You will get a number of web sites of English-speaking flag production companies with information on their products. Print these out and use them in your class. Write an E-Mail to the company and ask them to send you a catalog. Ask them what else is available on the Internet regarding flag production. Also, send an E-Mail to the 13,000 teachers in the English teachers news group and ask if anyone has experience teaching English at companies involved in flag production.
Digitalization removes geographical barriers and saves time.
Digitized English teaching removes the geographical barrier which frees up time for both the teacher and the students. Digitalization brings like minds together. Back in the 17th century, Leibniz and Newton developed Calculus independently of one another. If they had lived today, they would have met by now in a newsgroup and would already be exchanging ideas via E-Mail. The ease which the Internet provides to meet people with similar interests, professions, backgrounds, and experiences is unparalleled in human history.
