Abstract

PISA (Program for International Student Assessment) is an international assessment designed to measure students' literacy abilities in various disciplines, including science. This research aims to analyze the scientific literacy abilities of students at MTS Nurul Huda Situbondo in solving PISA Science questions. The research method used is data analysis from the results of the PISA Science test given to students. The data described includes test results based on problem-solving and reasoning assessment rubrics. The research results show that most students need help solving these questions, such as understanding questions well, misinterpreting images, applying scientific knowledge, and relating them to real life. The results of the analysis also show that there is significant variation in abilities among students. The results of the Kruskal Wallis-H test show a p-value <0.05, which means there is a substantial difference between the 3 dependent variables. Some students demonstrate scientific literacy in analyzing and solving PISA science questions, while others still need further assistance. The research results will provide insight into the challenges in solving PISA Science questions by students and improving science education at MTS Nurul Huda Situbondo. Understanding and overcoming these obstacles can prepare students to compete globally, especially in science.

Abstract

This study aims to describe the influence of parental income on students' learning motivation. This study uses a descriptive qualitative approach. The subjects of this study consisted of 30 students in grade VII. The results showed that the majority of students came from families with low incomes, and this had an impact on students' low learning motivation. The level of parental income influenced the learning motivation of students in the subject of science (Biology) in grade VII at SMP Negeri 20 Sigi. The researcher found several students whose parents had low incomes so that it influenced the students' learning motivation, from the 30 samples that the researcher used, there were 26 students with low incomes with incomes <Rp.500,000 and those with high incomes were 4 students with incomes of Rp. 1,000,000 - Rp. 1,999,999. The average student learning motivation only reached 36%, which is included in the very low category. Internal factors (31%) and external factors (42%) both play a role in decreasing students' learning motivation. Interventions such as scholarships and support from parents and schools are needed to increase students' enthusiasm for learning. Thus, it can be concluded that the learning motivation of class VII students at SMP Negeri 20 Sigi is very low.

Abstract

This study aims to examine the effectiveness of implementing the Student Teams Achievement Divisions (STAD) learning model in improving the cooperative skills of fourth-grade students at SDN 12 Palu. The study employs a Classroom Action Research (CAR) approach consisting of four stages: planning, action/implementation, observation, and reflection. The research subjects were 23 students from Class IVB who participated in cooperative learning using the STAD method. Data were collected through observations over three sessions, using observation sheets to assess five aspects of collaborative skills: contribution, time management, problem-solving, working with others, and investigation techniques. The results of the study indicate a significant improvement in each aspect of cooperative skills following the implementation of STAD. The average scores for contribution increased from 2.89 to 3.46, time management from 2.66 to 3.29, problem-solving from 2.38 to 3.31, working with others from 2.92 to 3.23, and investigation techniques from 2.13 to 3.23. These findings suggest that the STAD model can enhance students' cooperative skills at the elementary school level. This research also reinforces previous findings, which state that STAD is not only effective in improving academic achievement but also in developing students' social and emotional skills. Therefore, implementing STAD can serve as an effective alternative to improving the quality of learning in elementary school classrooms.
