  1. Over the last three years, we have worked in a research practice partnership (RPP) between a research non-profit and three school districts to establish system-wide K-12 pathways that support equitable participation in computational thinking (CT) that is consistent across classrooms, cumulative from year to year, and competency-based. Reflecting on the work done over the last three years, we have identified tensions related to ambition and specificity within our RPP and the development, implementation, and spread of inclusive computing pathways. Ambitions can waver between grandiose upheaval in curriculum and classes and the identification of CT solely in what is already happening.more »While it is relatively easy to adopt and spread programs that propose modest change, these programs are not necessarily worth an investment nor do they produce CT skills in alignment with the district's overall vision. Similarly, the specificity in which computational thinking is operationalized can teeter between prescriptive lesson plans and broadly-stated curricular standards. Vague initiatives are difficult to implement, but teachers are also resistant to overly prescriptive programs. In this paper, we explore these tensions balancing ambition and specificity using examples from our partner districts. Drawing on our experiences co-designing the inclusive computing pathways as well as interviews with and open-ended questionnaire responses from our district partners, we discuss implications related to these issues and the ongoing tensions around ambition and specificity that need to be considered and overcome in terms of meeting the national call to develop more inclusive computing pathways for schools and districts.« less

    Abstract The Deep Underground Neutrino Experiment (DUNE), a 40-kton underground liquid argon time projection chamber experiment, will be sensitive to the electron-neutrino flavor component of the burst of neutrinos expected from the next Galactic core-collapse supernova. Such an observation will bring unique insight into the astrophysics of core collapse as well as into the properties of neutrinos. The general capabilities of DUNE for neutrino detection in the relevant few- to few-tens-of-MeV neutrino energy range will be described. As an example, DUNE’s ability to constrain the $$\nu _e$$ ν e spectral parameters of the neutrino burst will be considered.
  3. Abstract The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a combination of capable precision detectors, and by the massive far detector system located deep underground. This configuration sets up DUNE as a machine for discovery, as it enables opportunities not only to perform precision neutrino measurements that may uncover deviations from the present three-flavor mixing paradigm, but also to discover new particles and unveil new interactions and symmetries beyond those predicted in the Standardmore »Model (SM). Of the many potential beyond the Standard Model (BSM) topics DUNE will probe, this paper presents a selection of studies quantifying DUNE’s sensitivities to sterile neutrino mixing, heavy neutral leptons, non-standard interactions, CPT symmetry violation, Lorentz invariance violation, neutrino trident production, dark matter from both beam induced and cosmogenic sources, baryon number violation, and other new physics topics that complement those at high-energy colliders and significantly extend the present reach.« less
