Lecture Notes in Computer Science- P6:This year, we received about 170 submissions to ICWL 2008. There were a total of 52 full papers, representing an acceptance rate of about 30%, plus one invited paper accepted for inclusion in this LNCS proceedings. The authors of these accepted papers came from many different countries. | Richness Versus Parsimony Antecedents of Technology Adoption Model 15 5 Discussion A fair comparison of models or theories includes careful empirical design operationalization and measurement 10 . The research design in this study was undertaken in the same e-learning context and using the same respondents to measure the constructs of TAM and PCI model. The findings of this study provide a preliminary test of the viability of the two research models within the context of e-learning websites. Analytical results indicate that the PCI constructs explain slightly more variance in users intentions of continued use than the TAM antecedents. Both the PCI and TAM perceived constructs are highly reliable and have considerable prediction power in terms of exploring a user s continuing intention to use e-learning websites. However the TAM model has fewer measurement items 12 than the sort-form PCI instruments 25 . The TAM model places fewer strains on respondents and researchers than PCI model. The results of TAM model demonstrate that the perceived usefulness construct plays an important role in predicting users intentions of continued use while the perceived ease-of-use has a significant impact on it. Conversely the PCI results report that while relative advantage construct plays a critical role in explaining the intentions of continued use trialability and compatiability constructs are also significant. Hence teachers or marketing staff can try to enhance the innovation perception of trialability and compatiability in addition to the perception of relative advantage to raise the continued use of e-learning websites. The study also adds to the literature on comparing performance of TAM versus PCI using data gathered in a naturally occurring and field-based adoption process. References 1. Bahreininejad A.
