Providing lifelong education through distance education system has become one of the most important roles in higher education. But currently fewer systems can provide one good teaching environment for the instructor to know the feedback from learners and conduct the evaluation of their learning process in real time. It is difficult for the instructor to instantly adjust his lesson during class. In order to provide one face-to-face teaching environment for the instructor, the paper proposes one instructor-oriented interactive prototype system. The prototype may provide one virtual classroom, just like one traditional classroom. The instructor may instantly know who is engaged, who is distracted. In order to improve the teaching & learning efficiency and learners? interests, the problem-based teaching technology is also introduced. Moreover, the shared electronic board will be provided for all participants, which will improve the freedom of teaching and learning.
