Abstract

Materi matematika dalam pembelajaran paling sering bersumber dari buku paket, namun jumlah yang tersedia di sekolah terbatas dan guru tidak mengoptimalkan keberadaan teknologi untuk memberikan materi yang efektif dan menarik. Akibatnya, peserta didik tidak menyelesaikan latihan sesuai prosedur matematika dan mereka pesimis. Tujuan penelitian secara umum adalah menghasilkan Lembar Kerja Peserta Didik (LKPD) berbasis pendekatan berpikir metaforis untuk kelancaran prosedural mereka pada ciri-ciri yang valid. Penelitian ini menggunakan penelitian dan pengembangan dengan model tahapan ADDIE. Pesertanya adalah peserta didik kelas 9 di Sekolah Menengah Pertama. Pengumpulan data dilakukan dengan teknik observasi, angket, dan wawancara. Hasil penelitian menunjukkan bahwa karakteristik LKPD yang dikembangkan sudah valid. Hasil uji validitas LKPD diperoleh sebesar 90% dan hasil uji coba peserta didik sebesar 93%. Implikasi dari LKPD ini adalah membantu peserta didik untuk belajar mandiri, dan LKPD ini membantu peserta didik memecahkan masalah matematika sesuai dengan prosedural, dibantu dengan langkah-langkah pendekatan berpikir metaforis, kegiatan belajar mengajar lebih efektif. Kata kunci: Kelancaran prosedural, Pendekatan metaphorical thinking, Pengembangan lembar kerja. / The mathematics materials in learning mostly used package books, but the provided resources in the school were limited and teachers did not optimize the existing technology to provide effective and interesting materials. As a consequence, students did not complete the exercise according to mathematical procedures and they were pessimistic. The general research purpose was to produce a metaphorical thinking approach-based worksheet for students' procedural fluency on valid characteristics. This study used research and development by the ADDIE stage model. The participant was 9th-grade students in junior high school. Data collection were observation, questionnaires, and interview techniques. The results showed that the characteristics of the developed worksheet have been valid. The results of the worksheet validity test were obtained by 90% and the results of the trial of students were 93%. The implications of this worksheet are helpful for students to independent learning, and this worksheet helps students solve mathematical problems in accordance with procedural, assisted by steps of the metaphorical thinking approach, teaching and learning activities are more effective. Keywords: Metaphorical thinking approach, Procedural fluency, Worksheet development.
