AbstractActiveness and cognitive learning outcomes of students are important things to achieve success in the learning process. However, the fact is that the activeness and cognitive learning outcomes of students in a private high school in Tomohon, North Sulawesi are still not optimal in the online learning process carried out by the author. This is because the teacher is less precise in choosing and implementing learning methods. To overcome this, the author uses the discussion method in online learning. This research using the descriptive qualitative method aims to describe the implementation of the discussion method in developing the activeness and cognitive learning outcomes of students in online learning. The instruments in this study consisted of the teacher's reflection journal, lesson plans, and test of students' cognitive learning outcomes. With the research subject of class XI IPA 2 students, totaling 27 students. The results showed that there was a development in students' activeness and cognitive learning outcomes after applying the discussion method. In conclusion, a discussion process such as dividing students into small groups can provide broad opportunities for students to be active during learning so that students can be directly involved in solving problems and lead to optimal learning outcomes.Keywords: activeness; cognitive learning outcomes; discussion method AbstrakKeaktifan dan hasil belajar kognitif siswa merupakan hal penting untuk mencapai keberhasilan pada proses pembelajaran. Namun faktanya keaktifan dan hasil belajar kognitif siswa di salah satu SMA swasta di Tomohon, Sulawesi Utara masih belum maksimal pada proses pembelajaran daring yang dilakukan penulis. Hal ini dikarenakan kurang tepatnya guru dalam memilih dan menerapkan metode pembelajaran. Untuk mengatasi hal tersebut penulis menggunakan metode diskusi pada pembelajaran daring. Penelitian yang menggunakan metode kualitatif deskriptif ini bertujuan untuk mendeskripsikan pelaksanaan metode diskusi dalam mengembangkan keaktifan dan hasil belajar kognitif matematika siswa pada pembelajaran daring. Instrumen dalam penelitian ini terdiri dari jurnal refleksi guru, RPP, dan tes hasil belajar kognitif siswa. Dengan subjek penelitian siswa kelas XI IPA 2 yang berjumlah 27 siswa. Hasil penelitian menunjukkan adanya perkembangan dalam keaktifan dan hasil belajar kognitif siswa setelah menerapkan metode diskusi. Kesimpulannya melalui proses diskusi seperti membagi siswa dalam kelompok kecil dapat memberikan kesempatan yang luas kepada siswa untuk aktif selama pembelajaran sehingga siswa dapat terlibat langsung menyelesaikan masalah dan berujung pada optimalnya hasil belajar.Kata Kunci: hasil belajar kognitif siswa; keaktifan; metode diskusi DOI: http://dx.doi.org/10.23960/mtk/v10i1.pp16-26

Initiative is an attitude that makes a person compelled to do something without any outside force. Every student-teacher should take initiative in order to teach and serve their students well. This student-teacher attitude appeared to develop during the students’ first internship. By taking initiative, student-teachers can learn more and enjoy every process of learning outside the classroom environment, which currently happens directly in the school. In addition, through this attitude, student-teachers can more easily interact with and adapt to the school environment in which they are placed to carry out this first internship. In line with the development of the attitude and character of the student teachers, the call to service as a teacher is even more fortified.BAHASA INDONESIA ABSTRAK: Inisiatif merupakan sikap yang membuat seseorang terdorong untuk melakukan sesuatu tanpa adanya perintah terlebih dahulu. Sikap inisiatif perlu dimiliki oleh setiap guru agar dapat mendidik dan melayani setiap siswanya dengan baik. Sikap inisiatif mahasiswa guru selama Program Pengenalan Lapangan 1 ini terlihat mulai berkembang sejalan dengan pelaksanaan program ini. Melalui sikap insiatif, mahasiswa guru dapat belajar lebih dalam dan menikmati setiap proses pembelajaran di luar lingkungan kelas, yaitu saat terjun langsung ke sekolah. Selain itu, melalui sikap ini pun, mahasiswa guru dapat dengan lebih mudah berinteraksi dan menyesuaikan diri dengan lingkungan sekolah di mana mereka ditempatkan untuk melaksanakan PPL I ini. Sejalan dengan perkembangan sikap dan karakter mahasiswa guru, panggilan untuk melaksanakan tugas pelayanan sebagai seorang guru pun semakin diteguhkan.

The purpose of the research is to describe the process of establishing students teachers' understanding about interactions in learning, describing those various understandings obtained as results of the field ecperience (PPL 1), how tasks and stages are designed according to the blue print of PPL1 to create holistic learning for prospective students of mathematics education teachers. The research method was descriptive qualitative by analyzing in depth the results of written interviews of students, through their reflections, and student observation sheets consisting of 30 students of mathematics education disseminated in several Christian schools. The data was validated with triangulation techniques, namely interviews, student reflections and student portfolios. In PPL 1, students observe and collaborate with mentor teachers and are directly involved in one-week learning activities. Through the journal of reflection students also help students to develop their understanding of the responsibility of the teacher and give direction for students can take steps to improve in the future if later become a teacher in the school. Students gained new understanding of interaction in the classroom, i.e. students understand the important of teachers to greet students before starting learning, the use positive words, recognize student names, show students' involvement in learning. Teacher students got good example and were prepared to be teachers who can build students' personal through interactions formed by teachers in the classroom. In addition, students also understood the steps to build good interaction with students. The implementation of PPL-1 is monitored in a structured manner, students were placed in a school environment that maximizes them to learn the correct practices and values of Christian education from teachers, principals, school environments and lecturers.

Pola pikir zaman sekarang yang menuntut segala sesuatu menjadi serba cepat dan instan sering kaliterbawa oleh siswa di sekolah. Ketika mengerjakan soal, siswa akan merasa puas ketika merekasudah menemukan jawabannya. Entah jawabannya benar atau tidak, sangat jarang ditemui siswayang kembali mengecek pekerjaan mereka. Di dalam proses pembelajaran pun, siswa dinilaikurang mampu dalam menganalisa kelemahan dan kelebihan yang dimilikinya untuk dapatmemaksimalkan proses belajar. Mengerjakan seadanya yang penting selesai seringkali menjadislogan para siswa saat ini. Padahal kemampuan menganalisa kelemahan maupun kelebihan yangdimiliki adalah kemampuan yang penting, khususnya dalam belajar matematika. Kesadaran akankelebihan dan kekurangan ini dinamakan kesadaran metakognisi. Dalam belajar matematikaketerampilan ini perlu dikembangkan. Untuk itu artikel ini akan membahas mengenai pembelajaranmatematika dengan menggunakan pendekatan keterampilan metakognitif.

This study aims to determine the effectiveness of Moodle gamification on students' learning motivation related to online learning interest. The research subjects were selected with a purposive sampling technique, namely the class of 2018 (n=112), class of 2019 (n=98), and class of 2020 (n=60). This study uses mixed methods. Quantitative data processing, using two-way Anova to see the main effect, interaction effect, and t-test to see a simple effect. The study finds that Moodle gamification is considered quite effective in motivating students regarding online learning interest. This result draws on survey data for 2018 2019 and 2020 students showing a “yes” answer to the question “Did gamification (e.g., level up, activity completion, and activity restriction) in Moodle motivate you during your major?” is 78.40%; 83.30%; and 90.91%. These results provide information that gamification increases student motivation. The implication of this study is that when the motivation of students is formed through gamification it will develop students' abilities.

Mathematics is a subject that is considered a scourge by most students. They think that mathematics is difficult, complicated, and boring. However, if we look at the process of creation, everything in this universe (including mathematics) is God's creation and everything is really good. This truth needs to be revealed to students by the mathematics teacher. Unfortunately, many math teachers make students dislike mathematics. Therefore, this paper aims to describe the role of Christian mathematics teachers to guide students in viewing mathematics according to God's perspective. The research method used is the literature study method. The results of this study indicate that the role of Christian mathematics teachers includes: (1) appreciating and exploring mathematics first; (2) developing the four teacher competencies; and (3) understand the objectives of learning mathematics. Christian mathematics teachers also need to be careful not to fall into the sin of idolatry and pride by asking the Holy Spirit for help to be enabled in each of their ministries.BAHASA INDONESIA ABSTRACT: Matematika merupakan salah satu mata pelajaran yang dianggap momok oleh siswa. Siswa menganggap bahwa matematika itu sulit, rumit, dan membosankan. Namun jika melihat pada proses penciptaan maka segala yang ada di alam semesta ini (termasuk matematika) merupakan ciptaan Allah dan semuanya sungguh amat baik. Kebenaran ini perlu disingkapkan kepada siswa oleh guru matematika. Namun, banyak guru matematika yang justru membuat siswa tidak menyukai matematika. Oleh sebab itu, tulisan ini bertujuan untuk memaparkan peran guru matematika Kristen di dalam menuntun siswa dalam memandang matematika sesuai dengan cara pandang Allah. Adapun metode penelitian yang digunakan adalah metode studi kepustakaan. Hasil penelitian ini memaparkan bahwa peran guru matematika Kristen meliputi: (1) mengapresiasi dan menjelajahi matematika terlebih dahulu; (2) mengembangkan keempat kompetensi guru; serta (3) memahami tujuan pembelajaran matematika. Guru matematika Kristen juga perlu berhati-hati agar tidak jatuh ke dalam dosa penyembahan berhala dan kesombongan dengan meminta pertolongan kepada Roh Kudus agar dimampukan dalam setiap pelayanannya.

Integral calculus is a course where students tend to have difficulties in problem-solving. This study examines differences in mathematical beliefs in students' problem-solving skills based on mathematics prior knowledge. This study's subjects were 120 students of the Mathematics Education study program from UPH Faculty of Education. The independent variable is mathematical beliefs, the moderator variable is prior mathematics knowledge, and the dependent variable is students' problem-solving skills. This study is an ex post facto quantitative research with instruments in a Likert scale questionnaire for mathematical beliefs, problem-solving, and mathematics prior knowledge test scores. Hypotheses were tested statistically with a two-way Anova test using SPSS 16.0. The results of the study were: (1) students' problem-solving of logical consistency beliefs is higher than memorized and procedural beliefs, (2) there is an interaction between mathematical beliefs and mathematics prior knowledge on problem-solving, (3) students' problem-solving in high mathematics prior knowledge group of logical consistency beliefs is higher than memorized, and procedural beliefs, and (4) students' problem-solving in low mathematics prior knowledge group of logical consistency beliefs is lower than memorized and procedural beliefs.
