Analogy reasoning is the process of thinking logically and analytically in drawing conclusions based on the similarities between the two things being compared. The purpose of this study is to describe the analogy reasoning of students in solving mathematical problems in terms of high, medium, and low mathematical abilities. This research is a descriptive study with a qualitative approach. Data collection was carried out in class IX-H of SMP Negeri 5 Surabaya in the 2019/2020 school year by 33 students and each subject was selected for each category of mathematical ability. The results of the analysis of Problem Solving Tests and interviews show that students with high, medium, and low mathematical abilities mention information that is known and what is asked for logical reasons on the source and target problem, and explain the relations between the information. This indicates that each subject has an encoding process. Each subject also mentions and explains the concepts used to solve source problems, which means each subject has an inferring process. The difference is, subjects with high mathematical ability mention the same concepts between the source problem and the target problem and explain the concepts used to solve the target problem, then students can complete the target problem. This means that the subject is doing two other processes, namely mapping and applying. Subjects with medium mathematical abilities are mentioning the same concept between the source problem and the target problem but cannot explain the concept used in the target problem. However, the subject only did one of the two indicators in the mapping process, so the analogy reasoning process carried out by the subject was encoding and inferring. While students with low mathematical abilities are stopped in the encoding and inferring processes. Keywords: Analogy Reasoning, Mathematical Abilitiy

AbstrakMatematika sangat penting untuk menumbuhkembangkan kemampuan berpikir siswa serta menanamkan pendidikan karakter pada diri siswa sehingga dengan kemampuan itu diharapkan peserta didik mampu bertahan hidup dalam keadaan yang tidak pasti dan kompetitif. Namun sampai saat ini sebagian besar siswa tidak menyukai dan bahkan benci dengan matematika karena mereka merasa matematika adalah sesuatu yang membosankan dan menakutkan. terdapat bukti dengan masalah umum matematika seperti rendahnya rata-rata NEM nasional, rendahnya daya saing di ajang internasional serta rendahnya minat belajar matematika. Banyak upaya-upaya yang telah dilakukan oleh pakar pendidikan matematika di Indonesia bahkan di negara-negara maju pun melakukan banyak inovasi-inovasi pendidikan khususnya pada matematika. Indonesia sendiri tengah dipopulerkan Pembelajaran Matematika Realistik Indonesia atau disingkat PMRI. Metode yang digunakan dalam penelitian ini adalah metode penelitian kualitatif yang akan menghasilkan data deskriptif berupa kata-kata tertulis atau lisan dari subjek yang diamati. Teknik pengumpulan data yang digunakan adalah dengan menggunakan metode observasi, metode angket, metode wawancara, dan dokumentasi. Hasil penelitian ini bahwa Perkembangan PMRI di Jawa Barat khususnya Bandung Barat belum berkembang maksimal sesuai yang diharapkan pada saat pertama kali PMRI dikenalkan di Indonesia. Hal ini dapat dilihat hanya beberapa yang menerapkan PMRI itu sendiri di sekolah. Pada saat sekarang ini LPTK-LPTK sudah mulai jarang mengadakan pelatihan/workshop, seminar dan juga penelitian yang bertemakan PMRI. Kemudian ditunjang juga bahwa kurang adanya dukungan dari pemerintah mengenai PMRI. Sehingga, PMRI dalam perkembangannya belum menyebar secara menyeluruh di Bandung Raya.AbstractMath is very important to develop students' thinking skills and instill character education on students with abilities so that learners are expected to survive in an uncertain and competitive . However, to date most of the students do not like and even hate math because math is something they feel boring and intimidating . there is evidence of the general mathematical problems such as low national average NEM , low competitiveness in the international arena as well as the lack of interest in learning mathematics . Many efforts have been made by experts of mathematics education in Indonesia, even in developed countries also do a lot of innovations in education, especially in mathematics . Indonesia is in the midst popularized Realistic Mathematics EducationIndonesia or abbreviated PMRI. The method used in this study is a qualitative research method that will generate descriptive data in the form of words written or spoken of the subject being observed. Data collection techniques used is to use the method of observation , questionnaire , interview, and documentation .

Background. Student reasoning in learning mathematics contributes significantly to the achievement of student mathematics learning outcomes. The main objective of this study is to investigate the process of reversible reasoning in students for inverse problems, in the case of Adjie (Ad). The research method used to reveal the reversible reasoning in Adjie's case using descriptive qualitative research methods. Sampling was carried out using purposive sampling technique where the research sample was selected based on reversible reasoning criteria. Retrieval research data uses the results of students' mathematical work, think aloud, interviews, and the components that cause reversible reasoning. The results of our study found that the process begins with an obstacle that causes Ad to be unable to continue the resolution process, resulting in a metacognition process by analyzing the problem again analytically and developing other heuristic strategies. Ad shows a change in perspective where he initially interpreted inverse as the act of swapping independent and dependent variables and switched to interpreting inverse as the opposite of a function process involving analogy and image representation. The contribution of this research provides knowledge that reversible reasoning can occur in understanding and solving mathematical problems in inverse material.

Initial Knowledge

The success of students in taking mathematics lessons also greatly affects the factor of their initial mathematical abilities. Students' initial mathematical abilities are prerequisite abilities that students have before participating in the learning material that will be given. Therefore, students' initial knowledge is indeed an important part of students so that they have good abilities in solving a mathematical problem. (Depdiknas, 2005) states that students' initial knowledge is important for teachers to know before starting with their learning. In addition, students' initial mathematical abilities are also useful as a foothold in the beginning of each student's mathematics so that the teacher will find it easier determine a method or strategy that is suitable for use in the classroom so that the learning that is carried out will be more effective and efficient, (Fatimah, 2016: 13). The results of a preliminary study conducted on class VII teachers of SMPIT Ulil Albab Pematangsiantar shows that teachers have not identified students' initial mathematical abilities as a supporting factor for the success of learning mathematics. The same thing was expressed by (Suprapta, Suharta, & Irawan, 2016: 69) yang stated that most teachers tend to directly explain the subject matter to be discussed without wanting to know the ability of students' prior knowledge. Even though good learning provides opportunities for students to connect initial knowledge with new knowledge on the material being studied, train students' skills and abilities in the classroom.
