摘要：Digital devices like smart phones, tablets, PDAs and GPS navigators provide teachers in primary and secondary schools with new and attractive chances to teach in a constructivist/constructionist way. The research was aimed at designing an engaging outdoor learning activity based on collaboration and active using of mobile technology. The suggested learning activity was inspired by a real-world treasure hunting game called Geocaching and was realized with 2 groups of pupils aged 10-14. Children used a GPS-enabled PDA to navigate from their current location to another. They encountered various types of problems while collecting hints needed to calculate the final location of a hidden container. Even collaboration between competing teams was necessary in order to succeed. The case study gives an example of a well-designed constructivist/constructionist learning activity with special focus on informatics education but can be easily adapted for using in any other school subject or some after-school context as well. The adventurous and competitive nature of the learning activity resulted in high intrinsic motivation to learn, so the educational objectives could be reached effectively. Reported findings are grounded in observations made during the learning activity as well as the interviews with participants.
