My lectures are designed to supplement learning that my students are expected to have done prior to class. The lectures are a summary of the material, with worked examples, a chance to ask questions to clear up misunderstandings, and for discussion of key concepts.<p>Lectures are attended by dozens of students, so they cannot be a personalized tutorial service. That&#x27;s what office hours are for. My best students don&#x27;t usually need office hours as they are pretty much self-taught, but the next tier down show up regularly and we sit down together and go through exactly the material they want to focus on in the detail they need.<p>I tailor my pedagogy to these engaged students, not to the ones who expect to be handed an A for a minimum amount of effort. If you don&#x27;t work, you&#x27;ll deservedly do very poorly, and I&#x27;m not willing to waste my limited resources on you. And, no, I&#x27;m not going to curve your grade up either, because that&#x27;s not fair on the good students.<p>Unsurprisingly, poor students don&#x27;t show up to office hours, don&#x27;t take advantage of our free tutoring service, turn in material late, and regularly miss lectures. All these failings are entirely their own responsibility, not mine.
