Abstract

This research aims to produce development products and determine the feasibility of student activity based on challenge based learning worksheet opportunities material in grade 8 at SMP Negeri 5 Pangkalpinang. This research is a development research through two stages, first the preliminary stage consist of preparation and design. The Second is formative evaluation stage consist of self-evaluation, expert reviews, one-to-one, small group, and field test. This research produce Challenge Based Learning worksheet in opportunities material and sample consist of 38 students. The technique of collecting data by observation sheets, questionnaires, tests, and documentation. The data is analyzed so that the resulting instrument is valid and practical. Valid is described based on the validator's assessment in terms of content, construct, and language. Practicality is illustrated by the trial results at the small group stage. From the results of data analysis, the feasibility of the contents of the 3.55 categories is very good, the feasibility of serving 3.65 categories is very good, and the language feasibility is 3.12 categories are good. From the research results have produced LKS based challenge based learning on opportunity material.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan penalaran matematis siswa dalam mengerjakan soal matematika pada buku pembelajaran tematik bakul berkisah. Penelitian ini dilatarbelakangi oleh rendahnya hasil nilai TIMSS siswa Indonesia pada ranah penalaran (reasoning) dan belum ada buku tematik yang dapat melatih penalaran siswa. Penelitian ini merupakan penelitian deskriptif kualitatif yang dilakukan terhadap 33 siswa kelas III SD Muhammadiyah Pangkalpinang. Pengumpulan data didapat dari hasil jawaban dan pengamatan siswa dalam mengerjakan soal-soal matematika pada buku tematik bakul berkisah materi penjumlahan dan pengurangan. Kemudian jawaban dianalisis untuk melihat penalarann matematis siswa. Terdapat enam buah indikator penalaran matematis yang dilihat dalam penelitian ini. Indikator penalaran yang paling tinggi dilakukan oleh siswa adalah menarik kesimpulan,dengan kata lain siswa dapat menemukan jawaban dengan benar. Sementara siswa masih kesulitan dalam menemukan pola atau sifat dari gejala matematis untuk membuat generalisasi. Hal ini sebetulnya disebabkan karena siswa belum terbiasa mengerjakan soal lengkap dalam setiap pengerjaan. Namun rerata hasil penalaran matematis siswa adalah 68,18% dan dikategorikan baik. Hasil penelitian yang didapatkan menunjukkan bahwa pembelajaran matematika menggunakan buku tematik bakul berkisah, sudah baik dalam memacu penalaran matematis siswa. AbstractThis research aims to describe the mathematical reasoning’s students doing math problems in the bakul berkisah thematic book. This research because of the low result of Indonesian students in TIMSS score especially for reasoning and there aren’t thematic book in their school. This research is a qualitative descriptive research with 33 student for sample. The data collection from the answer of student thematic book and observing of student learning in addition and subtraction material. The answer student is analyzed the student's reasoning.  There are six indicators of mathematical reasoning ability. The highest reasoning indicator is drawing conclusions or can find answers correctly. While students still have difficulty in finding patterns or properties of mathematical phenomena to make generalizations. This is actually because students are not used to working on complete questions in each work. However, the average result of students' mathematical reasoning is 68.18% and it is categorized as good. The results of the research showed that learning mathematics using the thematic book based was good in students' mathematical reasoning.
