The best version I&#x27;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.<p>It combines the advantages from pure slides with pure blackboard writing:<p>- 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).<p>- The student still gets to &#x27;touch&#x27; the material and have their own take on it, and writes the critical points and diagrams themselves.<p>- There is no fear of missing something in the hand-written notes when as when deciding between writing and thinking&#x2F;try to figure out which parts to note down.
