Web collaborative exploration learning has become much critical in education approaches because it facilitates learners with access to various information and opportunities to learn collaboratively with peers. Shared-computer is increasingly used to support web collaborative explorative activities because learners can be facilitated to promote shared understanding of the workspace and enhance effective communications. However, implementing shared-computer can also be inefficient and frustrating because learners have to spend extra time and cognitive resources to negotiate with the web search. This may discourage learners to positively participate the activity. Hence, the study proposes a the 1:1 group (shared-computer integrated one person for one computer) so that learners can individually search web information with their personal laptop according to their strategies and preferences, and then use shared-computer to share their information and interact with peers. An empirical study involved nine graduate students is conducted to examine the learner's interaction behaviors in two scenarios: 1:1 and shared-computer. The result shows that the 1:1 group can better benefit participants' in-depth interaction due to the autonomy of personal web search strategy and preference.
