Beginning in the early grades , students use their knowledge of economics to improve basic skills and their performance in other subjects . In addition , students use their speaking skills in the TL to present their MOO discoveries to the class . Passing by tables under a large tent in the quad 's southeastern corner , students used their meal plans ( others paid $ 7 ) and loaded up their plates with a variety of submarine sandwiches , cookies , brownies , pretzels and other snacks , milk , juice and piles of fresh fruit . As part of this year 's field work component , students used their botanical expertise to assist with an Australian National University research project at Jervis Bay looking at animals such as bandicoots and the rare Eastern Bristlebird . For example , after an initial library instruction day , students used their laptops to access the DePauw Library website to find appropriate sources for a group project .
