Some evaluation criteria and instructions for the lectures -If you can also explain why something happens, and not only what happens, it may have a positive influence on evaluation. -Consider how you are going to present your topic. You don’t have to use only slides but for example the board or some other methods -If you try to get some interaction between the audience and yourself (e.g. by making questions), do not hesitate to try it. -You can use all existing slides on the Noppa-page but it is allowed to make new ones, too. -You can also use some material of your own if you have it or you find it somewhere.

Some evaluation criteria and….. continues -Do not be afraid of mistakes or “black outs”. Teaching personnel will help you if necessary -I’ll send you some detailed instructions by what issues you should especially focus on in your lecture -Some topics may be slightly more challenging than the other ones. This will be taken into account in the assessment. -You will get a short verbal feedback after the lecture -Do not hesitate to contact teachers if you don’t understand something or you do not know how to proceed. So, prepare your presentation few days earlier than you have it. -Take this as a positive challenge
