A Foldscope is an ultra-affordable paper microscope with a magnification up to 2000X and 2 micron resolution. It is economic, durable and easy to handle tool for scientific studies. Many govt. schools of Kamrup district, Assam found it difficult to use microscope in their regular practical classes for its complexity and high cost. For…

Most didactic lab experiments deal with the influence of temperature, concentration, pressure, surface area, and catalysts on chemical kinetics; however, few of them explore the influence of light radiation and the presence of inhibitor agents on reaction rates. In order to investigate the effects of the radiation source and the presence of…

Technological developments allow students to access visual information from digital devices as small as phones or as large as whiteboards. Education technology research and policy typically address the software product, yet little research has focused on optimal viewing parameters or the impact it has on student users. Students with light…

For over 4 decades, educational researchers have been studying best practices for introducing writing into the curriculum. One successful strategy, a low-stakes writing exercise called "writing to learn" (WTL), has been implemented across several disciplines within higher education. In light of a growing interest in the use of technology…

This study aims to investigate textbook tasks in the Norwegian school subject Natural sciences and the views of science that the tasks mediate to the pupils. Natural science is an interdisciplinary subject taught in Years 1-11 that includes chemistry, physics, biology and parts of the geosciences. We conducted a qualitative content analysis of…

The proliferation of vast quantities of available datasets that are large and complex in nature has challenged universities to keep up with the demand for graduates trained in both the statistical and the computational set of skills required to effectively plan, acquire, manage, analyze, and communicate the findings of such data. To keep up with…

This paper reports the development and application of a low-cost multifunctional webcam spectrophotometer for the conduct of molecular absorption and fluorometric measurements. The equipment, which costs approximately US$20 to be fabricated, consists of a webcam, a diffraction grating, and a slit, all positioned inside an MDF box. Spectral…

Presents summer science activities for elementary students which focus on sunlight and other natural and artificial light sources (e.g., fire, flashlights, and fireflies). Related activities which involve language arts, art, and math are included. A reproducible page teaches children Morse Code using a flashlight. (SM)

This article sheds light on how non-formal education was used as a tool to provide knowledge and skills for Manyeledi community members who are engaged in subsistence farming, to improve their crop yield. Manyeledi is a rural village in the North-West province, which, like most rural areas, is experiencing environmental degradation caused by the…

This study traces the development of night photography, from February 7, 1839, when the effect of the moon on a Daguerreotype was first recorded by Alexander Von Humboldt, to the present. The contributions of the following photographers who advanced the field of night photography are discussed: Margaret Bourke-White, Paul Martin, Brassai, Bill…

Here we present a new undergraduate laboratory that will introduce the concepts of time-resolved spectroscopy and provide insight into the natural time scales on which chemical dynamics occur through direct measurement. A quantitative treatment of the acquired data will provide a deeper understanding of the role of quantum mechanics and various…

The excessive exposure to ultraviolet radiation, natural or artificial, is a public health concern. For this reason, it is important that, from an early age, children and teenagers gain awareness of this problem. By not being visible to the human eye, ultraviolet radiation is an abstract concept and difficult to understand, although its short-term…

The Mara-Serengeti is an ecosystem of immense importance to both Kenya and Tanzania, contributing significantly to the economies of both countries and forming a rich biodiversity reservoir. This ecosystem is among the most threatened ecosystems on the African continent. Increasing human population density and changing lifestyles have escalated…

While there are many studies on speaking anxiety in English, speaking anxiety in Turkish learned in target context remains under-examined. This qualitative study was intended to investigate the sources of speaking anxiety for foreign learners of Turkish as a second language and their coping strategies with these challenges. The data collected…

This article describes an 8-10 week problem-based learning unit for fifth graders that introduced them to the facts underlying global climate change. This unit was inspired by the lack of awareness in our national population around this clear threat to our global ecosystem and takes on this goal: to provide students (our future advocates and…
