<![CDATA[This research is a continuation of the research on developing a colloidal system e-module based on guided inquiry integrated virtual laboratory which has been tested for validity and practicality but has not been tested for effectiveness. The purpose of this study was to determine the effectiveness of using the e-module colloid system based on guided inquiry integrated virtual laboratory on the learning outcomes of class XI students at SMAS Nurul 'Ilmi. This type of research is quasi-experimental research using the One-Group-Pretest-Posttest design. The results of the t-test at a significant level of 0.05 are count (2.82) > table (1.68).
