Model Pembelajaran Osborn Untuk Meningkatkan Kemampuan Pemecahan Masalah Matematis Siswa

Abstract

The purpose of this research is to find out the increase of student’s mathematical problem solving competence through the implementation of Osborn Learning Model, as well as compare it with the student who earned conventional learning. In addition, the purpose of this research is to find out the increase of mathematical problem solving competence on a group of student with high, middle, and low capability. The next purpose is to find out the attitude of the students against the osborn learning model. Methods used in this research is quasi Experimenter Method with pretest and post-test Marginalized Control Design. Population on this research are all of students of VIII grades in SMPN 1
 Bandung. Samples on this research are two classes of VIII grades, one class as
 Experimental Class and the other one as control class. Research data obtained
 through the test of student’s mathematical problem solving competence, questionnaire, and observation sheets. The result of this
 research shows that the increasing of student’s mathematical problem solving
 competence with Osborn Learning Model better than the increasing of student’s mathematical problem solving competence
 with conventional learning. There are differences in the increasing competence on
 the groups of high capability, middle capability and low capability in osborn class and conventional class. In general, the
 students give a positive attitude against
 Osborn Learning Model.

Implementasi Analytic Hierachy Process (AHP) Dalam Sistem Pengambilan Keputusan Pemilihan Metode Pembelajaran Riset Operasi

“…Pemilihan ketiga metode pembelajaran berdasarkan penelitian yang telah dilakukan Elita dkk yang memberikan hasil bahwa model pembelajaran Problem Based Learning memberikan pengaruh terhadap kemampuan pemecahan masalah matematis peserta didik [19]. Azzahro juga menunjukkan hasil dalam penelitiannya bahwa Problem Based Learning, Drill dan Latihan dapat diterapkan pengajar dalam pembelajaran matematika untuk meningkatan kemampuan pemecahan masalah [20]. Selanjutya, Pratiwi menunjukkan dalam hasil penelitiannya bahwa pembelajaran matematika dengan menerapkan model Blended Learning bersifat praktis dan mudah untuk diterapkan [21].…”

Efektivitas Pendekatan Realistic Mathematics Education (Rme) Berbantuan Aplikasi Edmodo Terhadap Kemampuan Pemecahan Masalah Matematis Siswa

“…Dalam kenyataannya, kemampuan pemecahan masalah siswa pada saat ini masih rendah (Aceh & Sapnaranda 2016, Nurafifah et al 2016. Menurut lembaga survey TIMSS (2015), Indonesia berada di peringkat 44 dari 49 negara dengan rata-rata skor 397 di bawah rata-rata skor internasional yakni 500 (Syamsul Hadi dan Novaliyosi 2019).…”

Improving Students' Mathematical Problem Solving Ability in Trigonometry Material Using the Flipped Classroom Model

“…If it is based on the causal factors found, a learning process is needed that can encourage students to be actively involved in the process of solving mathematical problems. Nurafifah, Nurlaelah, and Usdiyana (2016), argue that if teachers are willing to utilize certain appropriate learning models it will have a positive influence on students' mastery of mathematical problem solving. A similar opinion also states that the use of models that are appropriate to the learning objectives to be achieved will have a positive impact on student learning outcomes (Alifah, 2019;Fahrurrozi, Mohzana, & Murcahyanto, 2021;Khoerunnisa & Aqwal, 2020;Warsita, 2018).…”
