ABSTRACT
The teacher as an educator plays an important role in the process of forming a concept image of students about the equal sign in learning mathematics. Teachers must have an equal sign meaning in accordance with the capacity, learning experience, and knowledge which is a source for them to compile a certain didactic design. The didactic design that has been compiled becomes a learning environment that triggers students' mental perceptions and actions so that a concept image of the equal sign is formed. This study aims to explore teachers' understanding and confirm that the concept image formed by these students may be the impact of the learning process with didactic designs that have been compiled by the teacher. The investigation was conducted qualitatively using a case study approach involving 6 teachers and 55 elementary and middle school students. The data collection methods included teacher questionnaires and interviews with two selected teachers, as well as students answering a series of questions then six students were deliberately selected to be interviewed based on their responses. The results show that the teachers' concept images about the equal sign are generally difficult to say that they already have a well-developed relational view, in addition, they lack the knowledge and skills to identify, anticipate, reduce, or correct students' misconceptions about the equal sign. As a result, the majority of students do not have a concept image about the equal sign that matches the scientific conception that should be.
