Abstract

The aim of this research is the development, implementation, and evaluation of a Teaching Learning Sequence (TLS) for secondary school students, focusing on the applications of nanotechnology-nanoscience in medicine. Its goal of this TLS is to familiarize students with fundamental concepts such as size and scale, surface-to-volume ratio, and to help them understand the significance of nanotechnology in medicine, particularly in the diagnosis and treatment of diseases like cancer. Additionally, students were informed about potential risks to human health and the environment, as well as ethical issues that may arise from its use.
