摘要：AbstractAs a result of our research we have become increasingly aware of the relevance of visual design in understanding learners’ attitudes towards the use of virtual tools. Likewise, perceived usefulness is an essential antecedent of the cumulative impressions of, and preferences for, such tools. Therefore, the aim of this study is to investigate the main effects of visual design and usefulness on learning and productivity in the domain of web-based educational tools. Structural Equation Modelling, specifically Partial Least Square (PLS), is proposed to assess the relationships between the constructs. Visual design and usefulness have a significant effect on the learner's perception of the extent to which needs, goals and desires have been fully met and, by extension, learning performance. Furthermore, higher expressive aesthetics reduces the impact of classical features on satisfaction.
