Incandescent lamps are not only good sources of electromagnetic energy radiations but their operating temperatures are comparable to the temperatures of stars also. These features can be exploited to teach apparent magnitude scale both theoretically and experimentally. The numerical illustrations presented corresponding to 10, 100, 1000 and 10 000…

Time-resolved luminescence lifetime measurements are an important photophysical technique. However, access to this technique at the undergraduate level is limited by the expense of the instrumentation needed to create the well-defined light pulses required to measure the luminescence decay of an excited state molecule. We present here an…

The California Blackworm ("Lumbriculus variegatus") is a freshwater segmented worm species that has been used by biology instructors as a model system for inquiry-based student investigations. The blackworm dorsal blood vessel pulsation rate is easily quantified. Moreover, this species can facilitate the study of neuromuscular…

Electric potential is one of the most challenging concepts taught in high school physics classes due to the abstract nature of the concept. When taught, electric potential is often taught using a poorly triangulated set of instructional analogies, each possessing different strengths and limitations. Within this paper we share our learning from a…

The purpose of this study was to develop and validate study e-content in teaching and learning of automobile lighting system in technical colleges in Niger State, Nigeria. The study adopted Research and Development (R&D) design. The researchers modified the 10 steps of R&D model to 5 steps cycle which fits the present study. The five…

In 2017, almost everywhere in the world, there was a boom in sales of fidget spinners. A toy that has 'multi-lobes' that can rotate freely from a thrust performed with the fingers. Thereby, we analysed the physics concepts that involved in this toy, such as angular and linear velocity. We did the analysis using the software Tracker, a laboratory…

Asynchronous video-based educational resources allow for increased course material engagement. In today's climate, educators are encouraged to create videos for online instruction but are typically given limited production guidance. Few formal resources exist to guide educators for high-quality video production in a non-studio setting. This…

A prelecture video can be made more engaging with a lightboard. With this method, an instructor presents material in a video while directly facing the camera and writing on a transparent screen in front of them. We present instructions for constructing an inexpensive removable desktop lightboard that can be stored as smaller pieces. We share tips…

Multiage, child-size, and accessible, the Montessori classroom provides a prepared environment that maximizes self-regulated activity. Designed to be intuitive and conducive to children's development at multiple developmental planes, the classroom nurtures each child's growing independence. Ideally, the principles underlying the Montessori…

In the learning process, it is accepted that learning with entertainment is important in participation in the process and retention of learning. Thus, the aim of the present study was to investigate the views of students and teachers on entertaining and boring settings in the learning process. Phenomenography method was used in the study. The…

The likelihood of teaching a student with autism spectrum disorder (ASD) has steadily increased over the past two decades. However, the practical information about working with students with ASD has not increased at a similar rate. Teachers may therefore be unaware of simple modifications they can make to their classrooms to meet the needs of…

We safely remove the outer glass bulb from an incandescent lamp and burn up the tungsten filament after the glass is removed. This demonstration dramatically illustrates the necessity of a vacuum or inert gas for the environment surrounding the tungsten filament inside the bulb. Our approach has added historical importance since the incandescent…

Several papers in this journal have dealt with the fluorescence in orange neon plastic, olive oil, and soda. In each case, the fluorescent emission was excited by either green or violet-blue laser light. In this paper, we examine the fluorescent emission spectra of so-called neon colored papers and plastic clipboards available in department and…

A descriptive case study with multiple data collection methods was carried out to understand how online graduate students identify the characteristics of their physical learning environment. Equivalency theory and the science of ergonomics framed the study. Participants were 10 online graduate students, all working adults (60% female, most between…

This research was a quantitative case study on the possible relationship between school climate, student behavior, student achievement, and classroom facility factors in an urban Midwest high school. Specific variables included lighting, wall color, classroom temperature, school climate, student behavior, and student academic achievement. The…
