Abstract

This study aims to describe misconceptions about concepts, facts, principles and skills based on thinking skills that were made by fifth grade students at SD Inpres 6 Lolu in solving multiplication fraction problems. This research is descriptive qualitative research which is based on the problem solving steps put forward by Polya. The research subjects were taken by 6 students based on the level of thinking skills determined using the Standard Deviation (SD) calculation. Data collection methods used are test and interview methods. The study's findings reveal that students make different types of errors based on their thinking ability in the process of solving mathematical problems. These errors can be categorized into four main areas namely: factual errors, conceptual errors, skill errors, principal errors. In summary, the study highlights that students' thinking ability is closely linked to the types of errors they make when solving mathematical problems. These errors primarily involve faulty facts, conceptual misunderstandings, skill-related issues, and principal errors. Understanding these patterns of errors can guide educators in developing targeted interventions to improve students' mathematical problem-solving skills

Abstract

Mathematics is important to the broader implications for science education, as science and mathematics are inherently interconnected. The use of interactive and engaging media such as pop-up books can be a valuable tool for teaching natural science concepts and improving student learning outcomes. This study aims to improve students' mathematics learning outcomes through the implementation of pop-up media during the learning process. The current study also describes potential implication of the result to the natural science learning. This research is classroom action research (CAR). This research was conducted at SD Inpres Baru with 16 third grade students as subjects for two cycles. Research data were analyzed descriptively-quantitatively. Data on student learning outcomes were collected using multiple-choice tests. In addition, observation sheets are also used to collect data on teacher and student activities. The results of the research in cycle I showed that the average student score reached 68.87 with classical completeness reaching 43.75%, while the results of observations of teacher activity (68%) and students (69%) were in the sufficient category. In cycle II, the average student score increased to 87 with classical completeness reaching 87.5%. There were better teacher (89%, good category) and student (91%, very good category) activity compared to the results in cycle I. Based on the results of the study, it can be concluded that the implementation of Pop-up Book learning media in learning mathematics can improve students' learning outcomes on flat shape material. The result can be applied to natural science teaching as well, where teachers need to be more active and effective in guiding students in experiments and demonstrations, and ensure that students are actively participating in the learning process.
