The well-established affiliation of metadiscourse research tradition to the philosophy of ESP raises some inevitable expectations on how much and how well the concept has been geared to meet the practical necessities of academic writing pedagogy. In light of such an expectation, a corpus of 35 academic writing coursebooks published during the last three decades was evaluated in terms of the possible realizations of key resources of interaction in pedagogical tasks. Due to its theoretical rigor and analytically operationalized nature, Hyland’s model of metadiscourse (2005a) was taken as the guiding framework for the current evaluation. The quantitative findings emerging from the analysis of the corpus did not sound sufficiently promising, suggesting that those theoretical developments have not yet been ideally translated into pedagogical designs; however, the rich range of resources identified in the tasks (i.e., the 55 categories emerging from the evaluation of the corpus) suggest that the rigorous tradition of research in metadiscourse has contributed to the effective operationalization of the concept for pedagogical objectives. It has been argued that through the effective introduction of the concept of metadiscourse into pedagogical designs and its appropriate operationalization, novice participants of academic/scientific discourse communities would be enabled to redefine the nature of academic communication and get rid of a large number of misconceptions which have become fossilized through long years of the dominance of positivistic thinking.
