and analyzed the grammatical errors including classifying the errors into the types of errors by target modification taxonomy, Dulay, Burt, and Krashen’s,
and counting the percentage of each error types. 3. Stage 2, identifying the errors by using Dulay’s theory, namely: omission,
addition, misorder, and miselection. And classifying of errors into its grammatical category, namely: Verb tense, Auxiliary Verb, Question word,
and Punctuation. 4. Stage 3, explaining and diagnosing the errors that students made on
transforming affirmative to negative and interrogative sentences of simple present tense by modifications the students’ errors into 4 categories based on
Dulay’s theory, they are: omission, addition, misorder, and miselection. 5. Stage 4, the writer evaluates the errors.
6. Stage 5 is prevention and feedback. The main purpose of error analysis is to plan about the remedial action for the errors.
1. Identifying Types of Errors
To identify the error, the writer focused to the correct grammatical form which divides to negative, interrogative and WH Question sentences of simple
present tense. After analyzing the whole errors committed by the students, the writer
found 4 types of errors. Those are omission, misselection, addition, and misorder. Omission has been detected by the occurrences of the errors which omit
some letters and words. The writer has given symbol for the erroneous words. For instance, some students produced a sentence “
What time she have English class
today
” item number 4. The symbol indicates that something is missing. In other word, the sentence is incomplete. The sentence should be the WH question.
The first should be filled by auxiliary “does”. The second should be filled by the question mark “?”. It should be revised “What time does she have English
class today?.
Misselection is error caused by selecting the wrong words, and not by using the wrong form of words. The writer indicates the errors made by students
by underlining the wrong word. For instance, some students produced a sentence “My mother don’t wash our clothes every day” item number 5. The previous
sentence is a negative sentence. The underlined word is indicating that the students have chosen the wrong word. For pronoun “my mother” should use
auxiliary “doesn’t”. it should be revised “My mother doesn’t wash our clothes every day”.
Addition is the presence of an item that must not appear in well-formed utterance. To indicate this error, the writer has bolded the wrong word. For
instance, some students produced a sentence “When does my mother washes our
clothes?” item number 4. The previous sentence is a WH Question sentence. The bolded word indicates that something is adding. In other word, the sentence is
ungrammatical because the WH Question sentence of simple present, the verb is doesn’t need suffix –es. The sentence should be revised “When does my mother
wash our clothes?”. Misorder is the incorrect placement of a morpheme or group of
morphemes in an utterance. The writer has given symbol to indicate the wrong order of word. For instance, some students produced a sentence “
What doestime she have English class today?”
item number 4. The symbol indicates that the placement of word is incorrect. The sentence should be the WH question. It
should be revised “ What time does she have English class today?.
