Abstract

Scientific literacy is one of the skills that can meet all of the twenty-first century's educational demands. Educators are still struggling to find appropriate instructional tools for teaching these skills.  Collaborative learning is considered a suitable model to train students' scientific literacy skills because collaborative activities can encourage students to be active in learning activities.  The purpose of this research is to determine how effective learning tools based on collaborative learning are in improving high school students' scientific literacy skills in ecosystem materials. The type of research used is descriptive quantitative research with one group pretest-posttest research design. This study involved 30 students of X graders in Senior High School 1 Ngunut. The N gain score, paired sample t-test, and a sensitivity test are used to determine the learning tools' efficacy. Science skills exam questions are provided in 12 essay questions and are developed using scientific literacy indicators. The results showed an increase in the value of the science literacy skills test with an N gain value of 0.67, the sig value below 0.000, and a sensitivity of 0.48 The final result shows that collaborative learning are effectively used to improve students' scientific literacy skills.

Abstract

Scientific literacy skills are a person's ability to understand and construct scientific concepts so that they can apply them scientifically to respond to environmental issues and solve their problems. This skill is essential to train students so that students are more involved and active in learning. The low level of scientific literacy skills and student activity is a problem that is often faced by Indonesian teachers. This study aims to improve scientific literacy skills and student activity through problem-based learning based on a differentiated learning approach. This type of research is Classroom Action Research (CAR), which consists of four stages: planning, action, observation, and reflection. Data collection techniques in this study are observation and tests. The research instrument was an observation sheet to determine student learning activities, while a test sheet was used to determine students' literacy skills. Based on the study's results, it showed an increase in scientific literacy skills and student activity in each cycle. This can be seen from the N-gain value of the first cycle (0.63) and the second cycle (0.71), and the average of student activity in the first cycle (70.32%) and the second cycle (88.44%). Thus, it can be concluded that the implementation of problem-based learning based on a differentiated learning approach can improve scientific literacy skills and student activity.
