Prof. Dr. Birce ARSLANDOĞAN, the Assistant Director. The book's goal is to contribute to the literature and suggest scientific methods and programs to improve students' knowledge and experiences in academic disciplines in the most accurate manner. The book contains a wide range of topics, such as art, speech, development, health, sports, management, leadership, social and emotional developments, technology, foreign language, and nutrition. The diversity of topics increases accessibility by ensuring a broad framework of scientific knowledge. Learning and education contain an emotional dimension. Children are passionate and open-minded.
