Retouching of school photos is going beyond simply removing glare from students' glasses to include teeth whitening, removing freckles, and other adjustments to students' appearance. Todd Pittinsky argues that schools should not include these kinds of services as part of their photography options because they send a message to students that their…

The camera obscura is a well-known optical device in the form of a closed box with a hole in one of its walls through which light rays pass, forming an inverted image of the external objects on the opposite wall, as can be seen in Fig. 1(a). Despite the simplicity of its basic design, they have been widely used by scientists and artists. In…

The Holocaust was one of the most photographed genocides of the twentieth century. Since 1945, images from the liberation of the camps were used as shaming and shocking instruments of visual denazification. Many decades later, these icons are still used in educational contexts such as school textbooks, exhibitions, and documentaries and are…

Traditionally, informative speeches are relegated to be passive. The classic scope of informative speeches does not consider "live" or "lived" rhetoric. After teaching public speaking for most of my career, there are times when one needs to reinvigorate assignments. This assignment challenges how we utilize memory and place to…

Broadly, this article details the imbrication of a Black feminist qualitative researcher's onto-epistemology and data (meta-) analysis process. I theorize "Black feminist memory work," then apply this method by returning to data I collected for a completed research project and meshing those data with a curated selection of thematically…

This short take explains how we developed a photographic guide for assessing biodiversity in food consumption studies with taxonomy accuracy. To build the guide, we followed the "Guidelines on Assessing Biodiverse Foods in Dietary Intake Surveys" of the Food and Agriculture Organization (FAO) of the United Nations. As far as we know,…

A smartphone is a powerful learning aid in the hands of a large section of students around the world. The camera of the phone can be used for several learning purposes apart from its obvious purpose of photographing. If the focal length of the lens of the camera can be determined, several experiments in optics can be performed with it. In some…

Over a period of 13 years, I taught a class in photography to high school students, using a taxonomy I developed based on my own understanding of what makes for excellence in photography. Five of the elements of this taxonomy are explained and illustrated by photographs taken by my students; I submit these as evidence of my success in this…

In this article, Sohyun An presents a lesson that she was invited to teach at an elementary school in Georgia for the celebration of Asian American and Pacific Islander (AAPI) Heritage Month. As a social studies teacher educator and mother of Asian American children attending the school, she has worked with some of the teachers to advance critical…

In this study, we propose a novel and direct method of determining the focal length of a converging or diverging lens using a smartphone. The standard optical sensor used in modern smartphone cameras is an active-pixel sensor called the complementary metal-oxide-semiconductor (CMOS). The CMOS is covered by an assembly of five to seven camera…

We demonstrated that an optimally designed pinhole camera can be used as an astronomical tool to observe the libration and apparent diameter change of the Moon at night. The libration and apparent diameter change of the Moon were observed using a handmade pinhole camera with a diameter of 0.65 mm and a focal length of 400 mm. It was found that the…

Thermal cameras have shown to have utility in secondary school classrooms and undergraduate courses. In this paper, the author argues for their potential in the primary school classroom and presents a range of activities that can be undertaken with thermal cameras (or supplied images). With limited access in mind, the activities in this paper have…

The pandemic challenged many of us as researchers, requiring that we reflect upon our methods and make modifications to allow for online facilitation. As researchers who traditionally use Participatory Research Methods (PRMs), we were significantly challenged, to reflect on our approach and the ways in which we may remain true to the spirit of…

Practical experiments enhance students' understanding of basic concepts and promote deep learning experiences in chemistry. The smartphone application of Lab4Chemistry was utilized to replace colorimeters with smartphone camera sensors. Low-cost and readily available materials, including anthocyanin (fresh red cabbage) and common kitchen…

This research focuses on the survey and study of building architecture built in approximately 1932-1992, in Nakhon Nayok Province, Thailand with the three research objectives: (1) to study modern architecture buildings in Nakhon Nayok that reach the criteria of modern building value for conservation and lifelong learning, (2) to create a roster of…
