|NSTA—NGSS resources||The NSTA offers a variety of resources related to the NGSS as well as forums for discussion and exchange of ideas.||http://ngss.nsta.org|
|NGSS website—Resources for Teachers||This site provides a compilation of resources designed to help teachers understand the NGSS and design instruction that supports three-dimensional learning.||http://www.nextgenscience.org/teachers|
|STEM Teaching Tools||This site has tools that can help you teach STEM. They are currently focused on supporting the teaching of the NGSS. Each tool is focused on a specific issue and leverages the best knowledge from research and practice.||http://stemteachingtools.org|
|The Teaching Channel—videos for science||The Teaching Channel has developed a number of videos related to the NGSS and instruction to support three-dimensional learning.||https://www.teachingchannel.org/videos?page=1&categories=subjects_science&load=1|
|NGSX—Learning System for Science Educators||NGSX is a Web-based professional development environment designed to engage teachers in working with the practices and disciplinary core ideas in the National Research Council report A Framework for K–12 Science Education and the NGSS.||http://www.ngsx.org|
|NGSA||The NGSA group is a multi-institutional collaborative that is applying the evidence-centered design approach to create classroom-ready assessments for teachers to use formatively to gain insights into their students’ progress on achieving the NGSS performance expectations. They are creating classroom-based, instructionally supportive assessment tasks with accompanying resources that integrate the NGSS dimensions and measure science proficiency. The tasks can be accessed through their task portal.||http://nextgenscienceassessment.org|
