Student Visualization: Using 3-D Models in Undergraduate Construction Management Education

Three-dimensional computer models used in the classroom may help increase student understanding of new and complex course material, and provide an opportunity to enhance visuo-spatial skills. Students lacking these abilities may have difficulty visualizing construction systems and components. This study explores the results of a survey conducted in the Fall of 2009 as part of a curriculum development project in the Construction Management Department at one University. Over twenty 3D models were created from figures in the course text and used, to varying degrees, in three sections of a materials and methods class. Focusing on four CSI divisions, the results indicate that students' perceptions of learning masonry (F (2,123) = 12.01, p = 0.001) and metals (F (2,122) = 3.6, p = 0.031) increased when 3D models were part of the course material presentation. The results were also used to direct resources for additional 3D model development.
