Abstract
The flexible learning modality empowers both learners and teachers to adjust to a variety of learning styles, preferences, and circumstances. This approach acknowledges the diverse needs of students, offering a range of alternatives beyond the traditional, one-size-fits-all educational model. In this study, a flexible learning material was designed as a strategic innovation to enhance the mathematical skills of Grade 10 students at Esperanza National High School for the school year 2022-2023. The primary tool used was adapted from the Grade 10 Mathematics Self-Learning Modules provided by the Department of Education, focusing on the Quarter 1 lessons. These materials were designed to target key skills, including comprehension, computation, vocabulary, and the recognition of mathematical symbols. The research employed a quantitative methodology, specifically a quasi-experimental design. The findings revealed that students in the experimental group, who were exposed to the blended learning modality using the flexible learning materials created by the researcher, showed significant growth in their problem-solving abilities and overall mathematical competence. In contrast, students in the control group, who continued with conventional learning methods, demonstrated little to no improvement. The results highlight that learner engaged in the blended learning modality outperformed their peers, scoring considerably higher than those taught through traditional methods. Overall, the flexible learning modality proved to have a highly positive impact on students’ mathematical skills, promoting adaptability and resilience in problem-solving.
