An Analysis on the Need for Cooperative Learning Model with RME Approach for Mathematics Learning of Elementary School

Mathematics learning can stimulate the students to think critically and logically for the problem related to the real life. The initiation to mathematics learning for the first time at elementary. The aim of the research was to find out the need for cooperative learning model with Realistic Mathematics Education (RME) approach for mathematics learning in elementary school. This research was performed by descriptive qualitative approaches. The subject of research involved teacher and student respondents in the fifth grade of elementary schools in Karangpandan Sub District. An interview was performed to gain information from teachers and students. This techniques can reveal the implementation of mathematics learning in the classroom, also as a documentation to find out the mathematics learning outcome of students. This research suggested that cooperative learning model with RME approach can be used to improving the students’ mathematics learning outcome. Due to some reasons: (1) most of the teacher still using conventional learning model; (2) students involvement in mathematics learning was still low, and (3) teachers didnt connect mathematics learning to students’ real-life context. Keywords—mathematics learning; cooperative learning; RME approach.

Learning Obstacle Analysis of Indonesian Primary Students on Rectangular Concept and its Altenative Solutions

This study was aimed at analyzing students’ learning obstacles and mistakes in mathematical answers on the concept of rectangle. The study involved 28 junior high school students in Surakarta, Central Java, using a quantitative method. Based on the results of data analysis, 5 types of students’xa0 learning obstacles based on their answers were identified including variation of information context, concept image, relationship between rectangle’s area and its width, student’s ability to cope with questions, and relation between one concept to another. The alternative to overcome thelearning obstacles and mistakes in mathematical answers was by applying a didactic design which consisted of lesson plans, students’ worksheet as well as prediction of response and didactic anticipation. Keywords: Learning obstacles, mistakes in mathematical answers, didactic design. Tujuan penelitian ini adalah menganalisis hambatan belajar dan kesalahan jawaban matematika siswa pada konsep bangun segiempat. Penelitian ini melibatkan 28 siswa salah satu Sekolah Menengah Pertama (SMP) di Surakarta, Jawa Tengah, dengan menggunakan metode deskriptif kualitatif. Berdasarkan hasil analisis data, terindentifikasi 5 tipe hambatan belajar berdasarkan indikator kesalahan jawaban matematika siswa yaitu tipe konteks variasi informasi, concept image, hubungan keliling dan luas segiempat, kemampuan siswa dalam menyelesaikan soal soal, dan koneksi antar xa0konsep. Alternatif untuk mengatasi hambatan belajar yang menyebabkan kesalahanxa0 jawaban xa0tersebut, salah satunya yaitu dengan menerapkan desain didaktik yang terdirixa0 dari xa0RPP, lembar kerja siswa serta prediksi respons dan antisipasi xa0didaktik. Kata Kunci: Hambatan belajar, kesalahan jawaban matematika, desain didaktik. DOI:xa0 http://dx.doi.org/10.23960/jpp.v8.i1.201803
