Our organization is a private school of secondary education in Klaipeda, Lithuania. Its total number of students in the school year 2015-2016 is 476. Its educational staff has 80 teachers, 24 of whom are on STEAM (science, technology, engineering, mathematics, arts, theatre) subjects. Our school has a professional development plan in order to improve the competences and skills of its educational staff. The main areas of improvement that were identified are: to enhance and strengthen their digital competences, to learn and familiarize themselves on the use of e-learning and e-teaching tools and online resources, to learn, develop and acquire knowledge to implement inquiry-based science education methods and other innovative teaching methods and best practices in STEAM (creative science-technology-engineering-mathematics) domains. With this application we will support the participation of our school's educational staff in training activities organized within the framework of Erasmus+ that will give them the opportunity not only to learn and develop their skills but also to meet, to collaborate, to cooperate, and to share experiences, challenges and methods with colleagues from other European countries. The competences, skills and experiences that our school's educational staff will acquire by participating in the project/training will be fully acknowledged, accredited and integrated into their professional development track record which is taken into account for professional promotion to higher rank. The participant teachers will be selected by a selection committee that includes the school's principals and the heads of science teaching department through individual interviews that will guarantee the best match between the course's objectives, applicable prerequisites to participate, and participants skills, proven and expected competences and needs according to the school's future development plan. The training courses and job shadowing activities consist of preparatory and follow-up phases in addition to the actual course period which is a week or two week-long intensive course that includes keynote lectures, workshops, social/parallel activities. The learning objectives and outcomes will be assessed and documented in an evaluation report. The impact of the course is that the participating science teachers will be immersed in the process of science-inquiry via their interaction with collections of digital educational resources, tools, online labs and be exposed to innovative best practices linked with the science curricula applied in their country but also increase awareness of developments that are taking place in other European countries. The impact will be felt not only by science teachers, but also other teachers, students, and the rest of the school community in modernization of the teaching process on the whole.
