摘要:Magnetic resonance is a quantum phenomenon and describes a resonant interaction of spins with electromagnetic fields. Its understanding requires advanced knowledge of quantum mechanics and condensed matter physics and thus often remains elusive to students. However, the great imp...

摘要:The “Energy Stick” or “Energy Tube” is an electric toy similar to an “Energy Ball.” The device is a clear plastic tube with metal foil loops on each end. When a conducting loop connects the two foil ends, a circuit is completed and current flows to activate the int...

摘要:We devised an activity to explore friction by testing some of the common theories on how ancient Egyptians moved the stones used to build the pyramids. The activity is suitable for a high school physics course or introductory college courses for both science majors and non-scienc...

摘要:While the majority of students that pursue a physics education learn mostly in a classroom setting, hands-on experiences can take their appreciation of physics to the next level. Summer internships offer just that, hands-on learning experiences and a taste of what a career i...

摘要:Item Response Theory (IRT) has proven useful in physics education research to examine the validity of concept tests (e.g., Refs. 1-3) and online homework (e.g. Refs. 4-6), yet as a tool for the improvement of physics instruction (particularly exams), it is oftentimes perceived as...

摘要:Many university and high school introductory physics courses include a laboratory portion where students follow a manual to conduct “cookbook” experiments. Here, we present an authentic research project for introductory physics students that focuses on kinematics that can be...

摘要:Researchers have shown students develop misconceptions in projectile motion for various reasons. A common misunderstanding among first-year high school physics students is the notion that the horizontal and vertical components are interchangeable in projectile motion. The st...
