As this paper was a very close version of “Investigating task difficulty: learners’ and teachers’ perceptions” by Dr. Parvaneh Tavakoli (published in “International Journal of Applied Linguistics”, Vol. 19, No. 1) in terms of content, research design, analytic framework and research findings without appropriately referencing resources used or obtaining author's consent, the paper was considered an infringement to the author's copyright and therefore has been permanently removed from this journal. Please note, as "Applied Research on English Language", which belongs to the University of Isfahan, has only one official website (, if you see this paper (in print or any other format) elsewhere, please do not use and/or quote it since the manuscript is not viewed as a published paper by University of Isfahan anymore.
