During the Covid-19 pandemic, online learning became a new way of teaching and learning which utilized electronic devices, especially internet networks. However, in practice, online learning often encounters obstacles. With online learning, teachers need to know the causes and indicators of these difficulties. Efforts can then be made to alleviate them, namely that teachers become facilitators of online learning activities. In their role as facilitators, teachers can provide their students with supportive learning resources and media, encouragement and motivatation, and time outside of school hours to help students understand well. In this case, the author used a literature review and case study methods as the basis for preparing research instruments with the purpose of this paper being to explain the role of the teacher as a facilitator in overcoming learning difficulties of students during online learning. The author is aware of the limitations that humans have so the learning difficulties that students experience can be seen as an opportunity for teachers to serve those students. Teachers are also required to be more responsible for themselves and their students as a form of gratitude to God. The author suggests that the teacher as a facilitator can continue to learn to better understand the various strategies in overcoming learning difficulties and have a sense of responsibility towards students.BAHASA INDONESIA ABSTRACT: Dalam masa pandemi seperti ini, pembelajaran daring menjadi cara baru dalam proses belajar mengajar dengan memanfaatkan perangkat elektronik, khususnya jaringan internet.

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.

Statistics for Research Education is an important course for students in the Faculty of Education. Serious problems are experienced by students learning statistics, one of them is because the learning outcomes are not optimal. To overcome this problem, a lecturer can provide mini-research tasks. Mini-research is one form of assignment from project-based learning. This research was descriptive qualitative research. The subjects in this study were students from Cohort 2019 who took Educational Research Statistics courses. Learning activities and mini-research assignments are handled fully online. By giving students a mini-research assignment, students can be encouraged to learn statistical theories and concepts. Through mini-research tasks, students can increasingly see the big picture and interrelationships between topics in this course. The positive responses can be seen from students’ reflections and results of the review given to the paper. The use of project-based learning with a mini-research task is an interesting idea and suitable for students. In addition to better student learning outcomes, students also become more conscious of the problems around them. Prospective teachers can learn to make research an upcoming provision when they enter the field of teaching.

One of the most typical problems experienced during the learning process for mathematics is the lack of student motivation in their studies. To assist students in resolving this problem, the teacher's position as a motivator is essential. It is hoped that the teacher's passion will increase the student's interest in studying, resulting in a successful learning process. This study asks the following question: How can a teacher pique a student's interest in mathematics? The purpose of this study is to examine the significance of the teacher's role as a motivator in promoting students' excitement for learning. Techniques for qualitative research were used to write this essay. The study's subject population consisted of 39 students in grades IX-A and IX-C. Reaching learning goals is hampered by learning problems. For students to achieve these goals, the teacher must be able to motivate them. The findings of this study show that a teacher's role as a motivator can correspond to the indicators of learning mathematics interest. To make it clear how the instructor's position affects students' motivation for learning, the author suggests utilizing the teacher as a motivator more than twice.

Mathematics learning involves not only conceptual mastery but also affective dispositions that shape engagement and professional development. This study explores the affective domain of mathematical disposition among first-year prospective mathematics teachers and examines its alignment with indicators of early professional readiness. An explanatory mixed-methods design was employed involving 24 first-year students from a teacher education program in Indonesia. Quantitative data were collected using a validated affective mathematical disposition questionnaire, and differences between high- and low-disposition groups were analysed using the Mann–Whitney U test. Follow-up semi-structured interviews were conducted with six participants to explore professional motivations, conceptions of teaching competence, and professional initiative. The results indicate that usefulness and worthwhileness were the strongest affective aspects, while mathematical self-concept emerged as comparatively weaker. Statistically significant differences were found between high- and low-disposition groups across all affective aspects. Qualitative findings suggest that higher affective disposition aligns with stronger intrinsic motivation, more integrated conceptions of teaching competence, and more deliberate professional initiative. These findings provide preliminary evidence that affective mathematical disposition may play a contributory role in the early development of professional teacher identity

Guidance and assistance in learning are necessary for every child, whether it is for the students who have attended school or not. Most of the parents who live in the Bonang area can not fulfill this activity. Parents who have not be able to accompany their children in learning after school are caused several factors, namely cognitive inability of parents, the busyness of parents in work, and the inability of parents economically to send their children to learning center, and some are even do not trust some learning center. Mathematics education students are prepared in the field of school mathematics teaching and learning expertise. For them, this activity is a valuable opportunity to gain teaching experience, as well as learning to implement the theories that have been learned, both in terms of pedagogy and mathematics. The purpose of this community is as a place to synchronize students’ need to implement their learning practices with the needs of schoolchildren around Bonang. The activity is in the form of assistance at one of the residents’ houses in Bonang. The benefits of this assistance activity are felt by all parties, schoolchildren as learning participants receive learning guidance in terms of cognitive and character, parents who are assisted and feel happy to see children's development in education, and the tutors can directly learn to implement knowledge and practice teaching.BAHASA INDONESIA ABSTRACT: Bimbingan dan pendampingan belajar diperlukan oleh setiap anak, baik yang bersekolah maupun yang tidak bersekolah. Kegiatan tersebut belum dapat dipenuhi oleh sebagian besar orang tua yang berdomisili di daerah Bonang. Orang tua yang belum dapat mendampingi anak-anaknya dalam belajar sepulang sekolah disebabkan oleh beberapa faktor yaitu ketidakmampuan orang tua secara kognitif, kesibukan orang tua dalam bekerja dan ketidakmampuan orang tua secara ekonomi untuk mengikutsertakan anaknya di dalam bimbingan belajar yang bersifat komersial, bahkan ada yang kurang percaya pada bimbingan belajar tertentu. Mahasiswa pendidikan matematika dipersiapkan pada bidang keahlian belajar mengajar matematika sekolah. Bagi mahasiswa, kegiatan tersebut merupakan kesempatan yang berharga untuk mendapatkan pengalaman mengajar, sekaligus belajar untuk mengimplementasikan teori yang sudah dipelajari, baik dari segi pedagogy maupun keilmuan matematika.

Pandemic conditions are continuing and have an impact on learning. Under such conditions, perhaps students are already familiar with distance learning and adapt to those conditions. However, it is undeniable that not all children can still have good motivation during online learning. Student learning motivation must still be moved so that students' enthusiasm for learning continues to be encouraged and can follow the learning. Although there are already several schools that implement Limited Face-to-Face Learning (PTMT), students still need assistance, for example during independent study hours in developing their knowledge. Especially children of Junior High School (SMP) and High School (SMA) or Vocational High School (SMK) age 7, 8, 9, 10, and 11 are in the adolescent stage that requires attention so that they can focus on learning. One of the things that can be done to give real attention is to accompany them to study outside of school hours. Tenjo tutoring in collaboration with GKI Gading Serpong is here to answer these problems. The goal is to provide services that directly impact the needs of junior high and high school / vocational school students, especially in encouraging student learning motivation. This tutoring activity is carried out online. After being implemented for 5 months, the student's learning motivation score did not appear to have increased significantly. However, based on open-ended questions, 92% of students stated that they became enthusiastic about learning when taking this tutoring.abstract in BahasaKondisi pandemi masih terus berlanjut dan berdampak terhadap pembelajaran. Dalam kondisi demikian, mungkin siswa sudah terbiasa dengan pembelajaran jarak jauh dan beradaptasi dengan kondisi tersebut. Namun tidak dapat dipungkiri bahwa tidak semua anak bisa tetap memiliki motivasi yang baik selama pembelajaran daring. Motivasi belajar siswa harus tetap digerakkan sehingga semangat belajar siswa terus terpacu dan dapat mengikuti pembelajaran. Meski sudah ada beberapa sekolah yang melaksanakan Pembelajaran Tatap Muka Terbatas (PTMT), siswa tetap memerlukan pendampingan misalnya pada saat jam belajar mandiri dalam mengembangkan pengetahuannya. Khususnya anak usia Sekolah Menengah Pertama (SMP) dan Sekolah Menengah Atas (SMA) atau Sekolah Menengah Kejuruan (SMK) kelas 7, 8, 9, 10, dan 11 berada di tahap remaja yang membutuhkan perhatian sehingga mereka bisa fokus dalam pembelajaran. Salah satu yang bisa dilakukan untuk memberikan perhatian yang nyata adalah mendampingi mereka belajar di luar jam sekolah. Bimbingan belajar Tenjo bekerja sama dengan GKI Gading Serpong hadir untuk menjawab permasalahan tersebut. Tujuannya adalah menghadirkan pelayanan yang langsung berdampak bagi kebutuhan siswa SMP dan SMA/SMK khususnya dalam mendorong motivasi belajar siswa. Kegiatan bimbingan belajar ini dilaksanakan secara daring. Setelah dilaksanakan selama 5 bulan, secara skor motivasi belajar siswa tidak terlihat mengalami peningkatan secara signifikan. Namun berdasarkan pertanyaan terbuka, 92% siswa menyatakan menjadi semangat belajar ketika mengikuti bimbingan belajar ini.

Prospective teachers need to have good statistical literacy because they will become a decision-makers in data-based classroom learning. They must be able to determine when to change learning according to students’ progress. Prospective teachers, including Primary Student Teacher Education (PGSD) are not only able to do statistical calculations, but also as the ability to read data, interpret statistical information, and use the analysis data results as a basis for rational and responsible decision-making. This study aims to examine student statistical literacy development through contextual learning. The study used a quantitative approach with a one group pretest–posttest design, involving 72 PGSD students at one of the private universities in Indonesia. The instrument is a statistical literacy essay test. The data was analyzed using the Wilcoxon Signed Rank Test. The results showed a significant increasing in statistical literacy after the implementation of contextual learning. These findings confirm that contextual learning is effective in improving students' statistical literacy and is recommended as a pedagogical approach to strengthen the statistical literacy of prospective teachers.

Abstract Since the use of artificial intelligence (AI) in education continues to broadly expand, understanding its role in pre-service teacher development has become increasingly important. This study explores how AI used in Advanced Mathematics courses contributes to the development of pedagogical thinking among pre-service mathematics teachers. A qualitative approach was employed involving 51 students. Data were collected through questionnaires and follow-up interviews, then analyzed using thematic analysis. The findings indicate that students use AI to support their understanding of abstract mathematical concepts and solve problems through simplified explanations and structured solution steps. Students’ engagement with AI is characterized by several tensions between efficiency and understanding, assistance and dependency, and ease of use and prompt accuracy. These tensions foster reflection, metacognitive awareness, and more critical use of AI. The findings also reveal the emergence of pedagogical thinking, although it remains limited in addressing learner diversity and the complexity of instructional contexts. Abstrak Seiring dengan semakin meluasnya penggunaan kecerdasan buatan (AI) dalam pendidikan, pemahaman mengenai perannya dalam perkembangan calon guru menjadi semakin penting. Penelitian ini bertujuan mengeksplorasi bagaimana penggunaan AI dalam mata kuliah matematika lanjut berkontribusi terhadap perkembangan pemikiran pedagogis mahasiswa calon guru matematika. Penelitian menggunakan pendekatan kualitatif dengan melibatkan 51 mahasiswa. Data dikumpulkan melalui kuesioner dan wawancara lanjutan, kemudian dianalisis menggunakan analisis tematik. Hasil penelitian menunjukkan bahwa mahasiswa memanfaatkan AI untuk memahami konsep matematika abstrak dan menyelesaikan masalah melalui penjelasan yang lebih sederhana serta langkah-langkah yang terstruktur. Keterlibatan mahasiswa dalam penggunaan AI diwarnai oleh beberapa ketegangan antara efisiensi dan pemahaman, bantuan dan ketergantungan, serta kemudahan penggunaan dan ketepatan prompt. Ketegangan tersebut mendorong refleksi belajar, kesadaran metakognitif, dan penggunaan AI yang lebih kritis. Temuan juga menunjukkan munculnya pemikiran pedagogis, meskipun masih terbatas dalam mempertimbangkan keragaman peserta didik dan kompleksitas situasi pembelajaran.
