Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran inkuiri terbimbing (guidedinquiry) terhadap berpikir lateral siswa kelas VII SMPI As-Shodiq Bululawang.Metode penelitian ini adalah penelitian quasi eksperimental dengan rancangan pretest postest control group design. Populasi dalam penelitian ini adalah seluruh siswa kelas VII SMPI As-Shodiq Bululawang tahun pelajaran 2017/2018. Penentuan sampel dengan teknik random sampling (sampel acak) dan diperoleh jumlah sampel sebanyak 42 siswa dari 46 siswa. Nilai berpikir lateral diperoleh dari pretes dan postest berpikir lateral kemudian dicari selisihnya (N-gain). Kemudian data yang diperoleh di analisis dengan Uji Independent T Test dengan bantuan SPSS 17.0 for Windows pada taraf signifikan 5%. Berdasarkan hasil analisis menunjukkan bahwa ada peningkatan yang signifikan terhadap berpikir lateral siswa yang ditunjukkan oleh hasil Uji Independent T Test yakni nilai (sig.) lebih kecil dari 0,05 (sig. < 0,05) yaitu 0,000. Sehingga H0 ditolak dan H1 diterima, yang artinya ada pengaruh model pembelajaran inkuiri terbimbing (guided inquiry) terhadap berpikir lateral siswa kelas VII SMPI As-Shodiq Bululawang.

Abstract

The application of ethnomathematics-based cultural education that is integrated into learning can be through the development of learning instruments. Learning instruments consist of syllabus, learning material, student worksheets, learning resources, learning media, and evaluation tools. This studies discusses about worksheets, lesson plans, and syllabus in which ethnomatematics and character education have been included with purpose was to explain the development of syllabus, learning material, and mathematics student worksheets based on ethnomatematics in strengthening student character education.

Abstract

Algoritma Floyd-Warshall yaitu metode pemecahan masalah dengan memandang solusi yang diperoleh sebagai keputusan yang saling terkait. Algoritma yang ditemukan Warshall ini untuk mencari rute terpendek. Jenis penelitian ini adalah kualitatif deskriptif dengan pendekatan studi kasus. Studi kasus meneliti kasus tertentu yang ada di dalam masyarakat yang dilakukan secara mendalam untuk mempelajari latar belakang, keadaan dan interaksi yang terjadi. Hasil penelitian ini adalah mendapatkan rute terpendek menuju Air Terjun Waimarang dengan menggunakan Algoritma Floyd-Warshall di Sumba Timur. Tahap awal dari pencarian Rute Terpendek yaitu dengan mencari rute-rute yang menuju ke Air Terjun Waimarang dengan jarak, waktu dan biaya yang lebih sedikit. Titik-titik yang ada kemudian saling dihubungkan sesuai dengan jalan yang dilewati oleh kendaraan sehingga menjadi suatu jalur. Kemudian jalur yang sudah terbentuk dibuat matriks ketetanggaan dan dihitung menggunakan Algoritma Floyd-Warshall sehingga didapatkan pilihan jalur yang terpendek.

Abstract

This study aims to determine the effect of learning model based project on the creative thinking skills of grade VII students in SMP Tarbiyyatus Shibyan Tajinan. This research is a quasi experiment research with pre-test post test control group design. The population of this study subjects was 40 the seventh grade students of SMP Tarbiyyatus Shibyan Tajinan are divided into two classes. Class VII A as the control group and class VII B as the experimental group with each class number is 20 students. Data collection techniques in this study using the test in the form of essays as many as 3 questions that have been tested the validity and reliability. Hypothesis testing in this study using Independent Test T test for testing the difference score obtained by control class students and experiment class after learning (post tes). The result of the research showed that there is influence of model project based learning on creative thinking skill of class VII students in SMP Tarbiyyatus Shibyan Tajinan. The test result of Independent T Test found the value of 7,247 with sig (2-tailed) 0,000. Since the significance value (sig.) is less than 0.05 (sig. <0.05), it can be concluded that H0 is rejected and H1 accepted, meaning that there is an influence of the learning-model based learning to the students' creative thinking ability.

Abstract

The purpose of this research is to develope mathematical learning instrument based on ethnomatematics in strengthening students’ character education. The learning instruments consist of syllabus, lesson plan, and student worksheet. This research is a development study. This research was conducted in grade 8 of junior high school in Indonesia. This research was implemented in three stages, namely: define, design, and develop. The define phase includes the analysis of syllabus, syllabus, lesson plan, and student worksheet; the design stage includes the preparation of learning instruments draft and research instruments; the development stage includes the test of learning instruments, evaluation and perfection of learning instruments. The validation results of expert validators were as follows: syllabus device with a value of 4.62 with a very valid category, student worksheet instruments with a value of 4.59 with a very valid category, while the materials learning device with a value of 3.55 with a very valid category.
