But this is not all. Interactive conversations can be digitized. Interactive environments, for instance, a classroom, a train station, or a business meeting can be digitized. Since English instruction consists primarily of text, pictures, voice, video, conversation, and interactive environments, English instruction can be almost fully digitized. English instruction is more efficient when teachers use a digitized medium.
Digitalization increases student-centeredness .
If a student writes a digitized document and gives it to you to correct, you can add notes to the document just as you can to a regular paper document. Connected to this is a grammar chat room with students and tutors who discuss and answer questions about grammar. The student learns what he needs to know when he needs to know it. Digitalization increases accessiblity. Particularly in English for Specific Purposes, and more particularly in non-English speaking countries, specific material in English is fairly hard to come by.
