Much of teaching can be quite routine because both the material and the sorts of difficulties commonly encountered by people new to the material are familiar. But if the classroom is not to become merely another spiritual desert in the institutionalized existence of children born to late modernity, the teacher needs to maintain an openness both to the material and to the students. In the classroom, the language through which curricular knowledge lives combines with the minds of students to constitute a field of experience in which the teacher must act as a participant if he is not to rigidify and die, hardening into a mere enforcer of a system.
Symptoms of such a death include the repetition of linguistic formulas in response to questions, the assertion of bland moralisms by way of escaping uncomfortable facts, and the inability to provide concrete illustrations of whatever he is talking about and talking about and talking about. Dogmatism and refusals of the Question are the hallmarks of ideological systems, which are never true but always opposed to truth.
All our systems are wrong, to the extent that they obscure reality by erecting between us and the real world a second reality of language, routinely protected by interdictions on the asking of questions. Nearly all school reform programs are, of course, such systems. Schooling in the age of reform has made both the life of the mind and the life of the spirit increasingly difficult, and we have few public forums where people can discuss education at the level of reality. A staff that has been sufficiently cowed into unreality will, at the end of enervating hour or two of what is called professional development, have no questions. Institutions governed by ideology do not entertain questions aimed at the premises or the telos. Experienced practitioners recognize this and suffer the scotosis in silence.
The school change industry recruits participants who yearn to be a stars in the professional society which their studies or their position have opened for them. The usual panoply of goods is available to those who are willing to play: travel for conferences and site visits, release from mundane chores to sit at the big table, public praise, professional opportunities. Successful school reform leaders and consultants often have a fascination with conceptual schemes, and they mistake their ability to become fluent in such schemes for a grasp on reality.
As they master a second reality—the linguistic machine that underlies the reform plan—their sense of truth begins to shift and deform. Instead of accurate representations of the situations that practitioners actually face, they begin to judge as true those statements that are coherent with the conceptual scheme they have adopted. It can take considerable cognitive power to master complex conceptual schemes, such as Marxism or positivism, and some consultants find real intellectual pleasure in knowing their complicated things and in putting their knowledge on display.
Still, dogmatism is a formidable obstacle to anyone looking for truth and it is also the eternal enemy of teaching and learning.
