THE ANALYSIS OF GRAMMATICAL ERRORS OF FIRST YEAR STUDENTS’ ESSAYS

A language learner often faces many linguistic differences, especially if the native language and the target language are from different language families. The current study investigates the grammatical errors made by the first year students of the English Department, Faculty of Letters, Jember University, Indonesia. The data were collected from 30 participants’ essays of Writing 01 class (documentary data) conducted from August to December 2014. Having been identified, the errors were classified into various categorizations, and analyzed based on descriptive-interpretative method to find the possible sources of the errors. The research revealed that the learners committed ten types of grammatical errors, and the six mostly prominent errors were plural form, subject-verb agreement, verb tense, word form, subject/verb omission, and passive voice respectively. This research also showed that the errors mostly resulted from the different linguistic principles of Indonesian and English (interlingual transfer), and partly from the faulty of overgeneralization of English rules (intralingual transfer). The overt influences of Indonesian to English as well as the overgeneralization of English rules can provide the writing teachers and course designers with insightful guidelines for better understanding of the sources of errors, which in turn, can help them to apply the more appropriate approaches to manage the foreign language learners’ errors of the students.


INTRODUCTION
Basically, learning a language consists of active and productive skills.Writing is generally considered to be one of the active or productive skills of language usage.It is considered active and productive because learners have to apply many aspects of language, such as: general knowledge, vocabulary, and grammar in this subject.Writing is also considered very important in every curriculum of university because it is believed that this subject can be seen as a tool for language development, for critical thinking, and for learning in all disciplines.In universities, writing becomes significant because most subjects depend on it.Taking notes, writing essays, answering questions, writing reports, and finally writing thesis also need the help of writing class.The skills presented in writing will also develop the students' skills in acquiring the needed strategies to present the data, to analyze, to interpret, and to make inference from the data collected from their researches (Bacha, 2002).There are some aspects can be evaluated from the students' essays, such as: the content (the information presented in the essays), the organization (the ways of organizing ideas), and the language accuracy (the appropriate and acceptable forms of grammar used in the essay).The content and the organization, however, will be hard to follow if the language (the grammar) they used is not accurate.Accuracy in writing occurs when the language learner conforms to the rules of the target language; and error occurs when it does not.Those rules may be at different levels: pronunciation, morphology, syntax, lexicon, discourse, or sociolinguistics (Carla, 2015).Since the focus of the study is the grammatical errors, the appropriate levels for the errors are morphology and syntax levels made by the students in their essays.

A. Contrastive Analysis and Error Analysis
Concerning to the learner's errors, there are two major approaches to study, namely contrastive analysis and error analysis.Error analysis cannot be studied properly without touching upon the notion of contrastive analysis.Both of them have been commonly recognized as branches of Applied Linguistic Science (Khansir, 2012).Contrastive linguistics has been defined as a linguistic study which concerns with the comparison of two or more languages or subsystems of languages in order to determine both differences and similarities between them (Fisiak, 1981).The contribution of contrastive analysis in the language teaching is the description of the grammatical errors which made up the differences between the grammar of the native language (L1) and that of the target language (L2).In relation to the sources of errors, Bose (2005) explained that one of the sources of the learner's errors is the interference (or transfer, according to Ellis (1997) of his native language which can be depicted as the negative and positive transfer between L1 and L2.The negative transfer occurs when the grammatical forms of L1 and L2 are different, while the positive transfer happens if they are similar.Another attitude to errors is that they are the result of the influence of L1 on the learning process called interference.This process is also based on the fact that learning foreign language is strongly influenced by the habit of the learner's native language (Corder, 1987).
Error analysis, on the other hand, claimed that the learner's errors are not merely caused by the native language because many errors actually made have no parallel with the native language structures (Khansir, 2012).Referring to both contrastive linguistics and error analysis, errors may be caused by both contrastive difference as well as the structures of the target language itself.Richards and Schmidt (2010) and Shekhzadeh and Gheichi, (2011) distinguish between two sources of errors: interlingual transfer and intralingual transfer.Interlingual transfer explains that errors may result from the language transfer of similar rules from the learner's native language to the target language.For example, the incorrect English sentence 'John go to school every day*' was produced as the transfer of his native (Indonesian) language rule 'John pergi ke sekolah setiap hari' in which Indonesian does not have subject-verb agreement.In contrast, intralingual transfer describes that errors are caused by the mutual interference of items in the target language (Keshavarz, 1994) which is also known overgeneralization or ignorance of rule restriction of the target language.Overgeneralization occurs when the learner has mastered a general rule but he does not yet know all the exceptions to that rule (Ziahosseiny, 1999 p. 126).For example, a learner may produce 'He must to go to school*' based on the overgeneralization of the English structure 'He wants to go to school'.

B. Previous Studies
There have been many recent publications in contrastive analysis and error analysis on the errors made by learners of English as a foreign language in many different levels.The study of the morphophonological or syntactic transfer in the acquisition of articles by Syrian speakers was conducted by Sarko (2008) in which he found that they transfer the syntactic properties of L1 into English grammar.Ting et al (2010) investigated the grammatical errors in spoken English of university students in oral communication course who are less proficient in English.The results of the research showed that the five common errors made by the learners are preposition, question, article, plural form of noun, subject-verb agreement, and tense.The result also showed an increase in grammatical accuracy in the students' spoken English towards the end of the course.Next, Isabelli-Garcia and Slough (2012) investigated the acquisition of non-generic definite article by Spanish learners of English as a foreign language which proved that the obligatory use of the definite articles does increase accuracy rates.Further study on morphological and syntactic errors was carried out by Al-Badawi (2012) who investigated phonetic, morphological and syntactic errors made by the undergraduate Saudi students at King Khalid University.
Further publications of contrastive and error analysis on English essays or writing productions as well as translation for non-English speakers (Chinese, Spanish, Arab, Jordan, French, among others) have been conducted by the following researchers.Research on error analysis of Chinese learners of the Korean language manifested errors within learners' written works was conducted by Lee (2010).This research revealed that errors resulted both from the native language transfer as well as from the target language transfer.Zahwareh (2012) investigated the written English errors of tenth grade students in females and males schools in Ajloun, Jordan.This study revealed the grammatical errors occurring in the areas of morphology, function words, tenses, and lexical items.The next study (Sokeng, 2014) presented the discussion of the difficulties that bilingual level 1 Francophone students in the Department of Bilingual Studies of the University of Yaounde 1 face in English.
The analysis of their compositions revealed that the most salient grammatical errors found in the students essays covering the fields of verb tense and form, subject-verb agreement, prepositions, word order, plurality, articles, passive voice, auxiliaries and double negation.These results proved that the teaching and learning of English writing skill of secondary students in Cameroonian primary and secondary schools need more reinforcement and development.Finally, Presada and Badea (2014) conducted a research on the effectiveness of error analysis within the translation classes on the theoretical framework of contrastive and error analysis.This study investigates the most frequent types of errors and their causes.The findings of this research constitute a data base which is necessary to conceive a more effective teaching and learning process that focuses not only on translation classes, but also on the acquisition of English as a foreign language in general.
An overview of the importance of error analysis in teaching English as a foreign language in Indonesia was carried out by Hasyim (2002).This article presented some sample of English sentences containing grammatical errors made by the students and analyzed them based on the linguistic theories.By this discussion, the students are expected to increase their knowledge on their English grammar.A study on phonological errors particularly the English consonantal sounds that do not exist in Indonesian phonetics system produced by English department students was conducted by Tiono and Yostanto (2008).The study revealed that the students produced thirty-four kinds of phonological errors and that the deviations occurred most frequently before, after, or in between vowels.Andi-Pallawa and Alam (2013) also conducted a comparative analysis between English and Indonesian phonological systems.This study proved that some differences of phonemic and phonetic features between English and Indonesian make 20 English Department students of Tadulako University, Indonesia, as the respondents, still have problems in pronouncing English words.Another study on syntax errors made by L2 learners in conversation was conducted by Wiannastiti (2014).This study revealed that L2 learners made some errors in grammar and exchanging information because they are influenced by L1.They tended to transfer from L1 to L2 rather than thinking to create the utterances in L2.
Despite the fact that there are some preliminary researchers on contrastive analysis and error analysis which investigated English errors made by the Indonesian learners of English as a foreign language, researches on English grammatical errors made by the Indonesian-English learners in essays or writing works have received comparatively less attention, if not yet done.This study commences with identifying the unacceptable (grammatical) forms produced in the first task of students' essays.In the second and third writing tasks, a special attention addressed to the students who made unacceptable forms in their first essays, to make sure whether they made ungrammatical forms systematically or unsystematically (errors vs. mistakes, according to Ellis, 1997).The essays with the grammatical errors (made by the students systematically) are considered as the source of the data, and the errors committed by the students were classified into some grammatical types.Next, the errors were discussed and interpreted to find the sources of the error production to widen the learners' knowledge of English and to improve their language accuracy in writing essays.

METHODOLOGY
This is a qualitative research using a case study approach.The case study investigated some grammatical errors made by the learners (Densombe, 2007).The population of the research consisting of 120 students who took Writing 01 classes from August to December 2014.The students were distributed into three classes (A, B, and C).All were new undergraduate students of the Department of English, Faculty of Letters, Universitas Jember (Indonesia) who enrolled in the 2014-2015 academic year.They have been studying English for 6 years in Junior and Senior High Schools, where English is a foreign language, Indonesian is a national language, and they also speak, at least, one local language, e.g.Javanese, Madurese, and Balinese.
There are high similarities in terms of the structures of their native languages the students speak.The languages are only different particularly in the lexicons or vocabularies.
The technique of data collection in this study applied the documentary method, using written material (the students' essays) as a basis of the research (Blaxter et al, 2006: 154).This research was based on the grammatical errors found in the essays and snowballed with the interview data.During the first semester of the 2014-2015 academic year, the students were given some writing tasks on various topics, such as holiday, hobby, sport, and individual experience.The general topics were chosen because they are simple, informative, and clear to be stated which could encourage them to write.The main purposes of these exercises were not to give the information (to answer) themselves, but how the participants expressed their ability to use their English in expressing their ideas.Out of 120 papers (from the first writing task) were found 70 students who made some (serious) unacceptable forms.Ellis (1997) raises the need to distinguish between errors and mistakes and makes an important distinction between the two.He says that errors reflect gaps in the learner's knowledge; they occur because the learner does not know what is correct.Mistakes reflect occasional lapses in performance; they occur because, in a particular instance, the learner is unable to perform what he or she knows.Following Ellis (1997), it needs to check whether the unacceptable forms made by the students were errors or mistakes by giving them the second and third tests.In the second and third writing tasks, attention was paid to the students who previously made unacceptable forms in their first essays (the 70 students).Having been identified, the result of the second and third tests proved that 30 out of 70 students made consistently and systematically unacceptable forms (errors).To support the data analysis, ten out of 30 students who committed grammatical errors were interviewed.Next, the grammatical errors made by the students in their essays were classified into some grammatical types, and interpreted to find the possible causes of the errors.The design was chosen to provide a clear framework for collecting, analyzing, discussing, and interpreting data to address the research goals (Creswell and Clark, 2011).

FINDINGS AND DISCUSSION
In this section, the results of grammatical errors made by the students in their essays are presented.Having been identified and selected, the data in the form of grammatical errors found in the 30 essays of the students were classified and calculated (to find the frequencies).It was found 1,007 grammatical errors, which could be classified into 10 grammatical types.Table 1 presents the types, numbers and percentage of the grammatical errors committed by the participants in their written works (essays).Table 1 shows that the total number of grammatical errors made by the 30 students in their essays was 1,007 errors.The grammatical errors were distributed in ten grammatical types, and the frequencies ranges from plural form, the most frequently occur, and double negation, the least frequency.
In the discussion, it is only selected the types of errors which have the occurrence higher than one hundred times (or more than 10%).They are errors in plural form (188 or 18.7%), in subject-verb agreement (170 or 16.9%), in verb tense (145 or 14.4%), in word form (128 or 12.7%), subject/verb omission (111 or 11.1%), and passive voice (102 or 10.20%).Each of the six findings was presented and discussed below respectively.First of all, the data extracts (if possible accompanied by the Indonesian versions as the source of the errors, written in brackets) are presented on the left columns, while the corrections appear on the right column.Asterisk (*) indicates an error sentence, bold shows the grammatical element of the errors and their correction, and the symbol ^ refers to a missing element in the sentence.

A. Error in Plural Form
The mostly prominent errors made by the students in their essays are errors in using the correct plural form of nouns.Out of 188 errors in plural form, they deleted the plural noun markers '-s/-es' in their essays.The italic elements show the key words which require plural forms in English.(Mereka mengunjungi kedua mahasiswa itu).
They visited both students.
2. *She enjoys food from many different country.
3. *You have a number of choice that you can take.(Anda mempunya sejumlah pilihan yang dapat anda lakukan) You have a number of choices that you can take.
Table 2 demonstrates errors in plural form made by the students.English distinguishes two different forms of (countable) nouns: singular vs. plural forms.Unlike English, Indonesian does not have a marker for the plural nouns, both have the same form.Whether the meaning of a noun is singular or plural is determined by the key words (e.g.kedua 'both', banyak 'many', and sejumlah 'a number of').In contrast, such key words require plural nouns in English.The students have had such habit in their native language which they transfer to L2 (negative transfer).
According to Ellis (1997) two languages having distinct linguistic structures may result in a high frequency of errors in the target language which in turn indicates an interference of L1 on L2.In a short, the course of this error belongs to interlingual transfer.

B. Error in Subject-Verb Agreement
The second mostly frequent grammatical error for the students in this study is related to subject-verb agreement.Rule for subject-verb agreements in English is really simple.A third person singular subject requires base form + the suffix: -s or -es, whereas other subjects do not.As Indonesian does not apply such rule, the students often neglect the agreement between a subject and its verb form in their English essays, as demonstrated in Table 3.Every man and woman is eligible to vote.
As presented in Table 3, singular subjects take plural verbs, data (4), (5), and (6), whereas the plural subjects take singular verbs, data (7) and (8).There are two possible explanations why such errors happen.Firstly, as applies to error in plural form, English and Indonesian differ in the relation between subject features and their verb forms (agreement).In English, a verb must agree with its subject number (singular vs. plural) which is called subject-verb agreement (Phillips, 2001, p. 248).In contrast, the number or status of the subject in Indonesian like in many other Proto-Malay-Polynesian languages does not affect the verb structure.Indonesian does not have a subject-verb agreement rule, so the students have had a habit of ignoring such a grammatical rule in Indonesian.Then, they transferred this habit (L1) into (L2) when they were writing essays in English.In short, the source of the error results from an (negative) interlingual transfer.
Secondly, for the other students, they may know subject-verb agreement rules; however, they still made some errors in their writing essays because they have some problems to identify whether the subjects are singular or plural.The problems particularly appear if the subjects are in the form of complex structures (long noun phrases), e.g. the noun is followed by a prepositional phrase (data 5, and 6), preceded by an expression of quantity 'all of' (data 7), or preceded by a certain word, such as 'every' or 'each' (data 8).As the students had problem to identify the number of subject, consequently they made errors in subject-verb agreement; singular subjects take plural verbs, whereas plural subjects take singular verbs.The source of this error, in fact, is not caused by the native lingual interference (interlingual transfer), rather than it is from intralingual (L2) feature (intralingual transfer).

C. Error in Word Form
This type of error may include the incorrect use of adjective, noun, and verb forms.In their essays, it was found some errors in relation to the use of adjective and adverb forms, and noun and verb forms.Table 4 presents this type of errors.The success of our study does not depend on the length of our study … Table 4 demonstrates the type of errors committed by the learners in learning English which dealt with the use of adjective and adverb forms.Morphologically, adjective and adverb have different forms in English, but their forms remain the same in Indonesian.The only clue (if needed) to the distinguish between an adjective form from its adverb counterpart in Indonesian is an adjective commonly preceded by the word 'yang', while the adverb form accompanied by the word 'dengan', as in: yang baik 'good' vs. dengan baik 'well'.In the writing practice, as shown in Table 4, the students did not pay attention to such word-class changes.They used the adjective forms instead of the adverb ones, data (9), and (10).In contrast, they used the adverb forms instead of the adjective ones, data (10), and ( 11).The students were not aware of the differences between adjectives and adverbs since Indonesian adjectives and adverbs have the same forms.This proves the fact that the students transferred their habit in the native language (L1) into the target language (L2), and the source of error can be called interference or interlingual transfer.
In addition to L1 interference, it also appears an intralingual transfer as the source of error in using adjective, adverb, and noun forms.For some students, they know how to use adjective and adverb, but they generalized that every adverb form is always derived from an adjective plus the suffix -ly, as in the word loud vs. loudly.By this analogy, they thought that hard was an adjective (only), so they generalized the adverb form of hard was hardly, data (13).Another error occurs in the use of an adjective form instead of a noun form ( 14).The use of the adjective 'successful' and 'long' in this sentence is incorrect because both function as the head words of the phrases.Thus, they should be changed into the noun forms 'success' and 'length' respectively.Against, this occurrence of this error is not the result of the native language (L1) interference, but it results from the features of the target language (L2) or it belongs to intralingual transfer.

D. Error in Passive Voice
The next grammatical error deals with the active-passive constructions.Indonesian uses passive sentences more frequently and has more passive construction forms than English does.The Indonesian passive form is particularly marked by the pronoun-verb, ter-verb, and di-verb while the main English passive construction is subject + be + V-3.Accordingly, there is a tendency for the students to use passive sentences when writing essays in English.

Table 5: Common Problems with Active-Passive Constructions
No. Data Extracts (Indonesian) The Correction 15. *The books must be brought by us.
*Is my book borrowed by you? (Apakah bukuku masih anda pinjam?)Do you still have my book?
I will submit the report tomorrow morning.18. *Siti's finger was cut when she skinned a mango.
Siti cut her finger when she skinned a mango.The problem is hard to solve.
Andi kicked the ball strongly.
As presented in Table 5, the passive constructions in Indonesian are indicated by pronoun-verb forms such as kita bawa, anda pinjam, and saya serahkan (data 15, 16, and 17), by ter-verb forms such as teriris (18) and terjadi (19), anSd by di-verb form such as dipecahkan and ditendang (20 and 21).A passive construction in English is commonly used when the agent of the activity is not explicitly identified.This is called the agentless passive form (Finegan et. al, 1992 pp. 190-191).Consequently, the Indonesian passive construction cannot automatically be transferred into passive sentences in English.Since all the agents in the sentences (data extracts) above are clearly identified, they should be expressed in active constructions rather than in the passive ones (in English).Such errors may happen since they are strongly influenced by their native language habit.Both Indonesian and English have passive sentence constructions, but the use of the passive voices can differ from one language to another.As Djatmika et al. ( 2014) stated that the difference on the grammatical systems cause some students make grammatical errors in writing English.Therefore, the students have to initially comprehend the linguistic knowledge of L2, so that they will be able to produce L2 text in a natural way.

E. Error in Subject/Verb Omission
The next prominent error found in the student essay writing is the omission of subject or verb, or both from the construction of English sentences.The finding of this research shows that there are 111 errors found in the students' essays.The errors cover the absence of subject from the sentence construction or replacing the subject with an object of preposition, the omission of a finite verb from a sentence, as well as the deletion of both subject and finite verbs from a sentence, as demonstrated in Table 6.He is very good at Mathematics.
As demonstrated in Table 6, the students omitted the subject and finite verb, data (22), and replaced the subject with an object of preposition, data (23).In the next sentences, data (24 -28), the students committed grammatical errors because they omitted finite verbs from their sentences, as shown by the symbol ^.The Indonesian version of ( 22) is well accepted in Indonesian because the subject of the first clause can be controlled by the subject of the main clause, and the word mandi 'bath' can function as a verb.The next sentences in which the finite verbs are missing are also accepted in Indonesian because this language does not have the verb form distinctions (e.g.finite vs. non-finite verbs).Unlike English, Indonesian can have the verb ditulis 'written' as a full (finite) verb which makes the sentence ( 24) is wellform by itself, and (similarly) an interrogative sentence (25) does not need an auxiliary verb.In contrast, the (non-finite) verb 'written' cannot be the predicate of the subordinate clause without the (finite) verb 'was' (24).The only possibility for this construction without a finite verb is to change the (adjective) clause into a reduced form by deleting the connector 'which' as shown in the correction.Next, Indonesian sentences can have adverbial predicate (27), or adjectival predicate (28) while an English sentence always needs a finite verb as a predicate element (a verbal predicate).All examples give the idea that they committed the errors because they were strongly influenced by Indonesian in learning English as a foreign language.From the discussion above, it can be said that learners usually transfer the L1 rules to the L2 ones.Some omissions of subject, to be, and auxiliary verbs were used by the L2 learners result from their habit in their native language (interlingual transfer).

F. Errors in Verb Tense
Tense is a frequent category in the languages in the world, but it is far from universal (Trask, 1993, pp. 276).Like many languages in Asia, Indonesian is an example of a language which lacks tense entirely.Indonesian verbs do not correlate with the distinctions of time.Whether the time is past or non-past, the verb remains the same.In contrast, English exhibits a tense system.Naturally, the Indonesian-English learners often made errors in choosing the right tense, and the right forms of verbs, as presented in Table 7.If I were a bird, I would fly all over the world.
As reported in Table 7, the students made errors because they transferred the habit of their L1 rule to L2 in which the verb forms ('see', 'enjoy', and 'is') do not correlate with the (past tense) time markers (e.g.'yesterday' and 'last holidays') in data ( 29) and (30).Next, as shown by data (31), the learners mixed both the result of an activity and the specific time into one sentence.Unlike Indonesian, English only chooses one of them (perfect tense or simple past tense, but not both) (Murphy, 1994, pp. 14).If the result of the activity is the focus of the utterance, the present perfect tense should be used.Alternatively, if the speaker identifies a specific point of time, he should choose the simple past tense.In other words, we cannot combine both the result and the particular time referring to the activity into one sentence.In short, the learners made such error because Indonesian does not have tense system, so they transferred the habit of their native language (L1) into L2.Finally, the students also made error in term of 'condition' which is expressed through the wrong verb forms/tenses (data 32), which should be 'were' and 'would fly'.As the beginners, they are not familiar yet with the construction of expressing a 'conditional' sentence realized through the verb forms.Accordingly, the acquisition of tense will be very difficult for the learners since there are quite big difference rules between the two languages.

CONCLUSION
Based on the identified and classified errors found in 30 essays produced by the 30 first year students of the writing classes of the English Department, Faculty of Letters, Jember University, Indonesia, it was found 1,007 grammatical errors.The errors committed by the students could be classified into ten types, and the six mostly prominent errors are errors in Celt, Volume 16, Number 1, July 2016, pp. 1-21 plural form, subject-verb agreement, verb tense, word form, subject/verb omission, passive voice, article, preposition, pronoun, and double negation.
From the discussion, it can be concluded that the students made errors in the grammatical patterns because they are strongly influenced by Indonesian (L1) patterns that they acquired before, even the rules have become a well-rooted habit in their minds.The L1 patterns were reflected in their essays which can be depicted through errors in plural form, passive voice construction, subject/verb omission, and verb tense.Such errors were strongly caused by the interference of L1 (interlingual transfer) because they do not have such grammatical features in L1 that are very important in L2.
In addition to interlingual transfer, the grammatical errors were also caused by the student's inability of applying L2 rules comprehensively.They made errors because they made overgeneralizations of L2 rules.Such errors occur in subject-verb agreement and in word form.Therefore, the grammatical errors are not all of them from their mother tongue interference, but also from their intralingual transfer of the target language.It is right that grammatical errors are both from the interference of mother tongue (interlingual transfer) and from the mutual interference of items in the target language (intralingual transfer), however, in case of Indonesian speakers, interlingual transfer plays greater causes than intralingual transfer since L1 and L2 are from different language families which make possible to have distinct linguistic principles.
The result of this analysis can be advantageous for learners, teachers, and course designers.Considering the sources of the errors they made, it is expected that students will be able to analyze and correct their own errors which will improve their English more accurately.This research is also hoped to provide teachers and course designers with better understanding of the sources of the students' errors, which motivate them to evaluate the teaching approaches applied so far, and to find the more appropriate ones to deal with the foreign language learners' errors.
