Explain the problems you face when you listen a lecture?

Answer:
Our reliance on lectures is the most glaring example of the problems plaguing education. Lectures are so futile that I would feel foolish describing their inadequacies if they were not so pervasive. Everyone recognizes the basic lecture model: a teacher stands at the front of the room, while students sit quietly taking notes. At university there is no attempt to disguise this model. With enrollment for some classes in the hundreds, there is little chance to do much else. A walk through the halls of any high school will confirm that lecturing is the predominant model there as well.
The biggest problem with lectures is that they are inherently ineffective because they involve groups. Students bring to class different backgrounds, experiences, interests, and aptitudes. It is impossible to meet the optimal learning pace of all students because one teacher cannot deliver dozens of customized lessons simultaneously.
Teachers do their best by teaching to the “middle of the class”. But in trying to meet the needs of all students, they meet the needs of few. Slower students are left behind, while faster students are left twiddling their thumbs. The time of both groups is wasted. However, this is a simplistic analysis. Students are not so neatly sorted into slow learners and fast learners. In reality, each student finds certain topics easier, relative to the rest of the class. There are three layers of student differences: general student ability, specific topic ability, and the minute-to-minute variations in a student’s focus. Together, these make it impossible for lectures to meet the optimal learning pace of all students at all times.
