This proposal aims to evaluate the effectiveness of computer-assisted pronunciation training (CAPT) tools for vocational college students in Taiwan. The study will involve an experimental group that receives blended CAPT and traditional teaching, and a control group that receives only traditional teaching. Both groups will complete pre- and post-tests to measure pronunciation quality improvements. The proposal outlines the background, purpose, research question, methodology including participants, design, instruments, procedures, and statistical analysis that will be used.
