One experience is worth thousand warnings – learning from experience

A university professor once gave an assignment to his students at a major university in the United States in which the students had to write an essay addressing the following question: “What is risk?” One of the students responded with just one sentence and his name on a blank piece of paper: “This is risk!!!” The professor was dazzled and gave an A+ to this three word essay.

Next year, the same professor gave the same assignment to a different group of students. One of the students, familiar with what happened the last year, submitted a similar essay which received an F along with the following comment made by the professor: “It is foolish to take the same risk twice.”

Learning from experience is an important issue for everyone. No matter how many times you tell a child not to approach a hot stove, he will learn this only after he gets burned once; a Turkish proverb goes as follows: “One experience is worth a thousand warnings.”

In fact, learning from experience is absolutely essential sometimes, especially while we are teaching mathematics. Every so often, we want our students to make some very critical mistakes and we create questions with a variety of traps that our students will very likely fall into. The reason is simple. When our students make such mistakes, we will have the opportunity to bombard them with a heavy load of knowledge.

Experience does not only involve learning from mistakes; it also comprises learning from experimenting. At this point you might start arguing that mathematics is not an experimental branch of science. With all due respect, this is not true. We can conduct experiments and we are very fortunate that our experiments only require a pen, a few papers, and our brains.
