**Abstract:** This research explored the integration of dual coding theory and modern computer technology with symmetry into a vocabulary class to improve students' learning attitude and effectiveness. Three research questions are addressed in this research on the effects of computer-assisted learning based on dual coding theory (DCT). This experimental research was carried out in a high school in a remote rural area in China. The study was conducted in two parallel classes (the experimental and the control) in Grade 8 with a total of 88 students. Our research methods included pre- and post-test, questionnaires, and an interview with symmetry as the focus to obtain the results as follows: (1) Using the integration of computer assisted language learning (CALL) and DCT to effectively improve students' learning attitude, (2) transforming students' traditional learning methods into the dual coding method, and (3) enhancing students' vocabulary learning effectiveness.
