Development of Science Textbook Based on Scientific Literacy for Secondary School

Abstract

The purpose of this research is to develop scientific literacy-based science text books and to determine the characteristics, validity, readability, as well as the effectiveness of the textbooks.The study started with product development and then continued by feasibility test and readability test. Feasibility test was done with the respondent of lecturer and science teachers of VII, VIII, IX grade at SMP N at Central Java. Readability test used cloze test that filled by VII, VIII, and IX grade students at that schools. The data analysis was done with percentage discription and t-test. The study results in feasibility test showed that the developed literacy science textbook has average score 90,74%. It means the literacy science textbook is suitable. Based on the readability test result, science literacy textbook is easy to learn. The average of score of cloze test was 88,14%. The effectiveness of the developed science textbook was classified as an effective stimulant to increase students' scientific literacy. ABSTRAKTujuan penelitian ini adalah mengembangkan buku ajar IPA berbasis literasi sains, menentukan karakteristik, kevalidannya, tingkat keterbacaan, dan keefektifannya. Penelitian pengembangan ini dimulai dengan analisis kebutuhan, penyusunan tema, pengembangan buku ajar, uji kevalidan dan keterbacaan buku yang telah dikembangkan. Validasi dilakukan oleh dosen dan guru IPA kelas VII, VII, IX. Uji validitas, tingkat keterbacaan dan keefektifan buku dilakukan di SMP N di Jawa Tengah. Subjek ujicoba adalah siswa kelas VII, VIII, IX. Teknik analisis data menggunakan deskriptif persentase untuk uji kevalidan dan keterbacaan, dan uji t untuk keefektifan. Hasil validasi menunjukkan seluruh buku yang dikembangkan adalah valid dengan rata-rata skor 90,74% berada pada kategori sangat valid. Skor rata-rata tingkat keterbacaan sebesar 88,14% beradapada kategori mudah dipahami. Buku ajar yang dikembangkan efektif untuk meningkatkan kemampuan literasi sains.

The development of scientific literacy assessment to measure student’s scientific literacy skills in energy theme

“…The ratio of category of scientific literacy in the developed evaluation instrument was 37,50% : 25% : 18,75% : 18,75%. The results was agree with the ratio of category of scientific literacy 42% : 19% : 19% : 20% [4]. The suitability of science as a body of knowledge is the highest, but inexpediency appeared on the lowest, the category of science as a way of investigating is the lowest, the research explain that the lowest category is science as a way of thinking and interaction among science, technology and society.…”

“…Scientific literacy is important to knew by students in order to students' way to know the environment, health, economy, and other problems which are meet by modern society that's very depend on progress of technology and developed science knowledge [3]. Scientific literacy skills is showed on PISA (Programme for Student International Achievement) which is international study OECD (Organization for Economic Co- [4]. The results is needed on science learning evaluation in class.…”

The Effectiveness of Turtle Mobile Learning Application for Scientific Literacy in Elementary School

“…Assessment of scientific literacy is assessing students' understanding of science content, science processes, and the context of science applications. Assessment of scientific literacy is not only oriented to mastering science material, but also to mastering life skills, thinking skills, and the ability to apply science in "real life" contexts (Rusilowati et al, 2016).…”

“…Science is one of the subjects that occupy an important role in elementary education because science can be an important tool for students facing various challenges in the global era. Scientific literacy is the ability to understand and communicate science, and to apply scientific principles to solve problems (Rusilowati et al, 2016). The Program for International Student Assessment (PISA) found that the scientific literacy of Indonesian students are still below the international average.…”

Class Program Differences in Student's Scientific Literacy

“…The previous study identify that the nine books of science in junior high school, have reflected the scientific literacy, but the proportion of the emergence of scientific literacy categories is not balanced. The category that looks dominant is science knowledge [15].…”
