Abstract

Penelitian ini dilatarbelakangi pentingnya Kemampuan Berpikir Reflektif Matematis (KBRM) Kemampuan tersebut mendukung keberhasilan dalam kemampuan berpikir kritis dan kemampuan lainnya seperti menyelesaikan permasalahan dalam matematika. Tahapan KBRM berguna untuk mengetahui sampai jenjang mana seseorang sudah mencapainya. Bahan ajar juga menunjang untuk peningkatan KBRM, dengan demikian pada penelitian ini akan dikembangkan bahan ajar untuk meningkatan tahapan kemampuan berpikir reflektif matematis. Dengan demikian, target khusus penelitian ini adalah mendapatkan bahan ajar yang mendukung peningkatan tahapan KBRM. Metode yang  dilakukan untuk mengembangkan bahan ajar KBRM adalah penelitian pengembangan. Kegiatan pengembangan bahan ajar tahapan KBRM meliputi 1) analisis kebutuhan, 2) pengembangan produk, 3) validasi desain dengan uji ahli, 4) revisi desain, dan 5) uji coba skala kecil. Subyek penelitian ini adalah siswa SMA di Kota Serang. Hasil yang sudah diperoleh adalah bahan ajar cetak berupa lembar kerja siswa yang sesuai 7 tahapan KBRM yang berisi judul, materi, indikator, soal KBRM, panduan pertanyaan meningkatkan  KBRM.

Abstract

ABSTRACTThis research is motivated by the lack of ability of student teachers of mathematics FKIP University of Sultan Ageng Tirtayasa in developing worksheets and media exploratory hands on activity. Based on observations in the course clump of learning (planning, strategies and evaluation) and the implementation of microteaching done by the students, obtained the fact that students in developing a worksheet is a collection of questions and do not require the capability of understanding the concept of the student. In addition, student teachers are still rarely use the media in learning, due to difficulties in designing and creating instructional media. Hence the need for teaching material that can be used as guides student teachers to develop explorative and media worksheet hands on activity. Thus the formulation of the problem and the purpose of this study is how to develop teaching material based worksheets and media exploratory hands on activity. The method used in this research is the development method includes preliminary studies, draft development, testing and development of the final product.The results of this research is a module consisting of four units, units of learning theory, the difference unit worksheets and job sheets, media unit hands on activity and worksheet exploratory unit. In each unit consists of several sub-units that correspond to the unit. Based on the results of expert testing and limited trials showed that the worksheet-based development modules exploratory and hands on activity worthy of media used. Keywords: Teaching Material, Worksheet Explorative, Media Hands on Activuty

Abstract

The ability of mathematical reflective thinking is the ability to interpret a case based on the mathematical concepts involved, can evaluate the truth of an argument, can draw analogies from two similar cases, can analyze and clarify questions and answers, can generalize, and can distinguish between relevant data and not relevant. This ability is one of the high-level thinking skills that can be optimized through integrated learning in everyday life, namely learning with Environmental Based Problem Based Learning. To find out, a quasi-experimental study was conducted which aimed to find out the improvement of mathematical reflective thinking skills in terms of the high, medium and low mathematical abilities of the group. The subject of the research was class XI in SMA Negeri 1 Cilegon which was selected by cluster random sampling in the sequence and series material. The results of the data analysis showed that the Environmental Based Problem Based Learning model was better than the expository learning in improving the achievement and improvement of students' mathematical reflective thinking skills both viewed as a whole and viewed from the initial high, medium and low mathematical abilities. Keywords: Ability Of Mathematical Reflective Thinking, Environment-Based Problem Based Learning

Abstract

The purpose of this study was to produce interactive mathematics teaching materials with metacognitive scaffolding for students' thinking and mathematical reflective dispositions. This interactive teaching material is made in exetable windows (exe) format. The use of teaching materials is flexible with exe format so that it can be used on Windows-based computers. Exe is a type of file used to install or install applications based on a Windows operating system. This research is motivated by the weakness of students 'metacognitive abilities, and the small amount of teaching materials to develop interactive teaching materials with the ability of metacognitive scaffolding aspects, students' thinking abilities and mathematical reflective dispositions. This study uses a research and development design that contains 10 potential steps and problems, combining data, product design, design validation, revision design, product testing, product revision, usage testing, product revision and mass production. The results showed that the general interactive teaching material with metacognitive scaffolding for the ability and disposition of mathematical reflective thinking students had a very good classification with a contribution of 87.5% for education experts and 85.7% for mathematicians looking at resources Introduction, eligibility, presentation , and language. While for multimedia experts have 70%. Based on the results of expert tests and limited trials conducted on 10 grade VIII junior high school students in one of the junior high schools in the attack district it is undeniably related to interactive teaching materials with metacognitive scaffolding for support and 6% mathematical reflective. Keywords:  Interactive Teaching Materials, Scaffolding, Metacognitive, Reflective Thinking, Mathematical Disposition
