Research Design RESEARCH METHODOLOGY

The first step, the writer collected the data by doing classroom observation, giving questioner to the students and also giving tests to the second grade students of SMP YPN Bojong Gede about regular and irregular verbs in the simple past tense. Next, after collected the data, the writer identified the data which she got from the observation, tests and questioner. She also determinate the sample of the learners which were deviated from the target language by giving a circle to the incorrect answer to the student’s answer. Then, the writer classified the errors based on the surface strategy taxonomy according to James. They are omission, addition, misformationmisselection, misordering and blends. She also classified the errors into several tables according to types of errors. After classifying the errors based on the surface strategy taxonomy, the writer made a percentage of the errors from the students answer. It will be describe as the formula below: P = Percentage F = frequency of wrong answer N = Number of sample In the explanation of errors, the writer tried to analyze the sources of error after making a percentage of students’ error and giving questioner to the students. In this part, the writer used the source of error by Hubbard et al. that consists of mother-tongue interference, overgeneralization, and errors encouraged by teaching material or method. In the last step the writer evaluated the effects of errors which made by second grade students of SMP YPN Bojong Gede in mastering regular and irregular verbs in the simple past form. Then, the writer classified the effects into two kinds, global and local error. Finally, to sum up the result, she gives some conclusions. 34

CHAPTER IV RESEARCH FINDINGS

A. Data Description

Having done class observation see appendix 1a, the writer gave the tests to the second grade students of SMP YPN Bojong Gede. The writer gave the tests which covered by Regular and Irregular Verbs areas that consist of 30 questions. Then, the writer analyzed the students’ errors in mastering Regular and Irregular Verbs by classifying the students’ error. After that, the writer makes a percentage of the types of errors. In addition, the writer also gave questioner to the students to find the source of error see appendix 2a 2b.

1. The Result of Observation

According to Patricia A. Duff, observation can help researcher understand many aspects, such as the socialcultural, linguistic contexts in which the language is used and also collect relevant linguistic and interactional data. 1 In this study the writer did the observation as the supporting data in order to get the sources of error The writer did the class observation by observing the students and teacher activity in teaching-learning process in the classroom. It was held at second grade students of SMP YPN Bojong Gede which consist of 25 students. This observation was conducted on 6 th of December 2012 at 07.30 – 09.00 a.m. In this observation, the writer was as an observer which did not involve in teaching learning process. 1 Patricia A.
