——Amidst this time of pandemic, planning an effective instruction demands every educator today to embrace the challenge of teaching in a new normal way. One of the strategies that may contribute to the effectiveness of teaching and learning is the use of FINER, an innovative self-learning material, in teaching permutations and combinations. This action research was theorized to determine the effectiveness of FINER in the Permutations and Combinations as an intervention in enhancing the problem-solving skills of Grade 10 students of Itawes National High School, using the quasi-experimental design particularly One-Group Pretest Posttest Research design. The participants of the study were thirty (30) grade 10 students who were classified as struggling learners based on the diagnostic test result. Findings of this study revealed that there is an improvement in the performance of the learners as shown in the computed values of mean and standard deviation. Anent to this, there is a significant difference between the mean pretest and posttest scores of the participants. Moreover, results revealed that there is a very large effect size of the intervention in the performance of the respondents. Hence, it is then recommended that Mathematics teachers may utilize FINER in teaching Permutations and Combinations and that school administrators should support the teachers on the preparation of contextualized and localized instructional materials to improve or enhance the performance of the learners in Mathematics. Nonetheless, the conduct of similar study was as well recommended for the enhancement of FINER. Keywords — FINER, Competencies, Permutations and Combinations
