Listen to the article here



In today’s educational landscape, the demanding nature of manual assessments has become a significant challenge for lecturers at the Institute of Technical Education (ITE). This case study explores the transformative solution provided by integrating Artificial Intelligence (AI) through Noodle Factory's AI teaching assistant, Walter, which has revolutionized teaching practices by streamlining assessment processes and personalized learning, ultimately enhancing the educational experience for both educators and students alike.

The Challenge: The Burden of Traditional Assessment Methods

Lecturers at ITE faced a major challenge: excessive time spent on administering and marking assessments. This traditional approach not only hampered their efficiency but also limited their ability to provide personalised feedback to their students.

"The manual process was time-consuming and exhausting, leaving less room for one-on-one sessions with students in need."


This bottleneck in the educational process underscored the need for an innovative solution that could alleviate the administrative burden and enhance learning outcomes.
