MDAS (Multiplication, Division, Addition, Subtraction)-IT-ALL: An Android-Based Supplementary Tool in Math 3

Aim: This study designed and developed an android-based math application to improve the numeracy skills of Grade 3 learners in the Paracale District, Division of Camarines Norte.It aimed to address gaps in numeracy skills, particularly for learners identified as needing major support, based on the Albay Numeracy Assessment Test (ALNAT) results. Methodology:The study used a descriptive-developmental approach.It involved 303 Grade 3 learners from 24 elementary schools in the district and 36 evaluators including teachers, master teachers, and IT experts.The application was designed following the ADDIE model, focusing on stages of analysis, design, development, implementation, and evaluation.The effectiveness of the app was measured through pre-and post-test results, as well as evaluations based on the LRMDS Evaluation Rating Sheet and ISO 9126 Software Quality Standards.Results: The post-test results indicated a significant improvement in the numeracy skills of learners after using the android-based math app.Furthermore, the application was rated highly in terms of content, instructional, and technical quality by the evaluators.The study showed that the app was an effective tool for improving basic numeracy skills among Grade 3 learners. Conclusion:The study successfully developed and implemented an android-based math application that significantly improved numeracy skills among learners needing major support.The application was positively evaluated by educators, and its effectiveness was demonstrated through improved post-test results.
