This article demonstrates an innovative method used to determine the need for information literacy among science undergraduate students at Adelphi University. Using clickers technology, this study measured the disconnect between biology undergraduates' perceived and actual knowledge of scientific literature. The quantitative data collected in the clickers sessions clearly show the deficiency of knowledge about the structures and contents of various types of articles published in scientific literature that exists in biology undergraduates. This study reinforces the importance of incorporating information literacy into training and learning processes for science majors. (Contains 10 tables.)
