Hands-on experience is of utmost importance to physics laboratory experiences. Like most other schools and colleges, classes at Central Washington University had to adjust quickly to online-learning setups this past quarter. This new teaching style unfortunately pushed aside in-person interactive laboratory sessions that could have been used to supplement lecture-style videos that students watched as a part of their introductory medical physics seminar. Utilizing pre-measured data, videos, and photographs from a live clinical linear accelerator, the team at Northwest Medical Physics Center was able to create an online laboratory experience for real-time student engagement. In this presentation, the method of implementation of the lab will be discussed, along with goals for future expansion of the virtual medical physics lab program.

This educational research is about teaching electromagnetic interaction or rock formation. We use   papers showing the elementary electron-electron-photon Feynman diagrams or  sentimentation -metamorphism-melting geo-diagrams. The individual papers could be rotated, inverted, and combined to provide diagrams for any electromagnetic interaction process or rock formation. Combining orientations of single paper ,we make combinations of three or more papers.  Time is running vertically upward in every diagram. Given the opportunity to manipulate the papers, students became involved and rapidly developed understanding of electromagnetic interaction or rock formation. The students did strikingly better on the post-tests than the pre-tests.

2020 has seen a release of multiple exciting new results in gravitational wave science! In this session, we will review these latest discoveries that have opened new windows into understanding the universe. Then we will introduce teachers to activities that can be used in the classroom, both remote and in-person, to introduce secondary science students to some of the major concepts related to understanding and detecting gravitational waves, including the new results! Detectors such as LIGO and Virgo will be examined, as well as the use of Multimessenger Astronomy.

 Virtual or simulating experiments are developed and introduced by many organizations to enrich physics experiments within and beyond classrooms. Yet in the rural areas where resources are limits both physics experiment instruments and internet connection, teachers find it difficult to integrate experiments into classroom teaching activities.  We analyzed the roles and current situations of simulating experiments in high school physics teaching in China. Evaluated several current running physics experiment simulation software packages. We found PhET is suitable for redeveloping and integrating into an off-line running package, which will benefit experiment teaching in rural areas where internet coverage is poor. The paper presents the approaches of redeveloping. For the sake of generality, we use Java language and HTML language for programming, and use HTML5 technique to integrate the experiments into an off-line running package. Successful on-the-site running shows the feasibility and applicability of redeveloping PhET simulation experiment for physics experiment teaching.

Partnerships between our professional organizations and manufacturers are making it much more affordable to bring spatial light modulators (SLMs) into undergraduates' hands. SLMs are one way to shape light, in space or in time, making possible programmable dynamic holograms that actually have corporeal substance, and can play a role in faster-than-light imaging, as well as the use of entangled photon pairs (which cannot really be described as individual particles), such that the photons incident upon the detecting camera have never interacted with the object successfully imaged (which is called "ghost imaging," in reference to Einstein's concern over "spooky action at a distance"); this "spooky" result is achieved by exploiting correlations that are required by conservation of energy & momentum. — Observed phenomena of these sorts prompt students to revise their mental model of what a "particle" is!
