The paper emphasizes the importance of using mental mapping technique in Science and Social Studies Teaching. In the first part of the paper, the theoretical assumptions about mental maps, their application in teaching, that is, in the education process, are considered. In the second part of the paper, the results of a research conducted by surveying teachers and students of Teacher Education Programs is presented. The aim of the conducted research was to determine the level of knowledge of teachers and students of Teacher Education Programs about the characteristics of mental maps. Additionaly, it aims to assess the level of knowledge about mental maps and the modalities of their creation. Insights are given into the opinion of teachers and students about the use of mental mapping techniques in the teaching of Science and Social Studies Teaching. The goal is to determine how teachers and students assess their personal competences for teaching Science and Social Studies in which students create mental maps. Research is carried out among 107 teachers and students of teacher studies during the months of January and February 2024. Results obtained show a high level of knowledge of teachers and a medium level of knowledge of students about the characteristics of mental maps. The results showed a very low level of knowledge of teachers and students about the peculiarities of mental maps making process. It was found that teachers, as well as students, have a positive opinion about the usefulness of using mental maps in the teaching of Science and Social Studies. However, it is observed that the students are somewhat indecisive when assessing their personal competencies for implementing the aforementioned techniques in teaching, unlike teachers who better assessed their own abilities. No statistically significant difference in knowledge was found among the groups of students regarding the type of their high school education. Likewise, it has been proven that the level of knowledge about online tools for creating mental maps does not depend on the students' module. Those respondents who had had a positive opinion also had better assessed abilities, that is, a positive correlation on that subscale is present.
