Einstein has famously said, "The important thing is not to stop questioning. Curiosity has its own reason for existing." Curiosity fuels the desire to seek answers which is the guiding principle behind all learning, discovery and invention in human landscape. Curiosity holds the learner’s interest and makes learning enjoyable and effective. So, students must never be discouraged from questioning. At the same time, they should be encouraged to find answers themselves, rather than to continue questioning with the expectation of receiving readymade answers from the teacher.
