Abstract

Penelitian terdahulu secara konsisten menunjukkan adanya masalah fundamental dalam pembelajaran geometri di sekolah dasar, yang ditandai dengan rendahnya kemampuan geometri siswa dan miskonsepsi yang telah terjadi sejak kelas awal dan terbawa hingga jenjang SMP. Miskonsepsi yang terbentuk sulit diubah karena setiap individu membangun pengetahuan atas dasar pengalamannya sendiri. Intervensi dini di kelas I SD terbukti efektif mencegah miskonsepsi, namun penelitian tentang strategi guru di kelas I masih sangat terbatas. Penelitian ini bertujuan untuk mendeskripsikan strategi guru dalam mengembangkan kemampuan geometri di kelas I SDN Rawamangun 09 Jakarta, meliputi perencanaan, pelaksanaan, dan evaluasi pembelajaran. Penelitian ini menggunakan pendekatan kualitatif dengan jenis studi kasus. Subjek penelitian adalah guru kelas I di SDN Rawamangun 09 Jakarta. Teknik pengumpulan data dilakukan melalui observasi partisipatif, wawancara mendalam, dan dokumentasi. Analisis data menggunakan model Miles dan Huberman yang meliputi reduksi data, penyajian data, dan penarikan kesimpulan. Keabsahan data diperoleh melalui triangulasi sumber dan teknik. Penelitian ini memberikan kontribusi bagi pengembangan ilmu pendidikan, khususnya dalam kajian strategi pembelajaran geometri di kelas awal, serta menjadi acuan bagi guru dan peneliti selanjutnya dalam merancang pembelajaran geometri yang efektif untuk mencegah miskonsepsi sejak dini. Kata kunci: Strategi Guru, Kemampuan Geometri, Teori Van Hiele, Kelas I SD ***** Previous research consistently shows fundamental problems in geometry learning in elementary schools, characterized by low geometry ability and misconceptions that have occurred since early grades and persist through junior high school. Misconceptions are difficult to change because each individual builds knowledge based on their own experiences. Early intervention in grade I elementary school has been proven effective in preventing misconceptions, yet research on teacher strategies at this early grade remains very limited. This study aims to describe teacher strategies in developing geometry ability in grade I of SDN Rawamangun 09 Jakarta, covering learning planning, implementation, and evaluation. This research uses a qualitative approach with a case study design. The research subject is the grade I teacher at SDN Rawamangun 09 Jakarta. Data collection techniques include participatory observation, in-depth interviews, and documentation. Data analysis uses the Miles and Huberman model, which includes data reduction, data presentation, and conclusion drawing. Data validity is obtained through source and technique triangulation. This research contributes to the development of educational science, particularly in the study of geometry learning strategies in early grades, and serves as a reference for teachers and future researchers in designing effective geometry learning to prevent misconceptions from an early stage. Keywords: Teacher Strategies, Geometry Ability, Van Hiele Theory, Grade I Elementary School
