Keterampilan berfikir tingkat tinggi penting diluaskan pada diri peserta didik, karena mereka memainkan peran penting dalam memahami masalah. Pembelajaran mengutamakan proses pemodelan matematika berdasarkan kondisi lingkungan siswa, sehingga pembelajaran Realistic Mathematics Education (RME) dapat mengembangkan daya pikir tingkat tinggi. Analsis ini merupakan tentang penelitian kualitatif interpretatif yaitu suatu studi yang datanya diberikan secara wajar atau apa adanya dengan menerapkan tata kerja yang terstuktur, terpaku dan dapat dipertanggungjawabkan agar tidak kehilangan sifat ilmiahnya. Adapun tujuan penelitian ini adalah untuk menginformasikan kepada pengajar atau pendidik bahwa dalam mengimplementasikan RME (Realistics Mathematic Education) dapat meningkatkan pola pikir murid sehingga meningkatkan keterampilan HOTS pada muatan bidang studi pada SD. Pola didalam analisis ini menggunakan metode mengidentifikasi, mengkaji, mengevaluasi, menginterpretasikan penelitan. Berdasarkan tinjauan pustaka, didasarkan pada beberapa indikator kemampuan berpikir siswa tinggi: interpretasi, analisis, evaluasi, dan penarikan kesimpulan. Selanjutnya, pengembangan beberapa langkah pembelajaran pendidikan matematika realistik (RME): persiapan, inisiasi, sistem proses pembelajaran, dan penyelesaian.

Tujuan dari tulisan ini adalah untuk membahas tetang model pembelajaran khususnya dalam pembelajaran matematika di sekolah menengah yang ditinjau dari sudut pandang filsafat pendidikan. Rumusan masalah dalam tulisan ini yakni bagaimana model pembelajaran matematika dalam perpesktif filsafat pendidikan ditinjau dari kajian aksiologi. Tulisan ini menggunakan kajian pustaka (library research), dengan pendekatan kualitatif. Adapun hasil pembahasan tulisan ini dapat disimpulkan : 1. Penerapan model pembelajaran di sekolah bertujuanÂ sebagai sarana bagi guru dan siswa dalam mencapai tujuan dari pembelajaran dan sebagai pedoman dalam pelaksanaan sintaks yang telah dirancang dengan tujuan agar pembelajaran menjadi terarah sampai pada tahap akhir pembelajaran. 2.Model pembelajaran sangat dibutuhkan dalam proses belajar mengajar di kelas karena dengan menerapkan model pembelajaran interaksi antara guru dan siswa menjadi bermakna artinya setiap proses yang dilakukan dalam kegiatan pembelajaran mendukung untuk tercapainya tujuan dari pembelajaran itu sendiri.3. Penerapan model pembelajaran dapat disesuaikan dengan sintaks pembelajaran yang berhubungan dengan karakteristik siswa dan materi pelajaran dimanaÂ dari hasil penelitian yang pernah dilakukan bahwa dalam penerapan model pembelajaran yang sesuai dapat meningkatkan kemampuan siswa dalam bermatematika khususnya dalam menyelesaikanÂ masalah-masalah kontekstual

This study aims to determine: (1) statistically test and analyze the problem-solving abilities of students taught by the Problem Based Learning model or not higher than students taught by the Group Investigation learning model; (2) statistically testing and analyzing the self-confidence of students who are taught by the Problem Based Learning model are higher or not than students who are taught by the Group Investigation learning model; (3) the interaction between learning models (PBL and GI) with early mathematical abilities (KAM) on students' problem-solving abilities; (4) the interaction between learning models (PBL and GI) with early mathematical abilities (KAM) on students' self-confidence abilities. This research is quasi-experimental. The population in this study consisted of all students of class X MA Ponpes Darul Quran totaling 210 students in the 2021/2022 academic year, taking samples of two classes totaling 70 students using the cluster random sampling technique. Data analysis was performed using a two-way analysis of variance (ANOVA). The results of this study indicate that: (1) The problem-solving abilities of students who are taught problem-based learning are higher than students who are taught by group investigation, and (2) the Self-Confidence of students who are taught problem-based learning is higher than students who are taught by group investigation. , (3) there is no interaction between the learning model and KAM on students' problem-solving abilities, and (4) there is no interaction between the learning model and KAM on students' self-confidence abilities.

The implementation of learning in the current situation can be carried out using online learning as part of the methodology to answer the educational challenges caused by the outbreak of the COVID-19 pandemic. The role of technology in the online learning process in previous research studies has made it a major and important factor for successful learning in this emergency situation. This study aimed to investigate a philosophical perspective using the critical realism paradigm regarding the role of technology in online learning practices based on e-learning systems and justice in social interaction in aspects of learning implementation during the COVID-19 pandemic. This was a qualitative method with a critical realism approach. The results indicated that several critical arguments exist to rebalance the role of technology back to its origin, which is not a major factor, but a factor that still requires support from personal factors, personal behavior, and teacher readiness in facing technological developments. The findings of the study can be used to implement technology-based online learning while keeping practical and social justice in mind for both students and teachers.

The purpose of the study was to analyze 11 studies related to mathematical learning according to the phase of solving the piaget theory, namely: (1) At the sensory stage, it was possible to coordinate the experiences of the senses with movement and gain an understanding of the permanent object (2) pre-operational, the students understood the realityWhile some students are not yet at the stage to use logical thinking or formal operational thinking, many participants have not been able to use concrete operations to form more complex operations. Thus it can be concluded that in the piaget stage, students often cannot face when solving mathematics and learning problems are in concrete operational and formal operational stages. Meanwhile, in the motor and pre-operational stages, students did not experience any obstacles. Therefore, it is hoped that further researchers can pay more attention to the stages of piaget theory in mathematical learning.

Abstract Quality education comes from the quality of the teachers. Especially the competence of teachers from the professional, pedagogical, moral, and social aspects. Competent teachers are seen from their performance results, while to realize quality performance, motivation is needed from the principal. This study aimed to look at the leadership attitude of school principals in improving the quality of education during the COVID-19 pandemic. This research uses quantitative methods. The sample was teachers at SDN 200212/2 Padangsidimpuan schools, and the sample was determined using a random sampling technique. They are collecting data using a questionnaire with a Likert measurement scale. Data analysis used descriptive statistics using the 2022 version of STATCAL software. The study results describe that the leadership attitude carried out by the principal of SDN 200212/2 Padangsidimpuan city, North Sumatra province is excellent at 93% based on responses from 20 teachers. Meanwhile, teachers who are in a neutral position see only 5% of the principal's leadership, and 2% of teachers think that the principal rarely rewards work performance. It is never fair to give sanctions to subordinates who fail to carry out their duties.
