    Описание: Математическое мышление – это не то же самое, что занятие математикой – по крайней мере не в том виде, как она представлена в нашей школьной системе. Школьная математика обычно заключается в заучивании последовательностей действий, решающих очень однотипные задачи. Профессиональные математики думают определенным образом, позволяющим справляться с действительными проблемами из нашей повседневности, науки и самой математики. Ключом к успеху в школьной математике является шаблонный образ мыслей. В противовес ему, ключевой особенностью математического мышления является нестандартный образ мыслей – крайне ценная способность для современного мира. Этот курс помогает развить именно такой тип мышления.

    NOTE: Coursera encountered difficulties in converting my course to run on the new platform. Working together, we have found a way to modify the course to circumvent the missing platform features, without losing too much of what made the course work. Completing that work will involve considerable time and effort, and I am unlikely to have much time to look at this until the summer. This means that the earliest Session 8 could run is Fall 2016. Please check back here in August. Sorry about this. – – Keith Devlin, 1/25/2016 (modified 4.21.2016)

    The goal of the course is to help you develop a valuable mental ability – a powerful way of thinking that our ancestors have developed over three thousand years.

    Mathematical thinking is not the same as doing mathematics – at least not as mathematics is typically presented in our school system. School math typically focuses on learning procedures to solve highly stereotyped problems. Professional mathematicians think a certain way to solve real problems, problems that can arise from the everyday world, or from science, or from within mathematics itself. The key to success in school math is to learn to think inside-the-box. In contrast, a key feature of mathematical thinking is thinking outside-the-box – a valuable ability in today’s world. This course helps to develop that crucial way of thinking.

    The course is offered in two versions. The eight-week-long Basic Course is designed for people who want to develop or improve mathematics-based, analytic thinking for professional or general life purposes. The ten-week-long Extended Course is aimed primarily at first-year students at college or university who are thinking of majoring in mathematics or a mathematically-dependent subject, or high school seniors who have such a college career in mind. The final two weeks are more intensive and require more mathematical background than the Basic Course. There is no need to make a formal election between the two. Simply skip or drop out of the final two weeks if you decide you want to complete only the Basic Course.
