This research integrates the concept of mobile learning and math path. Learning mathematic is no longer an abstraction but a connection of real life. Besides using cognitive apprenticeship as the learning strategy in the activity, we also combine the learning activity with local culture. The experts will support the students learn in the learning process and provide a novitiate to them. Mobile learning supports every learning task in the math path and smoothes the interactive problem solving and demonstration. Students also obtain sense of achievement immediately in the learning environment. Cognitive apprenticeship emphasizes that students attain a meaningful learning via the social interactive activity. In this research, school is the learning environment, math path as the context, and wireless network and tablet PC as tools to support mathematic learning. We also evaluate the learning performance of junior high school students with the strategy.
