Reference Markers in Introduction Section of Undergraduate Students’ Theses: A Corpus-based Systemic Functional Analysis
Cohesion has significant role in academic discourse. This study is conducted to investigate the reference marker used as grammatical cohesive device and why those are realized in the introduction section of the undergraduate students’ thesis. This analysis departs from the grammatical cohesion in systemic functional grammar theory. The AntConc software was used as analysis tool in corpus linguistic method to identify the frequency, lists, concordances and collocations of reference markers. The data source are taken from 90 thesis introduction written by English literature students of Faculty of Cultural Sciences, Universitas Sumatera Utara who graduated during 2017-2019 period and the data in the corpus is 120748 word-tokens. To improve the reliability of the data, the instances of Reference were confirmed by two raters. The findings are personal, demonstrative, and compative references found in the data which are dominated by the demonstrative reference. This domineering demonstrative reference marker explains that the students attempt to give the specification of the information in the data and to refer to the outside world shared between the writer and the reader.
