LOPEZ VARONA, Eduardo e MORCIEGO GARCIA, Carlos Eralio. Instructional compression technique to obtain orthogonal views. trf [online]. 2019, vol.15, n.2, pp. 171-185. ISSN 2077-2955.
Objective:
First, the authors aim at exploring students’ difficulties to obtain the orthogonal views from the isometrics or the real models, both at the Technological University of Havana and at the University of Camagüey. The main objective was to describe a set of procedures for obtaining orthogonal views of real objects or models in the subject Drawing.
Methods:
The methods of analysis and synthesis were used for the construction of a theoretical frame, modeling was used for the design of the instructional technique proposed and a quasi-experiment to evaluate the effectiveness of this technique in this subject.
Results:
The techniques for obtaining views according to the European and American systems are described, an instructional technique is proposed to obtain these views and its pertinence for learning is demonstrated from the realization of a quasi-experiment.
Conclusions:
The outcomes of the carried out quasi-experiment confirmed that the proposed technique, which essentially consists of compressing the body until it is arranged in a single plane, favors the understanding and the use of the students.
