Introductory organic chemistry students can fail to fully grasp concepts taught in the lecture and their implications in the organic laboratory.  This leads to students being frustrated when performing an experiment containing unknowns, especially when they are unable to determine the structure of their product.  The mixed aldol condensation experiment described by Hathaway (J. Chem. Educ. 1987  , 64, 367-368) utilizes different unknown aldehydes and ketones to provide highly conjugated products.  In an effort to facilitate a more inquiry-based laboratory approach at Fordham University, I have developed a two step learning process for the mixed aldol condensation experiment that encourages students to have a more proactive view of learning.  Through the use of chemical drawing programs, melting points, 1H and 13C NMR spectral data, and a post-laboratory worksheet, an increase in students' understanding of the general reaction has been noted.  Representative data and student assessment also will be presented.
