Abstract

One important element in academic writing is coherence. Coherence can be described as logical connection of ideas. To achieve it a writer needs to employ different techniques such as using transition signals to relate ideas or using pronouns to refer to key nouns. However, putting all coherence devices together to create a good piece of writing is a challenging task, especially for students who do not acquire extensive skill in writing. Therefore, this study aims at investigating how university students use coherence devices in their writing and what problems they have when applying them. To conduct the research four coherence techniques explained in textbook: Writing Academic English Level 4 (4th edition) written by Oshima and Hogue (2006) were used as a key reference in the study. The techniques consist of repeating key nouns, using consistent pronouns, using transition signals, and arranging ideas in logical order. In addition, 30 opinion essays written by fourth year students at a state university were randomly selected for the analysis. The results and discussion of the study will be further discussed in the conference’s presentation.

Keywords: Academic Writing, Coherence, Coherence Techniques, Coherence Devices

1. Introduction

Of all the four skills of English writing seems to be the most difficult for learners of English as a foreign language (EFL) due to the complexity of writing process. According to Knapp and Watkins (2005), learning to write is a difficult and complex series of processes that require a range of explicit teaching methodologies throughout all the stages of learning. For this skill writers need to verbalize their abstract ideas in their brain into a written form by paying attention to many things (idea, concept, vocabulary, and grammar) (Khunaifi, 2015). This means writing requires writers to use substantial effort as they have to learn the complicated process and combine several skills efficiently in order to communicate their ideas in written form.

For academic writing one important element that is always taken into account in writing is coherence. Coherence refers to the flow of ideas; that is, the movement from one sentence to the next must be logical and smooth (Oshima and Hogue, 2006). Thornbury (2002) sees coherence as capacity of a text to “make sense. In other words, sentences in a text need to be connected logically to make the text meaningful and can be understood by readers. To achieve coherence, writers need to employ different methods such as repeating key words or phrases, using pronouns to link sentences. However, many foreign language learners find difficulties in making their writing coherent. From teaching English academic writing to Thai university students for many years, the researchers found that many of them, though having some knowledge about coherence, could not apply coherence devices correctly and efficiently. Therefore, this study was conducted to examine the use of coherence devices in students’ writing with the purpose to find out how they applied the devices in their writing and what errors occurred when applying them. Discovering results of the study might enable the researchers to find solution to help students to achieve coherence in their writing.

2. Methodology

2.1 Sample The sample of the study was 30 fourth year undergraduate students of the School of Architecture and Design (SoAD) of King Mongkut’s University of Technology, Thonburi (KMUTT), Thailand. All enrolled in LNG 107: Academic Reading and Writing which is a compulsory English courses of SoAD. Their English proficiency levels ranged from intermediate to upper intermediate (due to their standardized test scores submitted to SoAD during their enrollment). Based on the scores, their English skills were supposed to be good even though they were not English-major students. 2.2 LNG 107: Academic Reading and Writing The course is one of compulsory courses for students who study in international programmes of KMUTT. It aims at developing learners’ academic reading and writing skills. Students will learn to write different types of essay and use references and citations throughout the writing process. After studying this course, the students are expected to be able to communicate their ideas logically and write well-organised essays with appropriate citations. 2.3 Instrument and data analysis Thirty opinion essays of the same topic written by the abovementioned students as their final examination were randomly selected for analysis. The controlled topic for this exam was “In your opinion, what skills do you need to succeed in online learning?” It was purposely used to correspond with the situation that the students were encountering at the time when teaching and learning methods were suddenly changed from physical classroom to online learning due to the covid-19 pandemic. To analyze the use of coherence devices in those essays, the researchers employed the methods explained in the book “Writing Academic English Level 4 fourth edition” by Oshima and Hogue (2006) which was used by the researchers for teaching LNG 107 course at the university. According to Oshima and Hogue (2006), there are four coherence devices to help writers to achieve coherence in academic writing: 2.3.1 Repeating key nouns and using key noun substitutes Repeating key nouns of the written topic is the easiest way to achieve coherence. However, there is no fixed rule about how often to repeat key nouns. If writers do not want to repeat a key noun again and again, they can use key noun substitutes i.e. synonyms or expressions that contain the same meaning. 2.3.2 Using consistent pronouns When using pronouns, writers must use the same person and number throughout their writing.

2.3.3 Using transition signals They are words and expressions that guide readers from one idea to the next. There are several different categories of transition signals to serve different purposes of use. The types used in this study are listed below: 1) To list ideas in order of time and importance such as first, first of all, next, most important 2) To add a similar or equal idea such as and, in addition, moreover, as well, besides 3) To add an opposite idea such as but, however, on the other hand, nevertheless 4) To explain or restate an idea such as in other words, that is, in particular 5) To make a stronger statement such as in fact, indeed 6) To give another possibility such as or, on the other hand, otherwise 7) To give an example such as for example, for instance 8) To express an opinion such as in my opinion, in my view 9) To give a reason such as for, because, for this reason 10) To give a result such as so, therefore, thus, as a result 11) To add a conclusion such as to conclude, to summarize, in conclusion 2.3.4 Arranging ideas into logical order They are words and expressions that guide readers from one idea to the next. There are several Arranging ideas into logical order – This technique helps writers arranging and discussing their ideas in logical order such as chronological order and logical division of idea.

3. Findings and Discussion

From the study, it was found that most students used cohesive devices in their writing. These devices were repeating key nouns, using consistent pronouns, using transition signals, and arranging ideas in logical order as listed by Oshima and Hogue (2006). However, each student applied the devices differently due to their own writing styles and preferences. The use of each device is discussed below. 3.1 Repeating key nouns and key noun substitutes Oshima and Hogue (2006) explained that one technique to establish coherence and unity in English writing was repeating key nouns. As the main topic for the opinion essay assigned to these 30 students was ‘online learning’, most students unavoidably used the word as their key noun. Moreover, they also knew how to substitute the key nouns with synonymous words (key noun substitutes). Table 1 below lists down the frequency of the use of key nouns while Table 2 shows the key noun substitutes that students chose in their writings to replace the word ‘online learning’.

Table 1 The number of students with the different frequency of key nouns use

Key noun 3 uses or 4-6 uses 7-9 uses 10-14 uses 15 uses or fewer more Online learning 6 students 11 students 9 students 3 students 1 student Students 9 students 5 students 5 student 6 students 5 students Skills 3 students 6 students 2 students 2 students 0 student

Table 2 The number of uses of most used key noun substitutes to replace 3 key nouns: online learning, student and skill

Key noun substitutes No. of Key noun substitutes No. of Key noun substitutes No. of for ‘online learning’ use for ‘students’ use for ‘skills’ use Online class 31 Learners 25 Factors 3 Online platform 14 Children 12 Abilities 2 Online education 9 People 5 Online classroom 6 Kids 5

It is clearly seen that students knew that repeating key nouns and using key noun substitutes are critical in writing as it helps remind readers the main topic being discussed. As stated by Halliday and Hasan (1976), Oshima and Hogue (2006), and Tanskanen (2006), repetition of key words and the use of their synonyms are one important technique of creating coherence in academic writing. From Table 1, the word ‘online learning’ was used the most as it was the topic of the writing and 20 students used it repeatedly for 4-9 times in their writings. Meanwhile, Table 2 reveals the words ‘online class’ and ‘online platform’ seemed to be the most popular key noun substitutes among the 30 students with the number of use of 31 and 14 respectively, followed by ‘online education’ and ‘online classroom’. For the key noun ‘students’, the words ‘learners’ (25 uses) and ‘children’ (12) were most used as its key noun substitutes. Meanwhile, the key noun ‘skills’ had only the words ‘factors’ (3 uses) and ‘abilities’ (2 uses) as its substitutes. It can be concluded that students knew how to use this device of repeating key nouns and key noun substitutes to have coherence in their writing. However, there are few students who kept using the key nouns repeatedly with very few uses of key noun substitutes; this might be because these students tried to avoid complex grammatical rules—such as, in this case, how to use the right key nouns—which they did not feel confidently enough to write (Touchie, 1986). 3.2 Using consistent pronouns Another device to achieve coherence in academic writing is the use of consistent pronouns (Oshima & Hogues 2006). In the students’ 30 writing pieces, the use of consistent pronouns were found throughout each piece. Table 3 below shows the most used pronouns including 1st personal pronouns, 2nd personal pronouns and 3rd personal pronouns.

Table 3 The number of use of most used personal pronouns in students’ writings

Pronouns 1st most used 2nd most used 3rd most used 1st personal pronouns we (57) I (29) us (15) 2nd personal pronouns you (53) one (7) yourself (4) 3rd personal pronouns it (75) they (29) them (25)

From Table 3, it is clearly seen that students seemed to use the 3rd personal pronouns the most, followed by the 1st personal pronouns and 2nd personal pronouns, respectively. The pronoun ‘it’ was of the most popular use (75 uses), followed by ‘they’ (29 uses) and them (25 uses). For the 1st personal pronouns, the pronoun ‘we’ was of the most popular use (57 uses), followed by ‘I’ (29 uses) and us (15 uses). Regarding the 2nd personal pronouns, the pronoun ‘you’ was of the most popular use (53 uses), followed by ‘one’ (7 uses) and yourselves (4 uses). For the reason that the 3rd personal pronouns became the most used ones among the three personal pronouns, it may be because this type of personal pronoun can refer to things, ideas, situations, concepts or even previously mentioned items in each writing (Swan, 2017) while the 1st Proceedings of The 7th Regional Conference on Graduate Research 16 January 2021, Sripatum University, Khon Kaen Campus, Khon Kaen, Thailand 571

and 2nd personal pronouns can be referred to only persons. This can be clearly seen in the referents of each type of pronoun the students referred to. For the 3rd personal pronoun ‘they’, students tended to refer it to plural nouns such as students, teachers, people, courses or skills while they referred ‘it’ to various singular nouns of concrete and abstract nouns. A number of examples included online learning, time, data, the Internet, technique or even the COVID-19 situation. It is seen that students knew how to use different types of pronoun for different referents. On the other hand, more than half of students faced challenges in using these pronouns correctly in terms of lexical and grammatical aspects. The researchers did the analysis of students’ use of different types of pronouns and found different patterns of errors which can be categorized into 5 types and some examples of each pattern are discussed in the following. 3.2.1 Using ‘it’ to refer to a plural noun (5 cases) Example 1 We are facing the new tools for learning process. Even though, it is hard during the start, it come with a lot of benefit if we get used to it. [This writer clearly used ‘it’ to refer to ‘the new tools’ which is a plural noun.] 3.2.2 Using ‘them’, ‘they’ or ‘themselves’ to refer to a singular noun (17 cases) Example 2 One can have access to more information online since most of them are in English. [Instead of using ‘it’, this writer in fact used ‘them’ to refer to ‘information’ which is an uncountable noun. Therefore, using ‘them’ for such referent is not grammatically correct.] Example 3 The ministry of higher education lack of understanding their citizens in case of the connection preparation and the devices for learning that mentioned above. [Instead of using ‘its’, this writer used ‘their’ to refer to ‘The ministry of higher education’, a singular noun, which is not grammatically correct.] 3.2.3 Using both the first personal pronoun ‘I’ or ‘we’ and second personal pronoun ‘you’ in their essays to address their readers / message receivers. (8 cases) Example 4 Computer Literacy is also the one problem that I need to succeed more better. You cannot expect to do well in an online class unless you are computer literate. [This writer used ‘I’ (1st personal pronoun) in the earlier sentence to relate himself or herself to an action. Still he or she then changed the subject of the following sentence to ‘you’ (2nd personal pronoun) even though the flow of information still continues from the earlier sentence that the action in the second belongs to the same subjects of the first.] Example 5 For example, if we have used ‘Microsoft team’, it is easier for you once you try to use ‘Zoom meeting’.[This writer used ‘we’ (1st personal pronoun) in the subordinate clause in the beginning of this sentence to relate himself or herself to an action. However, he or she then changed the subject of the following sentence to ‘you’ (2nd personal pronoun) in the following main clause despite the action in the main clause related to the same subjects of the subordinate clause.] 3.2.4 Using the second personal pronoun ‘you’ to refer to students in general in their essays to address their readers / message receivers. (4 cases) Example 6 The first and most important reason to help students be successful in online learning is to keep your self-motivation and self-discipline all the time. The second thing that can help you to succeed in the online class is you have to has space to study properly.

[This writer used ‘your’ and ‘you’ (2nd personal pronouns) to refer to the referent ‘students’. In fact, he or she should change these 2nd personal pronouns to 3rd personal pronouns: their, them and they, respectively.] Example 7 Another reason is communication skills improvement, in an online learning program, students won’t have as much access to your professors as you would in a more traditional program. With an online class, students get to control their learning environment, which helps you develop a deeper understanding of classes. [This writer used ‘your’ and ‘you’ (2nd personal pronouns) to refer to the referent ‘students’. In fact, he or she should change these 2nd personal pronouns to 3rd personal pronouns: their, they and them, respectively.] 3.2.5 Referring pronouns to unclear referents (8 cases) Example 8 …could it be better if the government helps and try to support the students to more touchable with online education to make an equalization of the education system. Moreover, it can increase or support students in understanding the lesson more. Seeing by using the e-book or videotape recorder, it will be better enough. [This writer used the pronoun ‘it’ three times in this example; however, it is unclear which referent— 1) online education, 2) an equalization of the education system or 3) seeing by using the e-book or videotape recorder— that the pronoun ‘it’ in the last sentence refers to.] From the mentioned errors in 5 different patterns, it is clearly seen that most students seemed to have problems in the following categories: 1) using ‘them’, ‘they’ or ‘themselves’ to refer to a singular noun (17 cases); 2) Using both the first personal pronoun ‘I’ or ‘we’ and second personal pronoun ‘you’ in their essays to address their readers / message receivers (8 cases); 3) Referring pronouns to unclear referents (8 cases). One possible reason to explain these patterns of errors is L1 interference or language transfer. This type of error is identified by Richards and Schmidt (2010) and Brown (2007) as the one caused by the interference of the native language of users— for these students. That is, the native language of learners has influence on their use of the second language, which is English in this study. In Thai language, native users of the language generally refer to any 3rd personal pronoun as the word ‘kháw’. It can substitute for both male and female 3rd personal pronouns, either in singular or plural forms (Smyth, 2002). This leads to a possible explanation why there are 17 cases of students having used ‘them’, ‘they’ or ‘themselves’ to refer to a singular noun as per the L1 interference. It can be assumed that they had translated their ideas in Thai into English when writing essays. Another possibility of these errors is the students’ lack of inconsistency when using pronouns in their writings. While writing, students tended to focus on many issues in limited amount of time such as development of the main idea, word choice, grammar, coherence and cohesiveness and their own stress to do their best (Wirantaka, 2016). In other words, they have already known how to correctly use pronouns but their outcomes turned out grammatically incorrect. This may be considered the type of error called ‘slips’, caused by the nervousness, tiresome or other intrinsic conditions of students that affected their writings (Harmer, 2012). 3.3 Using transition signals According to Oshima and Hogue (2006), using transition signals to show how one idea is related to the next is one powerful device to create coherence and unity in English writing. All of 30 students in this study used this device in their writing. As a result, a variety of transition signals were seen when analyzing the piece of writing of each student. Table 4 below shows 11 types of transition signals used and the three most used transition signals of each type.

From Table 4, it is clearly seen that students used transition signals to connect ideas in their writing together to create coherence. After analyzing all students’ writings, it was found that there were 11 types of transition signals in students’ essays. Also, it was found that the most frequent signals use by the students was ‘and’ (49 uses) and the frequent type of signals was ‘to add a similar or equal idea’ (117 uses) which is in accordance with the study of Nugraheni (2015). Meanwhile the transition signals ‘to list ideas’ (82 uses) and ‘to add an opposite idea’ (56 uses) were the second and third most used ones in the study. In addition, the transition signals that were most used in the essays were simple connectors, such as ‘and’, ‘but’, ‘because’, ‘so’ etc. as seen in Table 4. In general, students were found to use this device most frequently despite some errors related to the rules of using each type of transition signals. One clear example is the use of coordinating conjunctions such as ‘so’, ‘and’ or ‘but’. A few students used these conjunctions in the beginning of a new sentence. In fact, they function as connectors that connect equal elements such as two main clauses in a compound sentence. As a result, this type of use is considered grammatically incorrect. 3.4 Arranging ideas in logical order The last device to establish coherence in writing is the technique called arranging ideas in logical order. It means writers need to display their ideas “in some kind of order that is logical to a reader accustomed to the English way of writing” (Oshima & Hogue, 2006, p.34). There are several kinds of logical order in English. One of them is logical division of ideas where writers normally divide their topic into parts to discuss separately. For this study, it was found that all 30 students used this device to arrange and discuss their topic ideas in sequence. They also knew how to use related transition signals in the right category, ‘to list ideas’ (82 uses) which in fact was the second most used type of transition signal in this study. In the meantime, the signals in this category mostly used are

4. Conclusion and implications The findings of the study answered the questions on how students applied coherence devices in their writing and what errors occurred when they applied them. The results of the study showed that most of the students used all the four coherence techniques in their writing stated by Oshima & Hogue 2006. Overall, students were found to use transitional signals the most although some of them produced some errors using them. Meanwhile, for the use of repeating key nouns, a few students kept repeating the key nouns without using any substitutes or hardly used substitutes. It can be concluded that the more students repeated key nouns in their writings, the less they used substitutes. This behaviour might be explained as ‘avoidance’. Due to Touchie (1986), “some syntactic structures are difficult to produce by some learners. Consequently, these learners avoid these structures and use instead simpler structures” (pp.78-79). Another coherence device frequently used in the essays was the use of consistent pronouns. However, more than half of the students made significant errors when using pronouns to refer to things, persons, and actions as well as to address their readers. This can be clearly seen from the examples provided in the findings. This means using this device was rather problematic for Thai students and also complies with the study of Wilfitri and Fatimah (2020) as they found out that some students replaced key nouns with wrong pronouns and had the inconsistency in using the singular and plural form one noun. One possible cause of this type of error was the interference of their mother tongue (L1 interference) and slips as mentioned above. In sum, these findings show that students in general knew how to use all four coherence devices to establish cohesiveness in their writings. However, the use of each device contains some errors particularly the use of consistent pronouns. This has led the researchers to realize more emphasis on the use of cohesive devices especially the use of consistent pronouns. Another possibility for researchers is the further study on how to enhance students’ competency regarding the use of pronouns in their writings.
