Abstract
The study aimed to develop, validate, and determine the level of effectiveness of the competency-based infographic materials in Science for Grade 10 students. The developed competency-based infographic materials in Science contains the selected least-mastered topics and competencies under the existing module provided by DepEd. It was conducted during the School Year 2023-2024 at Teresa Sub-Office which includes Abuyod National High School, Pantay Integrated High School, and Teresa National High School. It used descriptive and experimental designs involving two groups, Grade 10- Cypress as control group (unexposed) and Grade 10- Ebony as experimental group (exposed). They were chosen using the purposive sampling. Twenty-six (26) public Secondary Science teachers in the three public schools in Teresa Sub-Office were the respondents of the study in the validation of the acceptability of the developed competency-based infographic materials in Science for grade 10 students. Based on the findings, the study concluded that the developed competency-based infographic materials in Science for grade 10 students is acceptable and may be used as supplementary materials or teaching aids. Moreover, the findings on the level of performance of the grade 10 students in exposed and unexposed group increased their mean scores. And the overall findings revealed that there is a significant difference in level of performance of the grade 10 students as revealed in their posttest scores of the exposed and unexposed group. The study concluded that the developed competency-based infographic materials in Science for grade 10 students is acceptable and may be used as supplementary teaching aids. The result of the test after exposure to the competency-based infographic materials is significantly higher than the posttest of the unexposed group.
