I currently have Zoltan for MATH2001 in the 2nd half of the Summer Semester 2017-18(having Philip Isaac in the 1st half). The transition has not been easy as the custom with all workbook based Maths subjects at UQ is the lecturer goes through the workbook in front of us making it easy for us to follow and copy down notes. Zoltan, however, uses a PowerPoint presentation every lecture leaving almost every student confused as to where to take notes in the workbook.
Additionally, attending lectures at UQ is a major hassle for me and as he doesn't speak into or anywhere near the microphone provided, I can barely hear him and I struggle to understand a majority of what he is saying through Lectopia. I have checked with at least 5 other students who attend lectures on this and they have all said he has made the learning aspect of the course much harder than it needs to be in terms of lecturer coherence. I've resorted to downloading past lectures and listening to them as they use the workbook and are actually audible.
