics education research (PER): namely, in the use of individual and group interviews, problem-solving sessions, and classroom…

Augmented reality (AR) filters are digital interactions applied to users' faces or environment to add to or change what they are seeing in the real world. By using free software, it is possible to easily make many AR filters for learning chemistry. Here I show how to make AR filters of molecular models and post them on social media in just two…

Approximate mathematical treatments are commonly taught in undergraduate chemistry, but the validity ranges of these approximations have rarely been properly defined. We present error contour plots of commonly used quadratic approximations for calculating equilibrium proton concentrations of monoprotic acids. Students and instructors can easily…

This article pushes forward a critical dialogue about the value of visualization as a method of sociological theorizing. Building on a nascent literature, I argue theory diagrams may operate not only conjunctively but also disjunctively, independent from empirics; that their theoretical value lies not only in capturing sociological problems but…

PowerPoint is one of the most widely used technological tools in educational contexts, but little is known about the differences in usage patterns by faculty members from various disciplines. For the study we report in this article we used a survey specially designed to explore this question, and it was completed by 106 faculty members from…
