The new model is the highly interactive（互动的）learning model. We could also call it the conversational model, or the tutorial model. It is computer based, with the interaction between the student, or a small group of students, and learning programs are like the conversation between a student and a skilled tutor. Distance learning will be the main delivery method. Student interaction with the learning material on the computer will use the student's natural language; it will seem like a conversation between a student and a human tutor. This is the key point of highly interactive, or conversational, learning units. Programs will ask questions in the student’s native language, and respond reasonably to free-form student input. Multiple choice and pointing will seldom be used; they often do not allow individualization (个体化) of education. An important aspect of this model is that the computer will frequently store information about the student, about problems and about how far individual students have progressed. These records will be used often within the programs. Thus when a student returns to the learning activity, the computer knows about that student and knows where to begin the new part. Global education is critical for the future, to get rid of poverty, corruption (腐败), violence and war, to solve major problems such as the lack of drinkable water, and to insure a happy life for all. Education should no longer be limited to the wealthy of the world, but should be available to everyone. In the new distance learning environment learning can take place in markets, libraries, public buildings, learning centers, and the home. Gradually schools and universities will play a smaller role in learning, both because better learning can be delivered through such highly interactive material, and because such learning will be less costly for the individual student. Motivation (动机)is particularly important in a mastery-based distance learning, as the usual threats of traditional classrooms such as that of low grades are no longer possible. Voice input will probably be the mode(模式) for this interaction. The new voice input systems from several companies are useful, cheap, and speaker independent in highly interactive learning. Keyboards may not be needed. Speech is a natural way for humans to communicate. Students will work in small peer groups, about four. Other contacts with people, learning circles, will be possible, directly or electronically. 68. What is not the new model also called?
