Practicality Tests of Teaching Materials on Series and Sequences using Canva Media through Realistic Mathematical Approach

This research is a study that focuses on the development of realistic-based mathematics teaching materials on high school students' mathematical communication skills on sequences and series material. Research and Development (R&D) is the research used, the model to support this research is using the ADDIE model which has 5 stages in its application, the stages of analysis, design, development, implementation, and evaluation. However, the discussion in this article only extends to the practicality test which is the advanced stage of the Development stage. The instrument used in this study was a questionnaire (validation and response). Validation was carried out by material experts, ICT experts, and responses were obtained from teachers and students. Material expert validation results reached a percentage of 85.10% of the average interpretation of "very feasible", ICT expert validation results were at 83.80% with the final statement "Very Feasible", student and teacher responses in the product test were obtained successively of 85.62% ("Very Practical") and 94.38% ("Very Practical"), the conclusion is that the mathematical material based on canva-assisted realistic is "Very Appropriate" and "Very Practical" in use for learning mathematics in senior high school.
