CHAPTER IV RESULTS AND DISCUSSION
This chapter covers the answer and discussion of the research problem that has been mentioned previously in Chapter I. In this chapter, the data that have
been gathered through the checklist will be presented and analysed. This chapter consists of two parts. The first part is presentation of the results of textbook
evaluation and the second part is description of the strengths and weaknesses of the textbook.
A. Textbook Evaluation
This was collaborative research which was aimed to analyse the content of Interlanguage: English for Senior High School Students XI for Science and Social
Study Programme written by Joko Priyana, Riandi and Anita Prasetyo Mumpuni. This textbook was evaluated by using a checklist that was adapted from
Cunningsworth’s 1995 textbook evaluation checklist. The evaluation of the textbook covered the evaluation of the eight aspects in the checklist. They were
aims and approaches, design and organization, language content, skills, topic, methodology, teachers’ books, and practical considerations. This checklist totally
covered fifty four criteria to be evaluated. The total of the criteria fulfilment was counted and presented in a percentage. Since this research was collaborative
research, other collaborators’ responsibilities were to validate the results of this research. Therefore, the presented results had been read and crosschecked by the
51 other collaborators. The results of the evaluation of the each aspect as well as the
overall evaluation of the textbook in a percentage were presented in Table 4.1.

achieved in language content aspect. Then, it was followed by methodology aspect which achieved 80 of criteria fulfilment.
Other four aspects were considered fair fulfilment as the percentages were between 60 to 79. Those aspects were aims and approaches, skills, topic, and
practical considerations. Then, one out of eight aspects attained sufficient fulfilment since the percentage was 57.14. This sufficient fulfilment was
