Whether you're teaching children or adults, teaching English to Koreans can be a challenging task; however, it doesn't have to be daunting. Be patient as you teach, since most children won't understand the language right away. English, for some, is a complex language to learn. Be confident that over time, your Korean students will be able to speak English fluently with little to no mistakes.

Review the lessons you plan to teach before class begins. If you're prepared for class, your lessons will run smoothly, and you won't waste time sifting through your notes.

Offer examples of the words you are teaching. Bring in props such as an apple, a ball or a hat when you are teaching the respective vocabulary words. Then use those words in simple sentences, and ask your students to repeat them.

Ask your Korean students if they understood the material before moving to the next lesson. Encourage them to ask questions. After all, they won't be able to learn the language if something confuses them and isn't clarified.

Prepare games and fun activities. Don't just have the class all about lectures and note taking. Make it fun as well! Simple group projects, even if it's just doing a worksheet with another classmate, can make learning the English language more enjoyable. If your students enjoy themselves, they might be able to learn English with more ease.

Praise and encourage your Korean students. Learning any foreign language can be difficult. Some people find that learning English as a second language is especially challenging. The last thing that you want is for your students to give up. So, reward them every once in a while.

Converse in English with your Korean students. If your students hear the context in which a word is used, and if you make gestures while you're conversing with them, they will be able to better understand the meaning of each word. It may also be helpful if you bring a children's book written in English to class and read it aloud to your students.

Have your students keep an English diary. When in class, allow them to read their diary entries. You can also collect the diaries and correct their spelling and grammar.
