The T-test is conducted to determine the significance of the improvement in the experimental class compared to the control class. The assessments for both groups will include pre-and post-assessments to evaluate the changes in their listening and speaking skills. The control class used a traditional textbook without a QR code. The experimental class used an English textbook published by Erlangga, which is enriched with a QR code connected to multimedia resources for listening and interactive exercises for speaking practice. Sixty students in an Islamic elementary school as the participants will be randomly assigned to an experimental class and a control class. This study used a quasi-experimental design with pre-tests and post-tests within experimental and control classes to evaluate the effectiveness of QR-code content in improving language skills. This quantitative study examines the impact of implementing QR codes in English textbooks on students' listening and speaking skills.
