The increasingly widespread use of social media to expand one’s social connections is a relatively new but important phenomenon that has implications for teaching, learning, and teachers’ professional knowledge and development in the 21st century. Through a systematic review of more than a decade of educational research from around the world, we present needed insights into the state of the field in teachers’ use of social media across various platforms for their teaching in K–12 education and for their own professional learning.

This study examined the vociferous Twitter debate surrounding the Common Core State Standards during the height of state adoption in 2014 and 2015.

Teachers’ online resource-seeking behavior is influenced by their school colleagues’ online resource curation activities, as collegial connections extend from the schoolhouse to online spaces. Interesting findings show complexities regarding the network influences of three different types social capital: strong ties, “str-eak” ties, and weak ties. Teachers experience the strongest influence from their unassociated school colleagues, indicating that contextual relevance matters in seeking new resources online.
