Abstract
The authors developed a cellular phone application which displays information regarding progress and achievement of the tasks and division of labor in project-based learning in higher education. The ProBoPortable application works as wallpaper on the learner's cellular phone screen, and cooperates with a Web-based groupware. When a learner activates his/her phone, ProBoPortable immediately retrieves the current status of the project from the groupware database and displays the status on the screen. Classroom evaluation was performed in an undergraduate course, which confirmed that ProBoPortable enhanced mutual awareness of the division of labor among learners. Moreover, since the sense of community was increasingly generated, learners were encouraged to proceed with their own task because they were aware of the status of others' tasks, as and when necessary.
