Abstract

Abstract: The goal of teaching problem solving in mathematics is to develop student’s ability in monitoring and evaluating their  own’s 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 student’s metacognition when they solved  mathematics problem, and compare it with the indicators of every metacognition’s level, then empirical we can find the characteristics  of the metacognition’s level.

Abstract

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

Abstract

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

Abstract

This study aims to determine the characteristics of students' metacognition in solving mathematical literacy problems. The metacognitive traits explored are related to awareness in planning, monitoring, and evaluating the design of the thinking process used. The research method used is a mixed-method (sequential explanatory), which uses quantitative research results to conduct qualitative research. The research subjects were 80 early semester students who took the literacy test and chose six respondents representing the upper, middle, and lower groups, with two people in each group to be interviewed. The results showed that the mathematical literacy skills of prospective teachers were at a low level. Metacognitive characteristics that appear in the low group are (1) realizing that the solution of strategy is not right but not improved; (2) planning to develop a settlement strategy, but are not sure, (3) do not carry out the re-check process, and (4) do not believe what is being thought and do not understand the concept. Metacognitive traits in the middle group are (1) aware of what they are thinking, (2) consciously plan various strategies to improve thinking accuracy, but do not always use these strategies, (3) tend to monitor the thinking process, and (4) show tendency to master the basic mathematical concepts of the problems at hand.The characteristics of metacognition in the high group during problem-solving are (1) Using various strategies to demonstrate or improve the accuracy of thinking (sketching, drawing), (2) Analyzing the problem before solving it, and (3)Understanding and mastering the mathematical concepts that underlie the problem which is given.

Abstract

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

Abstract

Ethnomatemics-based mathematics concept implementation can be carried out through constructivism-based learning such as realistic mathematics, problem-based and learning with a scientific approach. This research purpose to explore the form of ethnomatemics on the woven cabbage leaves of the Tutuwaru community and analyze the process of understanding mathematics from the perspective of indigenous people and indigenous knowledge and examine the development of woven form ethnomatatics in school mathematics. The method used in this research is descriptive qualitative research. The subjects are 2 members of the weaving community, while the objects of research are Nyiru (winnowing-basket), Topi (hat), Keranjang dan Bakul (basket). The results showed that the form of weaving from a typical local Koli (cabbage) tree, could be connected with several mathematical concepts such as basic geometry and arithmetic. The hexagonal concept based on the understanding of multiples is an "indegious knowledge" that exists in the Tutuwaru community in constructing the form of nyiru-woven, reflection, points, lines and tessellation. These mathematical ideas can be used as context in school mathematics learning

Abstract

The Covid-19 pandemic has changed the pattern of education. Especially with the Independent Learning Program, teachers are required to be creative and innovative, teachers must create a happy atmosphere in learning. One way is to develop learning media that makes students enthusiastic in learning online. Learning videos are audio-visual media as a teacher's tool in delivering material to make it easy for students to understand and the Canva application that can support learning materials to be more interesting. The purpose of this service is to improve the quality of teachers by developing learning media according to the independent learning program. This service is carried out offline at SD N 1 and 3 Waimital. The result of this training is that teachers are able to develop video-based learning media because it really helps clarify subject matter so that teachers can implement the Independent Learning Program
