The lecturers should also explain the connection of what they teach and the real life. This is because to ease the students to get the picture of what they learn and also give them benefits in the real life. Moreover, it is OK to make jokes and I also advise to make some jokes but it must be a matured jokes. How? Well, this is very subjective, I do not know how to explain in writing. But, basically what I can tell, other people laugh because of your jokes while you don't.
Besides that, the lecturer should respect the time. When, the class is at 9.00 am for example, they must understand that some students are just coming from other class, they might need a little rest or they might need a time to get prepare with books and stationaries and etc. So, it is advisable to start at 9.05 am or 9.10am. However, this depends on the situation. If the students are already ready before the class starts, then it should be OK to start on time.
One more thing that the lecturers oversee is the time to finish the class. Some might think that if the lecturer is using additional time to finish his lecture, he or she is a good and hardworking lecturer. For me, they are not what as expected. They should manage the time well, plan the syllabus that have to be finished and respect other people's time. Some of the students might have other class or maybe need a time to rest or others. If the class finishes at 10.00am, then 10.00am the students should start going out from the class.
Well, to say it again, this is just my opinion. Whether it works or not, it depends on yourself. Wallaua'lam...
