In the teaching process, two basic false beliefs appear as important obstacles to understanding. One of them is that success in central exams is seen as an indicator of effective teaching and therefore, achieving success in central exams is a goal in teaching. Another false belief is that the purpose of teaching is to gain content. This situation causes teachers to aim to convey the content, make an effort to catch the curriculum and measure the content knowledge. However, permanent learning of the student is possible only by understanding and it is a multi-dimensional concept beyond knowing. Understanding Based Design (UbD) provides meaningful learning by incorporating all dimensions of understanding, aiming to develop students' 21st century skills, supporting their individual differences, revealing their performance, and providing students with the opportunity to transfer information to real life. This book is a guide for teachers, academics and graduate students who want to make an UbD. It is an original book in the field of instructional design in terms of covering the applications within the context of the 5th Grade Social Studies Course alongside the theoretical information about UbD. The book includes the UbD design examples of the 5th Grade Social Studies Lesson units as well as the application results of the designs in İzmir and Kahramanmaraş. In this way, it is thought that the book will guide not only Social Studies teachers, but also educators who want to design UbD and make the teaching process qualified and facilitating.
