Space perception is necessary for work in branches of technology from the machine industry to civil, electrical, and material engineering. The spatial perception of students coming to technical universities is not highly developed. There are several reasons for this unfortunate situation: firstly, the lack of emphasis put on geometry and other subjects developing this kind of perception; and secondly, the perception of our life as flat such as viewed on television. At primary and secondary schools it is essential to support subjects enabling one to "experience" space, mainly geometry, graphic, and plastic art education, technology education, geography, etc. As for teaching geometry, it is necessary to renew its importance, firstly by better using present curricula (teacher's approach, using models, etc), and secondly by reintroducing geometry at schools where it has been abandoned. Visualizing three-dimensional objects and functions by a computer (rendering) is the latest highly effective method. The concept of the third dimension is met when working with a map in geography as well as in everyday life. The new method (Comparative Geography) is using a mountain altitude measure based on its comparison with a referential mountain. Its objective character, easy memorizability, comparability, and possibility of making altitude scales contribute to better and more frequent perception of the third dimension in the countryside. In arts and crafts, three-dimensional objects are used both directly (clay, wood, metal) and indirectly as when they are transferred to two-dimensional ones when drawing (perspective, contrast of light, color contrast). These disciplines have also been negatively affected by reducing their extent and decreasing their importance. Learners can acquire space perception better if a multi-disciplinary approach is used in education involving disciplines like art and emotional education. In this way, space perception can be enriched with a human dimension that influences not only a teenage learner's cognitive processes but also volitional acts. This principle, applied in some alternative schools, is used very little in the traditional educational system. Nevertheless, it is a developed way of applying an old J. A. Komensky principle: "We should perceive by senses as much as possible." (Author/SAH)
