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…

The classic experiment to measure the drag coefficient involves dropping coffee filters. Wouldn't it be more fun to try something different? In fact, an experiment on the drag force is conducted nearly 4000 times a day during the baseball season and you have free access to this PITCHf/x data!

The history of science remembers more than just formal facts about scientific discoveries. These side stories are often inspiring. One of them, the story of an unfulfilled death wish of Jacob Bernoulli regarding spirals, inspired us to look around ourselves. And we saw natural spirals around us, which led to the creation of a Hooke's…

2014 marks the 100th anniversary of the birth of Martin Gardner, a man whose writings helped inspire generations of young students to pursue a career in physics and mathematics. From his first to his last, and many in between, Gardner's publications often combined magic and science. A recurring theme was the clever use of physical principles…

The practice of teaching online and the experience of learning with e-media raise issues about time. Taking a historical approach, this article introduces three concepts of time--which physics, psychology and phenomenology characterize--and it questions their adequacy in theories of e-learning. The article argues that Heidegger's…

The traditional assignment of oxidation states to organic molecules is problematic. Accordingly, in 1999, Calzaferri proposed a simple and elegant solution that is based on the similar electronegativities of carbon and hydrogen: hydrogen would be assigned an oxidation state of zero when bonded to carbon. Here, we show that X-ray photoelectron…

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…
