Pembelajaran dengan Visual Scaffolding untuk Mengembangkan Kemampuan Siswa dalam Menyelesaikan Masalah Terbuka pada Materi Fungsi Kuadrat.
Abstract
Penelitian ini bertujuan untuk merancang suatu lintasan pembelajaran dengan visual scaffolding pada materi fungsi kuadrat. Peneliti menitikberatkan pada kemampuan siswa menyelesaikan masalah terbuka. Pembelajaran ini disertai dengan penggunaan media pembelajaran geogebra untuk membantu siswa mengeksplorasi konsep fungsi kuadrat. Penelitian ini menggunakan design research dengan tiga tahapan yang meliputi penelitian awal, implementasi dan analisis retrospektif. Data terkait dengan aktivitas dan strategi yang digunakan siswa dalam menyelesaikan masalah yang diberikan selama pembelajaran berlangsung dikumpulkan melalui jawaban tertulis siswa di LKS, hasil post test, wawancara dan observasi yang kemudian dianalisis secara deskriptif. Rumusan akhir lintasan pembelajaran dari penelitian desain ini memiliki tahapan sebagai berikut : (1) mengeksplorasi karakteristik grafik fungsi kuadrat dengan memanipulasi media visual, (2) mengeksplorasi titik potong grafik fungsi kuadrat dengan memanipulasi media visual, (3) mengeksplorasi titik puncak grafik fungsi kuadrat dengan memanipulasi media visual, (4) menemukan kemungkinan jawaban permasalahan open ended dengan memanipulasi media visual. Dari temuan yang diperoleh, dapat disimpulkan pembelajaran dengan menggunakan visual scaffolding dapat membantu siswa mengembangkan kemampuan menyelesaikan permasalahan open ended.

This research aims at designing a learning trajectory with visual scaffolding on quadratic functions. The study emphasized the student’s ability on solving open-ended problems. This learning is supported by the use of instructional media GeoGebra to help students to explore the concept of quadratic function. Design research was deliberately chosen as the method of this study, with the following three steps: preliminary research, teaching implementation and retrospective analysis. The data related to student’s activities and strategies that students used to solve the given problems during learning processes were collected using student’s written works on some worksheets, post tests, interviews and observations. Final learning trajectory of this research has four steps: (1) exploring characteristic of quadratic function graph by manipulating visual media, (2) exploring intersection point of quadratic function graph with x-axes by manipulating visual media, (3) exploring vertex point of quadratic function graph by manipulating visual media, (4) finding possible solutions in solving open ended problems by manipulating visual media. The results showed that visual scaffolding was able to develop the students’ ability on solving open ended problems on quadratic function materials.
