PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK (LKPD) BERBASIS LITERASI SAINS UNTUK MELATIHKAN KETERAMPILAN ARGUMENTASI PESERTA DIDIK PADA MATERI FAKTOR-FAKTOR YANG MEMPENGARUHI LAJU REAKSI

DEVELOPMENT OF STUDENT WORK SHEET BASED ON SCIENCE LITERACY TO TRAIN STUDENT’S ARGUMENTATION SKILLS ON FACTORS THAT EFFECT THE RATE OF REACTION MATERIAL

Penelitian ini bertujuan untuk mengembangkan Lembar Kerja Peserta Didik (LKPD) berbasis literasi sains untuk melatihkan keterampilan argumentasi peserta didik pada materi faktor-faktor yang mempengaruhi laju reaksi. LKPD ini disusun berdasarkan domain literasi sains menurut PISA yaitu domain pengetahuan, domain konteks, domain kompetensi ilmiah, dan domain sikap. Keterampilan argumentasi dilatihkan berdasarkan pada indikator keterampulan argumentasi menurut Toulmin meliputi claim, data, warrant, backing, qualifier, dan rebuttal. Metode penelitian yang digunakan yaitu Research and Development (R&D) dengan model Borg and Gall. Penelitian ini menghasilkan LKPD yang layak ditinjau dari validitas, kepraktisan, dan keefektifan.Validitas LKPD dinyatakan sangat valid ditinjau dari aspek isi dan konstruk dengan persentase masing-masing adalah 88% dan 89%. Kepraktisan LKPD dinyatakan sangat praktis ditinjau dari respon peserta didik yang mendapatkan persentase sebesar 94,1% didukung dengan aktivitas peserta didik dengan persentase 90% dalam kategori sangat praktis. Keefektifan LKPD dinyatakan sangat efektif ditinjau dari tes literasi sains dengan skor N-Gain 0,7 kategori tinggi dan tes argumentasi dengan skor N-Gain 0,8 kategori tinggi. Didukung dengan uji Wilcoxon dengan penerimaan H1 yang menunjukkan adanya perbedaan rata-rata pada literasi sains maupun argumentasi sebelum dan sesudah perlakuan, uji korelasi Spearman mendapat rho sebesar 0,843 yang menandakan adanya hubungan kuat antara literasi dan argumentasi, serta ketuntasan belajar  sebesar 88%.

This study aims to develop Student Worksheets based on scientific literacy to train students' argumentation skills on factors that effect the rate of reaction material. This student worksheet is compiled based on the scientific literacy domain according to PISA, domain of knowledge, domain of context, domain of competence, and domain of science attitude. Argumentation skills are trained based on indicators of argumentation skills according to Toulmin including claims, data, warrants, backing, qualifiers, and rebuttals. Research and Development (R&D) method with the Borg and Gall model. This research resulted in the feasibility of student worksheet in terms of validity, practicality, and effectiveness. The validity of student worksheet was stated to be very valid in terms of content and construct aspects with the respective percentages being 88% and 89%. The practicality of student worksheet was stated to be very practical in terms of the responses of students who got a percentage of 94,1% supported by student activities with a percentage of 90% in the very practical category. The effectiveness of student worksheet was stated to be very effective in terms of the scientific literacy test with an N-Gain score of 0.7 in the high category and an argumentation test with an N-Gain score of 0.8 in the high category. Supported by the Wilcoxon statistical test with acceptance of H1 which shows an average difference in scientific literacy and argumentation before and after treatment, the correlation Spearman test had rho score of 0,843 shows a strong relationship between literacy and argumentation, as well as 88% learning completeness.
