<![CDATA[This study aims to determine the comparison of economic learning outcomes using the Problem Based Learning, Project Based Learning and Discovery Learning learning models regarding to learning activities. The method used in this study is quasi-experimental with a comparative approach. Data collection through observation sheets, test questions and analyzed by t-test formula and ANOVA using manual calculations and SPSS. This research was conducted at SMAN 1 Sungkai Utara with a population of 4 classes and sample of 3 classes specified through Cluster Random Sampling. The results of data analysis show that F count F table or 11.396 3.09 means that there are differences in economic learning outcomes between students whose learning uses the Cooperative model type Problem Based Learning, Project Based Learning and Discovery Learning and F count F table or 47.778 3.09 means there is an interaction between learning model with student learning activities towards economic learning outcomes.Penelitian ini bertujuan untuk mengetahui perbandingan hasil belajar ekonomi dengan menggunakan model pembelajaran Problem Based Learning, Project Based Learning dan Discovery Learning dengan memperhatikan Aktivitas belajar. Metode yang digunakan dalam penelitian ini adalah eksperimen semu dengan pendekatan komparatif. Pengumpulan data melalui lembar observasi, soal test dan dianalisis dengan rumus t-test dan ANOVA menggunakan perhitungan manual dan SPSS. Penelitian ini dilakukan di SMAN 1 Sungkai Utara dengan populasi sebanyak 4 kelas dan sampel 3 kelas yang ditentukan melalui Cluster Random Sampling. Hasil analisis data menunjukkan F hitung Ftabel atau 11,396 3,09 berarti Terdapat perbedaan hasil belajar ekonomi antara siswa yang pembelajarannya menggunakan model kooperatif tipe Problem Based Learning, Project Based Learning dan Discovery Learning dan Fhitung Ftabel atau 47,778 3,09berarti Ada interaksi antara model pembelajaran dengan aktivitas belajar siswa terhadap hasil belajar ekonomi.Kata kunci: aktivitas, discovery learning, hasil belajar, PBL, PjBL]]>
