However, the constructivism learning model is still rarely applied, especially in mathematics learning so that the learning objectives are not achieved properly. This research was conducted to obtain comprehensive information on how constructivism theory is used in online mathematics learning and the obstacles faced. This can be useful to find out good new adaptations in implementing online mathematics learning in the future. In addition, it can be useful as an evaluation material for the application of constructivism theory in online mathematics learning in the future. This research uses descriptive analysis method with literature study technique. The constructivism theory referred to in this study is a constructivist learning theory that has been explored in the application of online mathematics learning into four parts, namely: a learner-centered learning environment, a knowledge-centered learning environment, an assessment-centered learning environment, and an assessment-centered learning environment. community-centred learning.Keywords: constructivism, learning mathematics, daring AbstrakTeori belajar konstruktivisme sangat relevan diterapkan dalam pembelajaran di Indonesia karena mempunyai keunggulan yang dapat digunakan sebagai metode belajar yang inovatif.

The research was carried out at SMP Negeri 1 Botupingge in the odd semester of the 2021/2022 academic year. This type of research is an experimental research using the quasi-experimental method. The research design used was a non-equivalent control group design involving 2 classes as the research sample, namely the experimental class and the control class which were given different treatment. The sample was selected using a purposive sampling technique with the number of students in each class as many as 25 students. The data collection technique used is the provision of tests including pre-test and post-test in the form of essays to obtain data on student learning outcomes. The results of the analysis with the t-test at a significance level of 0.05 indicate a difference between the learning outcomes of students who are taught using Edmodo and Google Meet. The average student learning outcomes using Edmodo is 77.64, which is higher than the average student learning outcomes using Google Meet at 67.72. Based on the results of the average N-Gain calculation, the gain value is 0.61. This shows that the effectiveness of using the Edmodo platform is in the medium category.
