Hello Jane, Another way of saying the previous: " The major element to enable a student to develop his megacognitive skills becoming conscious of his own thinking lies in understanding the fact, that possessing the qualities to learn isn't part of a personal nature, a matter of fact acquired at birth, rather a skill acquired over time by training and persistence.

not paraphrase but I hope it helps: One's ability to learn is a skill that develops over time. It's not a fixed trait that inherited at birth. Understanding above is the key to a student's ability to become a self-regulated learner.

My try: The ability to learn is a skill that develops over time than a fixed trait or inherited at birth. This factor is a key in understanding that student himself/herself is able to become self-regulated learner.
