<![CDATA[This study aims to determine the improvement of students’ science process skills through the implementation of Guided Problem Based Learning (GPBL) oriented toward Education for Sustainable Development (ESD) on simple machines material. This study employed a pre-experimental method with a one-group pretest-posttest design involving 34 students of class VIII F at SMPN 2 Krian. The research instruments consisted of an observation sheet of learning implementation, a science process skills test, and a student response questionnaire, while the data were collected through observation, tests, and questionnaires. The results showed that the N-Gain value was 0.55, which falls into the moderate category. The paired sample t-test results indicated a significance value (p < 0.001), meaning that there was a significant difference between pretest and posttest scores. In addition, students’ responses were categorized as very positive. Overall, the results of this study indicate that the implementation of GPBL oriented toward ESD is able to significantly improve students’ science process skills and generate positive responses toward the learning process on simple machines material.]]>
