Acid-base is one of topics considered difficult by students. This concept is broad,  varied. Despite it is very closely related to everyday life, its application was still lacking. The development of teaching materials in the form of a module was deemed to be a solution to this problem. The aim of this research was to develop CTL module with green chemistry orientation in acid-base subject material to improve science literacy of students. This study was developed ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The developed product was validated by three experts, a practitioner and ten high school students. Data were analyzed using percentage formula. Qualitative data in the form of comments and suggestions from validator were used as consideration to revise the developed module.Tthe effectivity of the module was assessed using N-gain test. Based on validation results, we obtained average of 86,5%, 97%, 88%, and 94,58%. Effectivity evaluation using N-gain test shows an average score of 0,5 with moderate category. Result of student attitudes towards science data has an average score of 74% with good qualifications. It was concluded that developed module prototype is effective for acid-base topic, and most likely for other topics in learning process and growing student science literacy.

Penelitian ini bertujuan menghasilkan LKPD berwawasan green chemistry untuk meningkatkan kemampuan literasi sains peserta didik pada materi larutan elektrolit dan non elektrolit yang layak. Prinsip-prinsip green chemistry yang dikaji dalam penelitian ini terbatas pada prinsip green chemistry no 1, 7, dan 12. Metode penelitian pengembangan menggunakan model 4-P (pendefinisian, perancangan, pengembangan, dan penyebaran) dan dibatasi hanya sampai tahap pengembangan. Uji coba terbatas dilakukan kepada 12 peserta didik di kelas X IPA 6 SMA. Pengembangan LKPD dinyatakan layak apabila memenuhi tiga aspek, meliputi aspek validitas, kepraktisan, dan keefektifan. Dikatakan valid, praktis, dan efektif jika didapatkan hasil persentase ≥61%. Hasil pengembangan LKPD disimpulkan bahwa kelayakan LKPD pada aspek validitas terdiri dari dua hal, yaitu validitas isi yang memperoleh persentase 79,75% yang berada pada kriteria valid dan validitas konstruk mendapatkan persentase 82,84% dengan kriteria sangat valid. Kepraktisan LKPD ditinjau dari observasi aktivitas dan angket respon peserta didik yang masing-masing memperoleh hasil praktis sekali dengan rata-rata persentase sebesar 93,05% dan 94,79%. Aspek keefekifan ditinjau dari hasil tes kemampuan literasi sains yang memperoleh nilai N-Gain sebanyak 0,84 yang berada di kategori tinggi, sehingga LKPD yang dikembangkan dinyatakan layak untuk digunakan dalam proses belajar mengajar.Kata kunci: Lembar kerja peserta didik, Literasi Sains, dan Green Chemistry. AbstractThe aims of the research to produce feasible student worksheet with green chemistry insight to increase science literacy ability of student in matter of electrolyte and non electrolyte solution. The green chemistry principles that studied in this research were limited to principle number 1, 7, and 12. This research method was used development research design of 4-P (define, design, develop, and desseminate) and only limited on develop stage. Limited test was conducted to 12 students in the class X IPA 6 SMA.. The results of the developed student worksheet concluded that the feasibility of student worksheet if it meets two aspects, namely validity, practicality, and effectiveness aspects. Said to be valid, practical, and effective if the percentage results are obtained ≥61%. Feasibility student worksheet in the validity aspect consists of two things are content validity obtain percentage of 79,75% which is in the valid criteria, and construct validity get percentage of 82,84% with very valid criteria. Practicality of student worksheet in terms from observation of student activities and student response questionnaire obtained very practical results with a percentage of 93,05% and 94,79%. Effectiveness aspect in terms from the results of improving science literacy ability indicated by N-gain score of 0.84 which is in the high category, thus the developed of student worksheet is stated feasible for be used in teaching and learning process.Key words: Student Worksheet, Science Literacy, and Green Chemistry.

Science literacy is a major goal of science educational reform (NRC, 1996; AAAS, 1998; NCLB Act, 2001). Some believe that teaching science only requires pedagogical content knowledge (PCK) (Shulman, 1987). Others believe doing science requires knowledge of the methodologies of scientific inquiry (NRC, 1996). With these two mindsets, the challenge for science educators is to create models that bring the two together. The common ground between those who teach science and those who do science is science communication, an interactive process that galvanizes dialogue among scientists, teachers, and learners in a rich ambience of mutual respect and a common, inclusive language of discourse (Stocklmayer, 2001). The dialogue between science and non-science is reflected in the polarization that separates those who do science and those who teach science, especially as it plays out everyday in the science classroom. You may be thinking, why is this important? It is vital because, although not all science learners become scientists, all K-12 students are expected to acquire science literacy, especially with the implementation of the No Child Left Behind Act of 2001 (NCLB). Students are expected to acquire the ability to follow the discourse of science as well as connect the world of science to the context of their everyday life if they plan on moving to the next grade level, and in some states, to graduate from high school. This paper posits that science communication is highly effective in providing the missing link for K-12 students’ cognition in science and their attainment of science literacy. This paper will focus on the “Science For Our Schools” (SFOS) model implemented at California State University, Los Angeles (CSULA) as a project of the National Science Foundation’s GK-12 program, (NSF 2001) which has been a huge success in bridging the gap between those who “know” science and those who “teach” science. The SFOS model makes clear the distinctions that identify science, science communication, science education, and science literacy in the midst of science learning by bringing together graduate student scientists and science teachers to engage students in the two world’s dialogue in the midst of the school science classroom. The graduate student scientists and the science teachers worked as a team throughout the school year and became effective science communicators as they narrowed the gulf between the two worlds.
