In my country, teachers often ask tricky questions or try to provide false information, so that the students have to pay attention in order to notice it and then proceed to build a compelling argument to prove the educator wrong. This type of exercise is very useful, that is why I used it as well and the results were also satisfactory. For example, in group discussions or during the question session of the oral presentation I oftentimes asked questions that required additional thinking and drawing on the students’ background knowledge, so that could provide an answer or even challenge me back.
As for the interaction between professor and the students, I believe it was also quite good. As I could tell from the PPT alone that the teacher spent a lot of time preparing it, with all of the graphic examples and readings. He also obviously knows quite a lot on various subjects and is willing to share the knowledge and help students grow. Professor is also very patient, as he gave plenty of time and space for students to think, if they were shy or unsure. Students were also at ease; many of them did not hesitate to share their mind with the class or discuss the topic of the lesson.
It was definitely an example of good learning environment.
