STEM approach aims to help student have an interdisciplinary view on problems, and gain knowledge ans skills with a holistic educational approach. Therefore, it is very important to determining the subject that can be lectured together with other courses in every education program and design of integrated course activities in the integration of STEM education in different courses. Coding is considered as the most important part of the Technology section STEM, and coding is also covered while mentioning STEM in tehe project. While conducting all these works for curriculum, the curriculum for technology should be created especially with the coding logic. After deciding these two implementation parts of STEM education, the theories supporting these practices in Science and Mathematics should be determined. Bu yaklaşımı okullarında uygulayabilecek STEM eğitimi ile ilgilenen öğretmenlerin bir araya gelerek disiplinler arası STEM eğitim projeleri geliştirme ve uygulama ekiplerine doğrudan ihtiyaç duyulmaktadır. Bu ihtiyacı karşılamak amacıyla STEM ve Kodlamaya yönelik eğitmen eğitimlerinin yapılmasına ihtiyaç duyulmaktadır. Within this project it is aimed to prepare innovative educational programs in order to standardize the STEM and Coding practices which currently varies from region to region. These programs will define the content, duration, participants and the activities of the trainings. Therefore it is aimed to observe the good practices of STEM-Coding in Europe and receive trainings from the European Schoolnet which is a leading organization in STEM and Coding. After these trainings are organized and received, all partners will prepare the STEM and Coding Trainer Training Programs to be implemented all over the country. Meanwhile, it is aimed to prepare guidelines to be used during the process and produce STEM and Coding course plans and activities. YEĞİTEK will organize two pilot trainings in order to evaluate the functionality of the educational program and the guideline. These two pilot trainings will be given by project training team which is certified after completing the trainings provided by the European Schoolnet. This team will give two trainings to 20 teachers of each course who are experienced in teacher trainings and worked for the Ministry in different projects. Second pilot training will be given by 40 teachers to 400 teachers on STEM and Coding. These trainings will be organized in 10 cities who are leading in the STEM and Coding activities. After the pilot trainings the STEM and Coding program and guidelines will be ready. YEĞİTEK will coordinate the dissemination works after the updates. Since the STEM and Coding In-Service trainings need to be academically successful, easy to be implemented and compared internationally the partnerships are formed between the institutions which can implement the project effectively in Europe. During the implementation of the project: Trainers accredited and experienced in providing trainings on STEM and Coding will be raised. Besides, an educational program to be used by these trainers will ve provided. Trainer guidelines for the implementation of the educational program, contents and sample STEM and Coding activities will be produced. Also aweb platform to be used under the Educational Informatics Network (EBA) for the promotion of the project. Also there will be a special session and promotion for the project at the FATIH Project EDucational Techologies Summit whih is organized every year with the great national participation. After completiıon of the project successfully; An educaional and feasible model for STEM and COding education nationwide will be created. Benfiting from this model, STEM and Coding trainings will be provided in order to enable teaches receive professiobnal development opportunities. Also it will enable teachers to create projects with their students. There will be contest organized in order to promote the projects prepared on a national level. STEM projects jointly prepared by teachers and students will be exhibited. In this way, teachers and students will be motivated.
