Mathematical maturity is an informal term used by mathematicians to refer to a mixture of mathematical experience and insight that cannot be directly taught. Instead, it comes from repeated exposure to mathematical concepts. It is a gauge of mathematics student's erudition in mathematical structures and methods. The topic is occasionally also addressed in literature in its own right.
Mathematical maturity has been defined in several different ways by various authors.
One definition has been given as follows:
... fearlessness in the face of symbols: the ability to read and understand notation, to introduce clear and useful notation when appropriate (and not otherwise!), and a general facility of expression in the terse—but crisp and exact—language that mathematicians use to communicate ideas.
A broader list of characteristics of mathematical maturity has been given as follows:
the capacity to generalize from a specific example to broad concept
the capacity to handle increasingly abstract ideas
the ability to communicate mathematically by learning standard notation and acceptable style
a significant shift from learning by memorization to learning through understanding
the capacity to separate the key ideas from the less significant
the ability to link a geometrical representation with an analytic representation
the ability to translate verbal problems into mathematical problems
the ability to recognize a valid proof and detect 'sloppy' thinking
the ability to recognize mathematical patterns
the ability to move back and forth between the geometrical (graph) and the analytical (equation)
improving mathematical intuition by abandoning naive assumptions and developing a more critical attitude
Finally, mathematical maturity has also been defined as an ability to do the following:
make and use connections with other problems and other disciplines
fill in missing details
spot, correct and learn from mistakes
winnow the chaff from the wheat, get to the crux, identify intent
recognize and appreciate elegance
think abstractly
read, write and critique formal proofs
draw a line between what you know and what you don’t know
recognize patterns, themes, currents and eddies
apply what you know in creative ways
approximate appropriately
teach yourself
generalize
remain focused
bring instinct and intuition to bear when needed
