Development of a tool for teaching natural history and deep time within the framework of biodiversity

Natural history; It is a science based on field research that includes many sciences such as astronomy, geology, archeology, paleontology, biology, ecology, ethology, zoology, geography, systematics, genetics, covers the abiotic and biotic elements of the Earth, and uses comparative and descriptive methods to understand the relationships between these elements and how these elements evolved, and is the story of understanding nature. In order to understand the changes in the diversity of life in nature, deep time must first be perceived. Perceiving the importance of the Earth and biological diversity becomes difficult when the deep time that has passed cannot be understood. Therefore, this study aims to teach the concept of biodiversity, to explain the changes in the diversity of life and extinct creatures on a timeline. In the development of the teaching tool for this purpose, an interactive "DTÖA is an important tool that plays a key role in the perception of deep time in biodiversity teaching." (DTÖA) was developed with the Google Slides program, based on the ADDIE teaching design model. The teaching tool developed consists of interactive visuals and texts expressing the events taking place on a timeline. The teaching tool is an easily accessible tool that can be used both during and after the lesson, and supports individual learning without the need for any practitioner when there is internet. This WTÖA significantly provides the perception of deep time, which is key in teaching biodiversity.
