Utilization of Locally-Based Reading Resources in Improving Science Concept Comprehension among Grade 9 Learners

The study aimed to assess the effectiveness of locally-based reading resources (LBRR) on the comprehension of science concepts among ninth-grade learners at Odiongan National High School. A quasi-experimental design was employed to achieve this, wherein two groups were tested using a non-equivalent pre- and post-test setup. The sample comprised ninth-grade learners from Odiongan National High School, selected through purposive sampling. Two sections were chosen, with 31 students in each group. The samples were selected due to their similar average grades in Science during the second quarter of the school year 2023-2024. Data collection utilized a teacher-made test, validated and reliability-tested administered to the treatment group (exposed to LBRR) and the control group (exposed to DepEd Learning Material). Statistical analysis involved using mean and standard deviation, with a one-way analysis of covariance (ANCOVA) employed to assess the effect of LBRR as an intervention. The findings indicated that post-test results demonstrated a notable difference, with the treatment group showing a higher mean score. The effect size was found to be medium, further supporting the significance of the results. The study concluded that LBRR effectively enhances science concept comprehension among ninth-grade learners at Odiongan National High School based on these outcomes. This conclusion was drawn from the observed improvement in post-test scores following the implementation of LBRR.
