Teaching happens only when learning takes place. We can judge our own effectiveness or teaching ability from the ability of the students to grasp and learn. Present-day education aims at memory training and by-hearting. Children are just told to memorize without understanding the meaning or the concepts. Present-day education bypasses reflection. Reflection is required to see the usefulness and practical utility of the matter that you just heard or learned. It helps you to pause for a while to think about the matter and to introspect to see how it affects your life.
