To assist students in their problem solving process, Alien Rescue provides a variety of new media enriched cognitive tools, including a database of information on our solar system, a database on the alien characteristics, a database on probe missions carried out by NASA, a probe design tool, mission status tool, a notebook, notebook comparison tool, visual tutorials on various scientific concepts. With all these cognitive tools at their fingertips, students can concentrate on solving the problem and teachers can make best use of their time to facilitate the learning process. The roles of students and teachers are therefore shifted. Students become active seekers of knowledge, while the teacher becomes the "guide on the side," helping students find the information and learn the skills they need to solve the problem.

"How do you describe Alien Rescue to a friend?"
Liu, Horton, Olmanson, & Toprac (2011)
Alien Rescue is a great example of problem-based learning. Our test and quiz grades are higher than the years before when we did not use Alien Rescue.
