The linear algebra applications available today usually only provide the result. So, it is a challenge to overcome this, and innovation is needed in the computing aspect. One of the popular and open-source programming languages is R. The computational innovation in R needs to be explored further, to explore the R programming logic. The creation of a function environment with the list function and the involvement of local and global variables/objects has received little attention. Based on the problems formulated, this study proposes two objectives, namely (1) developing an R program that is able to provide interactive and step-by-step solutions, to obtain a solution of a system of linear equations, and (2) to explore R’s ability to create and handle global variables. An R program is created, starting with creating a function environment. This function environment is filled with four related functions, namely “exchange”, “multiply”, “fold”, and “yield”. These four functions are connected to each other through a global object. Users can type in each function to perform row/column operations, interactively and step by step. The environmental function in this program, is named OBE. The OBE function accepts input in the form of a coupling matrix derived from a system of linear equations. The final result of this interactive process chain is given by the “result” function. The result function will display two matrices, namely the Original Matrix which is the input and the Equivalent Matrix.

“…Lecture activity is one of the activities to shape human character who is pursuing levels in tertiary institutions [1]. Someone who is educated at a tertiary level is already at the stage of child development according to Piaget, where the environment is a key factor in the formation of human character [2].…”

“…According to Maulyda et al [3] education itself aims to form individuals who are capable of community and useful both for themselves and for others. In relation to mathematics education, the objectives of mathematics education are (1) an emphasis on the ability to arrange students' reasoning and personality (formal goals); and (2) emphasis on the application of mathematics both in mathematics and outside mathematics (material goals) [4]. These two goals should be realized in a balanced way.…”

Interaksi social yang terjadi antar individu di dalam matematika disebut sosiomatematik. Norma Sosiomatematik merupakan aturan-aturan yang berasal dari nilai-nilai matematika yang dibawa ke dalam konteks sosial. Norma sosiomatematik dipandang mampu meningkatkan pemahaman peserta didik. Fokus utama dalam penelitian ini adalah, (1) Menganalisa konten sosial pada mata kuliah Pembelajaran Matematika SD; (2) Memaparkan proses interaksi sosial pada subjek penelitian; dan (3) Mendeskripsikan hubungan antara interaksi sosial dan hasil belajar matematika. Jenis penelitian ini adalah kuantitatif dengan pendekatan deskriptif. Penelitian dilaksanakan pada tanggal 15 September 2020 kepada 100 mahasiswa PGSD sebagai subjek penelitian. Pemilihan subjek penelitian ini didasarkan pada mahasiswa yang telah menyelesaikan mata kuliah pembelajaran matematika SD, karena data hasil UAS mata kuliah ini akan dijadikan data primer dalam analisis data selanjutnya. Teknik pengumpulan data menggunakan metode survey dan analisis hasil UAS matematika mahasiswa. Analisis data menggunakan analisis regresi linier sederhana. Dari penelitian, diperoleh hasil: (1) Konten matematika dalam proses perkuliahan sudah dimunculkan oleh dosen. Sistem perkuliahan yang berbentuk diskusi kelompok dapat meningkatkan kemampuan komunikasi, keberanian dan kerjasama yang dimiliki mahasiswa. (2) Gambaran interaksi sosial mahasiswa dapat dimodelkan. Model interaksi sosial menunjukan interaksi sosial dapat berbentuk asosiatif dan disosiatif. (3) Ada hubungan antara interaksi sosial dengan hasil belajar matematika. Hubungan tersebut cukup kuat, dan interaksi sosial berpengaruh terhadap hasil belajar matematika mahasiswa.

“…The next stage in the mathematical connection indicator is to carry out a mathematical process. According to [22] mathematical processes will always require holistic connections between concepts. The sequence of concepts in mathematics is very clear, because mathematics always departs from one definition or theorem [17].…”

Mathematical connection is an important aspect of learning mathematics. Especially for elementary school teachers, where since the 2013 curriculum was launched lowgrade elementary school teachers (Class I, II, and III) are obliged to implement a thematic learning system. In thematic learning, many mathematical connection processes occur. Therefore, the researcher aims to explore teachers' understanding and experiences in integrating students' mathematical connection skills into classroom learning. The research method used is a qualitative-descriptive method to describe the learning phenomenon based on mathematical connections. The research subjects were 24 elementary school teachers in cluster IV Mataram City with the criteria; (1) The length of teaching is more than seven years (since the 2013 curriculum was issued); (2) Teachers who teach in Low class (Class I, II, & III); and (3) The teacher is willing to be a subject in the research. The research procedure carried out was the provision of an online google form survey link. Then it was done to each subject via WhatsApp call to strengthen the survey answers for each subject. Data analysis was conducted descriptively using mathematical connection indicators in NCTM. The results showed that the implementation of learning based on mathematical connections was not optimal, where only indicators D1 and D2 were met. The D3 indicator is not fulfilled, which means that the teacher never makes student worksheets (LKS) that contains or connects mathematical concepts with condep outside mathematics.
