Welcome to the Collaboration Hub for the Science 20/20 project, a community–school–university partnership working to provide meaningful science learning and language development opportunities for every child.


Science 20/20 is a National Professional Development grant funded by the Department of Education, Office of English Language Acquisition. The project’s name is a play on 20/20 vision – drawing attention to the importance of bringing English Learners into focus inside and outside of school settings. The project brings together practicing and preservice teachers, community educators, parents, and teacher educators for the purpose of co-developing shared practices and resources for supporting language learning through next-generation science teaching and assessment. Collaborators in this community–school–university partnership includes the community of Hazleton, faculty, and administrators from Hazleton Area School District, College of Education faculty and graduate students from The Pennsylvania State University (UPark), and Hazleton One community center.

The conceptual framework that guides the work of Science 20/20 promotes instruction that is responsive, inclusive, and consequential for every child. Scientific and engineering practices are integrated with literacy and language development practices around three intersectional constructs – knowledge building, productive participation, and formative assessment.

The Science 20/20 OER Hub serves as the platform for co-developing, disseminating, and refining video-based cases of classroom practices, resources, and tools for robust and equitable science instruction and assessment, and interactions within and between collaborative teams.

If you are interested in the work and/or use some of the resources housed here, please help us extend our learning community by sharing your feedback and insights with us.

Science 20/20 Collections are organized into three complementary categories of resources: SEE IT, EXPLORE IT, and BUILD IT.

SEE IT is a library of video-based cases that provide “images of the possible” of three-dimensional science teaching from elementary classrooms.

EXPLORE IT provides resources for the instructional practices highlighted in the video library. These resources are intended to make teachers’ thinking and decision making visible, especially as it relates to supporting ELs.

BUILD IT provides tools and templates for educators to use when constructing their own version of the instructional practices highlighted in the video library and/or “remix” examples authored by other teachers to better align with the needs of students in particular contexts.

If you are new to the Science 20/20 Hub, we suggest you begin by browsing the instructional videos in the SEE IT collection.
