RESUMO:

The concept of orbital is of fundamental importance for the teaching of Chemistry, since the understanding of quantum theories of chemical bonding depend on the understanding of the concept of orbital. However, concepts important to your understanding as: (a) quantum of a greatness; (b) the dual nature of matter and radiation; (b) atom as structure; (c) electronic movement without trajectories defined; should be taught previously. The literature consulted indicates that the students have difficulty understanding the concept of orbital even after of their teaching. Therefore, the objective of this work is to investigate how the process of formation of the orbital concept in higher education students in a historical-cultural perspective. The class took a historical approach to the concept of atomic orbital, since Vigotski (2001) affirms that historical analysis makes the concept logical. In addition, the students were led to solve exercises, so that in this way the concept use in problem solving was observed. 

It is investigation of an empirical nature, of the Action-Research type, was carried out in the 2016.1, 

of the discipline QUIA49-Quimica Quântica I which counts with about 35 students, among undergraduate and 

bachelors in chemistry). Content Analysis, will be used to analyze the data obtained with the survey, 

solved exercises, assessments, observation and filming of classes. Initially, a to perceive the students' 

spontaneous conceptions about the concept of atomic orbital and the probabilistic interpretation of the 

wave function and as result was obtained that the students in their majority used more the terms referring 

to the concept of orbital as a region of space and also for them the probabilistic interpretation can be

 interpreted as the probability density of finding the system in a given region of space. 

From the analysis of the video it was possible understand how important the teacher's work is for 

therefore learning the concept, because only someone more experienced is able to act in the zone

 of imminent development and making the student take a cognitive leap and become aware of the concept. 

The evaluations served as problems in which students would have to demonstrate that they became aware 

of the concept of orbital. According to the terms used in the answers given, possible to verify that there has 

been a development of the higher functions of the students. Through this research it was possible to perceive that a teaching in which encouraged to discuss, write and solve problems, cognitive development of this student
