 The Web is used increasingly for informal learning which is more conversation based and learner-centred. Many intrinsic and extrinsic factors contribute towards retrieving information on demand. However, Web information retrieval (IR) has proved to be a challenging task due to the rapid increase in quantities of digitised information. Thus, retrieval time and learner attention should receive more emphasis to make Web IR more effective. This study identifies and tests an extended version of the Technology Acceptance Model (TAM) to identify the role of environment factors in effective Web resource usage. The study shows that the presence of environment factors lowers perceived access barriers, leading to more effective usage. Furthermore, the results suggest that extending the TAM to include perceived access barriers helps to explain the existence and application of intrinsic motivation factors leading to effective usage, providing key insights for website designers to re-evaluate their processes to incorporate environment factors.
