The purpose of this research is to analyze and describe the video conferencing application technology-based learning via zoom cloud meeting to improve students' mathematical communication ability based on the perspective of educators or teachers. The research was conducted using a qualitative descriptive method with an emphasis on needs analysis. Techniques of data collection were carried out with several instruments including interviews, documentation, questionnaires, and tests related to students' mathematical communication ability given to several students with the assistance of their respective teachers. The results of interviews and initial observations in this research indicate that 80% of teachers still use assignments as tools to determine students' mathematical communication ability, and 67% of students' mathematical ability has decreased compared to that of prior to the pandemic, so a learning model is needed in accordance with current educational conditions, particularly in improving students' mathematical communication ability. Therefore, the selection of the application of a problem-based learning model with a realistic mathematical approach in zoom cloud meeting-based learning is expected to improve the communication ability of elementary school students.
