INTRODUCTION Finke 1980 We can perceive objects using mental imagery. Mental visualization of two dimensional and three not only when we look at them but also by recalling them. dimensional objects is an essential skill in many disciplines Thus imagery and perception can function alike Finke. including design architecture art science and engineering 1980 Shepard 1984 Through perception we develop an. Designers transfer the mental imagery of their design ideas understanding of our tangible surroundings Accordingly it. onto two dimensional 2D and three dimensional 3D is important to study how beginning level interior. illustrations Using those illustrations they communicate architecture students perceive walls columns and furniture. their ideas and design solutions to their clients colleagues that are drawn in 2D For example it is vital that students. and contractors Thus it is important to explore how are able to perceive a line drawn on a 2D drawing as a 3D. interior design students develop skills to create mental wall and not merely as a line How do students create 3D. visualizations of 3D objects and environments and how mental visualizations while working on their 2D technical. they develop their technical drawing skills This study is drawings. focused on how Interior Architecture students develop In the interior architecture program where the study. their skills to mentally visualize 2D and 3D representations took place students take courses to develop their technical. of interior settings and create technical drawings to drawing skills They are expected to be able to draw objects. communicate their design ideas Using qualitative research correctly from different views which requires an. methods we aimed to answer the following questions 1 understanding of the relationship between shape and form. How do students develop their skills to visualize 2D designs That understanding is related to visual thinking spatial. in 3D and how does this process affect their overall design visualization perception and 3D mental visualization. process 2 How do model making and computer aided Visual thinking is important in design and problem. design influence this process The findings allowed us to gain solving whether it is in the field of product design Dahl. a better understanding of the student learning process and Chattopadhyay Gorn 1999 architecture Kavakli. discuss ways to improve teaching strategies in the interior Gero 2001 Yagmur Kilimci 2010 engineering Bertoline. architecture education et al 1995 Ferguson 1992 Potter Van der Merwe. 2001 or computer science Casakin Dai 2002 Petre, RESEARCH BACKGROUND Blackwell 1999 Slack 1984 stated that research on visual.
