This study designed a system and a flow of learning to motivate and guide students to conduct experiential learning with mobile technologies. Students from two classes of fifth-grade at an elementary school participated in the experiment. Thirty-four students from one class conducted learning with PDAs in school garden while thirty-two students from another class conducted in a condition without PDAS. The data shows the advantage of using mobile technologies for the acquisition of knowledge. Most of our hypotheses are confirmed in the study. These findings show just how important mobile technology is in helping to improve the learning achievement of experiential learning.
