Abstract
This research is motivated by the low mathematical problem solving ability of students, where most people blame the learning model while there are many factors that influence this, one of which is students' self-confidence. This study aims to determine the differences in students' mathematical communication skills in terms of self-confidence. This type of research is an expost facto study and was conducted at MTs Negeri 2 Kolaka using a sample of 48 students. From the results of the analysis carried out, the average problem-solving ability of students is 50.94 which if converted in table 2 then the value is in the less category. Furthermore, from the inferential analysis obtained > so that it can be concluded that there are significant differences in mathematical problem solving abilities between students with very high, high, medium and low Self Confidence. From the results of further analysis, it was concluded that students with very high self-confidence would have better problem-solving abilities than other students
Highlights
This result means that students with Self Confidence will have different problem solving abilities
From the results of further analysis, it was concluded that students with very high self-confidence had better problem-solving abilities than other students
Untuk peneliti selanjutnya diharapkan didalam penelitiannya selain meningkatkan kemampuan pemecahan masalah matematis juga dapat meningkatkan self-confidence ata kepercayaan diri siswa
Summary
Received 04 November 2021; Received in revised form 16 November 2021; Accepted 23 December 2021. Penelitian ini dilatarbelakangi pada rendahnya kemampuan pemecahan masalah matematis siswa, dimana kebanyakan orang menyalahkan model pembelajarannya sedangkan terdapat banyak faktor yang mempengaruhi hal tersebut, salah satunya adalah self confidence (kepercayaan diri) siswa. Penelitian ini bertujuan untuk mengetahui perbedaan kemampuan pemecahan masalah matematis siswa ditinjau dari self confidence. Dari hasil analisis yang dilakukan diperoleh rata-rata kemampuan pemecahan masalah siswa adalah 50,94 yang mana jika dikonversi maka nilai tersebut berada pada kategori kurang. Tabel sehingga dapat disimpulkan terdapat perbedaan yang signifikan kemampuan pemecahah masalah matematis antara siswa dengan Self Confidence sangat tinggi, tinggi, sedang dan rendah. Hasil ini berarti siswa dengan Self Confidence akan memiliki kemampuan pemecahan masalah yang berbeda pula. Selanjtnya dari hasil analisis lanjut diperoleh kesimpulan bahwa siswa dengan self confidence sangat tinggi memiliki kemampuan pemecahan masalah yang lebih baik dibandingkan dengan siswa lainnya.
