Low teaching quality is an issue, despite the critical role that good teachers play in dance education. When it comes to dance instruction, the standard model of education is inadequate and fails to meet expectations for excellent instruction. Consequently, this research suggests a method of evaluating instruction quality using online means. To begin, the instructional mode is used for content evaluation, and the indications are classified based on quality standards for instruction in order to mitigate the interfering component. Next, a teaching quality program is developed based on the impact of teaching mode on dance teaching quality, and the outcomes of this program are put into action. Thorough examination. According to MATLAB simulation, the online teaching method affects the quality of dance instruction and instruction quality to varying degrees depending on the assessment criteria. Compared to the standard instructional paradigm, the outcomes were superior.
