an IBL preface

In just over a week, I will distribute to students the first piece of the complex variables notes I have been writing. Here is a preface to be included with the notes, to motivate the IBL structure. The details of the class will be spelled out in the syllabus; this is just to set the tone.

You are the creators. These notes are a guide.

The notes will not show you how to solve all the problems that are presented, but they should enable you to find solutions, on your own and working together. They will also provide historical and cultural background about the context in which some of these ideas were conceived and developed. You will see that the material you are about to study did not come together fully formed at a single moment in history. It was composed gradually over the course of centuries, with various mathematicians building on the work of others, improving the subject while increasing its breadth and depth.

Mathematics is essentially a human endeavor. Whatever you may believe about the true nature of mathematics—does it exist eternally in a transcendent Platonic realm, or is it contingent upon our shared human consciousness? is math “invented” or “discovered”?—our experience of mathematics is temporal, personal, and communal. Like music, mathematics that is encountered only on as symbols on a page remains inert. Like music, mathematics must be created in the moment, and it takes time and practice to master each piece. The creation of mathematics takes place in writing, in conversations, in explanations, and most profoundly in the mental construction of its edifices on the basis of reason and observation.

To continue the musical analogy, you might think of these notes like a performer’s score. Much is included to direct you towards particular ideas, but much is missing that can only be supplied by you: participation in the creative process that will make those ideas come alive. Moreover, the success of the class will depend on the pursuit of both individual excellence and collective achievement. Like a musician in an orchestra, you should bring your best work and be prepared to blend it with others’ contributions.

In any act of creation, there must be room for experimentation, and thus allowance for mistakes, even failure. A key goal of our community is that we support each other—sharpening each other’s thinking but also bolstering each other's confidence—so that we can make failure a productive experience. Mistakes are inevitable, and they should not be an obstacle to further progress. It’s normal to struggle and be confused as you work through new material. Accepting that means you can keep working even while feeling stuck, until you overcome and reach even greater accomplishments.

These notes are a guide. You are the creators.

Josh, I'd love to borrow this (or potentially a modified version) for my syllabi and/or IBL notes for both intro to proof and abstract algebra. Would you mind? Of course, I'd give you credit.

Dana: I'd be honored! I've been looking over your materials for those classes to get a sense of what messages you try to convey at the start of an IBL class, so I'm happy if you find this expression useful. (I plan to include your declaration of "Rights of the Learner" in my syllabus, likewise with credit.)

Hi Josh,
I loved your article. If you are fine can I would love share your article in my class I am currently teaching. I make sure I will give you the credit.
Let me know.
