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.
Model pembelajaran yang akan disampaikan oleh guru mempengaruhi hasil belajar peserta didik. Dalam proses memperoleh hasil belajar yang baik diperlukan model pembelajaran yang tepat. Guru perlu memberikan kebebasan kepada peserta didik untuk berpikir secara bebas, kreatif dan belajar mandiri. Penelitian ini bertujuan untuk mengetahui ada atau tidaknya pengaruh terhadap hasil belajar matematika peserta didik kelas X SMK Negeri 3 Jombang sebelum dan sesudah diterapkan model pembelajaran problem posing tahun pelajaran 2019/2020 pada materi barisan dan deret aritmatika. Penelitian ini merupakan penelitian kuantitatif dengan menggunakan rancangan penelitian “One-Group Pretest-Posttest Design”. Populasi dalam penelitian ini adalah peserta didik kelas X SMK Negeri 3 Jombang dengan sampel penelitiannya yaitu kelas X TKJ 2 tahun pelajaran 2019/2020 semester genap yang berjumlah 30 peserta didik. Metode pengumpulan data yang digunakan dalam penelitian ini adalah metode tes. Instrumen yang digunakan adalah lembar tes hasil belajar matematika yang berbentuk uraian. Kesahihan instrumen penelitian ini diperoleh melalui uji validitas dan reliabilitas. Teknik analisis data dilakukan dengan uji normalitas dan uji hipotesis menggunakan program SPSS 20.0. Berdasarkan hasil penelitian yang sudah terkumpul dan sudah dianalisis, diperoleh nilai sig.(2-tailed) pada Paired Samples T Test sebesar 0,000 yang artinya nilai sig.(2-tailed) < α yaitu 0,000 < 0,05 maka H0 ditolak dan H1 diterima. sehingga dapat disimpulkan bahwa ada pengaruh terhadap hasil belajar matematika peserta didik kelas X SMK Negeri 3 Jombang sebelum dan sesudah diterapkan model pembelajaran problem posing tahun pelajaran 2019/2020 pada materi barisan dan deret aritmatika.Kata kunci: : Pengaruh, Problem Posing, Hasil Belajar
Spatial skills are defined as a person's ability to draw conclusions based on arguments from a situation regarding form, location, path, relationships between entities, and relationships between entities and terms of reference. Students of mathematics education STKIP PGRI Jombang are prospective teachers who are required to have skills in learning mathematics, one of which is spatial skills. Therefore, spatial skills must be possessed by students of mathematics education at STKIP PGRI Jombang because they are related to geometry material taught from primary to secondary education. The purpose of this study was to determine whether there is a relationship between cognitive style and spatial skills of mathematics education students at STKIP PGRI Jombang. This type of research is correlational quantitative research. The population of this research is the students of the 2021 class of mathematics education study program STKIP PGRI Jombang. as a sample are students of class A . There are two instruments, namely GEFT and TKSM. Based on calculations using Product Moment Correlation analysis with the help of the SPSS computer program, the significance value (0.00) (0.05). This shows the relationship between the two variables is significant. The Pearson Correlation score between cognitive style and spatial skills is 0.927. So this study shows that there is a relationship between cognitive style and spatial skills.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
