“…Key to demonstrating skill development in writing are the text‐analytic measures which researchers utilise. Beyond Issitt's () corpus linguistic techniques, there are a multitude of measures of L2 writing development, including but not limited to T‐unit length (Storch & Tapper, ), the ratio of surface errors (van Beuningen, de Jong, & Kuiken, ), error‐type frequency counts (Han & Hyland, ; Zhang & Hyland, ), use of lexical bundles (Hyland, ), and impressionistic global textual judgements (Archbald, ; Storch & Tapper, ). It is recommended for future studies which track writing‐development from pre‐sessional to the main programme to adopt a range of text‐analytic measures, selected because they cohere with the ‘double duty’ which PSP written tasks and assessment perform: helping students develop their academic language and skills while providing certification that they have reached the required proficiency level (Banerjee & Wall, ; Seviour, ).…”
