We present ERM-Tutor, a constraint-based tutor that teaches logical database design (i.e. mapping conceptual to logical database schemas). Students practice this procedural task in ERM-Tutor by solving each step and receiving feedback on their solutions. We also present a new feature added to the system, which enables students to ask free-form questions. A preliminary evaluation carried out on ERM-Tutor investigated how students use free-form questions, and provided promising results. We plan to perform a bigger study in early 2006.
