...the source of all great mathematics is the special case, the concrete example. It is frequent in mathematics that every instance of a concept of seemingly generality is, in essence, the same as a small and concrete special case.
Paul HalmosRead
It is the duty of all teachers, and of teachers of mathematics in particular, to expose their students to problems much more than to facts.
Interpretation
Teachers should focus on presenting students with problems to solve rather than just facts to memorize.
In this quote, Paul Halmos emphasizes the importance of engaging students with challenging problems in mathematics rather than solely delivering factual knowledge. This approach encourages critical thinking and deeper understanding, fostering a learning environment where students learn to apply concepts and develop problem-solving skills, which are vital for their growth and success in the subject and beyond.
In practice
In a seminar on innovative teaching methods, I would use this quote to explain the importance of problem-based learning.
...the source of all great mathematics is the special case, the concrete example. It is frequent in mathematics that every instance of a concept of seemingly generality is, in essence, the same as a small and concrete special case.
[Mathematics] is security. Certainty. Truth. Beauty. Insight. Structure. Architecture. I see mathematics, the part of human knowledge that I call mathematics, as one thing - one great, glorious thing. Whether it is differential topology, or functional analysis, or homological algebra, it is all one thing. ... They are intimately interconnected, they are all facets of the same thing. That interconnection, that architecture, is secure truth and is beauty. That's what mathematics is to me.
Our kids didn't do this to themselves. They don't decide the sugar content in soda or the advertising content of a television show. Kids don't choose what's served to them for lunch at school, and shouldn't be deciding what's served to them for dinner at home. And they don't decide whether there's time in the day or room in the budget to learn about healthy eating or to spend time playing outside.
Kids ask me questions. You'd think after doing this for four years, I would have heard every single question anyone could think of to ask, but no, every time, they surprise me, they ask me something I never thought of before.
I desire to assist in attracting to this profession young men of character and ability, also to help those already engaged in the profession to acquire the highest moral and intellectual training
All of these young people have some kind of potential in them. And if we don't invest in them as a nation, regardless of where they come from or what color they are, if we don't invest in them, we lose.
You cannot transmit wisdom and insight to another person. The seed is already there. A good teacher touches the seed, allowing it to wake up, to sprout, and to grow.
Every day in school, we said the pledge to the flag, 'with liberty and justice for all,' and I believed all that.
