Abstract
Instructional materials play a significant role in developing mathematical skills and creativity. The choice of instructional materials can greatly impact a student’s understanding, engagement, and overall performance in mathematics. This study developed and validated the Cartoon-based Module (CBM) to enhance students' mathematical creativity. The acceptability of the module was assessed in terms of content, language, design and layout. Evaluated by five experts with a mean of 3.81, 3.76, and 3.63, it was interpreted as highly acceptable. The research methodology is aligned with the quantitative design, particularly quasi-experimental research. The study’s respondents are 90 Grade 7 students of Isulan National High School divided into control and experimental groups. A researcher-made test questionnaire is used to assess mathematical creativity among students. The findings based on the t-test result in the experimental group with a mean gain score of 37.17 and a standard deviation of 14.19, and the control group resulted in a mean gain score of 25.85 with a standard deviation of 15.30. The t-test computed value equals 3.64, which is greater than ttab (0.05) = 2.002 indicating that the CBM in mathematics education significantly improved students' learning outcomes. The module demonstrated its effectiveness in enhancing mathematical knowledge and skills, increasing students' mathematical creativity.
