A virtual classroom comes with a private link and password. In comparison, Skype is not secure and is even banned in some countries and companies.
In a virtual classroom, it is possible to engage all the learner’s skills at once – speaking, listening, reading and writing. The instructor works with a professional presentation of content, discussion boards, and different types of media (PowerPoint, MP3 audio, short videos, etc.) – With Skype, the content can tend to end up as mere conversation lessons.
In a Virtual Classroom, the instructor and students can see the same screens simultaneously, and each other. There are also chat windows for new vocabulary, expressions, spelling, comments, Q & A (in writing). Skype is fine for the individual, but it is not a professional training tool.
Each class is recorded and sent to the student in two formats (virtual class recording & MP3 audio). These are excellent tools for reviewing what was covered in each class. In small group classes – a student who misses a class can catch up on what they missed. With Skype, there is no recording.
