Abstract: In traditional in-the-field activities, most elementary school students can only work with basic inquiry problems owing to the lack of appropriate supports. The advancement of mobile and wireless communication technologies has provided the opportunity to cope with this problem. In this study, a design model for developing a ubiquitous PBL system (UPBLS) is proposed for helping students refine their intuitive problems to become data-based inquiry plans. The system developed in this study provides a discussion platform, an E-library and an ecology measurement database for the collaborative inquiry community. The present results obtained by analysing the students' learning profiles show that the students were well supported in refining the questions they raised from basic questions to data-based scientific questions, with the help of UPBLS. It is concluded that the quantitative approach might provide a productive direction for further studies to integrate different groups' portfolios.
