Abstract

Penelitian ini bertujuan untuk mendeskripsikan perbedaan pengaruh pendekatan Pendidikan Matematika Realistik Indonesia (PMRI) dan pendekatan konvensional serta keefektifan pendekatan PMRI dan pendekatan konvensional ditinjau dari motivasi berprestasi, kemampuan pemecahan masalah, dan prestasi belajar siswa pada siswa kelas VIII SMP Negeri 1 Luragung. Penelitian ini merupakan penelitian eksperimen semu (quasi experiment). Populasi penelitian ini adalah seluruh siswa kelas VIII SMP Negeri 1 Luragung, semester ganjil tahun pelajaran 2013/2014 yang terdiri atas delapan kelas. Sampel dipilih sebanyak dua kelas dari 8 kelas dengan menggunakan teknik cluster sampling. Perbedaan pengaruh dianalisis menggunakan uji multivariat (MANOVA) dan keefektifan dianalisis dengan uji one sample t test dengan taraf signifikansi 0,05. Hasil penelitian menunjukkan bahwa terdapat perbedaan pengaruh yang signifikan antara pendekatan PMRI dan pendekatan konvensional ditinjau dari motivasi berprestasi, kemampuan pemecahan masalah, dan prestasi belajar siswa dan pendekatan PMRI efektif ditinjau dari motivasi berprestasi.Kata Kunci: Pendekatan Pembelajaran Matematika Realistik Indonesia, pendekatan konvensional, motivasi berprestasi, kemampuan pemecahan masalah, prestasi belajar. The Effect of the IRME Approach on the Achievement Motivation, Problem Solving Skills, and Learning Achievement AbstractThis study aimed to describe (1) Differentiation the effect of Indonesian Realistic Mathematics Education (IRME) and the conventional approach and (2) Effectiveness of IRME approach and the conventional approach on achievement motivation, problem solving skills, and learning achievement of the eighth grade students of SMP Negeri 1 Luragung. This study was a quasi-experimental study (quasi-experiment). The population of this research was all the eighth grade students of SMP Negeri 1 Luragung, semester I academic year 2013/2014 consisting of eight classes. Two classes was chosen from 8 classes by using cluster sampling technique as samples. The effect of IRME were analyzed using multivariate test (MANOVA), and effectiveness were analyzed using one sample t test with a significance level of 0.05. The results show that there is a significant difference effect between IRME approach and the conventional approach on achievement motivation, problem solving skills, and students learning achievement. IRME approach effective on achievement motivation in the subject system linear equations in two variables in SMP Negeri 1 Luragung.Keywords: Indonesian Realistic Mathematics Education (IRME) approach, the conventional approach, achievement motivation, problem solving skills, learning achievement.

Abstract

Tujuan penelitian ini adalah menghasilkan perangkat pembelajaran bangun ruang dengan pendekatan Creative Problem Solving  yang berkualitas baik berdasarkan kriteria valid, praktis, dan efektif. Jenis penelitian ini adalah penelitian dan pengembangan dengan model pengembangan Four-D yang diadaptasi dari Thiagarajan, Semmel, dan Semmel yang memuat tahap define, design, develop, dan disseminate. Penelitian ini menghasilkan perangkat pembelajaran yang terdiri dari Rencana Pelaksanaan Pembelajaran (RPP), Lembar Kegiatan Siswa (LKS), tes prestasi belajar, dan tes kemampuan penalaran matematis. Hasil validasi menunjukkan bahwa perangkat yang dikembangkan memiliki kategori sangat valid untuk masing-masing RPP, LKS, dan tes. Hasil uji coba menunjukkan bahwa RPP dan LKS yang dikembangkan memiliki kategori praktis dan efektif. Kepraktisan mencapai kategori sangat praktis berdasarkan penilaian guru dan mencapai kategori praktis berdasarkan hasil observasi keterlaksanaan pembelajaran dan penilaian siswa. Keefektifan mencapai kategori efektif berdasarkan ketuntasan belajar siswa. Secara klasikal ketuntasan tes prestasi belajar mencapai 76,67% dan tes kemampuan penalaran matematis mencapai 90%.Kata kunci: pengembangan, perangkat pembelajaran, Creative Problem Solving  Developing of Solid Instructional Package with Creative Problem Solving Approach AbstractThe aim of this research was to produce the solid instructional package with Creative Problem Solving  approach which have good quality based on the validity, practicality, and effectiveness criteria. This study was a research and development using the developmental model adapted from Thiagarajan, Semmel, and Semmel included define, design, develop, and disseminate stages. This study produces instructional package consists of lesson plans, student worksheets, achievement tests, and mathematical reasoning tests. The results of the validation showed that the developed package is very valid based on lesson plans, student worksheets, and tests. The results of the tryout indicated that lesson plans and student worksheets are practical and effective. The practicality was in  very practical category based on teacher’s assessment and practical category based on the implementation of learning and student’s assessment. The effectiveness was in the effective category based on student’s learning mastery. In the classical mastery learning it reached 76.67% for achievement and 90% for mathematical reasoning.   Keywords: development, instructional package, Creative Problem Solving

Abstract

This study aims to: (1) look for the highest and lowest values in number and algebraic material of Junior High School in East Lombok, (2) the percentage of errors made by students when answering math problems, and (3) the diagnosis of student’s misconception in doing number and algebra at Junior High School in East Lombok. This research is a quantitative- descriptive research. For the sampling technique, this study used purposive sampling. The test was conducted in five classes with 200 students as research participants. The sampling took into account the level of students’ ability and school readiness. The sampling size is 361 students from five schools. The data were in the form of students’ responses and those were analyzed using the Quest program. The results of this study are as follows. First, in terms of the difficulty index, 40 items (47%) are easy category items, 8% are medium category items, and 45% are difficult category items. Out of the 40 problems, 82% of the items have good difficulty index, while 18% are not good. Of the four alternative answers, 88% of the distractor is in a good category, and 12% are not good. Second, based on the students’ answers, the percentage of error is 52 %. Third, based on the result of the analysis using the Quest program, of the tow materials, the biggest misconception is in number with the percentage of 68%.
