Eksplorasi Penalaran Logis Calon Guru Matematika Melalui Pengintegrasian Pendekatan STEM dalam Menyelesaikan Soal

AbstrakRendahnya kemampuan penalaran menjadi penyebab rendahnya prestasi matematika. Diperlukan solusi, diantaranya STEM. Penelitian ini bertujuan mengeksplorasi penalaran logis calon guru matematika melalui pengintegrasian pendekatan STEM dalam menyelesaikan soal matematika. Jenis penelitian yaitu kualitatif dengan pendekatan deskriptif. Subjek penelitian adalah seorang mahasiswa calon guru matematika yang dipilih secara purposive sampling. Instrumen penelitian meliputi utama dan pendukung yaitu TPL dan pedoman wawancara. Teknik analisis data meliputi reduksi data, penyajian data, interpretasi data, dan penarikan simpulan. Hasil penelitian menunjukkan subjek melakukan eksplorasi software Geogebra untuk mengidentifikasi informasi yang diperlukan sesuai pengetahuan yang dimiliki. Subjek juga melakukan beberapa teknik mengoperasikan aplikasi Geogebra, seperti dilatasi dan refleksi. Selanjutnya subjek menekankan beberapa titik-titik koordinat selama membuat grafik fungsi yang ditunjukkan software Geogebra untuk membuktikan jawabannya melalui subtistusi setiap titik-titiknya. Subjek meyakini kebenaran hasil yang ditunjukkan pada Geogebra. Pengintegrasian teknologi dalam setiap matakuliah diperlukan agar mahasiswa dapat mengembangkan penalaran logis dalam menyelesaikan masalah matematika. Logical Reasoning Exploration for Mathematics’ Candidate Teacher through Integration of STEM Approach in Solving Problem AbstractThe low reasoning ability is the reason for low mathematical achievement. A solution is needed, including STEM. This research has aimed to explore the logical reasoning of mathematics teacher candidate through integrating the STEM approach in solving a math problem in a task. This research uses descriptive qualitative. The subject of this research is the students of the mathematics education program of STKIP PGRI Jombang. These research instruments involve main and supportive that consist of TPL and interview. In analyzing data, it consists of reduction data, presentation data, interpretation data, and conclusion. The result of this research shows that the subject does exploration through "Geogebra" to identify the information which is appropriate with its knowledge. The subject also does several techniques in operating "Geogebra", such as; dilated and reflection. Moreover, the subject emphasizes several coordinate points while making a graphic of function which is shown in "Geogebra", because it is suitable for things that have already done in a worksheet. Integrating technology in each course is needed so that students can develop logical reasoning in solving mathematical problems.
