The purpose of this study was to improve students' critical thinking skills by using Scaffolding based Treffinger. The use of scaffolding by teachers has many forms, which can be in the form of questions, media or text-based. This article is a review of several studies / research (meta-analysis) on the use of scaffolding in learning. Scaffolding is given in full and continuously. After students get a sufficient and correct understanding, the scaffolding will be reduced and even completely eliminated. Treffinger's learning model is a learning model that trains students to find ideas in solving problems. Critical thinking is a characteristic of higher order thinking skills that are very important to be developed in school. Critical thinking skills can be trained and developed through learning that encourages students to explore, investigate, find and solve problems through learning activities in small groups. The fact is that students still have difficulty thinking critically. One way to overcome student difficulties in critical thinking is to use Scaffolding based Treffinger.

AbstrakTujuan dilakukan penelitian ini adalah mendeskripsikan kondisi kemampuan berpikir kreatif siswa jika ditinjau berdasarkan tingkat resiliensi yang dimiliki oleh siswa. Penelitian ini didasari oleh adanya dampak perubahan pola belajar siswa karena pandemi covid-19. Kemapuan memberikan ide yang tidak umum dan hanya digunakan oleh beberapa orang tertentu untuk menyelesaikan masalah matematika disebut dengan kemampuan berpikir kreatif. Terdapat empat indikator siswa dikatakan kreatif diantaranya adalah kelancaran, keluwesan, orisinalitas, dan kemampuan memerinci. Resiliensi matematis siswa adalah kegigihan siswa dalam menghadapi permasalahan dalam pembelajaran matemtika. Metode yang digunakan adalah metode kualitatif dengan tujuan untuk mendapatkan gambaran secara menyeluruh terkait kemampuan berpikir kreatif tingkat resiliensi siswa secara lebih mendalam. 30 siswa kelas VII A SMP Negeri 1 Batu Ketulis, Lampung Barat Tahun Pelajaran 2020/2021 merupakan sampel yang diambil kemudian direduksi menjadi 6 siswa dengan menggunakan teknik pengambilan sampel didasarkan oleh pertimbagan tertentu. Data dikumpulkan dengan memberikan kuisioner, soal materi bangun datar, dan wawancara. Instrumen yang digunakan berupa angket kemampuan resiliensi matematis siswa, tes uraian pada materi segi empat (bangun datar), dan pedoman wawancara. Kesimpulan yang diperoleh adalah indikator kelancaran dan keterincian sering muncul pada siswa dengan tingkat resiliensi tinggi, indikator kelancaran muncul pada siswa yang memiliki resiliensi sedang sedang, dan siswa dengan tingkat resiliensi rendah belum mampu memunculkan satupun indikator berpikir kreatif. Kata kunci: Berpikir Kreatif; Resiliensi Matematis Abstract The purpose of this research is to describe condition of students' creative thinking skills when viewed based on the level of resilience possessed by students. This research is based on the impact of changes in student learning patterns due to the COVID-19 pandemic. The ability to provide ideas that are not common and only used by certain people to solve mathematical problems is called the ability to think creatively. There are four indicators that students are said to be creative including fluency, flexibility, originality, and elaboration. Students' mathematical resilience is the persistence of students in dealing with problems in learning mathematics. The method used is a qualitative method with the aim of getting a comprehensive picture of students' creative thinking skills at the level of resilience in more depth. 30 students of class VII A Junior High School 1 Batu Ketulis, West Lampung in the 2020/2021 academic year are samples taken and then reduced to 6 students with using a sampling technique based on certain considerations. Data was collected by giving questionnaires, questions about data building materials, and interviews. The instrument used was a questionnaire on students' mathematical resilience abilities, a description of the rectangular material description (data structure), and interview guidelines. The conclusion obtained is that indicators of medium and detail often appear in students with high levels of resilience, indicators appear in students who have resilience, and students with low levels of resilience have not been able to bring up indicators of creative thinking.Keywords: Creatif Thinking; Mathematical Resilience

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 student's mathematical representation Keywords: Problem Based Learning, Critical thinking, Mathematical Representation

Publisher : Program Studi Pendidikan Matematika Program Pascasarjan Universitas Negeri Yogyakarta

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.
