Unfortunately, almost everything gets repeated numerous times, and as a whole the books ends up being thoroughly redundant. I read this book 20 years ago, just after my parents passed away.

The best part I like about this book is he gives a template on how to approach proofs. Explorar todas las posibilidades Comprobar que el resultado responde a la pregunta que nos hacen. How to Solve It: Kalsi — This revised and up-to date edition provides essential understanding of the working principles, operation. Prove that for all natural numbers n greater than or equal to 12, there is some combination of blue and red beads that is worth n credits. I remember I read the proofs in my calculus book in high school and had no idea of why the proofs were taking the steps they took. Home Groups Talk Zeitgeist.

And those were the kinds of things that we did. He used the book? JK — Yes, he used that book. What are we to find? Here is where you are trying to go. Whether it is a problem to find or a problem to prove, you are given something, [and] you want get somewhere. You actually can work both ways. Sometimes you can work backwards; sometimes you work forward. The whole idea, though, is to develop a connection to go from here to there.

HG — He mentioned that in your [] interview And he always asked that question. He would ask those general questions until we all understood this approach to problem solving: Lay out a plan, carry out the plan … Always check, checking over after you have a solution.

All of the things he had written in How to Solve It he would bring out in his lectures. JK — Yes, yes.

You see, Schoenfeld was much more interested, much more oriented to cognitive psychology, and I think that Schoenfeld thought that you needed to turn these heuristics into more teachable kinds of things.

There are a lot of ways to think of a simpler problem. I find that so, so… helpful, you know. I not only saw him teach number theory, I also saw him teach the so-called freshmen seminars, which were courses for small groups of freshman.

And that was very interesting to me, too. That was later in my career at Stanford. The seminars were in the evening, and it was too dark to walk back. So I would give him a ride back to his home. And so he gave [me] a wonderful opportunity. But still, after every lesson, he would replay the lesson taught through with me: Tell me what he thought had gone well; tell me what he thought it not gone so very well; talk about how he would do it differently if he was going to teach it again.

And that is part of why he did it, you know, it was a conversation that he and I had. But I thought it was really interesting. These are four dimensions in his teaching… JK — And another dimension — which I did not see, but I could tell was the case — [was] that I am sure that he prepared his lessons, his lectures, very carefully.

He had everything in his mind. He had worked out all of the problems. He knew how he wanted to present it. So he was prepared. I saw the rewinding, but I never saw the preparation. Except that I was in the class, and I could tell that he had thought about all of these problems and the questions that would come up.

One of the interesting things would be to watch him lay out things on the board. By the end of the lesson, everything is on the board. An American teacher just goes and erases and puts something [else]. So he never erased things that you were still looking at. He had it organized. Well, sometimes he would have to erase, of course. But before he erased, he would always ask if everybody … if it was okay to erase. But he was always very careful about laying out [the mathematics] on the board in such a way that you could see the development of the ideas.

Not many teachers in the U. What do you think about this? JK — No, they are not meant to be sequential. I think that is a distortion of what he said. And the way he used those phases, he would talk about how we would go from one phase another but not necessarily in that sequence.

You might start carrying out your plan and decide that you have to go back HG — To understanding. And he never treated those as a sequence that you march through. It is natural [to treat it as sequential]. He had to put it in some order in order to put it in the book.

But he is very careful. They are phases, and in any phase you can go in and out of one phase, you [can] go back from one phase to another. They were never meant to be sequential. JK — I think that this is probably true. Other people worked with issues on problem posing.

I think what he did do a lot was to talk about how by taking one problem you could transform it into another problem, or how you could create a problem that was a generalization, or a special case or—. So, generating one problem from another, he did all the time. But just generating a problem out of nowhere, he did not … he did not do that.

I find that looking back—. First of all, I found when I was teaching that looking back was the hardest thing to get children to do. It is too difficult to look back. He had … he had many things to say about looking back because he was concerned that you should learn something from having solved this [complicated problem].

You spent a lot of time on solving this problem. You should learn something from that. Could I … could I change this idea a little bit and get a slightly different problem and solve that? JK — Well, I mentioned the freshmen seminars; I mentioned taking the number theory course. We would go outside, and we would sit in the Stanford … Greek theater, actually. It is a kind of Greek theater, [an] open theater. And we would get into groups of four, usually four people. And he would give us problems of different types.

Usually each person got a different kind of problem. It might be [that] one problem was number theory, and another problem was geometry, whatever. And then we were to take turns teaching the problem to the other three people in the group. But you might have to give some careful hints.

If people were struggling with the problem, you gave some hints to solve it. And, and … but the group then would work on the problem, and after they finished one problem then they would move to the others. So, it was an exercise, it was an activity in teaching three other people to solve a problem, how to do it. And to see how they came up [with a solution] because sometimes they would get a solution that was different from the one that you did your way.

JK — What was he doing? Well, he was mostly just watching. We were sitting in groups around the Greek theater, and at that point he was just observing us. He was just observing us. I think that this came from his own experience in Switzerland when he taught there in Zurich.

And they would do some teacher education, and this was partly … his way of training teachers to present problems to other people. Inside questions.

It is an art because if you ask the wrong question or if you give the wrong hint, then there is nothing left to do. So you have to think very carefully how you… how you make a suggestion. I was thinking more about the kinds of problems that were in our textbooks, the textbooks of my students were using, which were mostly very routine word problems, and I was interested in how they learned to solve those problems, in trying to help them solve those problems, but I really had a very narrow view of what problems were, even though I had seen more interesting problems when I took the examination in school, more interesting problems were in the Stanford mathematics exam.

The word problems in the text books that I was teaching from were… simply opportunities to practice… writing an equation and solving an equation, they were very straightforward algebra word problems […].

Good book by Polya, he explains the process used in solving and proving problems. It is written in a somewhat awkward style, to an audience that is difficult to discern, and with enough repetition that I had to skip pages at a time to get to the next topic.
