The Second Little Book of Joy: More Ways to Infuse Delight into Teaching and Learning
No full textThis is the second volume in a growing collection that started as The Little Book of Joy: Tiny Ways to Infuse Delight Into Teaching and Learning ( https://digitalcommons.dartmouth.edu/facoa/4352).
This second volume presents 36 new practices authored by educators and students for bringing joy into our classrooms.
As teachers, we know that a joyful learning environment helps students thrive. We know that fun is an important catalyst of-not a distraction from-the rigorous work of teaching and learning. A growing body of research supports this intuition, showing that joy helps with focus, creativity, problem-solving, teamwork, perseverance in the face of challenges, and much more. This volume provides educators three dozen concrete, actionable strategies for infusing joy into their teaching.

From Passive Observer to Co-Creator: Investigating the Role of Real-Time AI Interaction in Art Appreciation
No full textThis study investigates how real-time, Artificial Intelligence-enabled creative interaction can enhance individuals’ connection to art and their intention to engage with future art experiences. Traditional gallery contexts often position audiences as passive observers, limiting emotional and cognitive engagement. In contrast, this work examines how interactive AI systems can transform art appreciation into a more participatory process by inviting viewers to co-create alongside the original artist. A digital platform was developed to enable participants to create drawings which were blended in real time with existing artworks using Midjourney and Stable Diffusion. Thirty participants engaged with both static and interactive art conditions in randomized order. Quantitative data was collected using a mixed-methods approach, employing the User Engagement Scale, modified Differential Emotion Scale, and Technology Acceptance Model, complemented by qualitative reflections. Regression analyses revealed significantly higher engagement and emotional affect in the interactive condition. Focused attention and reward factor were significantly elevated, as were positive emotions felt during the interactive experience. Participants also expressed a greater intention to visit similar exhibitions and create art independently after the digital experience. These findings demonstrate that AI-enabled creative systems have the potential to deepen connection to artwork and creative agency within art viewing experiences
In Situ Observations of Thermal Ions in Perturbed Ionospheres: Techniques and Results
No full textPrediction and mitigation of space weather events are active research topics that require knowledge of the physics governing the ionosphere. Sounding rockets can be used to make in situ observations. The Lynch Rocket Lab created the Petite-Ion-Probe (PIP), a small retarding potential analyzer, to measure thermal ion parameters (i.e., ion density and temperature). A PIP\u27s raw data consists of a series of measured anode currents as a function of screen bias voltages, called IV curves. PIPs can be integrated onto a sounding rocket’s main payload and/or be deployed from the rocket on small platforms called ``PIP-Bobs\u27\u27. Note that as the (sub-)payload moves through the ionosphere, it charges to an electric potential which must be considered in analyzing an onboard PIP\u27s data. Ion temperature, ion density and spacecraft potential can be extracted from raw PIP data by forward-modeling Maxwellian thermal ion distributions to the PIP\u27s IV curves. Note that this method requires detailed knowledge of the PIP\u27s orientation (i.e., attitude) over time.
Perturbations to the ionosphere provide opportunities to study the governing physics. The Kinetic-scale energy and momentum transport experiment (KiNET-X) rocket mission studied the ionospheric response to sudden energy/momentum injections, in the form of ionizing barium releases. The Atmospheric Perturbations around Eclipse Path-2 (APEP-2) rocket mission studied the ionospheric response to the April 2024 eclipse, which removed then quickly returned an energy source to the ionosphere. Both missions deployed PIPs on PIP-Bobs. KiNET-X also carried PIPs on the main payload.
KiNET-X necessitated the expansion of our forward-modeling code to interpret PIP data taken inside a multi-species plasma. Additionally, a generalized code was developed to determine a Bob’s attitude over time. KiNET-X observed ambient ionosphere heating driven by ion-cyclotron oscillations from each release, and observed the injected barium’s non-ideal motion through the ionosphere. APEP-2 observed a distinct, localized decrease in E-region ion temperature as well as a lesser cooling of F-region ions. Both missions’ PIP-Bobs observed spacecraft potential variations that followed the calculated attitudes’ variations.
This thesis work illustrates the use of PIPs and Bobs for scientific studies, and provides tools for future use of these platforms for ionospheric studies
