      <ActivityOrMissionDesc>The National Center for Science Education (NCSE) promotes and defends accurate and effective science education, because everyone deserves to engage with the evidence. NCSE is a not-for-profit, membership organization that helps ensure students across the country receive an accurate and effective evolution and climate science education. We do this by supporting teachers with resources and best teaching practices; through community outreach led by dedicated volunteers delivering hands-on, engaging science activities; by monitoring and mobilizing against efforts to undermine science education, whether at the statehouse or in the classroom; and by undertaking in-depth research to understand how these topics are being taught in U.S. classrooms. Our members are scientists, teachers, and citizens with diverse political affiliations.</ActivityOrMissionDesc>

      <Desc>Communications: NCSE is the go-to source for the public generally, and the news media in particular, for up-to-date information on threats to the integrity of the science classroom. In 2020, we continued to send our monthly e-newsletter to approximately 25,000 subscribers. We also sent a quarterly print publication to our members, Reports of the National Center for Science Education. The high-production, 16-page publication includes news about our programs, our members, and other articles of interest. NCSE?s work was featured in external publications such as The New York Times, Scientific American, Nature, The Washington Post, The Houston Chronicle, and The Philadelphia Inquirer. We ended the year with 165,000 Facebook fans and 17,000 Twitter followers.</Desc>

        <Desc>Breaking Down Barriers: Our community outreach program, whose goal is to create science learning in communities around the country, had to make major adjustments to its projects due to the pandemic. Once it became apparent that in-person activities were not going to be allowed, the program focused instead on its work with a cohort of graduate student outreach fellows. The fellows focused on three areas of inquiry: museum exhibits that focus on evolution, specifically genetics and evolution; the improvement of evolution and climate change education in rural museums; and the impact of an online role-playing game called Climate Change Summit that prompts participants to make decisions as townspeople on how best to spend $100,000 to mitigate climate change in their communities. The research papers generated by this work will be published in peer-reviewed journals in mid- to late-2021.</Desc>

        <Desc>Supporting Teachers: Our teacher support program, in response to the worldwide pandemic, turned its attention to developing online resources for teachers. The program published two lesson sets focused on the Nature of Science and plans to publish three more. The program also began laying the groundwork for the publication of a revised set of Climate Change lessons and a set of lessons on Evolution by enlisting the aid of NCSE's Teacher Ambassadors in development of the lessons. All three sets of lessons are aimed at helping students recognize and correct common misconceptions about the three topic areas. In addition, the program continued to send each month an educator newsletter with resources and other items of interest to more than 6,000 subscribers.</Desc>

        <ExplanationTxt>As with most organizations, NCSE needed first and foremost in 2020 to come to terms with the realities of the worldwide pandemic. Programmatically, that meant pivoting from face-to-face activities such as in-person teacher professional development and community outreach to online opportunities. Those opportunities took the form of the development of a new set of free-to-download lessons for science teachers focused on the Nature of Science and a set of resources to help students improve their understanding of the science related to the novel coronavirus. We also worked extensively with graduate student fellows to conduct research on science outreach, much of which is scheduled to be published in mid- to late-2021. Most notably, we engaged in two collaborative research efforts. We worked with the Texas Freedom Network Education Fund to develop a "report card" on the treatment of climate change in the science standards that guide what is taught in science classrooms in each state. The "Making the Grade?" report garnered a great deal of publicity from regional media, particularly in states that received failing grades. We also published initial results of a research effort on evolution and climate change education with Penn State University that began in 2019. The results helped to inform NCSE's efforts in defending and promoting the teaching of climate change and evolution, two socially - though not scientifically - controversial areas of science.</ExplanationTxt>

NCSE?s work was featured in external publications such as The New York Times, Scientific American, Nature, The Washington Post, The Houston Chronicle, and The Philadelphia Inquirer.
