Abstract

This study aims to: (1) find out the significant differences of students’ math reasoning abilities with the Discovery Learning model, Connected Mathematics Project (CMP) learning model, and conventional learning models; (2) find out which one of the above models are considered as the better model. This study was a quasi-experimental with the population from eighth grade students of SMPN 6 Bengkulu city and took sample from three classes namely VIII-D as the experimental class 1, class VIII-E as the experimental class 2, and class VIII-F as the control class.The technique for collecting data used a test of mathematics reasoning ability and analyzed by using one-way ANOVA test and continued with LSD test. Based on the result of study there were significat differences in students’ math reasoning abilities by using Discovery Learning, Connected Mathematics Project (CMP) and the conventional learning models.From the BNT test was obtained that Connected Mathematics Project (CMP) learning model gives the better results of students’ mathematics reasoning abilities than the Discovery Learning and Conventional learning models. Keywords: Reasoning Ability, Discovery Learning, CMP

Abstract

Mathematical creative thinking ability is the ability of students in generating new ideas to solve mathematical problems. To develop mathematical creative thinking abilities of students, teachers must have and implement a learning model that fits in the learning process. Learning model that can be used to measure students' ability to think creatively mathematical namely the model of inquiry learning and teaching model . This study aims to determine whether the inquiry learning model in individually and together better than conventional. This research is a quasi experimental research with the population of students class X SMAN 01 Mukomuko The sample in this study is student class X 3 and class X 1 as a class experiment and X 2 as a class control. This study was conducted in April-May 2015. Data was collected using a mathematical creative thinking ability test. Data were analyzed using statistical tests Anova test of the lanes and the Advanced Test (BNT). Based on calculations obtained Anava no difference mathematically creative thinking abilities of students in class experimen I, experiment II, and class control. Based on the test of Least Significant Difference (LSD) showed that three treatments give different results. Based average value the final test learning  and conventional learning in develop student to think creatively mathematical good to teacher or a student. Keywords : Creative Thinking Mathematically, Inquiry

Abstract

AbstrakTujuan penelitian ini adalah mengetahui perbedaan kemampuan penalaran matematis siswa antara model discovery learning dan jigsaw. Jenis penelitian adalah eksperimen semu. Tempat penelitian diaksanakan di SMP Negeri 18 Kota Bengkulu. Populasi pada penelitian seluruh siswa kelas VII. Sampel penelitian dipilih secara acak sederhana yaitu kelas VII.1 sebagai kelas eksperimen 1, pembelajaran dengan menggunakan model discovery learning, kelas VII.5 sebagai kelas eksperimen 2, pembelajaran dengan menggunakan model kooperatif tipe jigsaw, dan kelas VII.3 sebagai kelas kontrol, pembelajaran dengan menggunakan model pembelajaran konvensional. Hasil penelitian ini menunjukan bahwa kelas eksperimen 1 memperoleh nilai rata-rata tes akhir (post-test) kemampuan penalaran matematis siswa yaitu 12,13, nilai rata-rata eksperimen 2 yaitu 11,45, dan nilai rata-rata kelas kontrol yaitu 9,26. Berdasarkan hasil analisis uji anava satu jalur, dengan signifikan 0,05 diperoleh 𝐹ℎ𝑖𝑡𝑢𝑛𝑔 = > 𝐹𝑡𝑎𝑏𝑒𝑙 = 0,34, maka H0 ditolak. Artinya ada perbedaan signifikan rata-rata kemampuan penalaran matematis siswa pada kelas eksperimen 1, kelas eksperimen 2, dan kelas kontrol. Berdasarkan uji beda nyata (BNT) menunjukan bahwa pembelajaran yang memberikan hasil penalaran matematis yang berbeda adalah model pembelajaran discovery learning dengan konvensional, dan model kooperatif tipe jigsaw dengan konvensional. Sedangkan pembelajaran dengan model discovery learning dan model kooperatif tipe jigsaw tidak memberikan hasil kemampuan penalaran matematis siswa yang berbeda. Model discovery learning dan model kooperatif tipe jigsaw memberikan hasil lebih baik bila dibandingkan dengan model konvensional.Kata kunci: kemampuan penalaran matematis, model discovery learning, model Jigsaw AbstractThe purpose of this study was to determine students' mathematical reasoning abilities with discovery learning models and jigsaw type cooperative learning models. This type of research is quasi-experimental research. The population in this study were all students of class VII SMP Negeri 18 Bengkulu City in the   academic year 2019/2020. The sample of this study was selected by simple random sampling, namely class VII.1 as experimental class 1 using the discovery learning models, class VII.5 as experimental class 2 using the jigsaw type cooperative learning models, and class VII.3 as control class using conventional learning models. Data were collected by means of tests of students' mathematical reasoning abilities. Based on the results of the one-way ANOVA test, there are significant differences in students' mathematical reasoning abilities in the experimental class 1, experiment class 2 and the control class. The results          of the real difference test (BNT) show that learning that gives different results is the discovery learning models with conventional learning models, and the jigsaw type cooperative learning model with conventional learning models. Meanwhile, learning with discovery learning models and jigsaw type cooperative learning models does not give different results for students' mathematical reasoning abilities. Discovery learning models and jigsaw type cooperative learning models give better results when compared to conventional learning.Keywords: mathematical   reasoning   ability,   discovery   learning   model,   Jigsaw   model

Abstract

Penelitian ini bertujuan menghasilkan Lembar Kerja Siswa (LKS) yang valid dan praktis untuk pembelajaran Contextual Teaching and Learning pada materi kubus dan balok; dan untuk untuk mengetahui efek potensialnya pada kemampuan pemecahan masalah matematis siswa. Penelitian ini adalah penelitian pengembangan dengan model four-D, yaitu Define (pendefinisian), Design (perancangan), Develop (pengembangan), dan Desseminate (penyebaran). Penelitian ini dilaksanakan pada semester genap tahun ajaran 2021/2022. Proses validasi dilakukan oleh 3 orang validator. Hasil telaah validator digunakan untuk merevisi Lembar Kerja Siswa. Analisis data validasi secara kualitatif dan kuantitatif menunjukkan Lembar Kerja Siswa yang dikembangkan valid. Selanjutnya Lembar Kerja Siswa disebarkan terbatas kapada 15 orang siswa SMP untuk diuji tingkat kepraktisannya. Data kepraktisan dikumpulkan dengan angket respon siswa. Diperoleh skor rata-rata kepraktisan sebesar 3,91 yang termasuk kategori praktis. Efek potensial LKS terhadap kemampuan pemecahan masalah matematis siswa telah terlihat dari hasil kerja siswa dalam LKS. Kata Kunci: Lembar Kerja Siswa, contextual teaching and learning, kubus dan balok, kemampuan pemecahan masalah matematis
