F. Definition of Terms
Below are the list of the terms that are used in this research and the definitions of the terms:
1. Classroom Language Functions In this study, classroom language functions refer to “the purpose for which
teachers and learners use language in the classroom” Spratt et al., 2005. Harmer 2007 also states that “language function is a purpose that a teacher wishes to
achieve when he says or writes something”. There are some classroom language functions which are often used by teachers, those are: instructing, explaining,
conveying the meaning of new language, narrating, correcting eliciting, prompting, and checking learning. In addition, Davies and Pearse 2000 state that there are still
some other functions of classroom language such as greeting, closing, and giving feedback. Each of those aspects has its own functions. In this study the researcher
will analyze the use of classroom language functions including greeting, instructing, explaining, conveying the meaning of new language, narrating, correcting eliciting,
prompting, checking learning, giving feedback and closing, which are used by the Biology teacher in tenth grade class.

8 natural science concerned with the study of life and living organisms, including their
