When teaching more than 14 students in the class it is nearly impossible to maintain eye contact with each and every student. When losing that eye contact it is nearly impossible to sens the students. Many of today students don’t feel comfortable asking basic questions and as a result of that, they are left behind. Teaching in big classes with more than 14 students makes it nearly impossible to take a look at the code each student write. When the class is relatively small the delivery of the training material feels more like a private lesson. Each and every student gets personal attention. When the class is less than 14 students we can use a comfortable premium meeting room instead of a simple classroom. The premium public professional courses we deliver in life michael are always limited to 14 participants (max).
