CARE about your students.... all of them. Dont embarrass your students, ever. Try to get the ones that dont seem interested... interested. Pay attention to them as much as you would want them to pay attention to you.... and if they want to talk to you.... LISTEN
Teach by using fun. When i was in the 6th grade, i was put in a program called "Discovery." And what we did in it was we would learn things by going on field trips. We went rafting and climbing and hiking and we had so much fun. If you let your students have fun in class and learn at the same time, then your students would love to go to school.
Remember you are in charge. It is ok to joke with the students but be appropriate about it. Set ground rules as to when joking is fine and when work is the priority. Try to make lessons fun and relevant. Make them see how what they are learning will effect their life.
Get to know your students. Keep simple notes like attendance. If a student is consistently late maybe they need transportant schedules or rides. Look them in the eyes when you speak and call them by name. Listen to what they say and never talk down to them but comment back to them and try to relate it to class. Decorate your classroom and provide additional reading material on the subject. Have fun. I will never forget my college professor in computers playing the ukulele and singing definitions to us before an exam. Or the car wash fund raiser we had for our Washington dc trip in seventy grade. Rearrange your classroom so all the seats are in groups or bring in a snack if everyone turns in all their homework assignments. Speak clearly answers questions and be helpful in giving notes and teach the subject reading your assignments before hand and emphasizing the strong points. Use other students to help other students and remember everyone learns best with praise patience and persistence and positive attitude. Remember your manners as they are learning from you things you never meant to teach them.
