Abstract: The goal of teaching problem solving in mathematics is to develop students ability in monitoring and evaluating their  owns thinking process. Such ability represent the part of mental activity which called metacognition. The process of problem solving happened by interaction among cognition and metacognition activity, where this interaction can be shown in a level of awareness is called by the level  of metacognition. By analysing the characteristic of students metacognition when they solved  mathematics problem, and compare it with the indicators of every metacognitions level, then empirical we can find the characteristics  of the metacognitions level.

Education in the present has become a necessity, the need for knowledge gained through the learning process both in school and learning from the environment of residence. Mathematical skills are important for everyday life, when students work in activities that are based on everyday life situations; they see ways of applying the mathematical skills they are learning to the real world. Thelearning strategy REACT is one of the learning strategies that use the environment as a source of learning. Besides the teaching learning process with active student learning methods (CBSA) the teacher must be more active in preparing lesson material, planning the process to be carried out such as RPP, preparing evaluation such as LKS and follow-up. From the results of the study the development of learning tools for student activities reached 91.25% and the success rate of students reached 70%. Thus the development of a square and rectangular learning device using theREACTstrategy has a good effect on student activity and student learning outcomes

An Integer is one material that is still considered difficult by students, even junior and senior high school students. Therefore it is necessary to prepare a learning media that can help students to master integers well. Various media have been developed to make it easier for students to understand and operate integers. However, the media is still far from the reach of students. This study aims to develop learning media for integers based on local Maluku wisdom as well as learning tools, namely the Lesson Plan, teaching materials, and student worksheets that serve as a guide in learning. This research is development research using the ADDIE development model, which consists of stages, namely: Analysis, Design, Development, Implementation, and Evaluation. The research begins by analyzing the students' abilities on integer material and teaching materials and the media used in learning. Then the researcher designed the media and learning tools which were then submitted to the experts to be validated and to students for their implementation. Based on the results of the validation of experts and student learning outcomes, it can be concluded that the resulting learning tools are valid and can be used

Matematika yang diajarkan di sekolah dikenal dengan matematika sekolah yang kajian materinya disesuaikan dengan perkembangan kognitf kebutuhaan peserta didik. Matematika tidak hanya dipelajari di sekolah tetapi sebenarnya matematika secara tidak langsung telah dikenal sebelumnya dalam lingkungan masyarakat. Secara tidak langsung masyarakat telah mengenal matematika dalam aktifitas keseharian mereka misalnya menghitung, mengukur bahkan menghasilkan produk misalnya anyaman. Kebiasaan ini merupakan budaya yang dapat dikaitkan dengan konsep matematika yang lebih dikenal dengan istilah etnomatematika. Penelitian ini bertujuan mengkaji etnomatematika dalam masyarakat Maluku yang dapat diterapkan dalam pembelajaran matematika sekolah. Hasil penelitian menunjukkan bahwa konsep matematika yang dapat dieksplorasi dalam budaya masyarakat Maluku adalah konsep bilangan khususnya pecahan, nilai tempat, dan geometri khusunya pengubinan. Dengan cara berjualan masyarakat yang mengelompokkan objek jualan dalam bentuk tumpukan-tumpukan kecil misalnya berjualan buah-buahan seperti langsat dan manggis, makan tradisional seperti embal dan sagu lempeng dapat ditanamkan konsep pecahan, pecahan senilai dan urutan pecahan. Selain itu dalam pembuatan pembungkus makanan khas “kuyabu” maupun “suami” digunakan daun yang dibuat berbentuk kerucut. Dengan mengaitkan budaya dalam menanamkan konsep pecahan pada siswa kelas 4 SD Negeri Teladan menunjukkan peningkatan pemahaman peserta didik terhadap konsep tersebut yang ditunjukkan dengan tingginya nilai gain score yaitu 0.57. Dampak pengiring lainnya adalah pemahaman peserta didik terhadap makanan khas daerah yang secara tidak langsung menumbuhkan karakter cinta tanah air. Kata kunci: Etnomatematika, pembelajaran matematika

This study aims to describe the thinking process of students in solving mathematical problems of triangular and quadrilateral material in terms of cognitive style. The thinking process in this study is the steps taken by students involving mental activities in solving problems related to problem solving. The process of thinking in this study there are three kinds, namely conceptual thinking, semi-conceptual thinking and computational thinking. This research is a qualitative descriptive study. The subjects in this study were grade VII students consisting of four students with details of each two students from the Field Independent (FI) cognitive style and two students from the Field Dependent cognitive style (FD). Data collection techniques used in this study were mathematical tests and interviews. Data on the results of mathematical tests and interviews were analyzed based on indicators suitable with the conceptual thinking process, semi-conceptual thinking process and computational thinking process. From the results of data analysis, it was found that the students' thinking processes in solving mathematical story problems in the Field Independent group is the conceptual and semi-conceptual thinking processes. And students' thinking processes in solving mathematical story problems in the Field Dependent group tend to be semi-conceptual and computational thinking processes.
