Abstract

Tesis ini berjudul ”Pengembangan Soal Matematika Model PISA pada Konten Quantity Untuk Mengukur Kemampuan Penalaran Matematis Siswa Sekolah Menengah Pertama”. Rumusan Masalah yang diteliti dalam penelitian ini adalah Bagaimana mengembangkan soal matematika SMP model PISA pada konten Quantity untuk mengukur kemampuan penalaran matematis siswa kelas IX yang valid dan praktis? Dan bagaimana efek potensial soal matematika model PISA pada konten Quantity untuk mengukur kemampuan penalaran matematis siswa kelas IX SMP Negeri 1 Lubuklinggau? Penelitian dalam tesis ini mengembangkan soal model PISA pada konten Quantity yang berfokus pada kebutuhan untuk kuantifikasi. Aspek penting meliputi pemahaman ukuran relatif, pengakuan pola numerik, dan kemampuan untuk menggunakan angka untuk mewakili atribut kuantitatif objek dunia nyata. Soal didesain berdasarkan framework soal PISA dan diadaptasikan dengan kurikulum KTSP yang digunakan di SMPN 1 Lubuklinggau dengan memperhatikan indikator penalaran matematis. Soal dikembangkan dalam dua tahap dua tahap yaitu preliminary dan tahap formatif evaluation yang meliputi self evaluation, expert reviews dan one-to-one (low resistance to revision) dan small group serta field test (hight resistance in revision). Adapun instrumen dalam penelitian ini adalah soal model PISA pada konten Quantity dengan teknik pengumpulan data berdasarkan walkthrough, dan analisis dokumen. Setelah melalui tahap one-to-one, small group dan validasi secara deskriptif kuantitatif, soal diujicobakan pada tahp field test di kelas IX 4 SMPN 1 Lubuklinggau. Hasil tes secara keseluruhan dengan nilai rata-rat kemampuan penalaran matematis 30,43, termasuk pada kategori kemampuan penalaran matematis yang cukup, walaupun masih ada beberapa siswa yang masuk pada kategori kurang. Terlihat bahwa kemampuan penalaran matematis siswa dalam menyelesaikan soal model PISA pada konten Quantity masih belum begitu baik. Hanya sebagian siswa saya yang bisa menggunakan kemampuan penalaran matematisnya untuk menyelesaikan smasalah yang diberikan pada soal tersebut. Namun dari hasil ini juga dapat dikatakan bahwa soal model PISA pada konten Quantity telah memiliki efek potensial terhadap kemampuan penalaran matematis siswa. Kata kunci: Soal matematika, PISA, Quantity, Kemampuan penalaran.

Abstract

Learning about decimals is an important part in mathematics. However at the same time, decimals are known as the  abstract numbers for students. Mostly in Indonesia, decimal is taught only as another notation for fractions or percentages. There are no meaningful references  for  them  such as  the  use of  concrete  situations. This study aimed at investigating one situation that enables students to learn about decimals in a meaningful way,  i.e.  measurement  activities.  Design research was chosen to reach the research goal. Realistic Mathematics Education (RME) underlies  the design  of  context and activities. Our findings are that the students could discover decimals and  get meaningful situation from it. Measurement activities can promote the students’ notion of decimals which, then, provoke the students’ thinking into the idea of using number line as a model for placing the magnitude of decimals. Based on these findings, it is recommended that RME be implemented as an approach of teaching and learning decimals.Keywords: decimals, Realistic Mathematics Education (RME), number line, design research. DOI: http://dx.doi.org/10.22342/jme.2.2.750.215-230

Abstract

Many prior researches found that most of students in grade five tended to have difficulty in fully grasping the concept of volume measurement because they have to build their competence in spatial structuring. The unit of volume packing measurement must be integrated and coordinated in three-dimension. On the other hand, it is revealed the errors that students made on the volume measurement tasks with threedimensional cube arrays are related to some aspects of spatial visualization, such as the skill to "read off" two-dimensional representation of solid objects. For those reasons, this research is aimed to develop classroom activities with the use of spatial visualization tasks to support students' spatial structuring in learning volume measurement. Consequently, design research was chosen as an appropriate means to achieve this research goal. In this research, a sequence of instructional activities is designed and developed based on the hypothesis of students' learning processes. This research was conducted in grade 5 of SD Pupuk Sriwijaya Palembang, Indonesia.Keywords: volume measurement, spatial structuring, spatial visualization, design research.

Abstract

Many researchers found that students have difficulties in understanding area measurement. Students mostly focus on applying formula to find the area of certain shapes without knowing what the area is and why the formula works. It is important for the students to know what attribute being measured and to construct the unit for area measurement. Therefore, the aim of this research is to develop activities that support students to know the attribute of area and the notion of measurement unit in learning area measurement. For this purpose, design research is chosen for achieving the research goal. Realistic Mathematics Education (RME) underlies the design of context and activities. A teacher and students in grade 3 in elementary school (SDN 21) in Palembang Indonesia will be involved in this research.Keywords: Area measurement, unit, design research, RME

Abstract

Usually, multiplication is introduced to students to represent quantities that come in group. However there is also rectangular array model which is also related to multiplication. Barmby et al (2009) has shown that the rectangular model such as array representations encourage students to develop their thinking about multiplication as a binary operation with row and column representing two inputs. Considering that finding, this study focusses on a design research that was conducted in Indonesia in which I investigate second grade students’ (between 7 and 8 years old) in Madrasah Ibtidaiyah Negeri (MIN) 2 Palembang, Indonesia, ability to structuring the situation and their ability to represent rectangular model into multiplication sentence. The results shows us that students activity to structuring the situation, looking the number of objects in row or in column, lead them to repeated addition and transform it into multiplication sentence.Keywords: Rectangular pattern, Multiplication DOI: http://dx.doi.org/10.22342/jme.2.2.747.185-198
