In 1949, Captain Alberto Larraguibel and his horse Huaso set the world record for equestrian high jump in Vi\~na del Mar, Chile, by clearing a height of 2.47 meters, a mark that remains unbeaten. This…
Learning using Computer-Assisted Instruction (CAI) demands a high level of attention given the tendency to be distracted and mind-wander. How does the online STEM instructor know when learners are hav…
The Special Theory of Relativity, introduced by Albert Einstein in the early 20th century, marked a radical shift in our understanding of space and time. Nevertheless, the theory's non-intuitive impli…
Simple climate models have been around for more than a century but have recently come back into fashion: they are useful for explaining global warming and the habitability of extrasolar planets. The C…
Barriers to women's education and employment in Europe and the U.S. in the nineteenth century made it unlikely that any women would be among the few physicists whose ideas are taught in high school an…
Instructional labs are widely seen as a unique, albeit expensive, way to teach scientific content. We measured the effectiveness of introductory lab courses at achieving this educational goal across n…
Ci\^ensa\c{c}\~ao, an open online repository for hands-on experiments, has been developed to convince teachers in Latin America that science is best experienced first hand. Permitting students to expe…
We treat, as an illustrative example of gravitational time dilation in relativity, the observation that the center of the Earth is younger than the surface by an appreciable amount. Richard Feynman fi…
In this paper it is explained the construction and utility of a didactic exhibit about the effect of aerosol in atmosphere on electromagnetic wave propagation. The exhibit is composed by a lamp simula…
This proposal presents a methodology called enriched three-tier test, based on a similar test previously discussed in the literature. Ours consists of the use of justification and degrees of confidenc…
In this paper, we describe two paradigms in physics education research (PER): recurrence-oriented and case-oriented PER. We connect theory on research methodologies in the social sciences to interview…
This paper empirically argues for a closer examination of what we wish to retain when we speak of "retention" in engineering [1]. We present and interpret data from clinical interviews and classroom v…
OBJECTIVE: To determine public attitudes toward the use and possible limitations of assisted reproductive technology (ART).DESIGN: Mail survey based on telephone numbers selected at random by computer…
BACKGROUND: Advance care planning (ACP) encompasses both verbal and written communications expressing preferences for future health and personal care and helps prepare people for healthcare decision-m…
The unique home care environment puts nurses at risk of low back injuries. Protecting nurses may mean the difference between delivering cost-effective quality care and no care at all. This study, cond…
