The purpose of this study was to determine transfer of learning from an introductory to an advanced course in biology. All lecture sections in the advanced course at New York City Technical College were used for random sampling in the study. These lecture sections consisted of a mixture of students who were exposed to techniques of transfer of learning through the introductory course and those who were not exposed to the techniques of transfer of learning, but directly entered the advanced course. The findings of the study indicated that there was a significant difference between the mean cumulative lecture grade of students exposed to transfer of learning and the mean cumulative lecture grade of students not exposed to transfer of learning. As a result of the study it was recommended that the introductory course be mandated as a pre-requisite for the advanced course, and that further studies be conducted for an extended period of time prior to such a decision. It was further recommended that other introductory courses be redesigned and evaluated for positive transfer of learning to advanced courses in the Department of Biological Sciences and college-wide.
