Tujuan dari penelitian ini yaitu untuk mengetahui tingkat kefektifan pembelajaran online Discovery Learning di Indonesia terutamanya. Keefektifan tersebut diteliti dari beberapa hasil penelitian yang sudh dipublikasikan melalui google.  Penelitian  ini  menggunakan  meta  analisis  yaitu mengkaji sejumlah jurnal dan posiding penelitian dalam masalah  yang  diambil  secara purposive berdasarkan tema penelitian. Kajian yang digunakan diambil dari basis data google sebanyak 5 jurnal dan 1 posiding dalam kisaran enam belas tahun terakhir (2020 - 2004). Analisis data menggunakan analisis kuantitatif denga uji Effect Size. Berdasarkan hasil penelitian dan pembahasan dalam penelitian ini, dari perhitungan uji Effect Size pada posiding untuk pretes, postes, pre-pos berturut-turut sebesar 0,58 ; 0,81 ; 0,68 sedangkan uji Effect Size pada jurnal untuk pretes, postes, pre- pos berturut-turut sebesar 2,76 ; 3,17 ; 2,95. Dapat disimpulkan bahwa uji Effect Size pada Jurnal  lebih besar dari pada uji Effect Size Posiding yang berarti peningkatan penguasaan konsep model Discovery Learning berbantuan e- learning sangat berpengaruh terhadap hasil belajar siswa model Discovery Learning pembelajaran daring.Kata kunci : Meta-Analisis, online Discovery Learning, Uji Effect Size.

The purpose of this research is to determine the level of effectiveness of online learning Discovery Learning in Indonesia especially. The effectiveness is examined from several research results that have been published on google. This research uses meta-analysis, which examines a number of journals and research posiding in the problem taken purposively based on the research theme. The study used was taken from the Google database as many as 5 journals and 1 posiding in the last sixteen years (2020 - 2004). Data analysis using quantitative analysis with the Effect Size test. Based on the results of the research and the discussion in this study, from the calculation of the Effect Size test on the posiding for the pretest, posttest, pre-post, respectively is 0.58; 0.81; 0.68 while the Effect Size test in the journal for pretest, posttest, pre-post is 2.76; 3.17; 2.95. It can be concluded that the Effect Size test on the Journal is greater than the Posiding Effect Size test, which means that the increase in mastery of the concept of the Discovery Learning model assisted by e-learning greatly affects student learning outcomes in the Discovery Learning model of online learning.
