The slideshow "Social Media Use for Professional Learning Networks" is on how to use social media to create professional learning networks. This was presented at the "The Social Science Teacher" workshop session, NSTA Chicago 2015 conference.
A 'professional learning network', is essentially personalized professional development -- PPD! It's an online community that you create for yourself in order to get the support that you need. It's completely teacher-driven.
The presentation goes over the purpose of a PLN and the five basic tools to set up and maintain a PLN with social media.
