I just came across this excellent resource shared by Jeff Dunn and wanted to share with you. This is basically a chart created by the folks in BEI and outlines some important terminology employed in project based learning.
As you know by now, project-based learning is an instructional approach that aims at improving learning through hands on activities. Students learn better when they collaborate together on projects. These projects are usually built upon authentic learning tasks that engage students' interest and motivation. " These activities are designed to answer a question or solve a problem and generally reflect the types of learning and work people do in the everyday world outside the classroom.”
