NSF Office Hours: Arecibo Center for STEM Education and Research (ACSER)


The National Science Foundation (NSF) hereby solicits proposals for the establishment of the Arecibo Center for STEM Education and Research (ACSER) at the original site of the Arecibo Observatory (AO). NSF seeks to evaluate proposals that would transition the existing AO site to the new ACSER, shifting the disciplinary focus from primarily on the astronomical sciences to science, technology, engineering, and mathematics (STEM) education and research more broadly. ACSER would serve as a hub for STEM discovery and exploration by building upon existing programs and opportunities currently in place at the AO site, while also creating and implementing new STEM education, research, and outreach programs and initiatives. It is envisioned as a global science, technology, engineering, and mathematics (STEM) enterprise, and a 'living lab' for inclusive and innovative experiential STEM research and education for individuals of all ages and all interests. Interactive stationary and traveling exhibitions, interpretative displays, cyber-enabled learning and engagement platforms, interactive STEM spaces or laboratories, field experiences for student and professional researchers, preK-12 school and after-school programs, and community-based events are exemplars of education, research, and outreach activities that might be supported and implemented by ACSER.
NSF will be providing several opportunities to learn more about the solicitation and site resources:
Office Hours – January-February 2023
