Critical thinking is acknowledged as a 21st century skill that allows humans to make considered and informed decisions based on the information available them. Studies exploring critical during early years are of particular significance because they enable researchers refine general view situate it in context young children. Current opinion regarding founded international research various fields, including primary secondary education, higher education institutions industry. This paper...
We present a measurement of ν_{e} interactions from the Fermilab Booster Neutrino Beam using MicroBooNE liquid argon time projection chamber to address nature excess low energy observed by MiniBooNE Collaboration. Three independent searches are performed across multiple single electron final states, including an exclusive search for two-body scattering events with proton, semi-inclusive pionless events, and fully inclusive containing all hadronic states.

Abstract In the last two decades, there has been a global movement towards pedagogies that create more inclusive school environments in order to meet needs of diverse learners. One such approach is Universal Design for Learning (UDL), which foregrounds design flexible and accessible learning experiences all, regardless learner characteristics. Technology key enabler this. To date, much research on UDL focused its impact higher education, with less evidence available use within second‐level...
