An Analysis Of Interactional Metadiscourse Devices In Communication Arts Research Articles

Abstract
This corpus analysis is a quantitative study which intended to investigate the uses of four main interactional metadiscourse devices including fourteen sub-devices in the introduction and the discussion sections of the twenty communication arts research articles taken from Online Journal of Communication and Media technologies by applying ‘AntConc’ software and PASW 18.0. The findings reveal that the three most frequently useddevices (X per 1000 words) in the introduction parts are attitudinal marker adjective (10.26), booster verb (5.56), and modal verbhedge (3.96) while the three most frequently found devices in the discussion sections are attitudinal marker adjective (18.88), modal verb hedge (11.51) and booster verb (9.14). There are nine sub-interactional metadiscourse devices among each of which significant difference (P) exist in both introduction and discussion sections. These are attitudinal marker adverb (<0.01), attitudinal marker adjective (<0.01), booster verb (<0.05), booster adverb (<0.05), booster adjective (<0.05), modal verbhedge (<0.001), hedge lexical verb (=0.001), hedge adverb (<0.01) , and hedge adjective (<0.05), while another five sub-interactional metadiscourse devices; self-mention, attitudinal marker verb, attitudinal marker noun, hedge noun, and hedge phraseology are found to have no significant difference between the use of each device in the introduction and discussion sections. The results also revealed that low and positive relationships exist among thirteen devices. One device which has no relationship with others is attitudinal marker verbs.
