User Interface and User Experience Testing using the Lean UX method on the UT Course Assignment (TMK) website

Abstract

Technological developments have driven digital transformation in the world of education, including the use of websites as a medium to support learning. The Open University (UT) provides various online academic platforms, one of which is the Course Assignment (TMK) website, which is intended to support independent learning for students who do not attend tutorials. However, the TMK website still faces a number of complaints regarding its user interface (UI) and user experience (UX) design, which are considered to be unintuitive. Therefore, this study aims to evaluate and improve the quality of UI/UX on the TMK website using the Lean UX approach. The Lean UX method is applied in three main stages: Think, Make, and Check. Data collection was conducted through a USE Questionnaire (Usefulness, Ease of Learning, Ease of Use, and Satisfaction) distributed to 25 UT students. Initial testing results showed a usability rate of 71.44%, while after the redesign, the results improved to 106.44%. These findings indicate that after the redesign, there was a significant positive impact on the TMK website, namely an increase in user ease and user satisfaction with the TMK website. As result, this method is effective in producing a TMK website design that is more responsive, user-friendly, and supports the learning process optimally.
