Project-Based Learning (PBL) and Computational Thinking (CT) approach, offers ERD
problem solving efficiently. It aims to help teachers and students in learning ERD and
understand ERD concept and development interactively anywhere at any time. Evolutionary
prototyping methodology was adopted in developing this app. The evaluation of ERDeeds
shows that an average score of 76% was given based on the analysis using System Usability
