Abstract
Recent developments in pedagogy have focused upon computational thinking. Computational thinking provides a way to solve the problem and it is a key practice of science education. The importance of computational thinking is rarely found in K-12 education. Computational thinking is a an important skill everyone needs and it is correlated with many other concepts. These factors have made the development of new tools and syllabus. In this paper, we aim to show the experiments of fractal geometry using MIT Scratch. These computational exercises facilitate to learn many of computational thinking skills that are very important for the people in the near future. Based on our experience with students, we claim that the concept of fractal and its implementation in MIT Scratch is the best practices to improve computational thinking in K-12 school level students.
