Purpose This study explores student sensemaking based on the creation and interpretation of sound on a public school bus, operating as a result of a desegregation settlement. To understand these multimodal literacy practices, the authors examined students’ journeys, sonically as passengers in mobile and adult-constructed space. Design/methodology/approach As a qualitative study, the authors used ethnographic methods for data collection. Additionally, the authors used a design-based research approach to work alongside students to capture and interpret sound levels on the bus. Findings Findings from this study illustrate how students used sounds as a means to create community, engage in agentic choices and make meaning of their surroundings. Moreover, students used sound as a way around the pervasive drone of the bus itself. Research limitations/implications Research implications from this study speak to the need for research approaches that extend beyond visual observation. Sonic interpretation can offer researchers greater understanding into student learning as they spend time in interstitial spaces. Practical implications This manuscript illustrates possibilities that emerge if educators attune to the sounds that shape a learner’s day and the ways in which attention to sonic design can create more equitable spaces that are conducive to students’ learning and literacy needs. Originality/value This study demonstrates the use of sound as a means of sensemaking, calling attention to new ways of understanding student experiences in adult-governed spaces.

Magic angle intensity decay and dynamic fluorescence anisotropy measurements were made on the binary solvent system composed of ethylammonium nitrate ([N2,0,0,0+][NO3−], EAN) + methanol (MeOH) across the complete EAN mole fraction range (xIL = 0–1) using the neutral dipolar solute coumarin 153 (C153) at 295 K. Stokes–Einstein–Debye (SED) hydrodynamic theory was used as a model framework to assess the C153 rotational reorientation dynamics. Departure from stick SED prediction was observed (in contrast to literature reports that used cationic or anionic dyes) and indicated a significant influence of domain nanoheterogeneity on probe dynamics. Steady-state spectroscopy indicated minimal changes in spectral peak and width with mole fraction, except at xIL = 0.3 where absorption widths decreased by ~170 cm−1, signaling that C153 sensed a change in solution heterogeneity. Magic angle intensity decays corroborated the steady-state observation and the excited-state lifetimes showed a marked change from xIL = 0.2–0.4 where EAN-EAN interactions became notably more significant. C153 average rotation times (⟨τrot⟩) showed significant solvent decoupling with increased EAN. The rotational data were fit to a power law dependence, ⟨τrot⟩ ∝ (ηT)p, where p = 0.82, demonstrating the presence of dynamic heterogeneity in the EAN/MeOH solutions. With increased EAN, rotation times showed that the heterogeneity became increasingly more significant since the rotation times systematically decreased away from the hydrodynamic stick limit.
