The assessment by education practitioners yielded a percentage of 97%, classified as “highly practical.” The effectiveness test results indicated an improvement in student learning outcomes, as evidenced by the average pretest score of 50 increasing to 92.87 on the posttest. The N-Gain calculation yielded a score of 0.77 (high category) with an effectiveness percentage of 77.42% (effective category). Thus, the e-dictionary learning tool supported by the Canva and Book Creator applications is deemed valid, practical, and effective, making it suitable for use as a learning tool to improve elementary school students’ mastery of English vocabulary.]]>
