A learning log is a written account of what we have done in class. As we will spend a lot of time working on problems on the whiteboard, your learning log will be the place where you summarize the ideas discussed in your groups and within the class as a whole.
Ideas should be written in your own words. There is a course book that has been prepared for you with detailed examples and information, but the intention of the learning log is not to copy what has been written in that book.
If you can put an idea from class into your own words, then you have really understood the material. If you can’t, you should be asking some questions so that you get help to understand the material before moving on to new ideas. A learning log is a chance for you to think about what you have learned in class and what questions you still have.
Developing your mathematical voice is a part of what is expected in a mathematics class. You are expected to communicate your mathematical thinking in many ways, and to use mathematical vocabulary and language to contribute to mathematical discussions.
Scientists "talk" to themselves as they work through problems as a way of clarifying their thinking. Your learning log is a way to create a conversation with yourself about the mathematics that is taking place in the class.
Most learning logs are written accounts of the concepts we are addressing each day. However, there are other ways to keep track of your thinking, and I am open to the possibility of a audio learning log in which you discuss the ideas rather than writing.
Professional mathematicians spend most of their time writing: communicating with colleagues, applying for grants, publishing papers, writing memos and syllabi . . . It is ironic, but true that most mathematicians spend more time writing than they spend doing math.
But most of all, one of the biggest reasons for writing in a math class is that writing helps you to learn mathematics better. By explaining a difficult concept to other people, you end up explaining it to yourself.
