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.

This research examines the effectiveness of Problem-Based Learning (PBL) in mathematics education through a systematic analysis of 27 research journals. The study focuses on the implementation of PBL in enhancing critical thinking abilities, problem-solving skills, mathematical literacy, as well as student motivation and learning outcomes. Meta-analysis results indicate that PBL has significant positive effects on critical thinking abilities in mathematics learning (g=0.769) and science (g=1.122). Comparative studies suggest that PBL is more effective than conventional learning in improving critical thinking skills and learning motivation. Several classroom action research studies report improvements in learning mastery and student mathematics achievement following PBL implementation. However, PBL implementation also faces challenges such as student passivity, teacher readiness, time management, and difficulties in achieving Higher Order Thinking Skills (HOTS) indicators. The development of PBL-based learning tools and interactive media shows promising results in enhancing learning effectiveness. This research concludes that PBL is an effective approach for developing higher-order thinking skills and conceptual understanding in mathematics, although its success depends on teacher readiness and adequate learning system support.

This research aimed to analyze undergraduate students’ mathematical creative thinking abilities (MCTA). This study employs a qualitative descriptive method, with the research subjects being Mathematics Education Study Program students. Tests and interviews were the instruments used for mathematical creative thinking ability. The results of the research show that students' mathematical creative thinking abilities vary, as many as 20% are in the low category (CCTA < 33%), 60% are in the medium category (CCTA between 33% and 67%) and 20% are in the high category (CCTA > 67 %). Understanding mathematical concepts, learning experiences, and motivation all have an impact on students creative mathematical thinking skills. It is hoped that the results of this research can be considered when designing learning that can develop students' mathematical creative thinking abilities. Keywords: analyze, mathematical creative thinking abilities, undergraduate students’

Program kemitraan masyarakat ini dilakukan pada tingkat sekolah dasar di desa medan estate. Kegiatan ini bertujuan untuk meningkatkan kompetensi guru dalam merancang dan menerapkan pembelajaran berbasis literasi numerasi dalam pembelajaran Bahasa inggris di sekolah dasar. Literasi numerasi didefinisikan sebagai kemampuan untuk menggunakan pemikirannya dalam menganalisis dan memahami suatu pernyataan melalui operasi memanipulasi simbol atau bahasa yang ditemukan di kehidupan sehari-hari dan dinyatakan secara tertulis dan lisan. Literasi merupakan keterampilan dasar yang membekali siswa dalam memilih dan menganalisis informasi penting. Sedangkan numerasi adalah keterampilan dasar yang memberikan siswa bekal untuk menerapkan konsep bilangan dan operasi dalam kehidupan sehari-hari. Namun pada kenyataanya, guru belum juga memahami mengenai konsep dasar dari literasi dan numerasi pada pembelajaran Bahasa inggris di sekolah dasar. Pembelajaran belum meningkatkan kemampuan siswa dalam berbahasa. Oleh karena itu, melalui kegiatan ini diharapkan guru dapat meningkatkan keterampilannya dengan menjadi guru yang lebih kompeten dalam menerapkan pembelajaran berbasis pada literasi numerasi yang menarik dan sesuai tingkat sekolah dasar dengan. Selain itu, juga diharapkan guru termotivasi untuk terus mengembangkan pembelajaran sesuai topik yang terus berkembang sesuai dengan daerah setempat.
