This research was quasi-experiment. The population of this study were all class X Senior High School 4 Medan totalling ten classes. Sampling was done by simple random sampling. Class X-8 as an experimental class and class X-9 as a control class with totalling 32 students. The instrument for student learning outcomes is a multiple-choice test, and KPM was an essay test. The learning outcomes and KPM posttest in experimental class with PBL models were 77.97 and 62.78 while the control class with conventional learning was 70.3 and 41.8. Hypothesis testing shows the final learning outcomes and KPM of the two classes were different. The results concluded that there was an influence of PBL model on student learning outcomes and students’ KPM, there was an improvement of PBL model on student learning outcomes and students’ KPM, and an improvement in each indicator of KPM in the experimental class was bigger than conventional class.Keywords: problem-based learning, learning outcomes, problem-solving skills

Abstract

Based on the PISA 2022 results, the scientific literacy abilities of Indonesian students are still below the international average. This research aims to see the level of scientific literacy abilities of junior high school students in Medan City in 2023. This research was carried out at several representative schools designated by researchers as schools representing sub-districts in Medan City. Sample selection was carried out using stratified random sampling. From the 21 sub-districts in the city of Medan, one superior junior high school in each sub-district was selected. From the 21 selected schools, 1 superior 8th grader from that school was taken from each school. The instruments used are scientific literacy questions which have previously been developed by researchers following the indicators set out in the PISA 2018 framework which consists of 15 indicators for 3 scientific literacy competencies in the PISA 2018 framework. It can be concluded that the average scientific literacy ability of students in Medan City was still in the sufficient category. Student achievement was still low in several PISA 2018 framework scientific literacy competency indicators
