This study used the Research and Development method with a 4D design modified into 3D: the definition stage, the design stage, and the development stage. The research subjects were 35 eighth- grade students in junior high school. The instruments used in this study consisted of a multiple-choice test to capture the achievement of the content, students' science competence and knowledge, an attitude scale to capture students' scientific attitudes, and student response questionnaires to the learning web. The results showed that learning science using the learning web could improve scientific literacy skills in the medium category. Based on the results and data analysis, the increase in learning outcomes calculated using the N-Gain Test with an average gain of 55.89% is in the medium criteria, indicating a positive difference between learning outcomes before and after learning activities. The responses from students and teachers to the learning web are generally positive and supportive of its development and use. Keywords: Learning Web, Scientific Literacy, Junior High School Students INTRODUCTION Students' scientific literacy worldwide is measured by several reliable studies, such as PISA (Program for International Student Assessment) and TIMSS (Trends in International Mathematics and Science Study) (Fuadi et al., 2020). PISA is carried out by the OECD (Organization for Economic Co-operation & Development), and the UNESCO Institute for Statistics carries out TIMSS. The PISA assessment tests the abilities of students aged 15 years or ninth graders of junior high school and tenth graders of senior high school. TIMSS assessment tests the abilities of students aged 9 and 12 years or fourth and eighth graders (Chandra & Royanto, 2019). These two science literacy competitions are conducted assuming that students' scientific literacy must be built from an early age. The OECD report shows that the scientific literacy ranking of Indonesian students was 38th out of 41 countries in 2000, 38th out of 40 in 2003, 53rd out of 57 in 2006, 38th out of 40 in 2009, and 62nd out of 70 in 2015 (Seprianto, 2020). Based on these data, Indonesian students' scientific literacy skills need improvement. This report is a severe problem because Indonesian students' achievement tends to be low (Hardjo et al., 2018). Rubini et al. (2016) stated that
