The Next Generation Science Standards (NGSS) require teachers to think very carefully about the structure of lessons, which content must be taught to allow students to achieve NGSS expectations, and how content is delivered. With the standards' focus on three-dimensional learning and the use of relevant phenomena, most teachers are urged to make…

Electric potential is one of the most challenging concepts taught in high school physics classes due to the abstract nature of the concept. When taught, electric potential is often taught using a poorly triangulated set of instructional analogies, each possessing different strengths and limitations. Within this paper we share our learning from a…

I begin my introductory astronomy course with a unit on critical thinking that focuses on, among other things, the differences between the "scientific method" as frequently presented in textbooks and actual scientific practice. One particular classroom activity uses a simple dice game to simulate observation of a natural phenomenon and…

Recent and exciting discoveries in astronomy and cosmology have inspired many high school students to learn about these fields. A particularly fascinating consequence of general relativity at the forefront of modern cosmology research is gravitational lensing, the bending of light rays that pass near massive objects. Gravitational lensing enables…

Wireless communications are ubiquitous. Students and teachers use iPhones[R], BlackBerrys[R], and other smart phones at home and at work. More than 275 million Americans had cell phones in June of 2009 and expanded access to broadband is predicted this year. Despite the plethora of users, most students and teachers do not understand "how they…
