Abstract
This study aims to determine the effectiveness of learning through video presentations and Whatsapp Group (WAG) on the topic of vector space during the Covid-19 pandemic. The learning system is carried out online using videos developed by researchers and shared via WAG. This research is action research conducted in two cycles with each cycle consisting of four meetings. The subjects of this research were 14-second semester students in the Mathematics Education Study Program Faculty of Teacher Training and Education, Universitas Mahasaraswati Denpasar who took Linear Algebra courses. The data collected in this study were the researcher's actions, the results of the evaluation, and student responses to the video presentation and WAG applied by the researcher. The results of this study indicate that the application of video presentations and WAG on the topic of vector space during the Covid-19 pandemic was classified as effective, because the average student score increased 12.9% and 1.3% respectively with the class average before the action 68, after the action in cycle I 76.79 and after the action in cycle II 77.79. Student responses regarding the application of video presentations and WAG were very positive. This learning strategy can be used as a solution during the Covid-19 pandemic, which requires students and lecturers to carry out the teaching and learning process from home.

Before the Covid-19 pandemic, learning was done face-to-face in class
The conclusion of this research is that learning using video presentations and WhatsApp groups on the topic of vector space during the covid-19 pandemic is effective, which is indicated by an increase in student learning outcomes from before this research was carried out and in each cycle
Summary
Several variations are made by educators to increase the effectiveness of learning, such as implementing 710|. Learning strategies that are tailored to the character of students, applying various learning media, such as power points, modules and others. The use of technology has been so massive in Indonesia, educators still use conventional learning approaches by utilizing textbooks and power points. This kind of learning was carried out by researchers before Covid-19 occurred. Many educators including lecturers had not prepared a proper learning system to be implemented. Lecture obtained a lot of information, including lecturers using group Whatsapp media to conduct learning, some lecturers used the Management Learning System (MLS)
