Problem: Article: . Make a happy face in the direction of your teacher. It will help make you seem friendlier and more interested in what the teacher is saying. People respond well to smiles and other pleasant expressions. This is a simple tool, but it can be crucial to maintaining a good relationship. Just be careful not to spend too much time smiling at the teacher. You also should be looking at the board or taking notes. Otherwise, it looks like you aren’t paying attention. Most teachers can tell from the front of the room who is interested and paying attention. Teachers put a lot of effort into creating a class, and they like the reward of seeing people respond to it.  The best way to look interested is to keep your eyes forward, and take notes or write down things your teacher says. If you are looking somewhere else, or just staring without writing things down, your teacher won’t believe you are interested. As an added bonus, you will probably paying attention to the class. This not only means you will do better, but you will also be more likely to find out things your teacher likes. Teachers like it when students are involved and participate in class. If your teacher asks the class a question, be the first one to raise your hand. In most cases, it won’t matter if you’re wrong, as your teachers will appreciate the effort.  Wait for your teacher to finish asking the question before raising your hand. That will prove you are listening to the question, and will be ready to give a good effort. Just be sure you are trying to give a serious answer, and not making a joke. Teachers don’t like that at all. Like many other people, teachers have an unconscious bias towards people that look and act like them. If your teacher can believe you are like her in many ways, she will think better of you, and might be more lenient in grades. This is less true for a subject like math, where this is a right answer, but if you need to show your work the teacher might be more willing to give partial credit.  This doesn’t have to be related to the stuff you are learning about in class. If your teacher says she likes something, like a type of music or food, then tell her that you like it too. Adding something quick like “I love that song” or “Chinese food is my favorite” during class in response to her mentioning something is good enough. Just be careful not to tell your teacher that you like what she likes every time she mentions something. It will make your sucking up obvious, which won’t help. You can also mention it to your teacher after class, and maybe ask for more information. For example, if your teacher likes a certain type of food, ask what her favorite restaurant is, and tell her that you’d like to try it with your parents. Another way to mimic the teacher is to copy the way she dresses. Look at the particular way your teacher dresses, or if she likes to wear a certain color. If there is something you can copy, wear it when you can. You won’t have to say anything, as the teacher will probably notice the similarity subconsciously. If the teacher needs something done, be the one to do it. Your teacher will notice and appreciate that you want to make her life easier.  Your help doesn’t need to be big. It could be helping to set up for a project, or running a book to the library. Of course, if your teacher asks you to do something directly, do it with a smile and without complaining. Watch your teacher as well, and wait for moments when she might need help. If it seems like she is having trouble doing things in the class, or could use an extra pair of hands, ask if you can help. Even if she doesn’t need it, she will appreciate that you were willing to offer. If your teacher is having a debate in class, either as part of the lesson or because another student disagrees with him, figure out what he believes and repeat that argument. If the teacher is arguing with another student, and not as part of the lesson, don’t jump in during class. Instead, wait until afterward and tell the teacher you agreed with him. Or, if the teacher was dealing with a disruptive student, thank him for stopping it. Something simple like “Thank you for making Billy be quiet, I was having trouble concentrating” will be enough. Teachers like to feel appreciated, and believe they are doing the right thing.
Summary: Smile Look interested. Raise your hand often. Mimic your teacher. Volunteer to help your teacher. Agree with your teacher.
