Data collection is carried out through observation, interviews, and documentation, while data analysis uses an interactive analysis model that includes data reduction, data presentation, and drawing conclusions.

After the implementation of the Project Based Learning model using YouTube media, students are able to analyze elements of exposition text such as main ideas, facts or data, causes, and impacts better. The results of the writing assessment showed that most students obtained good to very good categories with an average class score of around 85. This finding indicates that the implementation of Project Based Learning assisted by YouTube media can create more active, contextual, and effective learning in improving students' expository text writing skills.]]>
