Outdoor learning activities are very time consuming for teachers to prepare and difficult to manage, especially when the activity takes place in a non familiar environment for instance zoos. M-learning could help teachers to conduct outdoor education by involving learners in the creation and orchestration of artefacts (game). For that it is necessary to know how to arrange, orchestrate and monitor such diversified forms of learning in a systematic and technical manner. In pursuit of these goals to reduce teachers workload and share part of the orchestration load to students a case study was conducted where 9 students and 3 teachers participated. Together with the teachers and the Zoological Gardens pedagogues, the activities were planned, where the learner could acquire the knowledge through playing and creating the tracks, consisted of location points with assignments. The created activities were also tested in practice to determine their suitability for use in real life learning conditions. For creating activities and learning at the Zoo, SmartZoos app was used. It is a game based learning app where users move from one location to another with the guidance of their phone and in specific location points tasks open that learners need to fill. Students were divided to groups and every group was followed by an observer who took notes about occurring problems and time spent using the phone. Students and teachers evaluated their experience by answering questionnaires, additional interviews were conducted with the teachers to get a deeper understanding of their perspective to sharing orchestration load with students and how they managed the groups at the zoo. The results of this case study show that students were successfully engaged in the planning and creating learning artifacts stage, reducing teachers workload and planning time for this outdoor learning activity. The main issues that teachers brought out were group managing, communication with students for example following students movement, having access to students work or results and assessment.
