An analysis of creative thinking ability and learning interest of students of junior high school in solving open ended problem with CTL approach AbstractThis research aimed to analyze the categories and aspects of creative thinking ability and in student learning interest, the increase of students learning interest, and the better learning between CTL approach using open ended questions with CTL approach in terms of the ability to think creatively and interest in learning of students of Junior High School. This research was a quasi-experimental research with pretest-posttest non-equivalent comparison-group design. The research population comprised all year VIII students of SMP Negeri 1 Miri, Sragen Regency, Indonesia. From the population, two classes were randomly selected as the research sample. The instruments used were in the form of creative thinking ability tests and questionnaires for students’ interest in learning mathematics. To analyze the categories and aspects of creative thinking abilities and interest in learning, descriptives statistical analysis was used, to analyze the increase of students’ interest, the data were analyzed using paired t-test at 5% significance level. As for comparing better learning between CTL approach using open ended questions with CTL approach, the data were analyzed using MANOVA followed by t-test independent to determine which approach was better. The results showed that the category of creative thinking abilities in the classroom CTL using open ended questions in the high category, while in the CTL approach class was in middle category, for the category of interest in learning, either with CTL approach using open ended questions or as with the CTL approach, students were of the high category, categories of creative thinking abilities, for both classes have the highest percentage on the aspect of smoothness, by providing CTL approach with open ended questions and CTL approach, students’ interest increased significantly and CTL approach with open ended questions was better than CTL approach in terms of students' ability to think creatively, and CTL approach with open ended questions was not better than CTL approach in terms of student interest.
Tujuan penelitian ini untuk mendeskripsikan keefektifan pembelajaran berbasis proyek pada materi statistika ditinjau dari prestasi belajar, kemampuan berpikir kritis, dan kepercayaan diri siswa SMP kelas VII. Pembelajaran berbasis proyek terdiri dari enam langkah yaitu: (1) penentuan proyek; (2) perancangan langkah-langkah penyelesaian proyek; (3) penyusunan jadwal pelaksanaan proyek; (4) penyelesaian proyek dengan fasilitasi dan monitoring guru; (5) penyusunan laporan dan presentasi/publikasi hasil proyek; dan (6) evaluasi dan hasil proyek. Populasi dalam penelitian ini adalah siswa kelas VII SMPN 1 Yogyakarta. Instrumen yang digunakan adalah tes prestasi belajar, tes kemampuan berpikir kritis, angket kepercayaan diri, dan lembar observasi keterlaksanaan pembelajaran. Uji hipotesis menggunakan uji proporsi Z pada taraf signifikan 95% (α = 5%). Berdasarkan hasil uji hipotesis diperoleh proporsi siswa yang prestasi belajarnya telah mencapai KKM lebih dari 75%. Proporsi siswa yang memiliki kemampuan berpikir kritis dan kepercayaan diri pada kategori minimal “baik” lebih dari 75%. Dengan demikian dapat disimpulkan bahwa pembelajaran berbasis proyek efektif ditinjau dari prestasi belajar, kemampuan berpikir kritis, dan kepercayaan diri siswa. The effectiveness of project-based learning viewed from students’ learning achievement, critical thinking skill, and self-confidenceAbstractThe purpose of this study was to describe the effectiveness of project-based learning in statistical material viewed from learning achievement, critical thinking skills, and self-confidence of seventh-grade junior high school students. Project-based learning consists of six steps: (1) determining the project; (2) designing project completion steps; (3) preparing the project implementation schedule; (4) completion of the project with facilitation and monitoring from the teacher; (5) preparation of reports and presentation/ publication of project results; and (6) evaluation and results of the project. The population in this study was seventh-grade students of SMP 1 Yogyakarta, Indonesia. The instruments used were a learning achievement test, a critical thinking ability test, a self-confidence questionnaire, and an observation sheet of learning accomplishments. Hypothesis testing uses the proportion Z test at a significant level of 95% (α = 5%). Based on the results of the hypothesis test, the proportion of students who have learning achievement reached KKM was more than 75%. The proportion of students who have critical thinking skills and self-confidence in the minimum category of "good" was more than 75%. Thus it could be concluded that project-based learning was an effective view from students’ learning achievement, critical thinking skills, and self-confidence.
