THE EFFECTIVENESS OF PROJECT-BASED LEARNING MODELS IN IMPROVING UNDERSTANDING OF STATISTICAL CONCEPTS

Every student in higher education will learn about statistics. Statistics is knowledge data collection, classification, presentation, processing, drawing conclusions, and making decisions based on certain problems. Because statistics are related to sample data, it necessary the ability interpret, understand, make good data. Project-Based Learning very suitable be applied solve complex problems a creative, collaborative, independent way like this course. This research analyze effectiveness of PjBL learning improving understanding statistical concepts. The subjects were seventy students who took courses at Mathematics Education Study Program, Bengkulu University 2021. type quasi-experimental design using one-group pretest-posttest design. instrument was test sheet for concept statistics, including choose analysis, process interpret results. analyzed t-paired N-Gain score. Based results study, can concluded that application quite effective increasing students' concepts University, especially mathematics study program. Students' after model than before applied.Setiap mahasiswa di perguruan tinggi pasti akan mempelajari tentang statistika. Statistika merupakan pengetahuan mengenai pengumpulan klasifikasi penyajian, pengolahan, penarikan kesimpulan, dan pengambilan keputusan berdasarkan masalah tertentu. Dikarenakan statistik berkaitan dengan sampel maka diperlukan kemampuan pemahaman dalam menafsirkan, memahami serta membuat yang baik terhadap tersebut. Model Project sangat cocok diterapkan untuk memecahkan kompleks cara kreatif, kolaboratif, mandiri seperti pada mata kuliah ini. Penelitian ini dilakukan menganalisis efektifitas pembelajaran meningkatkan konsep Subjek penelitian yaitu tujuh puluh mengambil statistika Program Studi Pendidikan Matematika Universitas tahun Jenis adalah quasi eksperiment menggunakan rancangan one group pretest-postest Instrumen berupa lembar tes statistika, meliputi memilih analisis pengolahan menginterpretasikan hasilnya. Data dianalisis uji skor N-Gain. Berdasarkan hasil dapat disimpulkan bahwa penerapan cukup efektif khususnya program studi pendidikan matematika. Pemahaman setelah lebih dibandingkan sebelum PjBL.
