摘要：The usability of the web pages is assessed using some statistical models. Researchers argue that many usability results and recommendations lack empirical and experimental data. Universities web pages are chosen as subjects for this work. Series of experiments have been conducted to investigate into the usability and design of the universities web pages. Prototype web pages have been developed according to the structured methodologies of web pages design and development. Four universities web pages were evaluated together with the prototype web pages using a questionnaire which was designed according to the Human Computer Interactions (HCI) concepts. The data collected was analyzed using correlation and regression models. The correlation analysis showed that there were significant positive and negative correlations between many items. The regression analysis revealed that the most significant factors (items) that contributed to the best model of the universities web pages design and usability were: multimedia in the web pages, the web pages icons (alone) organization and design, and graphics attractiveness. The results showed some of the limitations of some heuristics used in conventional interface system design and proposed some additional heuristics in web pages design and usability.
