Abstrak. Penelitian ini merupakan penelitian tindakan kelas yang bertujuan untuk meningkatkan kemampuan pemecahan masalah dan kemandirian belajar mahasiswa melalui pembelajaran berbasis masalah. Subjek penelitian adalah mahasiswa program studi pendidikan matematika yang mengambil mata kuliah Aplikasi Komputer. Penelitian dilaksanakan dalam 3 siklus, dimana setiap siklus terdiri atas 2 pertemuan. Data diperoleh melalui tes kemampuan pemecahan masalah dan angket kemandirian belajar. Hasil tes pemecahan masalah dari siklus I sampai dengan siklus III selalu mengalami peningkatan. Rata-rata tes pemecahan masalah pada siklus I sebesar 71,58; pada siklus II sebesar 76,67; dan pada siklus III sebesar 81,88. Data kemandirian belajar yang diambil menggunakan angket menunjukkan terjadi peningkatan dari siklus I ke siklus berikutnya. Pada siklus I, rata-rata kemandirian belajar sebesar 60,53; pada siklus II sebesar 65,29; dan pada siklus III sebesar 68,12. Berdasarkan hasil tersebut dapat dikatakan bahwa penerapan pembelajaran berbasis masalah dapat meningkatkan kemampuan pemecahan masalah dan kemandirian belajar mahasiswa yang mengikuti mata kuliah aplikasi komputer.Abstract. This research was action research which aimed to improve the problem solving skills and the self-directed learning using problem based learning. The subject of the research was the student at the programme of study in mathematics education who took Computer Application courses. This research was held in three cycles in with two meetings at each cycle. The data were taken through problem solving skills test and self-directed learning questionnaire. The problem solving test result from the first to the third cycle shown an increase. The average first cycle was 71,58, the second cycle was 76,67, and the third cycle was 81,88. The result data of self-directed learning showed that there was an increase from the first cycle to the next cycle. In the first cycle, the average student's self-directed learning was 60,53, the second cycle was 65,29, and the third cycle was 68,12.
This study aims to describe the ability of mathematical problem solving in solving story problems in terms of the extrovert introvert personality types of SMP N 6 Rembang students on a two-variable linear equation system. This research is a qualitative descriptive study. The subjects in this study were students of class VIIIB SMP N 6 Rembang. Selection of Respondents used a purposive sampling technique consisting of three students for each personality type. Data collection techniques using questionnaires, tests, interviews and documentation. Data analysis techniques with data presentation steps, data reduction and conclusions. The results showed that the problem-solving ability for (1) extroverted students: were able to understand the problem and were able to explain again in their own language, were able to draw up a problem-solving plan, were able to carry out calculations and writing very neatly, were able to check the results obtained, ( 2) introverted students: have been able to understand the problem but have not been able to explain again with their own language, have been able to draw up a problem solving plan and are able to do calculations even though the writing is still messy, in general do not re-check the answers he has obtained.
<p>Tujuan dari penelitian ini untuk mengetahui, (1) Pengaruh model pembelajaran <em>Discovery Learning </em>dan model pembelajaran<em> Problem Based Learning </em>(PBL) pada materi pokok Kelarutan dan Hasil Kali Kelarutan (Ksp) terhadap prestasi belajar siswa. (2) Pengaruh kemampuan berpikir logis tinggi dan kemampuan berpikir logis rendah siswa terhadap prestasi belajar. (3) Interaksi antara model pembelajaran <em>Discovery Learning </em>dan<em> Problem Based Learning </em>(PBL) dengan kemampuan berpikir logis yang dimiliki siswa. Penelitian ini merupakan penelitian eksperimen dengan menggunakan rancangan penelitian desain faktorial 2x2. Populasi penelitian ini merupakan siswa kelas XI MIPA semester genap SMA Negeri 1 Sragen tahun pelajaran 2017/2018. Sampel pada penelitian ini adalah siswa kelas XI MIPA 1 dan XI MIPA 2 dengan teknik pengambilan sampel menggunakan <em>cluster random sampling</em>. Pada kelas eksperimen I diterapkan model pembelajaran <em>Discovery Learning </em>dan kelas eksperimen II menggunakan model pembelajaran <em>Problem Based Learning</em> (PBL). Teknik pengumpulan data adalah melalui teknik tes yang digunakan untuk mengambil data prestasi belajar pada aspek pengetahuan dan kemampuan berpikir logis dan teknik non tes digunakan untuk mengambil data pada aspek sikap dan aspek keterampilan. Pengujian hipotesis dalam penelitian ini menggunakan Analisis Variansi (ANAVA) dua jalan dengan sel tak sama yang digunakan untuk prestasi belajar aspek pengetahuan,dan uji statistik non parametrik Kruskal Wallis digunakan pada aspek sikap dan ketrampilan. Berdasarkan hasil penelitian diperoleh kesimpulan, (1) Penerapan model pembelajaran <em>Discovery Learning</em> dengan model pembelajaran <em>Problem Based Learning</em> (PBL) tidak menunjukkan perbedaan prestasi belajar siswa pada materi pokok Kelarutan dan Hasil Kali Kelarutan (Ksp) baik dari aspek pengetahuan, aspek sikap, maupun, aspek ketrampilan. (2) Kemampuan berpikir logis siswa berpengaruh pada prestasi belajar aspek pengetahuan dan tidak berpengaruh pada prestasi belajar aspek sikap dan aspek ketrampilan pada materi pokok Kelarutan dan Hasil Kali Kelarutan (Ksp). (3) Pada prestasi belajar siswa pada aspek sikap menunjukkan adanya interaksi antara model pembelajaran <em>Discovery Learning</em> dan model pembelajaran <em>Problem Based Learning</em> (PBL) dengan kemampuan berpikir logis siswa. Akan tetapi pada aspek pengetahuan dan aspek ketrampilan tidak menunjukkan adanya interaksi antara model pembelajaran <em>Discovery Learning</em> dan model pembelajaran <em>Problem Based Learning</em> (PBL) dengan kemampuan berpikir logis siswa.</p>
The STEM learning presented here is designed to facilitate the students to possess skills of imagination, collaboration, problem-solving, as well as critical and creative thinking which highly needed in this rapidly changing era. STEM learning aims to combine science, technology, engineering and mathematics by means of connections between subjects and real-world problems. In the empirical facts, however, STEM has only been practiced in natural science, and has not yet been applied to social science. This literature review analyzes the role of mathematics in developing science, both natural science and social science. In conclusion, mathematics can be played as a role in the development of science, both natural science and social science with various conditions.
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.
