Dear teacher, this Potentially Meaningful Teaching Unit is the final product of my Master's research, and was tested in a second high school class of a public school in Manaus (Amazonas, Brazil), composed of thirty-three students of which two are deaf. It is a support material aimed at teachers who teach in inclusive schools (or not), a teaching material aimed at teaching geometric optics through the theme "Problems of vision and corrective lenses", suggestions for methodological practices, simple experimental activities, supporting texts, script of activities, tests and assessments. I hope this book can help you to provide a better teaching to your deaf and hearing students and facilitate your work.
