Project Based Learning (PBL) is a concept/method that can promote active learning if done properly. 

Project Based Learning encourages students to solve real world problems and/or complex problems over the duration of long-term projects. 

An example of PBL in practice is a collaborative project conducted at my current school by the Math + Science departments to re-design the city of Tegucigalpa, Honduras to decrease traffic. 

Below is a link to a website that helps define PBL from PBL works:

PBL helps promote knowledge producers rather than knowledge consumers while promoting authentic assessment.  

Below is a video from PBL works that defines the concept in video format.
