I recently finished my Bachelor's thesis in math and I am about to be having my bachelor thesis defense (colloquium). The topic I've covered in my thesis is highly theoretical (differential- and algebraic topology) but also quite geometrical, i.e. I've added quite a lot of illustrations into my thesis.
I am now preparing my bachelor thesis defense where I am going present the work I've done and answer questions from my supervisor and maybe some other professors.
However, I am quite uncertain whether to do it the traditional way, i.e. writing myself a short lecture-script and writing the things I am presenting on the blackboard using only chalk.
Or rather setting up a "fancy" LaTeX-Powerpoint presentation where everything might be already written down and illustrated and I am basically just explaining what is going on.
The obvious advantage of using a Powerpoint presentation is that I might save a lot of time I would otherwise spend on writing everything down on the blackboard such as definitions, theorems etc.
On the other hand, I actually like the traditional style where I can draw the pictures on the blackboard and write things down my own (similar to a lecture). I am also always a bit sceptical about Powerpoint presentations (in mathematical lectures) since it forces me to read things out rather than write things down.
What would you recommend? This might indeed be a question I could ask my supervisor, but he will most likely be open to both and I think this is more a question about "personal preference" where both directions might be appropriate.
