The purpose of this research is to improve learning effectiveness of architects and civil engineers in first three years in the courses ‘Engineering Graphics’, ‘Descriptive Geometry’ and ‘Computer Graphics’. This case study traces the structure and strategy of lectures and the relevance of different kinds of educational aids in graphical education in Riga Technical University, Latvia. The author analyzes different themes of learning the subject and the content of inherent information according to cognitive knowledge dimensions. According to teaching functions - learning assistance and skills development, providing experiences and nurturing different parts of multimedia kit - different teaching technics, educational aids and multimedia materials are used. The observations when it is preferable to use blackboard or whiteboard, or interactive whiteboard, when is better to use PowerPoint for demonstration or animation, and when professional drawing programs like AutoCAD and models - physical and digital should be used are described. An opinion about propotion in which technical aids, beforehand prepared teaching printed matherials and human mediation during the lecture should be used is expressed. The analysis of roles and activities of subjects collaborating in educational process - lecturer and students as well as activities advisable for each of them in lecture, practical work or individual tasks follows. In this paper the experience of Department of Computer Aided Engineering Graphics at Riga Technical University, Latvia is described. Practical implications include hints on what kind of aids is more suitable for several themes and which aids are usable for most of the themes.
