Schedule lectures for your students at specific times of the day. Make sure you understand the time difference, if you live in America while teaching. Time differences can vary from 10 to 12 hours, depending on where you live.
Write lessons plans that focus on teaching English in various ways, including spelling and pronunciation. Make sure you have a basic grasp of the Korean alphabet or a translation guide before writing your lesson plans.
Email your lessons plans to your students. Communicate lecture schedules to your students and other important information, such as changes of schedule, homework changes and test days.
Hook up your web cam and microphone and check to make sure they work. Record a simple message for your students and post it on your website to greet them to your class.
Record your lectures and post these to the website of the institute for which you work at your scheduled time. Use these recorded messages to help model English pronunciation to your students.
Set up daily "instant message chat sessions" using a free chat service, such as MSN or Yahoo. Use any service that your students all feel comfortable using, including services your institute may have set up for chatting.
Answer any questions your students may have about the lesson during your chat sessions. Use voice and web cam support, if possible, especially with pronunciation questions.
Check your email several times a day to take questions from your students that may not have been raised during your chat sessions. Answer these questions, using written and video messages, if possible.
