The present paper reports on online collaboration support tools for a blended and project-based learning (PBL) program. The authors have been conducting a research project in an attempt to implement e-Learning technology for project-based learning on the development of embedded software, and reported several times on each of the tools and the learning program. This paper corresponds to the final report of the research project, which clarifies the position of each tool and provides evaluation results and discussions. The tools proposed and developed include integrated repository, review support, online white-board, and postmortem support tools. A project-based learning program has also been constructed on the premise of use of those tools. A trial of the proposed program has been carried out, then a questionnaire survey and an achievement test have been conducted to evaluate the learning effect of the program and the tools. The results suggested that the program is feasible for PBL on embedded software development, and the tools facilitate collaborative activities between learners and are effective for enhancing their ability.
