TL;DR
It is concluded that simple language, predictable structure, and iterative feedback can significantly improve usability, maintainability, and trust in content-heavy educational websites across diverse institutional contexts.
Abstract
This article focus on the user-centered redevelopment of an academic content website designed to help students, instructors, and administrative users
find course information quickly and confidently. A mixed-method evaluation compared an earlier version with a standardized, template-based
redesign emphasizing clear information architecture, consistent section order, lightweight interactions, accessibility, and mobile responsiveness.
Seventy-two participants completed realistic tasks on desktop and mobile devices; metrics included task completion, mean task time, navigation
errors, and perceived ease of use, supported by open comments. Results showed substantial gains after redevelopment: completion rose from 76% to
92%, average task time fell from 4.8 to 2.9 minutes, navigation errors dropped by 41%, and positive ease-of-use responses increased from 61% to
88%. Qualitative feedback highlighted improved confidence, faster scanning, and better cross-page consistency. The study concludes that simple
language, predictable structure, and iterative feedback can significantly improve usability, maintainability, and trust in content-heavy educational
websites across diverse institutional contexts.
Educator access to high-quality Evidence-Based Practices is often hindered by professional development (PD) websites that are overwhelming, difficult to navigate, or time-consuming to use. This study explored using an AI chatbot to improve the usability and navigability of finding relevant content on a PD website. An e...

Policy makers and educators have increasingly recognized the importance of K-12 teacher professional development (PD) in computer science (CS) to foster student growth and academic achievement. In this exploratory mixed-methods study (focus groups n=23, survey n=661), we addressed two research questions: (1) What featu...

This study aims to evaluate the usability, user experience, and cognitive load of the AIRAF interface using a User-Centered Design (UCD) approach through two iterative evaluation phases. In the first evaluation phase (UE1), eight undergraduate students completed a series of structured interaction tasks using Maze and s...
Within the limits of this small-scale classroom evaluation, the findings suggest that rubric-guided LLM scoring may support formative assessment in mobile classrooms, provided teacher oversight is maintained for borderline cases.
