In traditional introductory physics courses, concepts of distance, displacement, speed, velocity, scalars, and vectors are generally taught near the beginning of the course. However, students often contend with preexisting notions, such as the idea that speed and velocity are synonyms, which present some of the first conceptual hurdles that they…

In the past decade, we have witnessed the emergence of a large number of different computer-based animations and simulations that have the goal to foster better learning of different physics topics. Past studies have shown many benefits of animations and simulations, but for their efficient usage it is very important that teachers are well…

The nature and cause of the phases of the moon are widely misunderstood. Perhaps the problem is a general decline in scientific literacy, or maybe it is the loss of direct and regular observation of the moon in society generally. Many people do not see the moon as a half-illuminated sphere. Adults are often surprised to realize that the moon can…

The floating and sinking phenomenon related to buoyant force can readily be observed in everyday life and easily demonstrated to young students. However, many students believe that the buoyant force is determined by the object's attributes, such as the shape (e.g., ship) or material (e.g., wood). As a result, students find it challenging to…

Research in physics teaching has supported the use of analogies as an effective instructional tool that can be used to facilitate students' understanding of physics concepts. The effectiveness of analogies lies in that they allow students to form cognitive links between what they already know and what they are learning, harmoniously integrating,…

The success of films such as "Avengers: Endgame," "Black Panther," and "Captain Marvel" has established the superhero genre in modern popular culture. Many students will have seen these films, or at the very least they are familiar with a number of the superhero characters. In the physics classroom, content based on…

For many students, introductory physics is an enormous hurdle to cross in their educational careers. Studies show that many students struggle with basic vector concepts and hold misconceptions of fundamental principles like Newton's laws, ideas essential to the understanding of higher-order physics concepts and for achieving success in engineering…

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 (a) mysterious, (b) unjustified, and (c) impractical. This article…

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 students' incorrect reasoning is connected to their personal experiences…

Throughout students' careers in physics, there are some topics that they learn multiple times and in multiple ways, and other topics that are briefly, if at all, discussed. I wanted to have the students think about all of the different physics topics they had learned in, most likely, a new way. Games have been used as a way to learn new physics…

Addressing student conceptions with instruction has been a major issue in physics education for decades. However, too often the focus is on treating student ideas as "misconceptions" rather than as potentially productive ideas with varying degrees of sophistication. This paper introduces "learning progressions" as models that…

In fall 2014 we started the development of a series of short YouTube videos to help our introductory physics students better comprehend concepts they tend to find challenging. Our work is inspired by the PhD thesis of Derek Muller (author of the Veritasium channel) showing that lecture-based videos tend to be not only ineffective, but actually…

A number of papers in this journal have dealt with the idea of using hooks in physics instruction. A hook, as the name suggests, engages students in learning by triggering their attention and interest. Hooks can be any type of pedagogical approach--a question, a demonstration, a puzzle or video. They are generally short and center on the most…

"MythBusters," the long-running though recently discontinued Discovery Channel science entertainment television program, has proven itself to be far more than just a highly rated show. While its focus is on entertainment, the show employs an array of pedagogical techniques to communicate scientific concepts to its audience. These…

Some misconceptions about physics are hard to change. For example, students continue to believe that heavier objects fall faster than light ones, even after a year of physics instruction. Physics misconceptions are persistent. Light objects do fall more slowly if their size-to-weight ratio is sufficient for drag to be appreciable. Motion through a…
