Project-Based Learning Approach Based on Interpersonal Communication in Improving Vocational High School Students' Work Readiness

This research aims to analyze and evaluate the effectiveness of implementing a Project-Based Learning (PBjL) method based on interpersonal communication in improving the work readiness of vocational high school students. The Project-Based Learning method applied does not only focus on mastering theoretical knowledge but also on developing practical skills relevant to the world of work. This research uses a quantitative approach, with students given pre-tests and post-tests to measure the improvement in their work readiness after the implementation of PBjL. The research results show that there is a significant difference in students' work readiness after implementing interpersonal communication-based PBjL, with an average increase in post-test scores compared to pre-test scores. Interpersonal communication skills developed through PBjL, such as the ability to work in teams, share ideas, and resolve conflicts, have proven effective in preparing vocational high school students to enter the workforce. Therefore, interpersonal communication-based PBjL can be an effective learning model to improve vocational high school students' work readiness.
