Groups •  Explicit  group  formaAon:   –  Google  Groups,  Yahoo  Groups  

•  Object-­‐based group  formaAon   –  Facebook  ‘causes’,  ‘like’,  etc.   –  Events  


Sharing •  Media  –  photo,  video  and  audio  uploads   •  Artwork  –  DeviantArt  -­‐   hFp://www.deviantart.com/   •  Experiences     –  the  TwiFer  hashtag  again  

•  Places –  4Square

Some Benefits   •  It’s  free   •  It  cuts  down  on  isolaAon   •  It  builds  tolerance  and  understanding  of   diversity   •  It  amplifies  passions   •  It’s  more  open,  and  educaAon  needs  to  be   more  open   George  Couros,  Connected  Principals,  Why  Social  Media  Can  and  Is   Changing  EducaAon   hFp://www.connectedprincipals.com/archives/3024

Social Network  Policies   •  Schools  banning  Facebook?   •  “Discussions  of  privacy  and  copyright,  and   quesAons  about  creaAvity  and  appropriaAon,   ciAzenship,  and  governance  can  become   grounded  in  years  of  social  media   experience.”  –  Alexander   Digizen,  Case  Study:  Example  Acceptable  Use  Policy   hFp://old.digizen.org/cyberbullying/fullguidance/resources/ caseexample.aspx

4. Pla>orms  and  Programs  


To Understand  Pla>orms…   •  Think  of  Mobile  compuAng:   –  iPod,  iPhone,  iPad   –  Android,  Windows  Mobile,  Blackberry  

•  Next, think  of  ‘the  App  store’   –  eg.,  the  Apple  app  store  

•  Apply the  concept  to  a  social  network   –  inside  the  social  network  is  an  ‘app  store’   –  these  apps  access  SN  data  and  funcAonality  


Some Analogies   •  Extensions  in  Firefox  or  Thunderbird   •  Modules  in  Drupal  or  WordPress   •  Google  Apps  in  Chrome
