The Importance of Blended Learning for a Technical Drawing Classes

Abstract

This study aims to investigate the effects of computer-based training on technical drawing classes. The graphic representation provides the logical link between thinking, imagination and objective, material reality. It is fundamental for student’s to understand of constructive forms, functional and assembly schemes. This requires the use of classical teaching methods which is based on the application of internationally recognized standards, being necessary for the correct application of the principles for a technical drawing. In terms of improving the quality of the communication channel between teacher and student in recent years teachers have turned to modern teaching methods using simulation as an instrument underlying the student's understanding of the required tasks. In the least years we found out that using computer-based instruction (CBI) at classes give more favorable ratings for students. Interactive animations and simulations supported with computer aided teaching, used for presented some problems had a positive effect on the achievements of students. The use of modern teaching techniques is integrated into curriculum education as a frequent trend of developed countries for university and pre-university environments. Teaching using computer-based instruction has a very good impact because increase the students’ achievements but we find out that is not enough. As for the technical drawing, the use of simulations and presentations like a modern teaching method is not enough to form a technical thinking. Thus, it is necessary to apply the classical methods of teaching, which are aimed at understanding the necessary steps for the creation and realization of a technical drawing which can be conceived only on the basis of the international conventions established by the engineering graphics.
