Abstract

Kemampuan pemecahan masalah matematis sangat penting dimiliki oleh siswa dalam belajar matematika, namun pada kenyataannya kemampuan pemecahan masalah matematis siswa rendah serta kurang percaya diri dalam menyelesaikan masalah. Hal ini terbukti dari jawaban yang ditulis oleh siswa dengan tidak memahami masalah yang ditanyakan dan tidak nampak perencanaan dalam menyelesaikan masalah serta tidak mengevaluasi kembali dari kebenaran jawaban yang diberikan. Oleh karena itu penting menerapkan model berpikir induktif.Tujuan penelitian ini adalah menganalisis berapa besar model berpikir induktif mempengaruhi kemampuan pemecahan masalah matematis siswa jika ditinjau dari kepercayaan diri siswa. Berpikir induktif meliputi mengumpulkan data, mengola dan menguji kebenaran data, tahap pembentukan kognitif mengingat dan memahami, menganalisis, tahap aplikasi prinsif memuat proses kognitif memahami dan mengevaluasi, menggunakan proses kognitif yang lebih tinggi dalam rangka mencapai proses kognitif dibawahnya. Siswa yang memiliki kepercayaan diri tinggi lebih baik berpikir induktifnya dalam memecahkan masalah matematis, sementara siswa yang memiliki kepercayaan diri rendah cendrung kurang. Metode penelitian ini adalah metode kuantitatif. Populasi Penelitian adalah SMP Negeri yang ada di Kecamatan Percut Sei Tuan, Sampel yang digunakan adalah SMP Negeri empat Percut Sei Tuan. Temuan yang diperoleh model berpikir induktif berpengaruh signifikan terhadap kemampuan pemecahan masalah matematiis siswa dan siswa yang pada dasar memiliki kepercayaan diri tinggi lebih mendukung kemampuan pemecahan masalah matematisnya.

Abstract

Understanding the concepts and solving problems in the integral calculus course is the problem most often faced by students during the learning process. Therefore, an analysis must be made of the types of learning difficulties faced by students in integral calculus courses, especially indeterminate integrals. The purpose of this research is to identify what problems students face when solving indeterminate integral problems in integral calculus courses. The results are expected to provide an overview of the types of learning challenges faced by students while studying. The type of research used iscase study research with a qualitative approach. The research subjects were 20 students from the second semester of unit 1 of IAIN Lhokseumawe's Tadris Mathematics study programme. The results showed that there were three learning difficulties faced by students, namely Type I (Rigour), Type II (Concept Understanding) and Type III (Calculation Process).

Abstract

This research is crucial since students struggle with math. They want to "Analysis of Problem Solving Ability and Independent Learning Based on IT-Assisted PBL at Nurul Azizi Integrated Islamic Middle School" . This study is quantitative quasi-experimental. Fix IT issues Scholars value research and freedom. We tested eighth-graders at Nurul Azizi Integrated Islamic Middle School. Random VIII A and B have 30 students. Control and experimental groups are examined. VIIIB/VIIIA comparison. The control group employed conventional methods, while the experimental group used IT-based problem-based learning. Statistics-based research. A statistical analysis. Sample statistics predict a larger population. Parametric statistics estimates population parameters from distribution assumptions. Test a theory before experimenting. 1) Averages define typical. 2) Consistency unites. Three testable hypotheses tell or foretell. Discuss study results: Math issue-based instruction assists SMP IT Nurul 'Azizi pupils. This was expected as the experimental group scored 82.27 and the control 70. SMP IT Nurul 'Azizi's problem-based learning increases student autonomy more than conventional techniques with a 5% significance threshold (5.793>2.002) and a 2-way significant value (t-tailed) of 0.000. Compared to 74, the experimental group scored 85.83. SMP IT Nurul 'Azizi students' arithmetic problem-solving skills are linked to learning, with a 5% significant level (6.55>2.002) and 2-way t-tailed value of This study uses a two-way ANOVA with α = 0.05. At SMP IT Nurul 'Azizi, pupils' arithmetic competency was influenced by their learning model and baseline ability (p-value 0.05). This study uses a two-way ANOVA with α = 0.05. The significance threshold is 0.036, below 0.05.
