This session will show how cell phones can be used in active learning for students in physics and engineering. We will discuss some of the common apps which can be used and show examples of models which can be developed through active learning (POGIL) styled experinces for students. These cell phone sensors allow students to record, analyze and develop mathematical relationships which help to build core conceptual models in physics students at all levels.

ISTRC 2021 - International Sarcopenia Translational Research Conference

technical paper

This meeting is a great opportunity to explore sessions and workshops designed with your professional development in mind. Present your research and exchange ideas on the latest in teaching and pedagogy. Participate in a wide range of events, activities, plenaries, and so much more, connecting you with peers and colleagues who share your commitment to excellence in physics education.

We developed a board game that incorporates the rules of quantum mechanics into the game play, Quantum Party!. The goal was to create a fun and effective pedagogical instrument that could be used at the high-school or introductory college level, or even sold to the general public. We now have a professional-looking game that can be purchased online by anyone. It comes with multiple tools (dice, spinner) that replicate the science behind 4 classic quantum mechanics experiments/observations, a well as a manual that teaches both the game rules and the science behind the game, and of course, cats! Since its creation, we have run workshops with high-school teachers to brainstorm on how this can be used in the classroom. In this talk, I will give a summary of this process and where we see this going in the future.

Quantum Party! Incorporating quantum mechanics rules into a board game

Machine Learning is becoming ubiquitous in the realms of science, business, law enforcement, and even the arts. Many people don’t realize how rooted in “physics thinking” the foundations of machine learning algorithms are, but physics teachers are well positioned to teach students to use these tools and how to understand their limitations. I have developed a three-week general education course on machine learning for non-scientists, and I adapted several activities for an introductory laboratory sequence in a course on Galaxies and Cosmology. I will report on the successes and challenges of these endeavors and make recommendations on how students can be prepared at multiple educational levels to engage with the opportunities and dangers these tools represent.

Physics Teachers Should Teach Machine Learning

During the pandemic, the format of class instruction changed from in-person to entirely remote. What does a group that provides physics demonstrations to lecturers to supplement instruction do to continue to offer the same level of access to our catalog? We digitize! Working with instructors to identify their needs, we provided short videos of demonstrations performed in various ways. By using multiple cameras, professional editing software, strategic planning, and youtube we have compiled a physics demo video library accessible to the world. Here is what we learned on our journey.

Physics Demonstrations - From the classroom to the remote landscape

Quantum computing is traditionally taught with a mathematical approach, featuring linear algebra and an emphasis on proofs, two subjects not prominent in K-12 education. In this talk, we present our approach of taking QIS key concepts such as superposition, entanglement, measurement, and decoherence, and applying them to familiar situations such as tasting jelly bellies, guessing what card was flipped, and playing Connect 4. Our goal is to understand how young learners conceptualize these concepts in real-world settings, how those conceptions align and do not align with their application to quantum computing, and design instruction that both builds on their existing knowledge and bridges to quantum computing. The end goal is to delay math as much as possible in order to allow early introductions of the concepts.

Building Quantum Computing Intuition through Visuals, Activities, and Games

We present a very simple derivation of the commonly used approximate formula [1]: D = A * sin ((d/365.25) * 2*PI), where D is solar declination, A = 23.44 deg is Earth's axial tilt (obliquity of the ecliptic), and d is the number of days after Equinox. We used the heliocentric cartesian frame of reference with XY plane coplanar to the ecliptic. We analytically calculated the scalar product of the unit vector pointing from the Sun to the Earth and the other unit vector pointing from the Earth to Polaris. This product is equal to the cosine of the angle complementary to the solar declination D. We also demonstrated how we can find the geographic latitude using hands-on observation of the shadow of a yardstick at local geographic noon. The geographic latitude is found with the accuracy of about 1.5 degree (or 100 nautical miles along meridian).

The Approximate Formula for Solar Declination and Its Experimental Validation

Space exploration is a naturally interesting topic to many people. With the advances in spacecraft propulsion methods, it is possible for humans to study distant celestial bodies. Students can investigate the benefits and challenges of both human and non-human travel to space through different means. In this study, we investigated ways to help students understand space exploration. Two activities, Migration to Mars and Solar Sails, were designed for an undergraduate astronomy course taught online during the COVID pandemic. Students completed the activities in groups of four. One activity per group was submitted to the course management software followed by a quiz that students answered individually. Quiz responses were coded to check students’ understanding of the activities and the extent to which they were able to describe information relevant to space exploration. Students generally understood the value of uncrewed missions and the fact that solar sails use sustainable energy.

Students’ Understanding of Factors Related to Space Exploration

Investigating the physics of music is a reliable way to engage many of your students. A sonometer is a traditional device for learning about the physics of string instruments. The new PASCO sonometer adds new features to this classic experimental apparatus. These features make it quick and easy for students to gather the data they need to answer questions about wave properties, resonance, and standing waves in strings. The PASCO sonometer can be used with modern sound sensors and FFT analysis to measure frequency or "old school" with tuning forks. This presentation will introduce the new PASCO sonometer features, explain how to use it to collect data, and describe several experiments that can be performed with it. Student handouts and teacher guides will be provided.

Experimental Inquiries with the New PASCO Sonometer

The Drop Tower at Portland State University allows investigations of the behavior of physics demonstrations when the acceleration due to gravity goes to zero for 2.1 seconds. Does this cause a chaotic pendulum to transition into non-chaotic behavior or does chaos survive this short transition into weightlessness due to being in a non-inertial frame of reference from free fall? This question will be answered by viewing one of the many demonstrations in the Drop Tower Physics YouTube Channel, and the theoretical reason for this behavior will be discussed.

Chaotic Pendulum in Free Fall

Did you know? Half of STEM majors are interested in teaching as a profession, and STEM students of color are more interested in teaching as a profession than their White counterparts. If we want these students to consider majoring in a STEM field, it is important to include teaching as one of their career options when entering the major.&nbsp; In this presentation we will share updates on the Get the Facts Out Project including data to support the above claims, new handouts with salary and cost-of-living information for teachers in hundreds of school districts, a new professionally made short video series, and new single-slide conversation starters. We will also share what we learned from a GFO half-day mini-conference where we heard from faculty in physics, chemistry, and mathematics about what they would like to see from GFO in the future.

Increasing the Number and Diversity of Majors by Advertising Teaching

Kudu.com is a web-based online platform that provides customizable textbook content, engaging videos, and auto-graded online homework questions. Homework questions can be used to conduct live clicker sessions where students use phones, tablets or laptops to respond as instructors see instant results. Instructors can add their own questions and access questions uploaded by others. They can edit the content, sequence, and structure of the text and embed additional videos and links. Up to now Kudu courses were used only by universities like UCLA and UC San Diego. A new AP Physics 1 course was added this year and is free for high school instructors and students to use. Skeptical? Kudu.com guarantees the AP Physics 1 course will remain free in perpetuity. This presentation will go into detail about the AP Physics 1 course's features and how to access and use them.
