The data of the study were collected with a semi-structured interview form created by the researchers. As a result of the research; the vast majority of biology teachers; They stated that they sometimes benefited from concept maps while providing the formation and development of biophysical concepts in their students. Again, the majority of biology teachers; They stated that they often found it necessary to benefit from concept maps while providing the formation and development of biophysical concepts in their students. Biology teachers participating in the research, while providing the formation and development of biophysical concepts in their students, the positive aspects of benefiting from concept maps; They categorized the subject as providing better learning, improving the thought system, establishing relationships between concepts, making the lesson more enjoyable and facilitating the learning of key concepts. While biology teachers participating in the research ensure the formation and development of biophysical concepts in their students, the negative aspects of using concept maps are; They categorized it as difficulty of preparation, not being a very effective method and not appealing to every student.   Keywords: Biophysical concepts, concept map, biology teachers
