Abstract

Penelitian ini bertujuan untuk mendeskripsikan kemampuan pemecahan masalah matematika, self-efficacy siswa dan hubungan antara kemampuan pemecahan masalah dan self-efficacy siswa kelas VIII SMP Negeri di Kabupaten Ciamis. Penelitian ini adalah penelitian survei. Subjek penelitian terdiri dari 389 siswa kelas VIII SMP Negeri di Kabupaten Ciamis yang berasal dari 13 sekolah dengan kategori strata tinggi, sedang dan rendah. Sampel dalam penelitian ini ditentukan dengan stratified proporsional random sampling. Hasil penelitian menunjukkan bahwa 389 siswa yang dijadikan subjek penelitian memiliki kemampuan pemecahan masalah dalam kriteria rendah. Faktor-faktor yang menyebabkan keadaan tersebut diantaranya adalah siswa kurang memahami informasi pada soal, siswa kurang mampu membuat model matematis, dan siswa kurang teliti dalam menyelesiakan soal. Rata-rata self-efficacy siswa berada pada kriteria sedang, yaitu 91,17. Hubungan kemampuan pemecahan masalah matematika dan self-efficacy siswa termasuk kategori sangat rendah karena nilai r sebesar 0,104. An Analysis of Mathematics Problem Solving Ability and Self-Efficacy Students of Junior High School in Ciamis Regency AbstractThis study aims to describe the mathematics problem-solving ability, self-efficacy of students and the relationship between the problem solving and self-efficacy of the grade VIII students of the junior high school in Ciamis Regency. This study was categorized as survey research. The research subjects were 389 junior high school grade VIII in Ciamis Regency from 13 schools which were categorized as high, moderate and low schools. The research sample was selected by means of the stratified proportional random sampling technique. The results of the study are as follows, 389 students as the research subject have low criteria in problem-solving ability. Factors that cause this situation, such as students are less understanding of existing information on the problem, students are less able to make mathematical models, and students are less thorough in problem-solving. The average of students’ self-efficacy was at moderate criteria, 91.17. The relationship between problem-solving ability and self-efficacy of students was at very low criteria because of the r-value of 0.104.

Abstract

Penelitian ini bertujuan untuk menghasilkan bahan ajar statistika dan peluang berbasis multiple intelligences berorientasi pada prestasi belajar, kemampuan pemecahan masalah dan rasa ingin tahu siswa SMP kelas VII yang valid, praktis, dan efektif. Bahan ajar yang dihasilkan memuat konteks, ilustrasi, dan aktivitas yang bervariasi. Terdapat bagian peta konsep, tokoh kita, cari tahu, ingat kembali, pahami masalah, mengamati, gali informasi, menalar, diskusi dan berbagi, pahami contoh, motivasi, melatih diri, pecahkan masalah, proyek mandiri, pecahkan teka-teki, ruang ekspresi, dan uji kompetensi pada struktur bahan ajar. Prosedur pengembangan menggunakan 5 tahapan yaitu: (1) Analisis, (2) Perancangan, (3) Pengembangan (4) Implementasi, dan (5) Evaluasi. Subjek uji coba adalah siswa kelas VIIA SMP Negeri 4 Kalibening, Kabupaten Banjarnegara yang terdiri atas 26 siswa. Instrumen  penelitian yang digunakan terdiri atas lembar validasi, lembar observasi keterlaksanaan pembelajaran, lembar penilaian kepraktisan oleh siswa, lembar penilaian kepraktisan oleh guru, dan instrumen keefektifan bahan ajar. Analisis data dilakukan dengan mengkonversi total skor data kuantitatif yang diperoleh menjadi data kualitatif skala lima. Hasil penelitian ini menunjukkan bahwa bahan ajar memenuhi kriteria valid, praktis, dan efektif ditinjau dari prestasi belajar, kemampuan pemecahan masalah dan rasa ingin tahu siswa.Kata Kunci: pengembangan; bahan ajar; multiple intelligences; prestasi belajar; kemampuan pemecahan masalah; rasa ingin tahu Developing Statistics and Probability Teaching Material Based on Multiple Intelligences and Oriented to the Achievement, Problem Solving, and Curiosity AbstractThis research aims to produce teaching material based on multiple intelligences and oriented to the learning achievement, problem-solving, and curiosity of grade VII Junior High School Students that is valid, practical, and effective. The teaching material that contains contexts, illustrations, and various activities. There is part of a map the concept, our figure, find out, remember back, understand the problem, observation, dig it information, reasoning, discussion and share, understand example, motivation, train themselves, problem-solving, project self-sufficient, riddles solving, the expression, and the test competency on the structure of teaching material. The quality is determined based on Nieveen criteria, including validity, practicality, and effectiveness. This study was a research and development using Branch (ADDIE) model which consisted of 5 (five) steps, that is: (1) Analysis, (2) Design, (3) Development, (4) Implementation, and (5) Evaluation. The subject of this research were 26 students of grade VIIA SMP Negeri 4 Kalibening-Kabupaten Banjarnegara.

Abstract

Penelitian ini bertujuan menelaah peranan pembelajaran open-ended dan tingkat kemampuan awal statistik matematis mahasiswa terhadap pencapaian kemampuan penalaran statistik dan kemampuan berpikir kreatif matematis ditinjau secara keseluruhan dan pada tingkat kemampuan awal statistik matematik siswa (Tinggi, Sedang, Rendah). Berdasarkan hasil temuan dicari asosiasi kemampuan penalaran statistik matematis dan kemampuan berpikir kreatif matematis mahasiswa jurusan matematika di kota Cimahi. Penelitian ini merupakan penelitian eksperimen dengan desain kelompok kontrol dan postes. Populasi dalam penelitian ini adalah  seluruh  mahasiswa  jurusan  matematika di Kota Cimahi, sampelnya adalah mahasiswa semester dua dari salah  satu  perguruan tinggi di  Kota  Cimahi dan dipilih  dua kelas mahasiswa semester dua secara acak kelas yang ada. Tes kemampuan penalaran statistik, berpikir kreatif dan reflektif matematis mahasiswa masing-masing disusun mengacu pada kemampuan penalaran statistik matematis dan berpikir kreatif matematis serta  pedoman  penyususunan  tes  yang  baik.  Hasil penelitian menunjukkan bahwa (1) Kemampuan   penalaran   statistik   matematis  m a h a siswa    yang    memperoleh   pendekatan pembelajaran  open-ended  lebih  baik  daripada  yang  memperoleh  pembelajaran biasa. (2) Terdapat perbedaan yang signifikan kemampuan penalaran statistik matematis mahasiswa pada ketiga kategori TKASM (baik, sedang dan kurang) pada taraf signifikansi 5%. (3) Kemampuan berpikir kreatif matematis m a h a siswa yang memperoleh pendekatan pembelajaran open-ended  lebih  baik  daripada  yang  memperoleh  pembelajaran biasa. (4) Terdapat perbedaan yang signifikan antara kemampuan berpikir kreatif matematis mahasiswa pada TKASM Tinggi terhadap TKASM Sedang pada taraf signifikansi 5%. A Comparison of Statistics Learning Through CTL and Problem-Posing Approach in Terms of Learning Achievement and Interest in Learning Mathematics AbstractThis research aim s to describe the effectiveness of statistics learning through the CTL approach and problem posing approach in terms of learning achievement and interest in learning mathematics and to investigate which approach is more effective in learning mathematics for Vocational School students. This research is a quasi-experimental research using the pretest-posttest non-equivalent group design. The research population comprised all year XI students of SMK Negeri 5 Yogyakarta. From the population, two classes were randomly selected as the research sample. To test the effectiveness of statistics learning through the CTL and problem-posing approach, one sample t-test was used in the aspect of learning achievement and a proportion test on the aspect of interest in learning. The data were analyzed using the T2Hotelling’s test to compare the effectiveness of the CTL approach and problem-posing approach. If differences in effectiveness were found, then further study of t-univariate was done to determine certain variables that contributed to the overall difference. The results show that: (1) statistics learning through the CTL approach is effective in terms of learning achievement; (2) There is a significant difference of students' mathematical statistical reasoning ability in the three categories of TKASM (good, medium and low) at significance level of 5%. (3) The ability of students' mathematical creative thinking to get an open-ended learning approach is better than those who get regular learning. (4) There is a significant difference between students' mathematical creative thinking ability in TKASM Tinggi to TKASM Sedang at the level of significance of 5%.
