21 Century Learning Design
The 21CLD resources are a set of resources that can be used by teachers to identify improvements to lesson and unit plans to improve engagement through the use of 21st Century skills. These resources have been developed by Microsoft, as an extension of the 4Cs.
There are 6 dimensions that the 21CLD addresses in unit plans. They are
 Collaboration
 Knowledge Construction
 Self Regulation
 Real World Problem Solving & Innovation
 The Use of ICT for Learning
 Skilled Communication
For each of these dimensions, the 21CLD resources provides clear definitions, and a flow chart that allows teachers to identify how well their plan implements that dimension, and to improve implementation of that dimension.
Example: Collaboration
The definition for Collaboration is
Students work together when the activity requires them to work in pairs or groups to:
 discuss an issue
 solve a problem
 create a product
Each of these parts can then be evaluated within a unit plan using tables like the one below.
IS THIS WORKING TOGETHER? 

YES:  NO: 
Pairs of students give each other feedback  Students do their work alone 
A small group discusses issues together  A whole class discussion on an issue 
A student uses Skype to interview a student in another school or town.  
Students use OneNote to share their story drafts and give each other feedback  Each student creates his/her own story and sends it to the educator for feedback. 
Each dimension also includes a Rubric to measure the effectiveness of that dimension in a unit.
Collaboration: Rubric
In this learning activity,
 Students are NOT required to work together in pairs or groups.
 Students DO work together
 BUT they DO NOT have shared responsibility.
 Students DO have shared responsibility
 BUT they ARE NOT required to make substantive decisions together.
 Students DO have shared responsibility
 AND they DO make substantive decisions together about the content, process, or product of their work
 BUT their work is not interdependent.
 Students DO have shared responsibility
 AND they DO make substantive decisions together about the content, process, or product of their work
 AND their work is interdependent.
The Rubric also assists teachers in identifying how their unit can be improved in each particular dimension.
The resources are freely available for anyone to use.
