Abstract

Pendidikan merupakan sebuah proses kegiatan yang di sengaja atas input siswa untuk menimbulkan suatu hasil yang diinginkan sesuai tujuan yang ditetapkan. Pendidikan matematika perlu ditingkatkan kualitasnya. Banyak persoalan kehidupan yang memerlukan kemampuan menghitung dan mengukur. Terobosan efektif untuk membangkitkan semangat belajar dan hasil belajar siswa disekolah salah satunya dengan membangun komunitas belajar. Tujuan penelitian ini adalah untuk mendeskripsikan Efektivitas Komunitas Belajar Siswa Kelas VII Pada Materi Segiempat. Subjek dalam penelitian ini adalah siswa kelas VII SMPN 2 Ngadiluwih Kediri dan peneliti bertindak sebagai guru dalam melaksanakan pembelajaran. Jenis penelitian ini adalah kuantitatif deskriptif. Instrumen yang digunakan adalah lembar observasi kemampuan guru, lembar observasi aktivitas siswa, lembar tes hasil belajar, dan lembar angket respon siswa. Pada penulisan ini hanya akan menyajikan samapai pembuatan instrumen yang akan digunakan untuk penelitian.

Abstract

Spatial thinking is a basic skill that can be accessed by everyone to different degrees in different contexts to solve problems in a variety of contexts. To think spatially related needs three components, namely: the concept of space, methods of spatial representation, and spatial reasoning. Some areas of mathematical problem solving related to spatial thinking. One of them is geometry. There are two standards that are used to study the geometry and both relate to the spatial. In resolving the problem geometry everyone has their own way. How is exactly what is called a learning style. The purpose of this study was to determine the students thinking process in solving the problems of spatial geometry of each learning style. This study is a qualitative research diskriptip. the students selected as the sample under consideration from teachers. Then visits the last student learning outcomes and then classified into 3 groups: high, medium and low. After the selected student groups are to be given a learning styles test. Then have one student who has a visual learning style, one students learning style and one students auditory kinesthetic learning style. The third sample will be given the test geometry indicator is adjusted to think spatially. Then Through in-depth interviews will be obtained on individual profiles in solving geometry problems. Along with interviews, researchers will observe the activity of students. Then the data obtained will be analyzed just not comparable between learning styles. So the instrument in this study is about, observation sheet and interview.

Abstract

Quantitative Reasoning is students ability to concluded a problem solved. The purpose of this research has information about algebraic thinking processed on the student with low ability based on Quantitative Reasoning ability. Methods used qualitative descriptive with a purpose for a description of algebraic thinking processed on mathematics problem solving basic material on function with the low ability of student based on quantitative reasoning ability. This paper used algebraic ability paper test and interview transcript. The subject cluster used purposive technic with appreciation high value on report and teacher review which are known about students characteristic. The results showed that algebraic thinking processed on mathematics problem solving on the student with low ability based on quantitative reasoning ability obtained LESS category because the subject doesn’t capable used deductive reasoning on clarifying n symbol on problem and representation on arrow diagram and Cartesian diagram for the first problem test. With the result that Quantitative Reasoning subject on analyzing problems to extract and quantify essential features with deductive reasoning obtained “Less” category. The second problem test, the subject doesn’t capable used inductive reasoning on concluding highest bounce of the ball from the graphic and function table. With that result that Quantitative Reasoning subject on analyzing problems to extract and quantify essential features with inductive reasoning obtained “Less” category.

Abstract

Geometry is one of school material subject which close with our daily activities. They used geometry form concept to interior and exterior design. The closeness between geometry content and daily activities encourage author to explore how is spatial thinking elementary student. Two kinds of representations are internal representation and external representation. Representation internal include perception, distortion or abstraction and relationships between objects, external representation reveal the product of thought to image, words, table, concrete object, or mathematic symbols used to understand  yourself and others.Transformation is representation component. Transformation needs object to operate it, and representation needs transformation to create representation. Transformation is tool to descript representations.Subject of the research is elementary school students grade 5th, the researcher gives them a problem of geometry object 2 dimensions to 3 dimensions The research findings are the subject be able to construct a genetic definition of  the cube by using analogical thinking in the preparation of  the definition.

Abstract

Abstrak: Tujuan tulisan ini adalah menuliskan laporan rekam jejak pembuatan video animasi 3D Portofolio tahap define dan design. Pengembangan perangkat pembelajaran berbasis video 3D portofolio yang digunakan dalam penelitian pengembangan perangkat ini adalah menggunakan teori pengembangan perangkat pembelajaran Thiagarajan (Thiagarajan, Semmel dan Semmel, 1974: 5) yang dikenal dengan Four - D Model atau model 4-D. Model ini terdiri atas empat tahap, yaitu: Define (pendefinisian), Design (perencaaan), Develop (pengembangan), dan Desseminate (pendiseminasian). Adapun alasan penulis memilih model pengembangan Thiagarajan untuk dipakai dalam penelitian ini karena model tersebut terperinci dan sistematis sehingga memudahkan dalam melakukan proses pengembangan perangkat dan instrumen. Namun demikian model tersebut dimodifikasi sehingga yang digunakan dalam penelitian ini hanya memuat: Define, Design, dan Develop. Modifikasi yang dilakukan meliputi: 1) analisis tugas dilakukan setelah analisis konsep/topik, 2) perancangan awal didahului oleh perancangan instrumen, dan 3) penyederhanaan langkah-langkah pada tahap pengembangan (develop).Ada 3 tahapan pembuatan video animasi 3 dimensi Portofolio yaitu menggambar sketsa 2 dimensi dengan menggunakan program autocad dan google sketchup, merender gambar 2 dimensi ke 3 dimensi dengan menggunakan program lumion dan mengedit video dengan menggunakan adobe after effect.

Abstract

Abstrak: Rendahnya hasil PISA dan TIMSS siswa Indonesia kontradiktif dengan motivasi belajar matematika dan sains mereka yang berada di atas Singapura dan Malaysia. Permasalahan tersebut dikarenakan kurangnya MCK khususnya domain penalaran di setiap Mathematical Content. Mereka perlu penguatan kemampuan mengintegrasikan informasi, menarik kesimpulan, serta menggeneralisasikan pengetahuan yang dimiliki.  Untuk itu dilakukan penelitian pengembangan yang bertujuan menghasilkan Buku Kerja Siswa (BKS) yang valid, praktis dan memiliki efek potensial bagi literasi matematika siswa SMP. Penelitian ini mengacu pada modifikasi model 4-D Thiagarajan yaitu Define, Design dan  Develop.  Prosedur penelitiannya adalah: 1) menganalisis MCK awal siswa SMP di Kota Kediri berdasarkan domain TIMSS dan literasi matematika PISA; 2) mengembangkan BKS yang valid, praktis dan layak.  Hasil penelitian menunjukkan BKS yang dikembangkan termasuk dalam kriteria sangat layak, ditinjau dari kelayakan isi sebesar 84,11%, kelayakan bahasa sebesar 86,61%, kelayakan kegrafikan sebesar 84,72% dan Hasil ujicoba terbatas pada tiga puluh orang siswa mendapat respon positif sebesar 98,25%.   Kata Kunci: BKS, MCK, Literasi Matematika, Siswa SMP
