Nowadays, websites serve as a primary portal for knowledge sharing at schools. The web presence of schools impacts the knowledge interactions between teachers, from teachers to students, from students to teachers and between students. Due to poorly designed websites with problems such as ineffective navigation, misleading web content etc., low website user satisfaction has been reported. This ongoing study presents a research model that evaluates whether the user-centered design and usability of a school's website influences multi-faceted knowledge sharing interactions at schools. A questionnaire study was conducted with 335 primary school teachers at seven schools in Israel. The preliminary findings indicate that the website design and usability are significant factors that affect multi-faceted knowledge sharing interactions on school websites.
