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

This research is motivated by the learning results of learners on the material of building flat side space that is still low. This research was conducted to improve learners' learning outcomes on flat-sided room building materials through jigsaw-type cooperative learning models in class VIII SMP Negeri 9 Kei Kecil. This type of research is a class action study (PTK) consisting of two cycles with each cycle consisting of two meetings. The subjects in this study were class VIII learners with a sample of 15 learners. The data collection techniques in this study are observations and tests. Cycle I results in as much as 60% of learners reach KKM and do not meet the classic completion of 65%. The results of cycle II showed an increase of 86.67% of learners reaching KKM and fulfilling classical completion of 65%. Based on the results obtained, it can be concluded that using a jigsaw-type cooperative learning model can improve the learning outcomes of students of class VIII of SMP Negeri 9 Kei Kecil
