Abstract

Tujuan utama penelitian ini adalah untuk memperoleh gambaran mengenai peningkatan kemampuan berpikir kreatif siswa yang pembelajarannya dengan pembelajaran berbasis masalah open-ended (PBMO) bila dibandingkan dengan pembelajaran konvensional. Disain penelitian ini adalah disain eksperimen yang dinamakan delayed counter balanced design. Dalam penelitian ini, kelompok eksperimen memperoleh PBMO dan kelompok kontrol memperoleh pembelajaran konvensional. Untuk mendapatkan data hasil penelitian digunakan instrumen berupa tes kemampuan berpikir kreatif. Populasi penelitian adalah siswa SMP Negeri Kota Bandar Lampung dengan subjek sampel adalah siswa kelas VIII sebanyak dua kelas dari masing-masing sekolah peringkat tinggi (SMPN 4) dan sekolah peringkat sedang (SMPN 12) yang dipilih dengan teknik purposive sampling. Berdasarkan analisis data yang dilakukan diperoleh kesimpulam bahwa terdapat perbedaan rata-rata peningkatan kemampuan berpikir kreatif antara siswa yang mengikuti pembelajaran pada kedua kelompok sampel.   Kata Kunci : PBM berbasis Open-ended, Kemampuan Berpikir Kreatif Matematis

Abstract

Matematika merupakan salah satu mata pelajaran yang memegang peranan penting dalam pendidikan. Matematika dapat mengembangkan pemikiran kritis, kreatif, sistematis, dan logis, matematika juga telah memberikan kontribusi dalam kehidupan sehari-hari mulai dari hal yang sederhana seperti perhitungan dasar sampai hal yang kompleks dan abstrak. Beberapa fokus dalam pengembangan pembelajaran matematika yaitu kemampuan berpikir kreatif matematis siswa. Kemampuan berpikir kreatif diperlukan siswa agar dapat mengungkapkan banyak ide-ide dalam penyelesaian masalah. Salah satu pembelajaran matematika yang berorientasi pada kemampuan berpikir kreatif adalah dengan pembelajaran guided discovery. Pembelajaran guided discovery merupakan salah satu strategi untuk membantu kesulitan siswa dalam belajar matematika. Belajar dengan penemuan adalah didalam proses belajar seorang siswa dihadapkan dengan suatu masalah sehingga siswa dapat mencari jalan pemecahan sendiri dengan bimbingan guru. Dalam kegiatan pembelajaran siswa disarakan untuk menemukan sesuatu, merumuskan suatu hipotesa, atau menarik suatu kesimpulan sendiri. Dalam guided discovery, menempatkan guru sebagai fasilitator, guru membimbing siswa dimana guru diperlukan. Tujuan dari kajian ini adalah untuk mengetahui bagaimana guided discovery diaplikasikan dalam pembelajaran matematika, untuk mengetahui kemampuan berpikir kreatif siswa. Hasil kajian menunjukkan pembelajaran guided discovery dapat merangsang berpikir kreatif siswa dan membantu siswa dalam menemukan pengetahuan atau konsep yang baru.

Abstract

Matematika merupakan salah satu mata pelajaran yang penting untuk dipelajari karena keberadaannya dapat membantu manusia untuk memecahkan berbagai masalah dalam kehidupan sehari-hari. Salah satu peran dan tugas pendidik  dalam rangka memaksimalkan kesempatan belajar siswa adalah agar siswa memiliki kemampuan pemecahan masalah matematis. Hal tersebut dilakukan agar siswa bisa menyelesaikan permasalahan didalam kehidupannya. Untuk itu, pendidik dalam prosesnya perlu mempertimbangkan model pembelajaran yang dapat mendorong siswa untuk mencapai kemampuan tersebut, yaitu model pembelajaran Creative Problem Solving  (CPS). Model pembelajaran Creative Problem Solving (CPS) adalah suatu model pembelajaran yang memusatkan pada pengajaran dan keterampilan pemecahan masalah, yang diikuti dengan penguatan kreatifitas. Noller (Isaksen, Dorval, & Treffinger, 2011: 26) mengemukakan bahwa “Creative Problem Solving or CPS is a process, a method, a system for approaching a problem in a imaginatif way resulting in effective action”. Hal ini berarti bahwa CPS adalah sebuah proses, sebuah metode, sebuah sistem pendekatan masalah dengan cara yang imajinatif untuk menghasilkan solusi melalui tindakan yang efektif. Untuk lebih lanjut, artikel ini akan mengkaji apa itu Creative Problem Solving  (CPS) dan hubungannya dengan kemampuan pemecahan masalah matematis dalam pembelajaran matematika.

Abstract

This study aims to determine the effectiveness of problem-based learning model in terms of the ability to think critically and mathematical representation of grade VIII students at a State Junior High School in Bandarlampung City. The population in this study are all students of class VIII distributed in eleven classes. The samples of this study are the students of two classes VIII whose class is selected by purposive random sampling technique. The research design is Pre-test Post-test Control Group Design. Mann-Whitney U non parametric test results on critical thinking and mathematical representation, indicating that H0 is rejected, thus drawn the conclusion that mathematical critical thinking and mathematical representation of students who follow PBL is higher than mathematical critical thinking and mathematical representation of students following learning conventional. The proportion test shows that the percentage of students who have critical thinking skills and mathematical representations are categorized well in the class using the PBL more than 60% of the number of students. The result of the research shows that learning with effective PBL model is viewed from critical thinking ability and students mathematical representation Keywords:  Problem Based Learning, Critical thinking, Mathematical Representation

Abstract

This research development aimed to develop of worksheet based on guided discovery for increasing mathematical creative thinking and student’s self-efficacy. Development stage in this study is a preliminary study, planning, development of worksheet, worksheet validation, and field testing. The subject of this research is the students of class 10A3 and 10A5 MAN 1 Central Lampung in the Academic of 2017/2018. The data of this research were obtained by observation, interview, mathematicalcreative thinking ability test and self-efficacy scale. The result of the validity by subject matter expert and media expert showed that the worksheet is considered excellent. The Initial field testing results indicate that worksheet is included in either category. The field testing results showed that (1) the student’s mathematical creative thinking aspect was effective because seen from the N-Gain of 0,54 which included in the category of moderate improvement and (2) the student’s self-efficacy was effective because seen from the N-Gain of 0,36 which included in the category of moderate improvement. It can be concluded that worksheet based on guided discovery effective way to improve the mathematical creative thinking ability and student’s self-efficacy.

Abstract

This current study aimed to determine the effectiveness of the guided discovery model in increasing students' critical thinking skills and critical thinking dispositions. Each experiment and control group consisted of 34 students of grade X of one high school class in Bandar Lampung city. The data were obtained through mathematical critical thinking skills test and critical thinking dispositions scale. The data were analyzed qualitatively and quantitatively to obtain a comprehensive description of the impact of learning on the increase in both skills. The results showed that the increase of students’ critical thinking skills and critical thinking dispositions after learning was in the effective category. Other finding showed that the use of a contextual problem in the beginning of learning could trigger students to activate their prior knowledge. In this way, students used some strategies and made an appropriate conclusion confidently. This study suggested that the guided discovery model can be an alternative to improve students' critical thinking skills and critical thinking dispositions.
