The purpose of the study was to examine the effectiveness of multimedia integrated CIRC learning management plan on grade 2 students' spelling ability. The research employed a one-group experimental design in which a learning management plan based on CIRC principles, with the integration of multimedia, was used as the main intervention. The participants included 30 grade 2 students selected through clustered random sampling in a suburban province of Thailand. The study utilized a learning management plan comprising eight sub-lesson plans, as well as a spelling test of 30 multiple-choice items. The results analyzed using mean scores, standard deviation, percentages, learning management effectiveness (E1/E2), and a paired samples t-test. The findings revealed significant improvement in students' spelling abilities, with the effectiveness of the learning management plan reaching 84.22/88.77, exceeding the predetermined criteria of 75/75. This study contributes to educational research by demonstrating that multimedia-integrated CIRC is an effective approach for enhancing spelling skills in young learners.
