The education has been developed with a content and disconnected logic, without a direct relation with the social environment. The new methodologies of education should make a relation between what is learned in the classroom and what the student experiences in his daily life. Constructing a technical high school where the theory and practice are interconnected would probably generate a greater understanding on the part of the students and a greater insertion in the labor market in the chosen área. This work aims to verify if practical experiences in the classroom help the learning in the component Mineral Concentration in a regular mining course of the Federal Institute of Amapá. Theoretical and practical classes of the same content were given in identical and compared classes. There seems to be a learning in both ways of teaching, according to the results obtained. Traditional learning seems to arouse less interest than the (practical) differential, making it appear that there was greater retention of knowledge due to lower error rate. It seems that allying traditional to practical teaching would improve the learning rate in the Mineral Concentration component of the Federal Institute of Amapá.
