  2. A lasting impact of the COVID-19 global pandemic likely is the permanent inclusion of online learning in K–12. The rapid move to online learning left many teachers, parents, and students pining for in-person learning and highlighted major gaps in the online resources necessary for fully remote K–12 learning. But it also underscored considerable strengths of online formats for flexible learning and instruction—particularly as district capacities expanded and familiarity with online instruction increased. Many administrators now envision a permanent end to unplanned school closures (goodbye, snow days!) and long-term support for (at least intermittent) online learning. But what does continued online instruction mean for science learning, where hands-on learning is central to students’ developing skills and knowledge? Science educators implementing online instruction have faced myriad challenges, including providing effective feedback and guidance while students engaged in more independent work. We greatly respect and admire the passion and dedication that science teachers have invested in finding creative ways to implement science inquiry during online pandemic instruction. As we move beyond “emergency” remote instruction and build on shared experiences with online science teaching, it is an ideal time to rethink science inquiry online and to collectively pursue new approaches to authentic science instructionmore »with online resources.« less

  4. Abstract

    Climatic conditions exert an important influence on wildfire activity in the western United States; however, Indigenous farming activity may have also shaped the local fire regimes for millennia. The Fish Lake Plateau is located on the Great Basin–Colorado Plateau boundary, the only region in western North America where maize farming was adopted then suddenly abandoned. Here we integrate sedimentary archives, tree rings, and archeological data to reconstruct the past 1200 years of fire, climate, and human activity. We identify a period of high fire activity during the apex of prehistoric farming between 900 and 1400 CE, and suggest that farming likely obscured the role of climate on the fire regime through the use of frequent low-severity burning. Climatic conditions again became the dominant driver of wildfire when prehistoric populations abandoned farming around 1400 CE. We conclude that Indigenous populations shaped high-elevation mixed-conifer fire regimes on the Fish Lake Plateau through land-use practices.
