Lifelong learning is an emphasized graduate outcome for engineering professionals at the international level by the Washington Accord and at the United States national level by ABET. When a new engineer enters the profession, she will be expected to acquire new technical knowledge in order to solve a problem or create a design. Unlike her experience in college, there will not be a professor to guide this learning. The planning, execution, monitoring, and control of this learning will now fall to the new engineer. The level of the ability to succeed in this self-directed learning modality will be a function of the extent to which the lifelong learning outcome has been met. This paper studies the importance of this graduate outcome and the development of self-directed learning as the way in which the outcome is achieved. Quantitative measures are taken using the Self-Directed Learning Readiness Scale. Quantitative results show a statistically significant difference between the developments of self-regulated abilities by students in a two-year PBL curriculum as compared to students who did not undergo the PBL treatment
