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 persistent underrepresentation of women and gender minorities within the physical sciences remains a significant issue. This study investigates gender dynamics in introductory algebra-based physic…
The persistent underrepresentation of women and other gender minorities in physical science fields has been an ongoing concern. This study investigates gender dynamics in introductory physics laborato…
Artificial Intelligence (AI) has the potential to fundamentally change the educational landscape. So far, much of the physics education research relating to AI has focused on lecture-based assessment …
Determination of the Young modulus of a metal bar in the form of a cantilever is an old experimental concept. However, we have taken the advantage of modern advanced technology of smartphone camera to…
The problem-project-oriented STEM education plays a significant role in training students' ability of innovation. Although the conceive-design-implement-operate (CDIO) approach and the computational t…
Science students must deal with the errors inherent to all physical measurements and be conscious of the need to expressvthem as a best estimate and a range of uncertainty. Errors are routinely classi…
Transitions between low-lying electron states in atoms of heavy elements lead to electromagnetic radiation with discrete energies between about 0.1~keV and 100~keV (x rays) that are characteristic of …
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…
The ability to categorize problems based upon underlying principles, rather than surface features or contexts, is considered one of several proxy predictors of expertise in problem solving. With inspi…
With inspiration from the classic study by Chi, Feltovich, and Glaser [1], we asked introductory physics students in three introductory physics classes to categorize mechanics problems based upon simi…
The ability to categorize problems based upon underlying principles, rather than contexts, is considered a hallmark of expertise in physics problem solving. With inspiration from a classic study by Ch…
This paper examined how the Open Source Physics at Singapore learning community of teachers, loosing connected as creators, adapters and users, is projected to be able to self sustain, through the 3Ps…
Descreve-se neste trabalho uma proposta de curr\'iculo interdisciplinar para a forma\c{c}\~ao de professores de ci\^encias da natureza. O curso permite a obten\c{c}\~ao de quatro diplomas: professor d…
Since it was first published 30 years ago, Chi et al.'s seminal paper on expert and novice categorization of introductory problems led to a plethora of follow-up studies within and outside of the area…
In a series of well-known papers, Chi and Slotta (Chi, 1992; Chi & Slotta, 1993; Chi, Slotta & de Leeuw, 1994; Slotta, Chi & Joram, 1995; Chi, 2005; Slotta & Chi, 2006) have contended that a reason fo…
Overweight and obesity are major threats to public health in the United States, affecting more than 60% of the adult population. African-American women are disproportionately represented in the larges…
A computer-assisted education system for arrhythmia (CAESAR) was developed for students to acquire the ability to logically diagnose complicated arrhythmias. This system has a logical simulator of car…
Objectives: Motorcycle crashes are the second most common cause of road traffic injuries in Nigeria, which can be prevented through compliance with road safety measures. Compliance is defined as a sta…
AIM: This cross sectional study assessed knowledge, attitudes and practices regarding complementary feeding among mothers with children between 6-24 months at the national level.METHODS: The sample of…
