From the perspective of theoretical research, the extreme orientation of both philosophy and psychology will lead to the contradiction and breaking of knowledge teaching and students' development. Consequently, the development of all the students to be human being would be lost. From the perspective of teaching practice, both the spoon-fed teaching and experience-constructive teaching, either controlling or indulging students, as a matter of fact, lead to the lost of cultivating students to be human being. Analyzing from the perspective of ideology, Herbart's "educational teaching", Dewey's "experience" curriculum and teaching ideology and constructivism make contributions to knowledge teaching. However, they have, constraints. If we cannot understand both their advantages and disadvantages but simply support or deny them, teaching research and practice will go to an extreme.

从理论研究上看，无论是哲学的极端趋向还是心理学的极端趋向，都会导致知识教学与学生发展的对立与断裂，最终是学生发展成人的总体失落；就教学实践看，无论是&独断一灌输式&教学还是&体验一建构式&教学，要么控制学生要么放纵学生，都在事实上引发了学生发展成人的总体失落；从思想认识上分析，赫尔巴特的&教育性教学&思想、杜威的&经验&课程与教学思想、建构主义理论都有其积极贡献，但也各有范围和条件，不能正确看待它们的理论长处和局限，单纯的推崇或简单的否定，都会致使教学研究与实践走向非此即彼的极端化立场。
