The old-school model of a sage on the stage handing out facts to students and expecting those students to recite them back is not enough to prepare students to survive after high school. Today's educational community is tasked with teaching students to solve highly complex problems that require reading, writing, and math in addition to 21st century skills such as teamwork, time management, information gathering, data analysis, and effective use of high tech tools. The PBL model provides the framework for learning these skills, and requires teachers to guide and mentor students as they become directors and managers of their learning to enable them to compete in a knowledge-based, highly technological society.
