CHAPTER V CONCLUSIONS AND SUGGESTIONS
This chapter presents the conclusions and some suggestions of the research. The purposes are to give brief and clear description about the result of the research
and to give some suggestions. The suggestions of this research are aimed to Biology teachers and the future researchers as well.
A. Conclusions
Based on the analysis result, the researcher discovered that the Biology teacher has used classroom language functions in English. Meanwhile, the amount of
using English classroom language functions was not as much as Indonesian. After analyzing the problems faced by the biology teacher in applying classroom language
functions, the researcher classified them into three categories based on the cause of the problems. The first category was the problem caused by the teacher’s habit, the
second one was the problem caused by the limited English proficiency which was possessed by the teacher, and the third one was that the limited of time to learn
English. The first category was the problems faced by the biology teacher in grade
tenth in applying classroom language functions caused by the teacher’s habit to always use Indonesian. The problems were 1 the teacher had a habit to use Arabic
61 words to open the meeting and 2 the teacher had a habit to use Arabic words to
close the meeting. The second category was that the problems faced by the limited English
proficiency had by the Biology teacher of tenth grade. Those problems were 1 the teacher did not know how to instruct students by using English expressions
spontaneously 2 the teacher did not know what question to be used to elicit students’ opinion in English 3 the teacher did not know how to construct a good
sentence with an appropriate grammar to convey a new meaning in English 4 the difficulty in narrating a particular event using English with an appropriate sentence
structure 5 the teacher did not know how to give a clue to help students to remind a particular learning materials 6 the teacher had a difficulty in constructing a correct
sentence by using English to explain a certain learning materials 6 The teacher still makes some mistakes in using a correct question in English to measure the students
understanding 7 The teacher feels that she was not affluent to correct students mistake in English 8 the teacher had a limited of utterance to commend on students’
performance 9 the teacher had a difficulty in memorizing any kind of new words. The third category was that the problem caused by the lack of time which was
needed by the Biology teacher to learn English. The teacher had a limited of time to learn English because she, as a teacher, has so many businesses to do. This factor,
then, became an obstacle since she could not be able to improve her knowledgeabout English.
