This study proposes a web-based collaborative inquiry learning system. This system uses the World-wide web (WWW) as a source of knowledge exploration, and provides exploratory problems to guide students to think and explore. A concept map is used as a tool of anchoring and representing knowledge during inquiry process. In the process of learning, learners are allowed to exchange the evidence they have collected, their personal opinions, and the concept maps that they have built. In order to effectively integrate the inquiry learning, collaborative learning, and concept map in the system, this study proposes a collaborative inquiry learning model and related learning activities. Two studies were constructed based on the collaborative inquiry learning model to investigate students' learning processes in the collaborative inquiry learning on the web.

1997 theory, structure theory, structure C 1000 -003Ab initio Calculations on the Structures and Energetics of Li4OH, Li3NaOH, and Li2Na2OH Isomers.-Ab initio calculations show the existence of five equilibrium geometries for each complex of Li4OH and Li3NaOH and locate seven minima for Li2Na2OH. The global minimum structures have C2v symmetry and contain a Li-H-Li hydrogen-bridged three-centered skeleton. -(LEE, C.-L.; SHEU, M.-J.; SHIE, Y.-S.; WU, D.-H.; HO, J.-J.; J. Phys.
