Ok. Well, let's say we start answering some of these wonderful questions? Here's my $0.02.
1. How do you think school will be like in the future?
=> I think there will be a demand for more non-native English teachers and less of a demand for native English teachers. The reason being, the latter are cost effective, not to mention they are able to function more effectively in a bilingual classroom. At present I teach Chinese national IT and science teachers how to facilitate lessons in a bilingual classroom. The Board of Education is preparing to house its schools with nationals. Native English-like pronunciation is no longer a grand concern with English becoming, dare I say, having already become a Lingua Franca. Of the MBA students and corproate trainers I have taught over the years, one thing stays constant. They tell me they can't understand a word their colleagues are saying because everyone seems to have an accent; e.g., Chinese-BrE, Japanese-AmE, German-Australian English, and so on and so on and so on. :lol: The days of communication have begun!
2. Do you think on-line English schools will become more popular?
=> Yes, I do. MSNers and the like, all, will soon be audio-video chatting in English. Why not? If you look at what people are doing today in their fee time and at work, they're chatting on-line and messaging by phone. Add sound and picture to on-line chatting and Wow! Even better!
3. Is it real to see computers in the classrooms instead of teachers?
=> On-line courses have virtual classroom; they work; people sign-up. It's convenient. However, North American studies have shown that males don't do as well in virtual classrooms, whereas females excel. It has something, or rather everything to do with varies kinds of competition. Males tend to seek it, generally speaking. Moreover, is this real: how's X gonna meet a nice Y in a virtual classroom? :lol:
1- What will be the kind of activities in the classroom? The focus will be on what group work, pair work or will we focus on the individual only?
=> All three, of course. Variety is the spice of life.
2- What will be the relationship between pupils and teachers, will the role of the teacher exclude or there won't be a role at all?
=> We learn through and from experience. Teachers are experienced or, at least, they're supposed to be :lol:. It's a reciprocal relationship. The question is, what will a teacher be in the future? Computer programs? Why not? Books did it centuries ago. People who want to learn find a way to do it.
3- How will the input change? Will the contents of curriculum be based only on computers?
=> First, humans write software, even computer generated, artificial intelligence (AI) programmes. At present there are more linguists working in AI than there are working with humans. :lol: There's a new breed about the place, IT linguists, and they're more concerned with how to accommodate language usage by navigating around the exceptions to the rules laid down over the centuries. You know the ones that speakers don't seem to care about these days? Those linguists are the true descriptivist and it'll be the results of their labour that will change the computer-based language programmes we know today for the better.
4-Will the blackboard be history and will pupils see it only in museum?
=> I doubt it, but then again, you never know. Recent studies on gestures by math and science teachers have shown that students learn more effectively when teachers gesture while they are speaking; that's using the blackboard and/or the white one too. As for PPTs, powerpoint presentations, which are all the rage right now, they aren't all that effective even with a laser-wand. Think of it this way, when you have difficulty explaining something to some one, what's the first thing you look for? A pen and a piece of paper, right? Ah, the board with stay, but hopefully someone will invent better writing tools. Those markers! That chalk! Not good for your health.
All the best. :-D
