THE RELEVANCE OF LEARNING MATERIALS OF THE ENGLISH TEXTBOOK “LOOK AHEAD” FOR THE TENTH YEAR STUDENTS WITH THE INSTITUTIONAL LEVEL ENGLISH CURRICULUM FOR GRADE X
Abstract
Curriculum is an important tool for successful teaching. It functions as the 
basis for delivering the teaching and learning materials in the classroom. Dealing with 
curriculum, a textbook plays a crucial role in delivering the curriculum materials. It 
provides a  base of materials for both teachers and students. However, it is not a 
perfect teaching tool because it may have incomplete and irrelevant materials. So, it is 
recommended that it has to be analyzed comprehensively before it is selected and 
used in the classroom. This research focused on analyzing the relevance of learning 
materials in an English textbook with the Institutional Level English Curriculum 
because it is important to know whether the learning materials of the English 
textbook are relevant or not  with the curriculum applied and therefore it can be 
informed that the textbook analyzed is suitable or not to be used in the classroom. 
  This research was conducted to analyze the relevance of learning materials of 
the English textbook “Look Ahead” for the tenth year students published by Erlangga 
in 2007 with the Institutional Level English Curriculum for grade X. The design of 
this research was descriptive quantitative and qualitative research. The data of this 
research were the learning materials of the  English textbook “Look Ahead” for the 
tenth year students published by Erlangga in 2007. The Institutional Level English 
Curriculum for grade X was the parameter to measure the relevance of the learning 
materials of the English textbook “Look Ahead” for the tenth year students published 
by Erlangga in 2007. It was found that the learning materials in the English textbook “Look Ahead” 
for the tenth year students published by Erlangga in 2007 are 31% relevant and 69% 
irrelevant to the Institutional Level English Curriculum for grade X. It happens 
because the English textbook “Look Ahead” does not include some learning materials 
stated in the Institutional Level English Curriculum for grade X, it has many other 
learning materials which are not stated in the Institutional Level English Curriculum 
for grade X, and its learning materials are not put in order as suggested in the 
Institutional Level English Curriculum for grade X.  Nevertheless, this textbook still 
can be a source of learning materials because it still has 31% of relevant learning 
materials and it has cultural awareness section which is important to give some input 
to the students about cross-cultural understanding. 
Based on the research result the researcher suggests the English teachers who 
use the English textbook “Look Ahead”  to  have another supplementary textbook as 
the supporting source of this textbook.  In other words, the English teachers are 
suggested to use more  than one textbook. Besides, they are suggested to make their 
own textbooks based on the Institutional Level English Curriculum for grade X. It is 
also suggested that the future researchers undertake a further research that focuses on 
the relevance of the other English textbooks published by the other publishers with 
curriculum as the topic of investigation.
