Expansively Framing Mathematics and Computer Science Teaching With Digital Technology in Elementary Classrooms
No full textExpansive Framing (EF) is a theory and an instructional technique to facilitate connections between content and contexts. We employed EF as an approach to create a series of integrated mathematics and computer science (CS) lessons, using digital technology as a tool to leverage shared mathematical and computational ideas. We used deductive theoretical qualitative analysis of transcripts of classroom implementations to investigate how two fifth-grade teachers and one computer lab paraprofessional educator used EF during their teaching and what the EF approach looked like in practice. Findings suggested that educators engaged in EF principles when they were present in curricular materials, yet they also made additional impromptu (albeit school-based) expansive connections. The teachers in the study also regularly framed students as authors and owners of new knowledge. We recommend that mathematics-CS integrated curricular materials include language and other supports that make unambiguous, specific connections across learning contexts. We posit that EF theory can be a support to educators in the integration of mathematics and coding instruction with digital technology
It’s Time to Stop Calling People Stakeholders
Get PDFAlthough the term “stakeholder” has been widely used in science communication, recent expansion in the discourse around the negative connotations of the term necessitate that scientists and practitioners cease using the term. We discuss why this shift is necessary, how it affects our own praxis, and suggest resources for working through more respectful and just language. Looking to the science communication literature can help recalibrate terminology in positive ways
Post-Wildfire Erosion and Sedimentation: An Escalating Threat for Utah Fisheries
Get PDFWildfires are a natural part of the western U.S. landscape and provide numerous benefits, including enhanced nutrient cycling and habitat rejuvenation. Utah’s fish populations evolved with wildfire as a common disturbance. However, the increasing size and severity of wildfires, combined with Utah’s heavily engineered and fragmented stream networks, pose a contemporary risk to fish populations. This fact sheet reviews wildfire impacts on erosion and Utah\u27s watersheds and fisheries. It outlines measures we can take to prevent post-wildfire fish die-offs
An Updated Architecture for a Modular and Scalable Edge Computing System for Small Spacecraft
Get PDFSCALES (Spacecraft Compartmentalized Autonomous Learning and Edge-computing System) is a novel hardware/software system for the enhancement of machine learning onboard small spacecraft. Through the first year of development under the NASA University SmallSat Technology Partnerships (USTP) program the team has been able to design and develop the first prototype of the system.
SCALES combines the use of commercial off-the-shelf hardware and the open-source F’ software framework developed by JPL. The system is aimed at coupling radiation tolerant flight computer with the capability of high-performance edge computers. The radiation tolerant flight computer is responsible for the operation of the spacecraft and the monitoring of the edge computer, ensuring that as computationally demanding tasks are sent to the edge computer and risk to the core spacecraft systems is mitigated. Through the expansion of the F’ software framework the system will be able to support the execution and onboard retraining of AI/ML models. The goal is to enable more autonomy onboard small spacecraft by allowing more efficient data processing and system management on orbit
Hitching A Ride on History: NASA’s Space Launch System Artemis II CubeSats
Get PDFIn early 2026, NASA will launch the Artemis II mission, the second flight of its Orion spacecraft and Space Launch System (SLS) rocket. Artemis II will be the first crewed flight of the systems and will see four astronauts venture around the Moon as a key step toward establishing a long-term human presence in deep space. The 10-day flight will demonstrate NASA\u27s foundational human deep space exploration capabilities. Launching along with Orion on SLS will be four 12U CubeSats developed through partnerships with space agencies around the world that are signatories of the Artemis Accords. The CubeSats will deploy in a highly elliptical Earth orbit and will perform scientific research and technology demonstrations in space at a range of distances from Earth. This paper will provide an overview of the Artemis II mission and CubeSat payloads, as well as additional information about SLS secondary payloads
CADENCE-SWANS: Continuous Autonomous Detection Enabling Networked Collaboration Explorers of a Space Weather Anomaly Notification System
No full textThrough the University Nanosatellite Program (UNP), the Bronco Space Lab at Cal Poly Pomona presents Continuous Autonomous Detection Enabling Networked Collaboration Explorers of a Space Weather Anomaly Notification System (CADENCE–SWANS): a pathfinder mission demonstrating autonomous space weather monitoring using a low-latency, onboard radiation notification system. The spacecraft conducts coarse energy spectroscopy in real time to detect elevated radiation levels and autonomously generate notifications, including time-stamped records of detection-to-decision latency.
CADENCE–SWANS uses a novel compact, low-SWaP-C coarse particle energy spectrograph, constructed with varied thicknesses of shielding, to estimate particle energies without requiring precise pointing or expensive particle detectors. This approach enables autonomous response to radiation events in Low Earth Orbit, particularly during passes through the South Atlantic Anomaly (SAA), a naturally high-radiation region. The mission aims to validate technologies that support future distributed sensor networks—where spacecraft can detect space weather events and autonomously alert nearby satellites to take protective action. CADENCE–SWANS will also contribute radiation data to help refine SAA maps and improve radiation belt models.
This technology demonstration supports future space weather resilience for defense and commercial systems and is conducted in partnership with the Department of Defense and Air Force Research Laboratory
Developing a Full System Thermal Analysis of a CubeSat to Design a Low-Cost Battery Heater System
No full textThe Mission for Education and Multimedia Engagement Satellite (MEMESat-1) is a low-budget 2U CubeSat under development by the University of Georgia Small Satellite Research Laboratory. Once launched into LEO, the CubeSat will serve as an FM repeater for the Ham Radio community and will uplink and downlink donor-submitted images.
To verify that all MemeSAT-1 electrical components remain within their operational temperature limits throughout its lifetime, a system-level thermal analysis is performed using C&R Technology’s Thermal Desktop. This software allows for the satellite to be subjected to LEO temperatures and solar radiation, accurately simulating the amount of heat the satellite will endure throughout its lifetime.
The system-level thermal analysis determined whether hardware require thermal controls and was used to design power specifications for a battery heater which will keep the Board of Batteries (BoBa) within operational temperatures
