CHAPTER III METHODS OF INVESTIGATION
Chapter three provides the methods of investigation. I divide this chapter into six parts, they are: approach of the study, subjects of the study, role of the researcher,
the data of research, procedure of data collection, and procedure data analysis. Those parts are described as follow:
3.1 Approach of the Study
The purpose of this study is to find out to what extent the text-types materials in When English Rings A Bell and Bright English textbooks for grade 8 are
appropriate with the Basic Competences 3.10, 3.12, and 3.14 in the Curriculum 2013. The Basic Competence 3.10, 3.12, and 3.14 are respectively about
descriptive materials, recount materials and narrative materials. This study also has purpose to compare the elements of lexico-grammatical features of reading
texts in the text-types materials in both English textbooks. In presenting the data, I used qualitative research approach. Qualitative
research can be done in some models, like case studies, biographies, phenomenologies, text analyses, ethnographies, etc Muhammad, 2011:30.
Qualitative research is a research that produces analysis procedure which does not use statistical analysis procedure or other quantification methods Moleong,
2005:6. The design of this study is exploratory-interpretive one which utilises a
non-experimental methods, yields qualitative data, and provides an interpretive analysis Grotjahn 1987:59-60 in Nunan 1992:6.
Since this study compares the lexico-grammatical features of reading texts in text-types materials in the two English textbooks, so this study is a comparative
research. The two conventional types of comparative analysis focus on the explanation of differences, and the explanation of similarities Pickvance,
2005:2. It means that I explained the differences and similarities of the lexico- grammatical features of reading texts in the text-types materials in When English
Rings A Bell and Bright English textbooks for grade 8. This study also analyses the appropriateness of text-types materials in those two textbooks based on the
Curriculum 2013.
3.2 Subjects of the Study
The subjects of this study are reading texts in the text-types materials in English textbooks When English Rings A Bell English textbook, published by Indonesian
Ministry of Culture and Education, and Bright English textbook, published by Erlangga. Both English textbooks are for grade 8 and composed based on the
