Digitized Kotobee Interactive Learning E-Book: Its Effect on Academic Performance of Grade 9 Students in Science

The persistent threat of COVID-19 in the country poses an unprecedented challenge to basic education. The Department of Education (DepEd) has finally reopened schools for face-to-face classes, two years after the Philippine government had imposed lockdowns and rigorous safety health protocols to combat the spread of Covid-19. It made the Philippines a challenging year, especially for the academic sector, since educators and learners need to adjust to the usual normal education setting. This study explored the effectiveness of the digitized Kotobee interactive learning e-books in teaching Science to improve the student's academic performance. The study utilized the Quasi-experimental design 10 using the pretest and posttest non-equivalent group design. The digitized Kotobee interactive learning e-book, Kotobee Author and Reader Applications, pretest, posttest, and interviews were employed. The experimental group was given treatment, while the control group was exposed to a traditional teaching method. Findings indicated that control and experimental groups failed to reach the expected mean of 37.50, which is a passing standard of 75 percent during the pretest. A statistically significant difference in how well the students did on their science performance during the posttest than during the pretest was noted. Based on the results, the digitized Kotobee interactive learning e-book greatly influenced the performance of students in the experimental group. The study provides additional information that the intervention increased learner engagement in digital learning, improved the learners' e-book usage, and encouraged active class participation, effectively boosting students' learning gaps and performance in Science. Students had an exceptional learning experience when exposed to the digitized Kotobee interactive learning e-book.
