摘要:More and more LEGO NXTs are applied to combine with different courses for designing multimedia instructional materials. Therefore, understanding the factors affecting the teachers’ intention of using Lego NXT has been an eager research issue. The purpose of the current research is to explore the teachers’ intention of using Lego NXT in primary school. A model combining the Technology Acceptance Model (TAM) as well as system and participant characteristics is proposed. Data were collected from forty seven primary school teachers in Kaohsiung and Pingtung county. Structural Equation Modelling (SEM) is used to test the hypothesis.
