Taming the Jungle of Formulaic Language for Learners: Applying StringNet Lexical Knowledgebase to EFL Academic Writing Barry Lee Reynolds National Central University Jhongli, Taiwan
Outline StringNet Navigator Implementation: Pilot Study Preliminary Results Conclusions Q&A
Inspiration Behind StringNet Navigator Inventors of StringNet – Prof. David Wible & Dr. Nai-Lung Tsao Why was StringNet Navigator created? – To solve a problem for learners – Previous work found “word usage” the most common error reported – Can be solved by sending students to: Grammars Dictionaries Concordancers – StringNet Navigator is a bridge between grammar and vocabulary

Background Taiwanese students do not have much need for English till graduate school where they are: – Expected to read and understand scholarly articles from their future areas of expertise – Add to this community of research by writing academic journal articles and conference papers – Write their theses or dissertations in English
Participants Industrial management graduate students (n = 23) voluntarily enrolled in English self-learning classes Split into five classes of 4-5 Ss each based on English ability (low, intermediate, high) determined by their graduate institute
Methods Students were taught text structure, a method found to positively facilitate ESL reading comprehension (Carrell, 1985). Introduced to StringNet Navigator (Tsao & Wible, 2009; Wible & Tsao, 2010; 2011) and its features Given a reading and writing task incorporating StringNet Navigator
Reading & Writing Task 1.Each student was given a different ‘core’ paper from the field of industrial management with the abstract removed. 2.Students were taught text structure during the first two classes and asked to individually read his or her paper after class. 3.During the next three classes students shared paper contents during in-class discussion. 4.During the seventh class students individually wrote an abstract for his or her paper and then gave it to the teacher. 5.During the eighth class students were taught how to use StringNet Navigator and its features. 6.During the ninth class abstracts were returned and students told to select words from the abstracts as queries for StringNet. Students revised and handed in revisions before the end of class. 7.In the last class students shared their experience of using StringNet Navigator to aid revision of their drafts.
Discovery of Noun Countability *‘many researches have shown’ *‘much researches have shown’ Subsequent queries of: ‘research’, ‘many’, ‘many researches,’ ‘much’, and ‘show’ revealed countability of ‘research’ Triggered revisions to ‘research has shown that’ and ‘previous research has shown’
Discovery of Substitutability (1/2) Subsequent queries of: ‘study’, ‘develop model’ and ‘literature’ revealed substitutability through [adj] slots. Example 1 – ‘[adj] studies have shown that’ – Triggered the change to ‘many’, ‘several’, or ‘numerous’ studies have shown that Example 2 – ‘develop a [adj] model’ – Triggered the revision ‘dynamic’, ‘statistical’, and ‘mathematical’ model
Discover of Substitutability (2/2) ‘*The literatures on the past used’ – The n-gram ‘[adj] literature on the [noun sg]’ trigged: ‘existing literature on the subject’ – Students also commented on the substitutability of the [adj] in that ‘published’ and ‘recent’ were other possibilities
Article Errors *’or so called the taxonomy’ *’forms taxonomy of’ *’based on taxonomy’ Queries of the words ‘taxonomy’ and ‘so called’ revealed the pattern and fixed expression – ‘[art] taxonomy of’ – ‘the so called’ – Revisions triggered included: ‘or the so called’, ‘forms a taxonomy of’, and ‘based on the taxonomy’
Conclusions Students were able to successfully self-correct several writing errors Students’ reactions to StringNet varied by English ability – Higher level learners felt StringNet Navigator was very helpful – Lower level learners felt overwhelmed Which words should be searched? How to interpret results? – Intermediate learners Claimed similar difficulties as lower level learners Able to successfully self-correct errors when suggested queries were pointed out to them
