Pengembangan Perangkat Pembelajaran Matematika Berbasis Konstruktivisme Untuk Melatih Kemampuanberpikir Kritis Siswa Sma Kelas X

Abstract

Teaching learning process in math hasn't been requiring student to construct their knowledge and to exercise their critical thinking. So need to develop constructivism instruction materials for exercise student's ability in critical thinking. This research aim to: (1) Produce the valid and practice constructivism instruction materials to exercise student's ability in critical learning, (2) Know effectiveness it to exercise student's ability in critical learning. Instruction materials were developed in this research are plan learning, student worksheet and test of student's ability in critical thinking. Development research methods are used by this research. The methods consist of analysis, design, evaluation and revision. Collecting data use Observation and test. Observation is used to know the student's activity in teaching learning process and to know the teacher's ability in learning constructivism approach management. Test is used to know the result of student's ability in critical thinking after teaching learning process. Subjects in this research are students from the first semester in class X.7 at SMA Negeri 10, Palembang . The total subjects are 40 students. The conclusions are: 1. Instruction materials process development is for quadrate equivalence only that begins from analysis design, and than evaluation until revision. 2. Instruction materials prototype is develope, fulfill in valid and practice criteria also have effect potential. 3. Some aspects of student's activity in learning process do not effective; because restructure (57.92 %) and review (55.00 %) just in enough category. The result learning test to evaluate student's ability in critical thinking is 24.38. It means the student's ability in critical thinking is good category. The final conclusion is constructivism instruction materials can practice to exercise student's ability in critical thinking for math learning.

Pengembangan Perangkat Pembelajaran Untuk Meningkatan Kemampuan Berpikir Kreatif

“…Menteri (Ariyanto, 2011;Astuti, 2009;Tati, Zulkardi, & Hartono, 2009). Perangkat pembelajaran adalah sekumpulan sumber belajar yang digunakan pendidik dan peserta didik dalam kegiatan pembelajaran (Ariyanto, 2011 (Rusiyanti, 2011;Syahbana, 2012). Tidak hanya itu, metakognisi juga dapat ditingkatkan dengan mengembangkan bahan ajar berbasis masalah kontekstual (Amir & Wardana, 2018).…”

Implementasi Model Pembelajaran Kooperatif Tipe Jigsaw dengan Menggunakan Pendekatan Active Learning pada Materi Bangun Datar

“…Besarnya peranan tersebut, menjadikan matematika sebagai mata pelajaran wajib di sekolah, dan perlunya penguasaan konsep yang kuat sejak dini, serta dapat menumbuhkan kemampuan siswa dalam berpikir logis, analitis, sistematis, kritis, kreatif dan bekerja sama secara efektif (Hardini, 2012) dengan tujuan agar siswa dapat memiliki kemampuan memperoleh, mengelola, memanfaatkan informasi dan kompetitif (Rusiyanti, 2011). Namun, sebagian besar siswa masih saja menganggap matematika sebagai mata pelajaran yang tidak menyenangkan, serta materinya yang terkesan sulit dan abstrak untuk dipahami (Yanto, 2018).…”

Development of Problem-Oriented Mathematics Learning Videos on Scale Material for the Fifth-Grade Elementary School Students

“…Mathematics is used as the basis for mastery of science and technology [6]. In line with that, mathematics as an abstract symbolic system requires reasoning and critical thinking in imagining mathematical theories and concepts through the power of imagination which will have an impact on their understanding of mathematical material [7].…”
