Abstract

This study aims to examine the effectiveness of Integrated Content and Language Learning (CLIL) online assisted by virtual laboratory on students’ science process skills. The science process skills studied include the process of observing, classifying, communicating, measuring, predicting and inferring. This experimental research was conducted on students at Cahaya Rancamaya High School who used English as the medium of instruction in science learning. Student selection is done by purposive sampling. Data is collected through tests of science process skills. The results of the N-gain percentage analysis are 62% and in the medium category. The results show that CLIL online assisted by virtual laboratory is effective in improving students’ science process skills in acid-base material.
