This study aims to determine the application of multimedia learning modules assisted by tracker virtual laboratory (virlab) to train the verbal representation of students in class XI. This study uses observation and documentation methods to collect data. Observation instruments in the form of assessment sheets used to assess the level of representation students by using 2 classes where each class is filled by different educators. The first class is class XI IPA 1 (modelling class) and the second class is class XI IPA 2 (implementation class). The ability of verbal representations of students is assessed based on indicators on the assessment sheet. The results of the analysis show that verbal representation skills based on indicators clearly explain the problem, the ability to express opinions in sentence form, and describe definitions and terms of a concept in the implementation class obtain results that are better than the modelling classes. Whereas, the fourth indicator is explaining the results of the graph in the form of verbal representations in the modelling class obtained results that are better than the implementation class. These results indicate that application of multimedia learning modules assisted by tracker virlab application can be used to train verbal representation skills. © 2019 Published under licence by IOP Publishing Ltd.
