The best version I've seen for image-heavy lectures is the lecturer writing with his pad on half-prepared slides, which have also been given to the students for print-out. It combines the advantages from pure slides with pure blackboard writing: - The student has enough time to think and not just write (has often been a problem when the professor is writing very fast and doing complicated stuff). - The student still gets to 'touch' the material and have their own take on it, and writes the critical points and diagrams themselves. - There is no fear of missing something in the hand-written notes when as when deciding between writing and thinking/try to figure out which parts to note down.
