Communication is a representation of God's nature in humans who are created in His image -- Imago Dei -- and therefore, part of the nature of teachers and students. One form of communication in learning is interpersonal communication. Interpersonal communication helps teachers and students learn and carry out learning, and can fosters students' interest in learning mathematics. Based on the authors’ observations and reflections when teaching at school X, interpersonal communication in learning mathematics was present, but students were still noisy, sleeping, and did not listen to the teacher which resulted in a lack of understanding of the basic mathematical concepts. Based on this, this paper aims to analyze interpersonal communication between teachers and students in learning mathematics. The research methods is a literature review. The results of the analysis show that interpersonal communication fosters students' interest in learning mathematics. The problems that occur are due to a lack of self-confidence, a lack of recognition of students, and less attention to important factors in interpersonal communication. To overcome these three factors, it is necessary to build students’ self-confidence by fostering a positive perception of students' abilities and building a good community with teachers and the existing support system.BAHASA INDONESIA ABSTRACT: Komunikasi merupakan representasi natur Allah dalam diri manusia sebagai Imago Dei. Oleh karena itu, komunikasi merupakan natur dari guru dan siswa. Salah satu jenis komunikasi yang tepat dalam pembelajaran matematika adalah komunikasi interpersonal. Komunikasi interpersonal membantu guru dan siswa dalam belajar dan menjalankan pembelajaran, misalnya, menumbuhkan minat siswa dalam belajar matematika. Hasil observasi dan refleksi mengajar penulis di sekolah X menunjukkan terjadinya komunikasi interpersonal pada pembelajaran matematika, namun siswa masih ribut, tidur, dan kurang mendengarkan guru dalam pembelajaran yang mengakibatkan pemahaman akan konsep dasar matematika kurang. Berdasarkan hal tersebut, tujuan penulisan ini adalah untuk menganalisis komunikasi interpersonal antara guru dan siswa di dalam pembelajaran matematika. Metode penelitian ini adalah kajian literatur. Hasil analisis menunjukkan komunikasi interpersonal menumbuhkan minat belajar siswa terhadap matematika. Hal ini disebabkan karena kurangnya kepercayaan diri, kurangnya pengenalan akan siswa dan kurang memperhatikan faktor-faktor penting dalam komunikasi interpersonal. Untuk mengatasi ketiga faktor tersebut, maka siswa perlu dibangun rasa percaya diri, dengan cara menumbuhkan persepsi positif terhadap kemampuan diri dan membangun komunitas yang baik dengan guru dan support system yang ada.

The problem-solving ability between reflective and impulsive subjects from several studies shows that reflective subjects are always superior than impulsive subjects. The purpose of this study was to identificate and to describe students' problem-solving abilities with impulsive cognitive style in solving superitem test problems and their characteristics. This research is a qualitative descriptive study. The data collection techniques used were the MFFT test, the superitem test, and interviews. Based on the results of the superitem test, it shows that the two impulsive subjects have differences in achieving the level of problem-solving ability thinking. Impulsive-01 subjects can reach all thinking levels based on SOLO taxonomy while impulsive-02 subjects can only solve problems at the unistructural level. Although the research shows that the impulsive-01 subject has the characteristics of being fast, less accurate, less thorough, and seeming rushed in solving problems, the subject can finish up to the extended abstract level. The impulsive-02 is able to connect by making assumptions in solving the problem, it's just that the inability to solve this problem due to not understand the problem.

SIGMA tutoring is conducted in a church, namely the HKBP Binong Permai Tangerang. Because of the pandemic of COVID-19 in 2021, parents of church congregations have complaints about learning difficulties experienced by their children while online learning. The problem arises because the material studied by their children is quite difficult for their parents to guide. A solution is needed to overcome these problems, namely through Sigma tutoring. Sigma tutoring is implemented online by providing individual guidance for students. Online tutoring is being implemented currently according to government recommendations, it is prohibited to conduct face-to-face meetings between individuals. Even though by online learning, Sigma tutoring has a positive impact, namely that students/tutees feel helped by their learning difficulties, and tutors who are students can further hone their teaching skills through this Sigma tutoring. BAHASA INDONESIA ABASTRACT: Bimbingan belajar SIGMA dilaksanakan di sebuah gereja yakni HKBP Binong Permai Tangerang.

The measure of the center is an essential topic in statistics. Pre-service mathematics teachers must have the ability to select and use measures of center. The inability to use and select appropriate center measures indicates a low understanding of center measures. Meanwhile, research on the ability to use and select the center's appropriate measures is very limited. This study explores the sources of error for pre-service mathematics teachers in using and selecting the appropriate measures of center. This study involved 177 pre-service mathematics teachers. This research is a qualitative study using the interpretive paradigm. Data were collected using a test containing two problems and clinical interviews. Data were analyzed qualitatively using grouping participant responses based on ways of thinking and ways of understanding to use and select center measures. The results showed that pre-service mathematics teachers could not select an appropriate measure of centers because they were too focused on measures of centers while ignoring the variance. In order to be able to select an appropriate measure of centers because variance must be considered simultaneously. The implication of this study results is the need for a learning approach that introduces concurrent measures of centers with data variance.
