In contrast to the determinist and non-discrete structure of classical physical concepts, the probabilistic and discrete/quantised structure of quantum physics embeds certain difficulties in deeper understanding and teaching activities. In this study, in order to understand and to teach the concept of quantization more effectively, a clear analogy has been set between the classical world, that is well-known modes on a rope and the quantum world, that is the quantization in the infinite square quantum well. The established analogy is exceptionally beneficial in order to internalise and teach the hard concept of quantization in a much better way.
