9 directly, either coming from something they can easily relate to or to point out bigger societal issues, is the first step toward keeping their interest on a high level. Preparing stage two, which is committed to the core of the lesson, with hand-on activities as a priority has higher potential to keep their interest going throughout the lesson, rather than losing their motivation and concentration in an abstract theoretical narration. In stage three they should acknowledge the meaning of the lesson and the impact this new-gained knowledge has either for their personal life or for them, being an important part of the society. Pupils should see themselves as an important link that is constructing the future and see beyond the passive role. They should understand that the future to come is in their hands and that only their active role will lead toward a future, they would appreciate and like to live in. The three stage model as it is developed in OTA methodology leaves a lot of room for teachers to implement their lessons. Following the suggestions should serve as an inspiration on how the subjects they are teaching can be approached. With explanations of different learner-centred methods and approaches in teaching, teachers should explore their options and reflect on how to use art as a tool when teaching science. Further on, OTA being an up to date project is also addressing the barriers, teachers and pupils were facing, when pandemic hit the world and schools were almost immediately moved in a home environments for pupils as well as for teachers. Therefore, an on-line teaching and learning are addressed and implementation of the activities in an on-line environments is taken into a great account. With the digital era, we live in and counting the fact that on-line learning existed even before the pandemic, we can assume that in a post-pandemic world at least some forms of online teaching and learning will continue. Having strong bases and being prepared for this type of teaching and learning is an undeniable investment, especially now, when we experienced the worldwide situation of on-line education in all levels and are well aware of what kind of troubles it presents for educators and students. 2.2 STEAM METHOD STEAM Science, technology, engineering, arts, and mathematics. By now, the term STEM has already become a well-known term, which is connecting related subjects and can also be found in formal education around the world. Lately STEM got a new form – STEAM. STEAM is a method that is promoting interdisciplinary teaching, specifically for science subjects in combination with art. As the research in IO1 showed – a lot of teachers are thinking in favour of interdisciplinary teaching, but the majority is not familiar with the term STEAM. STEAM approach has been a
