More and more universities around the world are offering opportunities for students to obtain degrees online from the comfort of their own homes, and many of these institutions are authorized, meaning that they have met certain standards of excellence.
    If you decide to take language courses online, or any subject for that matter, be sure to evaluate the benefits of studying online versus going abroad. The advantages of studying online are that the costs are usually lower, you can study at your own pace, and you have access to the materials 24-hours-a-day from almost any computer in the world.(31)However, you won’t get the human interaction of meeting people face to face like you would if you were physically attending a school overseas.
    On the other hand, the advantages of going overseas may include day-to-day opportunities to learn a new culture, meet new friends with whom you can use and practice the language, and chances to see different parts of the world.(32)However, there may be a number of disadvantages including expense, time away from one’s school, family, or work life, and the challenge of adapting to a new culture and way of life.
    Whatever you do, consider a distance education program that meets your educational needs, is within your budget, and equally important, provides you with opportunities to grow beyond the classroom through cultural and educational activities.
