In analogy to archeology, pedagogical reflection doesn't deal with an objective truth or evidence but with a subjective construction which can become - sometimes only for a limited period - a shared truth in a given social context.
For example, an archaeological discovery like a female figurine can be seen as a religious object, or a symbol for fertility, or evidence for a matriarchal society, depending on an archaeologist interpretation of the context where it has been found and on his specific view.
In archaeology like in education different people will tell different stories about a situation or an artifact, a text, an answer, a drawing, an excavated object etc. There is no immediate self-evident nature of a learning outcome as there is no self-evident nature of an archaeological discovery. Decontextualized they become more and more difficult, sometimes even impossible to interpret and the stories told are closer to speculation than to reality.
If from a certain point of view there seems to be an objective evidence than, from a different point of view, others could well have found a different truth. Does this mean that anything is equally true or that the truth is always a bit of everything?
I don't think that extreme relativism, which I encounter frequently in my work with schools, is helpful. Most of the time it is a way to avoid to take a stand, to express an opinion for or against an interpretation and in consequence to avoid that ones opinion could be refuted by others. And, extreme relativism is often a way to avoid to make a decision and to be taken responsible for its possible consequences.
In "Towards reflexive method in archaeology : the example at Çatalhöyük" Ian Hodder, a postprocessual archaeologist describes a new aproach in archaelogy based on reflexive startegies that can be used to work your way through negotiated interpretations in a given context. Hodder calls this approach "reflexive method".
He enumerates a set of twelve methodologies and describes four resp. five themes which I think could be applied to education. After having read the following quotes try to read them again with the word "archaeological" substituted by "pedagogical" or "educational":
In analogy to archeology, pedagogical reflection doesn't deal with an objective truth or evidence but with a subjective construction which can become - sometimes only for a limited period - a shared truth in a given social context.
For example, an archaeological discovery like a female figurine can be seen as a religious object or a toy or a symbol for fertility or evidence for a matriarchal society, depending on an archaeologist interpretation of the context where the figurine has been found and on the archaelogist's specific view.
In an educational context, a non-compliant behavior of a student can be regarded differently depending on the situation where this behavior could be observed, and of course the point of view of the observer. The reason for the behavior could be found in the situation itself or be seen in the broader social context that the child lives in.
Reflexivity,
"By this I mean the examination of the effects of archaeological assumptions and actions on the verious communities involved in an archaeological process."
Relationality or contextuality
"The notion here is that meaning is relational. This emphasis is seen in the reflexive attempts to relate findings to a specific context of knowledge production. but the emphasis is also visible in the inter-relations of contextual and artefactual information."
Interactivity
"The aim here is to provide machanisms for people to question and criticize archaeological interpretations that are being made, as they are being made. (...) The prioritizing (sampling) procedures are arrived at by negotiation between staff members. (...) Interactivity is also facilitated ... by the provision of the data base on the Web (...) and by the provision of information in diary and video form that situates the data base and opens it up for critique and alternative interpretation."
Multivocality
"A wide range of different groups often have conflicting interest in the past and wish to be engaged in the archaeological process in different ways. (...) Mechanisms need to be provided so that different discourses can take place."
"An additional theme can be described as "non-dichotomous thinking" that is the breaking down and questioning of categories and boundaries. (...) It is necessary to bridge the divide between archaeology as either science or humanity either history or anthropology, as either objective or subjective."
