Most of us can learn how to do something simple on our own with just a set of instructions. However, to learn about something more complex, it's always best to have a teacher.

Teachers bring with them varied and useful backgrounds. They've been trained to teach individuals in different ways depending on their style. For instance, omen students learn better by discussing a topic. Others learn more by writing about it. Teachers can help students learn in the way that's best of each student. A textbook or a manual can only give you one way of learning something. Plus they're only as helpful as your ability to understand them. A good teacher can adapt her teaching to your needs.

Teachers help you focus on what you're learning. If you're learning something by yourself, it's easy to become distracted, and go on to other activities. Teachers keep your attention on the subject. They also approach a subject logically, taking it one step at a time. On your own, it's tempting to skip parts of the learning process you think you don't need. That can binder your ability to really understand the subject.

Learning a subject on your own is a very narrow way of learning. You can only use the information you get from the textbook. With a teacher, you get the information in the written materials as well as the teacher's own knowledge of the topic. Teachers can also provide extra materials to broaden the scope of what you're learning.

There's nothing wrong with studying on your own, and a learner can always benefit from some quiet study. For the best possible learning, though, a good teacher is the biggest help you can have.
