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.
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,
- remain focused, and
- bring instinct and intuition to bear when needed.
