Abstract
Degrees of difficulties of teaching subjects and activities in elementary schools and their reasons are studied from self-evaluated answers of questionnaire from elementary school teachers to investigate validity of discipline-centered pre-service curriculum in teacher producing colleges or faculties. Answers from 583 teachers are analyzed by dividing the teachers to three groups of science-oriented group, literature-oriented group and junior college according to their academic carrier. Many results are obtained as follows. Teachers have the greatest difficulties in teaching "music". Degree of difficulties in teaching "science" is greatly different between science-oriented group and literacy-oriented group. Reasons of difficulties on teaching subjects reveals that every subject has its own characteristics from standpoint of teaching. Main reasons of difficulties on teaching through all subjects are insufficiencies of teaching methods as well as teaching contents and difficulties of setting activities and teaching materials in those subjects.
