3 . While regular schools still exist, the virtual classroom plays an important role in today's learning community. Job opportunities for students are expanding rapidly and more people of all ages are becoming aware of online learning that allows them to study at home.
Be open-minded about sharing life, work, and learning experiences as part of online learning.
Many different people find that the online method requires them to use their experiences and that online learning offers them a place to communicate with each other. This forum for communication removes the visual barriers that stop some students from expressing themselves. In addition, students are given time to reflect on the information before replying.
Be willing to 'speak up' if problems arise.
Online learning is normally sequential（序列的） and requires commitment on the students' part. Keeping up with the face-to-face class and completing all work on time is vital. Once students get behind, it is almost impossible to catch up. Students need to want to be there and need to want the experience. The instructor may have to communicate with students personally to offer help and remind them of the need to keep up.
Just as many excellent instructors may not be effective online facilitators（诱导者）, not all students have the necessary qualities to perform well online.
| A．Keep up with the progress of the course. |
| B．Online students, however, require unique qualities to be successful. |
| C．Accept critical thinking and decision making as part of online learning. |
| D．Remember that instructors cannot see their students in an online course. |
| E．In this way, students can help to keep the online environment open and friendly. |
| F．Online courses require students to make decisions based on facts as well as experience. |
| G．But those who have the qualities discussed above usually make very successful online students. |
