Abstract

The Goldbach Conjecture, one of the oldest problems in mathematics, has fascinated and inspired many mathematicians for ages. In 1742 German mathematician Christian Goldbach, in a letter addressed to Leonhard Euler, proposed a conjecture. The modern-day version of the Binary/Strong Goldbach conjecture asserts that: Every even integer greater than 2 can be written as the sum of two primes. The conjecture had been verified empirically up to 4 × 1018, its proof however remains elusive, which seems to confirm that:Some problems in mathematics remain buried deep in the catacombs of slow progress ... mind stretching mysteries await to be discovered beyond the boundaries of former thought. Avery Carr (2013) The research was aimed at exposition, of the intricate structure of the fabric of the Goldbach Conjecture problem. The research methodology explores several topics, before the definite proof of the Goldbach Conjecture can be presented. The Ternary Goldbach Conjecture Corollary follows the proof of the Binary Goldbach Conjecture as well as the representation of even numbers by the difference of two primes Corollary. The research demonstrates that the Goldbach Conjecture is a genuine arithmetical question.

Abstract

Based on PISA research, Indonesian students' mathematical abilities are still below average with one of the assessment indicators being critical thinking skills. This was also found by the authors at the observed schools. The average percentage of students' critical thinking skills in grade 8 is 36% or at less intervals. Meanwhile, the problem-based learning model (PBM) is seen as effective in helping students' critical thinking skills. Thus, the purpose of this study is to describe the critical thinking skills of grade 8 students using the problem-based learning model. The research method used is descriptive qualitative. The conclusion of this paper shows that students' critical thinking skills using the PBM model have an average percentage of 65% for the three indicators. The characteristics of PBM by providing contextual problems can train students' critical thinking power. The stages in PBM make students actively involved in learning by asking various questions as well as in group discussions in designing problem solving. In Christian education, students' critical thinking skills are trained to be able to understand God's truth. Through this, students are expected to live responsibly. Suggestions that can be given are to train students' critical thinking skills in schools through appropriate learning models or approaches. In the implementation of PBM, it is better to pay attention to the estimated time in each stage.BAHASA INDONESIA ABSTRAK: Berdasarkan penelitian PISA, kemampuan matematika siswa Indonesia masih di bawah rata-rata dengan salah satu indikator penilaiannya ialah kemampuan berpikir kritis. Hal ini juga ditemukan oleh penulis di sekolah yang diobservasi. Persentase rata-rata kemampuan berpikir kritis siswa kelas VIII ialah 36% atau pada interval kurang. Sementara itu, model pembelajaran berbasis masalah (PBM) ditinjau efektif dalam membantu kemampuan berpikir kritis siswa. Sehingga, tujuan penelitian ini ialah untuk memaparkan kemampuan berpikir kritis siswa kelas VIII melalui model pembelajaran berbasis masalah. Metode penelitian yang digunakan adalah kualitatif deskriptif. Kesimpulan penulisan ini menunjukkan bahwa kemampuan berpikir kritis siswa melalui model PBM memiliki persentase rata-rata untuk ketiga indikatornya sebesar 65%. Karakteristik PBM dengan pemberian masalah kontekstual dapat melatih daya pikir kritis siswa. Tahapan dalam PBM membuat siswa terlibat aktif dalam pembelajaran dengan mengajukan berbagai pertanyaan juga dalam diskusi kelompok dalam merancang penyelesaian masalah. Dalam pendidikan Kristen, kemampuan berpikir kritis siswa dilatih untuk dapat memahami kebenaran Allah. Melalui hal tersebut, siswa diharapkan hidup bertanggung jawab. Saran yang dapat diberikan adalah melatih kemampuan berpikir kritis siswa di sekolah melalui model atau pendekatan pembelajaran yang sesuai. Dalam pelaksanaan PBM, sebaiknya memperhatikan estimasi waktu dalam setiap tahapannya.

Abstract

Transparency is an attitude of life that can be used as a role model for others.  The role of the teacher as a role model in the classroom can be implemented through ways of speaking and behaving with students. Therefore, to be a role model for students, a teacher must have good personality competencies. However, as the author experienced, Practice Field Experience Christian teachers are not yet capable of having good personality competencies. This is because they have not been able to control and manage emotions when faced with problems that occur in teaching online. In addition to explaining the personality competence of Christian teachers, the writing of this article aims to outline the efforts of the author, as a Christian teacher, in improving personality competencies to become a role model for students. The research method used is qualitative descriptive. This method is done by revealing facts, phenomena, variables, and circumstances that occur during the research. The results of the research are described based on real situations.  Based on the results of this research, it can be concluded that to improve the personality competence of a Christian teacher, there needs to be an effort to deepen the personal relationship with God through understanding the Word of God. If a Christian teacher has improved personality competence by learning the Word of God, then a Christian teacher in practice will be a role model for students.BAHASA INDONESIA ABSTRACT: Keteladanan adalah sikap hidup yang dapat dijadikan panutan bagi orang lain. Peran guru sebagai seorang teladan di dalam kelas harus diimplementasikan melalui cara berbicara dan bersikap yang baik dengan siswa. Oleh karena itu, untuk menjadi teladan bagi siswa seorang guru harus memiliki kompetensi kepribadian yang baik. Pada kenyataannya, ketika Praktek Pengalaman Lapangan 2 penulis sebagai seorang guru Kristen belum cakap memiliki kompetensi kepribadian yang baik. Hal ini dikarenakan penulis sebagai seorang guru Kristen belum dapat mengontrol dan mengelola emosi ketika dihadapkan dengan suatu masalah yang terjadi dalam mengajar secara online. Selain menjelaskan kompetensi kepribadian guru Kristen, penulisan artikel ini bertujuan untuk menguraikan upaya penulis sebagai seorang guru kristen dalam memperbaiki kompetensi kepribadian untuk menjadi teladan bagi murid. Adapun metode penelitian yang digunakan dalam penelitian ini adalah metode deskriptif kualitatif. Metode ini dilakukan dengan mengungkapkan fakta, fenomena, variabel dan keadaan yang terjadi saat penelitian berlangsung. Hasil penelitian kemudian dideskripsikan berdasarkan situasi nyata.  Berdasarkan hasil penelitian, dapat disimpulkan bahwa untuk memperbaiki kompetensi kepribadian guru Kristen perlu adanya upaya memperdalam hubungan pribadi dengan Tuhan melalui pemahaman akan Firman Tuhan. Jika seorang guru Kristen sudah memperbaiki kompetensi kepribadian dengan belajar Firman Tuhan, maka seorang guru Kristen dalam prakteknya akan menjadi panutan bagi siswa.

Abstract

School math learning is part of the educational process that provides students with a mathematics learning experience through a planned set of activities to achieve established goals. The goal of learning mathematics in schools in Indonesia is oriented towards achieving a balance between the cognitive, affective, and psychomotor domains. In fact, learning mathematics in schools in Indonesia so far has focused on efforts to achieve high scores from the cognitive domain. But along with the development and change of curriculum, affective and psychomotor domains are receiving more priority to develop. In this paper, the author wants to examine the affective domain by conducting a study of character values in school mathematics learning through an analogy approach. This paper aims to contribute ideas related to the development of affective domains in learning mathematics through the study conducted. The research method used is a literature study. While the strategy for conducting the study is an analogical approach that is associated with the understanding of quantitative and qualitative relationships. Based on the results, it is evident that in school mathematics learning implied character values are learned. The author hopes that this study will be useful to math teachers in developing the affective domain of math learning in schools. The implication is that the goal of learning mathematics, namely the balance between the cognitive, affective, and psychomotor domains, can be achieved.BAHASA INDONESIA ABSTRACT: Pembelajaran matematika sekolah adalah bagian dari proses pendidikan yang memberikan pengalaman belajar matematika kepada siswa melalui serangkaian kegiatan yang terencana untuk mencapai tujuan yang telah ditetapkan.

Abstract

The digital era is synonymous with the use of technology that is beneficial for education. The use of technology must be balanced with character education to provide direction to students in utilizing technology. The decline in character in the digital era is evidence that character education has not been implemented optimally so that students deviate from the use of technology and internet networks. Teachers play an important role in overcoming character decline by instilling character values based on Christian ethics based on the Bible. Christian ethics is the basis for providing character education in the digital era. The purpose of this study was to determine the teacher's role in implementing character education to overcome the decline in student character in the digital era which was reviewed based on the study of Christian ethics. The method used is a literature review, namely a description of reading materials that are relevant to the research topic. Based on the literature review that has been carried out, it can be concluded that teachers have an important role in implementing character education to overcome the decline in student character in the digital era. The teacher has a role as an agent of reconciliation who guides students to have a Christ-like character with the aim of developing a Christian mindset, social responsibility, mental, physical, and social health and preparing students for the world of work.BAHASA INDONESIA ABSTRACT: Era digital identik dengan penggunaan teknologi yang bermanfaat bagi pendidikan.
