Abstract

The purpose of learning mathematics is to obtain life skills through problem solving. Problem solving skills are one of mathematics skills that must be possessed by students. The result of the pre-cycle in this research showed that 83.33% of students had not achieved the minimum predicate “B-” in solving non-routine problems. It proved that students’ abilities in mathematics problem solving in non-routine problems were still low. During the pre-cycle, the researcher also observed some students who were not brave enough yet to ask questions of the teacher directly during the learning process. Besides that, almost all the students still had high individualistic and low awareness. Based on the problems that happened in the class, the researcher offered the peer tutoring method as a solution to improve students’ mathematical problem-solving skills in non-routine problems. The research method used in this research was Classroom Action Research using the Kemmis and McTaggart model. The instruments used in this research were tests, observation sheets, students’ questionnaires, and journal reflections. Based on the data analysis, students’ mathematical problem-solving skills in non-routine problems improved to 29.17% by implementing the peer tutoring method with the steps (1) choosing the tutors, (2) guiding the tutors, (3) students doing the tutoring activity, and (9) evaluating the learning processBAHASA INDONESIA ABSTRAK: Tujuan dari mempelajari matematika ialah untuk memperoleh kecakapan hidup salah satunya melalui pemecahan masalah.

Abstract

In general, integral calculus courses are difficult for students because the problems involved require strong problem-solving skills. For university students, integral calculus courses also require them to do self-regulated, or independent, learning. Another aspect that makes learning difficult for these students is their mathematical beliefs and prior knowledge. This study aims to see how different types of mathematical beliefs affect self-regulated learning in terms of students' prior knowledge. This research was conducted on students in a mathematics education study program at a private university in Tangerang with a sample of 120 students. This research is an ex post facto quantitative study using a two factorial design. The variables in this study consisted of independent variables in the form of mathematical beliefs, the moderator variable in the form of students’ prior knowledge, and the dependent variable in the form of self-regulated learning. The results obtained are: (1) self-regulated learning by students with logical consistency mathematical beliefs is higher than students with memorized and procedural beliefs, (2) there is an interaction between mathematical beliefs and prior knowledge towards self-regulated learning, (3) student in the high prior knowledge gorup logical consistency beliefs had higher self-regulated learning than students with memorized and procedural beliefs, and (4) self-regulated learning in the low mathematics prior knowledge group with logical consistency beliefs is lower than students with memorized and procedural beliefs.BAHASA INDONESIA ABSTRACT: Mata kuliah kalkulus integral pada umumnya masih menjadi kesulitan bagi mahasiswa karena permasalahan yang terkandung membutuhkan pemecahan masalah yang kuat.

Abstract

Based on the results of observations made at a Christian Kindergarten in Tangerang, it was found that there was an unevenness in the numeracy abilities of early-age students. Some students already have the ability to count numbers 1 and 3, but some others do not. Therefore, it is necessary to introduce numeracy skills by the teacher so that students have an even numeracy ability. The purpose of writing this scientific work is to describe the application of the storytelling method to the numeracy skills of early-age students in thematic learning. The research method used is descriptive qualitative research method. Based on the results of the discussion, it was found that the application of the storytelling method was carried out in six stage’s that were closely related to the introduction of numeracy skills, namely making preparations before learning, checking readiness and providing motivation to students, actively involving students, telling stories with attention to language, developing, and checking student understanding.  Through the application of the six stages of the storytelling method in thematic learning it can help teachers to assess and confirm the level of numeracy abilities of early age students. The next suggestion is to pay attention to various indicators of numeracy skills that have not been studied and to pay attention to the time allocation in teaching so that the effectiveness of the six stages of the storytelling method can be assessed.BAHASA INDONESIA ABSTRACT: Berdasarkan hasil observasi yang dilakukan pada salah satu Taman Kanak-kanak Kristen di Tangerang ditemukan ketidakrataan kemampuan numerasi siswa usia dini. Beberapa siswa telah memiliki kemampuan membilang bilangan 1 dan 3 namun beberapa lainnya belum. Oleh sebab itu, diperlukan pengenalan kemampuan numerasi oleh guru agar siswa memiliki kemampuan numerasi yang merata. Tujuan penulisan karya ilmiah ini adalah memaparkan penerapan metode bercerita bagi kemampuan numerasi siswa usia dini dalam pembelajaran tematik. Metode penelitian yang digunakan adalah metode penelitian deskriptif kualitatif. Berdasarkan pemaparan hasil pembahasan ditemukan penerapan metode bercerita dilakukan dalam enam tahapan yang berkaitan erat dengan pengenalan kemampuan numerasi yaitu melakukan persiapan sebelum pembelajaran, mengecek kesiapan dan memberikan motivasi kepada siswa, melibatkan siswa secara aktif, bercerita dengan memperhatikan bahasa, melakukan pengembangan, dan mengecek pemahaman siswa. Melalui penerapan keenam tahapan metode bercerita dalam pembelajaran tematik dapat membantu guru untuk menilai serta mengkonfirmasi tingkatan kemampuan numerasi siswa usia dini.  Adapun saran selanjutnya adalah memperhatikan berbagai indikator kemampuan numerasi yang belum dikaji serta memerhatikan alokasi waktu dalam melakukan pengajaran sehingga keenam tahapan metode bercerita dapat dinilai keefektifannya.

Abstract

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.

Abstract

The activeness of students is important and fundamental to support the effectiveness of online mathematics learning. However, the reality shows that students often lack courage and enthusiastism in asking and answering questions, conveying understanding, and being less involved in doing assignments. Some of these indicate that students are less active in learning mathematics online. One of the efforts that teachers can make is through the application of various interactive media. Therefore, this paper aims to review and examine the implementation of various interactive media as an effort to stimulate the activeness of the students in online mathematics learning. Using descriptive qualitative research methods, it is evident that the implementation of various interactive media can enourage students to be active in online mathematics learning. The implementation of  various interactive media make students pay attention, so they can be encouraged to be actively involved in the learning process. Thus, students can be led to maximaze themselves in every opportunity to glorify God, including in the mathematics learning process. In the application of interactive media, teachers are advised to record every development of student responses for the improvement and development of interactive media.BAHASA INDONESIA ABSTRACT: Keaktifan siswa menjadi hal penting dan mendasar yang dapat menunjang keefektifan pembelajaran matematika secara daring. Namun, kenyataan menunjukkan bahwa siswa sering kurang berani dan antusias dalam bertanya, menjawab, menyampaikan pemahaman, serta kurang terlibat dalam mengerjakan tugas. Beberapa hal tersebut menunjukkan bahwa siswa kurang aktif dalam pembelajaran matematika secara daring. Salah satu upaya yang dapat dilakukan guru dalam mendorong keaktifan siswa adalah melalui penerapan media interaktif yang bervariasi. Olehnya tulisan ini bertujuan meninjau dan mengkaji penerapan media interaktif sebagai upaya yang dapat menstimulus keaktifan siswa pada pembelajaran matematika secara daring. Melalui metode kualitatif deskriptif, diketahui bahwa penerapan media interaktif yang bervariasi dapat mendorong siswa menjadi aktif dalam pembelajaran matematika secara daring. Media interaktif yang bervariasi menarik perhatian siswa sehingga mendorong siswa terlibat aktif dalam pembelajaran. Dengan demikian, siswa dapat dituntun untuk memaksimalkan diri dalam setiap kesempatan untuk memuliakan Allah, termasuk dalam pembelajaran matematika. Dalam penerapan media interaktif, guru disarankan mencatat setiap perkembangan respon siswa guna perbaikan dan pengembangan media interaktif.

Abstract

The number theory is the first mathematics content course in the UPH FIP Mathematics Education study program, which does not have a response class. The response class was conducted as a companion to four content subjects with close relations with school mathematics content, namely Calculus 1, Calculus 2, Geometry, and Linear Algebra. Based on the questionnaire that has been distributed, prospective mathematics teachers consider that the response class is beneficial for them in attending lectures and in exploring related mathematical concepts. However, on the other hand, students inevitably have to go back to learning to be determined with the response class. The implication is that students' self-regulated learning will not develop optimally. However, self-regulated learning is an essential aspect that prospective teachers need to have. This research was conducted to see how self-regulated learning of future mathematics teachers in number theory courses. The research instruments used are questionnaires, the scale of self-regulated learning, and interviews. This research is a qualitative descriptive study. The results of this study are that most students have a moderate level of learning independence. The aspects or indicators of learning independence that need special attention are setting learning goals/targets. Prospective teacher students need to continue to train and develop their learning independence to become professional teachers who continue to develop along with the times.
