The purpose of the present research is to investigate the effectiveness of a hyper interactive 3D application, named HENASTRON2, implemented in a unity environment, as a didactic tool in teaching astronomy topics and specifically the phenomenon of the existence and alternation of seasons. The hyper-interactivity of the application focuses on the one hand on the direct multi-level interaction of the users with the application at all stages of a teaching intervention and on the other hand on the multimodal presentation of the teaching material, giving the users the possibility of self-regulating the learning process. A number of 35 students, prospective teachers in primary schools, participated in this pilot study. The research was conducted in the context of the academic course of astronomy, a subject included in the primary level school curriculum. The teaching intervention is based on the exploratory approach to learning and the students’ answers are stored in a specific database and are available to the teacher in real time. For validity and reliability purposes, a mixed method approach (quantitative and qualitative) was used in this research. The results have revealed that the implementation of a self-regulated learning process can be effectively achieved through the use of a well-designed application in a 3D environment with strong user interaction characteristics.
