I don’t claim that this material is easy. But after all these weeks, why are there still so many people who just can’t get the homework right? (And don’t even get me started on the people who refuse to do the homework.) We do the homework at — you guessed it — home. Sometimes I do it in my car (parked outside Starbuck’s). The book is right there. We can look everything up, so memory failure is not an excuse. While the explanations in the book are not excellent, they are adequate for use with the rather lame exercises. And yet, when we go over the homework in class, person after person gets it wrong. If there are four ways to get it wrong, four people in a row will get it wrong. Some will even repeat the wrong answers already given. Certainly, getting an occasional wrong answer is no crime. Everyone does it. But what I see here is a huge lack of understanding. Many students just seem to be randomly guessing at the answers. They don’t understand what makes one answer right and another wrong, so they cannot learn from their mistakes, but are forced to guess randomly again the next time. It is a tedious process. I am so glad I am not a teacher.
