ABSTRAK

 

This study was intended to investigate and describe the readability of ‘A-Level Chemistry for Senior High School Volume 1B', an endorsed Chemistry textbook for SBI/RSBI in Malang that uses English as the medium of instruction. The readability tests employed are a cloze test, Fry Readability Graph, Flesch-Kincaid Readability Formula, and Dale-Chall Readability Formula. 

The design of the study was descriptive quantitative research. In conducting the cloze test, a 500 word passage with every-ninth-word deletion and 50 blank items was selected. The study was conducted in SBI/RSBI high schools which employ the textbook in Chemistry instruction, namely SMAN 3 Malang, SMAN 5 Malang, and SMAN 8 Malang. A class of ± 30 students from each school was elected as the result of proportional random sampling used. The instrument try out was conducted in SMAN 4 Malang. In applying the readability formula, 18 passages from the front, middle, and back part of the textbook were selected to be calculated using four readability tools, namely www.readabilityformulas.com, www.read-able.com, www.readability-score.com, and the readability measurement from Microsoft Word.

Having analyzed the data, it was found that the readability level of ‘A-Level Chemistry for Senior High School Volume 1B' according to the result of the cloze test, was in the frustration level for most of the students. According to the result of the readability formula, the textbook is difficult to read and suitable for the reader in Grade 10-12. Inferring to those measurements, ‘A-Level Chemistry for Senior High School Volume 1B' is difficult to read and slightly above the students' reading level, thus resulting in the frustration level of comprehending it.

It is suggested for the Chemistry teacher to anticipate the level of students' readability level and thus may discover some ways to overcome the difficulty to attain the goal of the teaching and learning process, such as giving other reading materials that are suitable for the students or adding more time for reassuring the students' comprehension. For the English teacher, knowing that the students mostly have difficulty in decoding some scientific terms, can enrich students' knowledge of the related vocabulary to assist their comprehension. As for textbook writers, specifically for the ‘A-Level Chemistry for Senior High School Volume 1B' writer, the result of this study is expected to give an illustration of the importance of readability in writing textbook, especially for science. It is recommended for the writers to check the passages' readability so that some necessary adjustment, such as paraphrasing or choosing alternative dictions, can be carried out beforehand. For future researchers, there are a lot of other bilingual and English textbooks for other subjects that are potential to be investigated further. The development of grade level conversion may also be helpful in the study of readability in advance.
