We show that the gravitational acceleration g near Earth's surface can be easily determined with high accuracy by conducting the usual free fall experiment in high school or college physics laboratories. Unlike the conventional method of data analysis that uses formulas without taking air resistance into account, we consider the effect of air drag…

Purpose: Air travel is becoming increasingly recognized as a source of greenhouse gas emissions contributing to climate change. This is particularly relevant for the university sector, which relies heavily on staff air travel for domestic and international mobility. Design/methodology/approach: Using a qualitative content and textual analysis of…

Background: Household air pollution adversely affects human health and the environment, yet more than 40% of the world still depends on solid cooking fuels. The House Air Pollution Intervention Network (HAPIN) randomized controlled trial is assessing the health effects of a liquefied petroleum gas (LPG) stove and 18-month supply of free fuel in…

Thomas Graham discovered the law that bears his name while studying gas diffusion into air and other gases. He also found that the same relationship held with gas effusion, the movement of gases through a pinhole into a vacuum. Modern understanding of diffusion and effusion is based on kinetic-molecular theory, and it is generally accepted that…

The American Institutes for Research® (AIR®) has conducted an independent evaluation of the implementation and impact of the Teach For America (TFA) Rural School Leadership Academy (RSLA), a 1-year professional development program designed for two streams of aspiring and current leaders. The objective of RSLA is to recruit and provide professional…

In 2022, the Indigenous Education State Leaders Network (IESLN) and the American Institutes for Research (AIR) received a 4-year Educational Equity in Policy Implementation grant from the AIR Equity Initiative to study Indigenous student identification issues and respond to needs in the field. The Indigenous Student Identification (ISI) project…

Purpose: This paper aims to explore the manoeuvring room of higher education institutions to take action to reduce emissions from academic flying. In particular, this study investigates how university staff and central actors in university management evaluate potential measures in this area. Design/methodology/approach: The authors applied a…

The study of the motion of a projectile, thrown at an angle to the horizon, is a wonderful classical problem. This issue has been the subject of great interest to investigators for centuries. Currently, the study of parabolic motion, in the absence of any drag force, is a common example in introductory physics courses. The theory of parabolic…

In the present study, 144 second- and 150 fourth-grade Chinese students were recruited to complete a Chinese character learning task to explore the specific contributions of sensory-motor components (i.e., visual, motor, and haptic systems) of handwriting to Chinese character learning. After matching for age, nonverbal IQ, and a series of…

This article provides an example of how a television station and a teacher education program located at the University of Central Missouri partnered to provide on-air lessons for kindergarten through fifth grade lessons to respond to the academic need due to the school shutdowns in spring 2020 because of COVID-19. The article highlights how three…

This technical report provides detailed information about the sample, survey instruments, and resultant data for the 2022 American Instructional Resources Surveys (AIRS) that were administered to principals and teachers in spring 2022 via the RAND Corporation's American Educator Panels (AEP). The 2022 AIRS focused on the usage of, perceptions of,…

Type 1 diabetes (T1D) is an endocrine and metabolic disorder affecting approximately 1.4 million adults living in the United States. Psychosocial factors have been identified as key barriers to improvements in self-care among T1D adults, including emotional well-being, social support and self-efficacy, and personal motivation. It is posited that…

Inert gas manifolds for the handling of air-sensitive materials are commonplace in the inorganic chemistry curriculum as well as in research laboratories specializing in inorganic and organometallic synthesis. Mercury bubblers are ubiquitously implemented for maintaining a positive internal pressure for air-free manifold systems, commonly known as…

This study is an exploratory study, which was conducted in relation to the study of the proficiency and performance of Iranian Air Traffic Controllers: attitude, work experience, and specific Aviation English courses. Few studies have been conducted in this field. The Aviation English Courses in Iran are very similar to Content-Based Language…

America's current student demographics reflect greater diversity than ever before. With the increased enrollment of Black and Latinx students in American schools (NCES 2019), the importance of providing science students with classroom experiences embracing diversity is greater than ever. Experiences that spark an interest in Science, technology,…
