This study aims to determine the effect of using the Cisco Webex application in onlinephysics learning on the material of quantities and units on student learning outcomesat SMA Negeri 7 Pontianak. This research is a quantitative research. The datacollection technique was carried out using pretest-posttest questions. The experimentaldesign used is a pre-experimental design with a one group pretest-posttest design. Thesample in this study was 33 students of class X MIPA 1 for the academic year2021/2022. Statistical analysis used was Shapiro Wilk test to test the normality of thedata, and Wilcoxon signed Rank to test the hypothesis. Based on the student learningoutcomes data, it shows that the Z value (Wilcoxon Signed Rank Test) is -3.244 with ap value (Asymp. Sig 2 tailed) of 0.001. Thus, it can be concluded that there is an increasein student learning outcomes in the material of quantities and units in online learningat SMA Negeri 7 Pontianak after learning using the cisco webex application. So it ishoped that the results of this study can improve the quality of online learning during theCOVID-19 pandemic.Keywords: Cisco Webex Application, Learning Outcomes, Quantities and Units.
