Pendidikan BSNP aspects. The readability level of the textbook measured using Cloze Test, and the textbook effectiveness measured using pretest and posttest with pretest-posttest
control group design as the research design. Experimental group in this study is VIIF Class, and control group is VIIH Class. The experimental group uses developed science textbook and
the control group uses Ilmu Pengetahuan Alam book for VII grade that published by Departemen Pendidikan Nasional in 2013.
3. Results and discussion
Results of this study includes product characteristics, product feasibility, product readability, and product effectiveness. Textbook characteristics are contain all of four
scientific literacy aspects and has a balance proportion of scientific literacy aspects. Four scientific literacy aspects presented on main part in textbook, they are Ayo Belajar Science
as the body of knowledge, Mencoba Yuk Science as the investigative nature, Ayo Berpikir Ilmiah Science as a way of thinking, and Sains dalam Kehidupan Interaction of Science,
Technology and Society. The balance proportion showed on the percentage indicators for each aspects. The first aspects Science as a way of thinking has 40 number of all indicators,
and the other aspects has 20 for each.

Very Feasible
Feasibility test result was shown on Table 1. From the data, the average feasibility result got percentage 81.25, it means the developed science textbook classified as a very
feasible learning source. The result showed that the textbook as the product was well developed. The developing process was pointed from Panduan Pengembangan Bahan Ajar
that published by National Education Department in 2008. One of the important point for textbook developing according to National Education Department 2008 is the material must
be derived from competences that will be achieved. Those competences were shown as the indicators or learning objectives.
Data of the readability test was shown in Figure 1. Readability test result showed positive score that got percentage average 57 that is 80.05. It means the developed
textbook was easy to read and to learn. Some of the result has lower percentage than 57, it means there was some correspondent that having difficulty to learn the developed science
textbook. One of those difficulties is their lack of vocabulary.
Based on effectiveness test result, the developed science textbook classified as an effective stimulant to increase students’ scientific literacy. It’s showed on the score gain of
experimental group that higher than the control group’s score gain. The average score gain of experimental group is 0, 37 which classified as middle category and score gain of control
group is 0, 18 which classified as low category. The result of score gain from each scientific literacy aspects were shown on Figure 1.

Figure 1. Graph of readability test result.
Figure 2. Score gain graph of scientific literacy aspects.
Graph showed that the gain of each scientific literacy aspects in experimental group has a smooth distribution, but the control group’s not. Based on Statistic Test of both group,
the result showed that statistically the scientific literacy of experimental group higher than the control group’s one. The gain of Science as the knowledge’s body aspects in both group
has the highest gain, it means that student’s ability on recalling information of both group is high. It caused by the biggest part of the both science textbook that been used is science as
the body knowledge aspect. And for the other aspects of scientific literacy, experimental group has higher score. In average the experimental group score are high, but the proportion
are not 2: 1: 1:1 like the proportion of the developed science textbook. It can be caused by some factors. But the factors are not been studied yet.
The effectiveness of developed science textbook supported by the quality of the text. The high score of developed science textbook readability test show the quality of the text.
According to the Devetak Vogrinc 2013’s study result that the quality of a science textbook was on the sentences quality which sentences were the most content in the
textbook. Another factor that support the effectiveness of developed science textbook is the learning strategy that used in the learning process. The learning strategies that used in
experimental group and control group were same. In this study, the learning study that used was Integrated Reading and Concept Mapping. It is chosen because the learning strategy

which start with reading and integrated with scientific literacy textbook using would a positive effect on student’s learning result. It was appropriate with a study result of Taslidere
Eryilmaz 2010 that an integration of reading and scientific literacy textbook using was more effective to increase student’s learning result than other learning strategy.
The difference treatment of experimental and control group was only on the learning source. The science textbook that used in control group was Ilmu Pengetahuan Alam for VII
Grade that published by National Education Department while the experimental group used developed science textbook based on scientific literacy aspects. This study was focus on a
complete and balance of scientific literacy aspects on science textbook, textbook feasibility, textbook readability and textbook effectiveness. The integrated science principle refer to
Connected model. The integration science of the textbook has not been studied.
