Measuring Students’ Satisfaction on an XAI-Based Mixed Initiative Tutoring System for Database Design

Abstract

This research proposes the development of an Entity-Relationship Diagram—PRO (ERD-PRO) to assist students in understanding the concept of developing Entity-Relationship Diagrams in designing a database. ERD-PRO is an Intelligent Tutoring System (ITS) that is built using a mixed-initiative approach to address the learning challenges by adopting Explainable Artificial Intelligence (XAI) concept to provide individualized and on-demand feedback and guidance. The effectiveness of ERD-PRO is tested on 25 participants from different educational institutions. Pre- development surveys are conducted to determine learning needs and post-development surveys are performed to measure the success. The results show that the design of ERD-PRO, guided by survey findings, successfully addresses key challenges in database design education. 65% of students agreed that the system’s explanation facilities effectively clarified difficult topics, and 90% expressed high satisfaction with the tool. The integration of XAI features within ERD-PRO has enhanced its ability to provide meaningful, scenario-based explanations, demonstrating its potential as an effective intelligent tutoring system. These findings validate the effectiveness of ERD-PRO in meeting its objectives and highlight its value in providing tailored explanations for database design instruction.
