Hello shanshan,

Thanks for sharing your experience. I agreed that repetition strenghthens memory and imperceptibly influences learners. When learners becoming proficient with skills or the knowledge they learned, their behavior will become habitual.

Hello Elben,

Thanks for your post! I like these examples you stated, learning process must follow the principle of gradual improvement and at first scarcely visible. We may forget when was the first time using multiplication operators but it etched deeply in our memory so that we can have access to the knowledge at anytime.
