The document compares 20th century learning to 21st century learning. It discusses how information, authorship and creativity, participation, and citizenship have changed between the two centuries. Some key differences include:
- Information in the 20th century was contained in discrete sources that were difficult to access, while 21st century information is ubiquitous, searchable, and easy to edit and share.
- Authorship and creativity was typically individual work in the 20th century, whereas the 21st century enables highly collaborative work across different media and with global audiences.
- Participation was limited to in-person discussions in the 20th century, but digital tools now allow participation anywhere through various media like video and text.
