In 2017, the University of Utah experienced a tragedy that accelerated already proposed changes to the physics and astronomy graduate program. This article outlines the changes made to the graduate program and discusses students' experiences with the early implementation of the new policies. In-depth, open-ended interviews were conducted with…

In this article, simple models of optical computing circuits (1 x 4 demultiplexer (DEMUX), 4 x 1 multiplexer (MUX), Boolean logic, and half-adder (HA)) are shown with mechanically controlled plane mirrors. Photographs of the proposed computational circuits are also shown. It is very useful for the school student to understand optical logic and…

Previous generations of physics students learned how common machines work, as evidenced by their textbook illustrations. Such understanding of machines that daily life depends on seems to be evaporating. In response, for two decades I have conducted an introductory physics "engine cadaver lab." It offers opportunities for hands-on…

In the epidemic period, online teaching has become the most important teaching form. On the basis of questions-centred massive open online courses (MOOCs) teaching, the online teaching mode of college physics was studied and discussed using the Tencent classroom, WeChat/QQ and Wisdom Tree Platform. MOOCs before class, Tencent classroom during…

Holistic assessment is an evaluative approach in which assessors work backwards from an overall appraisal of work to determine the criteria relevant to individual student responses. One of the strongest proponents of this approach in higher education is Royce Sadler, whose theoretical contributions over recent decades provide a strong conceptual…

North Korea's development of nuclear weapons and, more recently, intercontinental ballistic missiles (ICBMs) has added a grave threat to world order. The threat presented by these weapons depends critically on missile range, i.e., the ability to reach North America or Europe while carrying a nuclear warhead. Using the limited information available…

Since 1987, the Statistical Research Center at the American Institute of Physics has regularly conducted a survey of high school physics teachers. This September we're at it again. This fall, we will look for physics teachers at each of the 4,000+ schools with 12th grade in our nationally representative sample of public and private schools. We…

Successfully carrying out a secondary school physics inquiry requires a considerable amount of procedural and content knowledge. It further requires knowledge of how and why maintaining scientific standards produces the best available answer to the given research question. To this purpose, a series of five inquiry activities was developed and…

In recent years, the integration of science and mathematics has become popular among educators because of its potential benefits for student learning. The purpose of this study is to introduce a two-day interdisciplinary lesson that brings science and mathematics concepts together, actively engaging students in working with percentages of the…

"Mathematical modeling of the physical world should be the central theme of physics instruction" (Hestenes 1987). Science teachers know this, but because of standardized state testing, many math teachers and some science teachers feel the need to focus on memorizing facts that will be on a multiple-choice test (Volante 2004). As a…

Virtual worlds are used in many educational and business applications. At the National Technical Institute for the Deaf at Rochester Institute of Technology (NTID/RIT), deaf college students are introduced to the virtual world of Second Life, which is a 3-D immersive, interactive environment, accessed through computer software. NTID students use…

This investigation-based lesson is geared toward third through fifth grade students. The lesson presented in this article was the first of three lessons designed and taught by us for our first preservice teaching course. UTeach is a teacher preparation program for undergraduate STEM majors, which originated at the University of Austin, Texas. The…

Students and the general public are often told that the chronology of ancient events is known with high confidence, but the methods used to determine how long ago an event occurred are usually not described or even mentioned. This gives the impression that the methods are either not important or that only scientists can understand them.…

The author and colleagues have designed an Exploration Center to supplement lecture-oriented teaching in large introductory physics courses. At the center, students perform hands-on homework problems derived from lecture demonstrations. The style of exploration problems is conceptual and open ended. Methods are discussed for integrating…

Information on the influence of employment mobility and career change on the flexibility of the physics labor force is provided, noting the past several decades have brought a dramatic roller coaster of changes to the physics community. Five sections are as follows: membership composition (demographics, professional self-identification, and…
