Problem-Based Learning Using Mobile Devices

Small handheld devices such as PDAs and smart phones become more and more popular. Thus, we are seeing a growing number of projects using mobile devices for educational purposes. Due to the limitations of screen size, CPU performance, and memory size, software development for mobile devices is challenging. More critical argument is about the lack of pedagogic and didactic concepts on the usage of mobile devices in education. In this paper, we present a system using mobile devices which supports research experiences for students in a laboratory context. The system allows students to efficiently monitor and control their scientific experiments at anytime, from anywhere. We describe several usage scenarios in the area of nanoscience studies, where the remote control of microscopes is mandatory. We present our system architecture and describe the implementation based on open-source software.
