Abstract
An essential difference regarding secondary science teachers before World War II between the teacher model of professionalism from higher normal schools and that of liberalism/academicism from the imperial university was whether they received education/training of discipline for the teaching profession. Especially, only the curriculum for higher normal schools included the practical teaching experience/teaching practice that offered the opportunity for developing practical capability for teaching. In this paper, the author has attempted to investigate the historical meaning of the practical teaching experience/teaching practice at the attached secondary schools to higher normal schools before World War II, through the following analysis; 1) Importance of practical teaching experience/teaching practice in education/training in the discipline for the teaching profession, 2) The facts and mentoring in practical teaching experience/teaching practice Through analysing the above-mentioned points, the author has attempted to clarify whether there is a helpful historical inheritance that constitutes a point of reference at the present age.
