the pressure exercised bydiscourses that highlight the social dimension of assessment is very strong and pervasive,making it difficult for more exhortative or developmental policies on assessment (Ball et al.,2012) to survive in the polyphonic discursive space of the school. PA3, a policy authority whohas worked as a school teacher, also sees schools as spaces where contradictory discourses onassessment circulate in a paradigm conflict, where the current structure of schools does notfacilitate reform processes either:

Mikhail Bakhtin observes discursive spaces as being in permanent contestation, andutterances as processes of ideological positioning of the self in a historical and cultural context.

After all, the academic disciplines, as they have come down to us, represent an implicit taxonomy that favors analytical reasoning and discursive practices.

Their modes of operating present an image of how thinking takes shape in and through material and embodied practice

Knowles, however, does not make this point by means of an argument expressed in language, like Barad does, but by means of a material discursive formation

The elements of IBIS are: issues (questions that need to be answered), each of which are associated with (answered by) alternative positions (possible answers or ideas), which are associated with arguments which support or object to a given position; arguments that support a position are called "pros", and arguments that object to a position are called "cons".[1][8] In the course of the treatment of issues, new issues come up which are treated likewise.[9][10]

t "[ilf Northrop Frye should write an essay attacking archetypal criticism, the article would by definition be of much greater significance than an article by another scholar attack- ing the same approach" (Schaefer 5). The reason, of course, is that the approach is not something in- dependent of what Northrop Frye has previously said about it; indeed, in large part archetypal criticism is what Northrop Frye has said about it, and therefore anything he now says about it is not so much to be measured against an independent truth as it is to be regarded, at least potentially, as a new pronouncement of what the truth will hereafter be said to be

The initiation of a discursive practice,unlike the founding of a science, overshadows and is necessarilydetached from its later developments and transformations. As aconsequence, we define the theoretical validity of a statement withrespect to the work of the initiator, whereas in the case of Galileoor Newton, it is based on the structural and intrinsic norms estab-lished in cosmology or physics. Stated schematically, the work ofthese initiators is not situated in relation to a science or in thespace it defines; rather, it is science or discursive practice thatrelate to their works as the primary points of reference.

ficially,then, the initiation of discursive practices appears similar to thefounding of any scientific endeavour, but I believe there is a funda-/ mental difference

other hand, Marx and Freud, as'initiators of discursive practices', not only made possible a certainnumber of analogies that could be adopted by future texts, but,as importantly, they also made possible a certain number of dif-ferences. They cleared a space for the introduction of elementsother than their own, which, nevertheless, remain within the fieldof discourse they initiated. In saying that Freud founded psycho-analysis, we do not simply mean that the concept of libido or thetechniques of dream analysis reappear in the writings of KarlAbraham or Melanie Klein, but that he made possible a certainnumber of differences with respect to his books, concepts, andhypotheses, which all arise out of psychoanalytic discourse.

The distinctive contribution of these authors is that they pro-duced not only their own work, but the possibility and the rulesof formation of other texts. In this sense, their role differs entirelyfrom that of a novelist, for example, who is basically never morethan the author of his own text. Freud is not simply the author ofThe Interpretation of Dreams or of Wit and its Relation to theUnconscious and Marx is not simply the author of the CommunistManifesto or Capital: they both established the endless possibilityof discourse. Obviously, an easy objection can be made. The authorof a novel may be responsible for more than his own text; if heacquires some 'importance' in the literary world, his influence canhave significant ramifications. To take a very simple example, onecould say that Ann Radcliffe did not simply write The Mysteriesof Udolpho and a few other novels, but also made possible theappearance of Gothic Romances at the beginning of the nine-teenth century. To this extent, her function as an author exceedsthe limits of her work. However, this objection can be answeredby the fact that the possibilities disclosed by the initiators of dis-cursive practices (using the examples of Marx and Freud, whomI believe to be the first and the most important) are significantlydifferent from those suggested by novelists. The novels of AnnRadcliffe put into circulation a certain number of resemblances andanalogies patterned on her work - various characteristic signs,figures, relationships, and structures that could be integrated intoother books. In short, to say that Ann Radcliffe created the GothicRomance means that there are certain elements common to herworks and to the nineteenth-century Gothic romance: the heroineruined by her own innocence, the secret fortress that functions as

I believe that the nineteenth century in Europe produced asingular type of author who should not be confused with 'great'literary authors, or the authors of canonical religious texts, andthe founders of sciences. Somewhat arbitrarily, we might call them'initiators of discursive practices'.
