Abstract
The objective of this research was to create and assess Digitized Instructional Materials (DIMs) utilizing Kotobee eBook Lessons to tackle the least learned competencies in Grade 2 English. Following the ADDIE model and adopting a quasi-experimental design, the study combined both quantitative and qualitative methods, incorporating expert evaluations, assessments from evaluators, and statistical tests like paired samples and one-sample t-tests.The DIMs were developed in accordance with DepEd Order No. 001, s. 2021, and received a Highly Valid rating concerning their content, language, and layout. Minor adjustments were implemented based on expert suggestions to improve both technical and grammatical precision.This research concentrated on enhancing student performance in three Most Essential Learning Competencies (MELCs): (1) recognizing common and proper nouns in simple sentences listened to; (2) discussing illustrations and predicting story content (EN2RC-Ia-1.3); and (c) identifying synonyms and antonyms (EN2V-Ia-5.2).The results indicated a significant advancement in studentsproficiencyfrom Proficient to Highly Proficientafter experiencing the digitized lessons. Statistical data corroborated the strong beneficial influence of the materials based on Kotobee.The findings of the study suggest that these digitized instructional materials serve as effective resources for improving elementary English education. It is recommended to incorporate such eBook-based tools into the curriculum to promote engaging, accessible, and learner-focused instruction.Keywords: Digitized Instructional Materials (DIMs), Kotobee, eBook, Most Essential Learning Competencies (MELCs), ADDIE Model
