The purpose of this paper is to review the developments of the mass lecture system in undergraduate courses in many university. In Japan, especially, lecture of 100 students or more are not uncommon in humanities and social sciences subjects. Under this circumstances the attitude of students in large lectures is deteriorating. The educational effect of mass lectures is limited unless interactive educational technologies such as audio visual methods or demonstrations are employed feedback communication channels between the professor and students. The German sociologist J. Habermas emphasized the rationality of communication must be to develop mutual understanding and agreement, but most of lectures are insufficient from this view point. Academics are major changes in what they teach, new methological approaches to the way they teach and trends in the needs of students of the new generation. This paper will also introduce means for improving teaching softwear for higher education (EDUCOM/NCRIPTAL) in the USA in 1980-1990. Good softwear can be used to structure and connect information based on the context. The training of academic personnel and the study of teaching methods in mass undergraduate education same as the UK and the USA is necessary in Japan.
