Almost middle school students have a tendency to hate appreciative study by spoken language. This trend is one of their developmental tasks of aesthetic cognition. On the other hand, as was pointed out by L,S.Vygotsky, in the awkward age, they develop their own conceptual thinking. For enhancing this thinking, they have to have a trainning by written language. So in this study through the appreciative study of "Mona Lisa" by written language, I analyzed their writings based on M,J.Parsons's theory. As a result it came out that many of their writings were higher level than their spoken words. From this result it raised to the surface of "the Zone of Proximal Development (ZPD)" in appreciative study by written language.
