... Let me start with the top mistakes that teachers make. Some of these mistakes are forced on teachers by a badly designed education system, and some are ones that teachers make no matter what they are teaching or which system they are teaching in. Some of these are less than obvious, so let's consider them one-by-one.1. Assuming that there is some kind of learning, other than learning by doing.2. Believing that a teacher's job is assessment.3. Thinking there is something that everyone must know in order to proceed.4. Thinking that students are not worried about the purpose of what they are being taught.5. Thinking that studying can replace repeated practice as a key learning technique.6. Thinking that because students have chosen to take your course, they have an interest in learning what you plan to teach them.7. Correcting a student who is doing something wrong by telling them what to do instead.8. Thinking that a student remembers what you just taught him.
