Abstract

The development of mathematical reasoning is part of an important process that needs to be taught to students, as reflected in teacher education. This study focuses on the education of prospective teachers of mathematics which aims to describe the knowledge of prospective teachers about students' mathematical reasoning processes. The subjects of this study were prospective mathematics teacher students who were selected by purposive sampling. The instruments used include math assignments and interview guidelines. Data analysis techniques with data reduction, data presentation, data interpretation, and making conclusions. The results of this study indicate that the knowledge of the reasoning process carried out by prospective mathematics teachers is organized into 3 levels of knowledge in each reasoning process that appears, namely generalizing, justifying, classifying, and exemplifying. At the level of knowledge of the reasoning process, student teacher candidates still have difficulty in analyzing students' reasoning processes, using the meaning of terms in everyday life, and only considering the correct reasoning process. An important aspect of the reasoning process is developing knowledge by completing the means as a medium to understand the reasoning process in each student's learning.

Abstract

Sorogan and Bandongan learning methods that characterize learning methods in Islamic boarding schools are applied in formal institutions, especially at the Elementary School level. SD NU Banat Banin Lamongan has implemented the boarding school learning system in teaching and learning activities on Islamic Education subjects in the classroom. The results showed that the background of the implementation of the Sorogan and Bandongan learning methods in teaching of Islamic Religious Education subjects at SD NU Banat Banin Lamongan was to put more emphasis on student understanding, in addition, the application of the Sorogan and Bandongan learning methods was also very simple, so that all children students are expected to be able to understand the material quickly. In the process of implementation, it is carried out in three stages. The first is the preparation stage. The teacher always checks the readiness of his students. The second is the implementation phase. For the Sorogan method, students who get their turn to read, are told to go forward and sit facing the teacher, then read the reading text prepared in the last week. For the Bandongan method, the teacher reads and translates the reading text contained in the textbook. And the third stage is the closing stage. The teacher will give an explanation of the material that has been read and translated. Based on the results of the research, in implementing the Sorogan and Bandongan learning methods, it should be improved and improved in all activities and learning.

Abstract

The purpose of this study was to describe students' geometric thinking skills on circle material based on Van Hiele's theory (Visualization, Analysis, Informal Deduction, Deduction, Rigor). The subjects of this study were 3 students of class IX-A SMP Hang Tuah 4 Surabaya based on their initial mathematical abilities (high, medium, and low). The initial mathematical ability data was obtained from data on report cards for the even semester of the 2021-2022 academic year and based on the considerations of the mathematics teacher for class IX-A. This type of research is descriptive qualitative research. Collecting data in this study used tests and interviews. The test instrument used in this study was a circular geometry test in the form of mathematical questions with circle material arranged based on the Van Hiele indicator without stage 4 (Rigor) with the consideration that the research was conducted in class IX SMP so students have not been able to understand the material at stage 4 (rigor). Student with high initial mathematical abilities, geometric thinking abilities is already at stage 2 (informal deduction). Student with medium mathematical abilities, geometric thinking skills is at stage 2 (informal deduction). Student with low mathematical abilities, geometric thinking skills is at stage 0 (visualization).
