I teach a variety of undergraduate and postgraduate modules at the university in this semester. The modules include 'Basics of Databases Design and Evaluation in Social Sciences', 'Practical Computing', 'General References', and 'Statistics & Probability' for undergraduate students and 'Information Storage & Retrieval' and 'Basics of Computer Programming' for postgraduate students. At the first session of each module I asked my students to draw a simple mind map of their perceptions about what they already knew about the subject and what they expect to learn during this semester in the module. Most of them were somehow uncertain about what they might learn during the module. I'll ask them to draw another mind map at the end of the semester to compare these two which I hope would be considerably different.
