Abstract


This study aims to analyze the effectiveness of student worksheet (SWS) based on the Prediction, Observation, Explanation (POE) learning model on increasing student Science Process Skills (SPS). The research method used is quasi-experimental with a non-equivalent control group design. The selection of research samples was conducted using a cluster random sampling technique from the population of students of class XI SMAN 2 Painan for the 2021-2022 school year so that class XI MIPA1 and XI MIPA 2 were obtained as samples. The data analysis technique is carried out by quantitatively analyzing the results of observation of the attitudes and skills of students. At the same time, the knowledge aspect uses a two-average comparison test. The results showed that in the attitude aspect, 91.67% of students were in the competence of attitudes A and B. The knowledge aspect showed a difference in the average SPS of experimental class students and control classes with a t count of 5,779, while the t table was 1,994 (tcount > ttable). Meanwhile, in the skill aspect, 91.67% is above the minimum completeness criteria. It is concluded that SWS, based on the POE model, can improve the SPS of students in terms of attitudes, knowledge, and skills effectively.
