The National Research Council (2012) recently published A Framework for K-12 Science Education that describes a vision for science classrooms where students engage in three dimensions--scientific and engineering practices, crosscutting concepts, and disciplinary core ideas--to explain phenomena or observations they can make about the universe…

In the present study I developed and evaluated the effects of two interventions designed to target students' motivation to learn in an introductory college physics course. One intervention was designed to improve students' perceptions of utility value and the other was designed to reduce students' perceptions of cost. Utility value and cost both…

The blurring of the distinctions between pedagogy and curriculum, and experience and knowledge, has resulted in a generation of teachers who are confused about the part that each of these plays in the education of children. Schools may still teach through subjects, but there is little consensus about what constitutes a subject and what they are…

Intelligent tutoring systems (ITS), like human tutors, try to adapt to student's knowledge level so that the instruction is tailored to their needs. One aspect of this adaptation relies on the ability to have an understanding of the student's initial knowledge so as to build on it, avoiding teaching what the student already knows and focusing on…

Within the last 10 years, higher education has seen the accelerated development of blended learning (BL), active learning (AL), and STEM education. The presented mixed methods study examined a proposed framework that BL affordances enable or constrain AL, as a representation of constructivist learning theory, and that the relationship between BL…

The intent of this research is to evaluate the use of a formative assessment probe about balance and torque. The lesson was conducted with 52, 11th grade students studying in two physics classes at a state high school. A formative assessment probe was used at both the beginning and end of the study. After the students' prior knowledge about…

The learning in the physics laboratory is related to several non-cognitive variables such as anxiety which has a significant role in teaching and learning process. Therefore, university students may have different thoughts and anxiety levels towards physics laboratory class. The aim of this research was to develop a measurement tool assessing the…

The aim of the research was to know the effect of implementation of problem-based learning model on students' physics achievement and critical thinking. The research was a quasi-experimental using a pre-test-post-test control group design. It was conducted at a state senior high school in Indonesia. The data were collected by a students' physics…

This case study reports my experiences of a PhD project applying the microgenetic approach to study changes in students' conceptual structures as they developed understanding of topics in physics. The microgenetic approach involves sampling (referring to the frequency of application of data collection probes) a phenomenon at a rate which is high…

In this study we investigated how two different approaches to drawing free body diagrams influence the development of students' understanding of Newton's laws, including their ability to identify real forces. For this purpose we developed a 12-item two-tier multiple choice survey and conducted a quasiexperiment. This experiment included two groups…

The Force Concept Inventory (FCI) is a 30-question multiple-choice assessment that has been a building block for much of the physics education research done today. In practice, there are often concerns regarding the length of the test and possible test-retest effects. Since many studies in the literature use the mean score of the FCI as the…

Those who come to Cambridge soon learn that the fastest route between Harvard and MIT is by the subway. For many students, this short ride is a quick and easy way to link physics and calculus. A simple, homemade accelerometer provides all the instrumentation necessary to produce accurate graphs of acceleration, velocity, and displacement position…

A number of articles published in this column have dealt with topics in classical mechanics. This note describes some additional examples employing a smartphone and the new software iMecaProf. Steve Jobs presented the iPhone as "perfect for gaming." Thanks to its microsensors connected in real time to the numerical world, physics…

I have used many ploys to start a course in introductory physics, but one of the more interesting ones was to spend 20 minutes describing some of the curves and shapes that we would encounter in our year together. The students saw parabolas, catenaries, hyperbolas, cycloids, circles, ellipses, and helices, and were shown examples, either live or…

It's a dark, dark universe out there, and I don't mean because the night sky is black. After all, once you leave the shadow of the Earth and get out into space, you're surrounded by countless lights glittering everywhere you look. But for all of Sagan's billions and billions of stars and galaxies, it's a jaw-dropping fact that the ordinary kind of…
