Well structured and comprehensible. Ms Georgina Cornwall makes pleasant pauses between sentences, speaks clearly and explains so that it is easy to follow. The questions afterwards are also very helpful.
I liked this lecture and I also like this teacher. I just sometimes find the explanations a little be confusing.
Hello, I love supporting women in science and education, etc. I also will share my honest opinion to improve the educational site. This lecturer, while alright, is not the best you could get for Lecturio students. Her constant glancing over her notes is distracting and she is not very well articulated. Even though she is Ph.D., she has not digested her lecturing materials to the master's level. It is very unfortunate that she lectures on one of the most important subjects within your platform. Why you chose her? For the sake of diversity and involvement? I am sure there are much better and knowledgeable lady lecturers. Did not you see the disengagement and flaw after a couple of her lectures? Was she so cheap?
